Issue 7 November 1998 Product Description 2 - 1 2 Product Description Overview Lucent Technologies IR Series I batteries are configured in two different ampere-hour capacities that are engineered to meet specific and often unique application requirements: IR-30EC and IR-40EC. The valve-regulated design and construction of the IR-30EC and IR-40EC batteries prevents electrolyte leakage and minimizes water loss and maintenance throughout the design life. During normal operation, oxygen is generated at the positive electrode and hydrogen is generated at the negative electrode. In conventional (flooded) lead-acid cells, these electrochemical reactions result in water loss from the electrolyte. The self-resealing pressure release safety valves in IR-30EC and IR-40EC batteries are designed to aid in the electrochemical recombination of nearly all the oxygen within the battery. In addition, the safety valves prevent the build-up of excessive internal pressure. The IR-30EC and IR-40EC batteries comply with the requirement for sealed battery/cell pressure release test of UL1989, Standard for Standby Batteries. Features • High energy density • Leak-resistant post seals • Flame arrestor • Flame-retardant 94-V0 polypropylene container and cover • Metal sleeve

Issue 7 November 1998 Safety and Environmental 4 - 1 4 Safety and Environmental Safety Symbols Safety Precautions Read the following safety precautions carefully before attempting to handle, unpack, and install the batteries. Fully brief everyone with access to battery areas, or who are working near or with batteries, on the hazards associated with lead-acid batteries. Additional information can be found in the Material Safety Data Sheet (MSDS) in Section 11 of this product manual. Poison HIGH VOLTAGE... RISK OF SHOCK. DO NOT TOUCH UNINSULATED TERMINALS OR CONNECTORS. SHIELD EYES. SHIELD EYES. EXPLOSIVE GASES CAN CAUSE BLINDNESS OR INJURY. GASES NO SPARKS FLAMES SMOKING SULFURIC ACID CAN CAUSE BLINDNESS OR SEVERE BURNS. FLUSH EYES IMMEDIATELY WITH WATER. GET MEDICAL HELP FAST. DANGER POISON CAUSES SEVERE BURNS Valve-regulated batteries contain toxic materials (lead, lead compounds, and sulfuric acid). Do not incinerate or mutilate. Avoid contact with skin, eyes, or clothing. Recycle batteries in approved reclamation centers according to local, state, and federal regulations.

4 - 2 Safety and Environmental Issue 7 November 1998 All lead-acid batteries contain electrolyte (sulfuric acid and water), a highly corrosive substance. Lucent Technologies valve-regulated batteries are designed so that the electrolyte is absorbed by the plates and separators. Electrolyte ordinarily should not leak outside the battery container. However, it is possible that certain types of physical damage and/or abusive charging may force small quantities of electrolyte outside the battery container. Lucent Technologies valve-regulated batteries are safe; however, accidents can occur. • When handling batteries or cells, wear protective equipment (e.g., acid resistant rubber gloves, acid resistant rubber aprons, and impact-resistant, splash-proof goggles or full face mask). • Even when not handling batteries, wear splash-proof and impact-resistant goggles while working around batteries or on equipment containing batteries. The MSDS in Section 11 contains information that everyone needs to understand before having access to the batteries, such as: health hazard summary, first aid procedures, fire and explosion hazard data, reactivity data, special protection information, environmental information (spill clean-up and disposal), and special precautions. The following items can be ordered from Lucent Technologies. These items should be available to anyone working around batteries. The local, state, or federal codes for certain installations may require some of these items to be installed and/or kept at the installation site. • Protective gear • Acid spill clean-up and management kits • Battery cleaning and maintenance kits

Issue 7 November 1998 Safety and Environmental 4 - 3 Electrical Hazard Batteries differ from other sources of power in that they are delivered to the points of installation as live units. A battery gives no indication by its appearance of the potential energy stored in it. Batteries have enormous short circuit capability that can result in serious burns or create dangerous projectiles from the object causing the short circuit. • Exercise extreme care to avoid any short circuits across the battery terminals. • In a grounded battery system, use extreme care not to short any metal objects from the ungrounded battery terminal to ground (which can include the equipment metal chassis, building structure, cable racks, etc.). • Even a single battery poses a potentially high energy hazard if shorted. Shorting a battery may result in explosion of the battery, injury to personnel, and damage to equipment. A tool or other metal object causing the short may be thrown or vaporized due to the energy produced by the battery or system. WARNING ELECTRICAL HAZARD In addition to proper job training and safety procedures, the following are some basic precautions that should always be followed when working with or around batteries (including equipment connected to batteries): • Always use insulated tools. • Never place uninsulated metal objects on top of a battery. • Remove all metal jewelry such as rings, watches, bracelets, long necklaces, and any other metallic items. • Do not short circuit the battery. • Insure proper polarity when making connections. • Wear eye protection.

4 - 4 Safety and Environmental Issue 7 November 1998 A single battery is typically at low voltage; however, batteries connected together in a system can pose a shock hazard in addition to an energy hazard. When interconnection of the batteries creates a hazardous voltage supply, post appropriate warnings in the end systems or installations. All systems and/or installations should consider the need for additional markings based on the use of the battery, industry standards, and local, state, and federal regulations. Battery Gases Valve-regulated batteries are designed to minimize the amount of oxygen and hydrogen gas released from the battery under normal conditions. However, abnormal conditions, such as high temperature, abnormal charging, shorted cells, etc., can produce greater amounts of gas. Even batteries under open circuit conditions can produce gas. If not permitted to escape, this gas can build up to explosive concentrations. Refer to Section 7, Operation, for more information on gassing rates. • ALWAYS place batteries in a well-ventilated area. • NEVER place batteries in a sealed enclosure. • Make sure the area is properly ventilated before performing any work. • Since gas generated by batteries is explosive, avoid creating sparks (including those from static electricity), the use of an open flame, or smoking near the batteries. DANGER RISK OF EXPLOSION • Battery gases can be highly explosive. NO sparks, including sparks generated by electrostatic discharge (ESD), or open flame are allowed near battery modules. Do not smoke around batteries. Make sure the battery area is properly ventilated before performing any work. • Do not place batteries in a sealed enclosure. Even enclosures with ventilation need to be properly evaluated to assure hydrogen will not accumulate to explosive levels.

Issue 7 November 1998 Safety and Environmental 4 - 5 • Before performing any work operation, follow proper ESD protection procedures to discharge the static electricity from your body. • Never tamper with or block the vent caps of batteries. Damaged or clogged vent caps may result in an explosion due to excessive internal pressure. Such an explosion could short circuit other battery modules, result in a fire, injure personnel, or cause damage to equipment. • Never charge a battery that is visibly damaged or frozen (typically at temperatures less than -40°C or -40°F). • Be alert to procedures that may create potential hazards, such as creating sparks next to the batteries. Some examples: – Avoid disconnecting the circuit at the battery terminals while the battery is being discharged or charged. – Avoid making connections at the battery terminal with the other end connected to a load or charging system (unless the circuit has been verified to be open). – If there are no devices for opening the circuit before disconnecting or connecting the battery, here are some suggested procedures: • Make sure the free end of any wire connected to the batteries is insulated until it is ready to be connected to the load or charger or immediately after being disconnected from the load or charger. • Connect to the battery terminals first before connecting to the load or charging system. • Disconnect at the load or charger first before disconnecting at the battery terminals. Freshly charged batteries may produce explosive gas. • Avoid handling a freshly charged battery within 24 hours after removing the charge. If it must be handled, use extreme caution and avoid any sparks or touching the battery in the area of the vents.

4 - 6 Safety and Environmental Issue 7 November 1998 To direct attention to the possible source of danger from battery gases, post one or more warning signs, lettered in large characters, in a conspicuous location near the batteries. First Aid Refer to the MSDS in Section 11 for first aid procedures. Lifting Information Refer to “Unpacking and Handling” in the Installation section of this product manual for specific handling instructions. Transportation and Handling New batteries are shipped meeting United Nations standard, DOT, IATA, IMDG, and other State and Government regulations. Old/used batteries should be considered as Hazardous Waste and transported according to respective DOT, EPA, OSHA, and other governing regulations or guidelines for Hazardous Waste. Environmental Do not discard batteries in trash cans. Pb Pb Valve regulated batteries contain lead, lead compounds, and sulfuric acid. Recycle batteries in approved reclamation centers according to local, state, and federal regulations.

Issue 7 November 1998 Battery Storage 5 - 1 5 Battery Storage State of New Battery The IR-30EC and IR-40EC batteries are shipped in the charged state. The open circuit voltage for a fully charged battery is 2.14-2.16V/cell. Storage Conditions • Store batteries in an upright position in a dry and cool environment without exposure to direct sunlight. • Provide adequate ventilation during storage. • Do not stack pallets of batteries on top of each other during storage. Storage Time Batteries may suffer irreversible capacity loss during long open circuit stand. The maximum that a charged battery may remain on open circuit is 6 months at 77°F. The open circuit time should not exceed 3 months if the storage temperature exceeds 90°F. The “charge by” date stamped on the shipping container is the date the battery has been on open circuit for 6 months. If batteries cannot be installed within this time period, follow the procedures outlined in Table 6-A, “Initial Charging,” and record the actions taken until normal installation can be initiated.

Issue 7 November 1998 Installation 6 - 1 6 Installation Introduction This section describes the procedures for installing the IR-30EC and IR-40EC batteries. Please review the safety precautions in Section 4 before handling the batteries. Installation Tools, Materials, and Test Equipment The following tools, materials, and test equipment are recommended for installation, operation, maintenance, and testing of the batteries: • Chemical and impact resistant safety goggles and safety hard hat • Acid resistant gloves, rubber overshoes, and apron • Lime and/or soda (sodium bicarbonate or sal soda) • Class C fire extinguisher • Cleaning cloth • Insulated socket and a torque wrench capable of measuring 40 inch pounds • Insulated nut driver • Combination wrench set, screwdrivers • Sandpaper or abrasive cloth • Thermocouple-based or infrared-based temperature measuring device • Digital multimeter (DMM) with an accuracy of 0.05 percent on the dc scale • DC power source capable of supplying a minimum of 15V per battery times the number of batteries in a string Product Manual One product manual is included with each pallet of batteries. Order additional product manuals by calling Customer Service at 1-800-THE-1PWR (1-800-843-1797). Specify Select Code 157-622-020.

6 - 2 Installation Issue 7 November 1998 Unpacking and Handling Use appropriate material handling equipment to ensure personnel safety and equipment protection while installing the batteries. Move crated batteries to a convenient predetermined area where the appropriate unpacking and handling equipment and tools are available. Specific Unpacking Instructions Inspect the battery visually for shipping damage before it is completely unpacked. If it is determined that the battery should be returned to the manufacturer, it will be easier to return at this point than if the battery has been completely unpacked. 1. Examine the shipping container and record any signs of external damage. 2. Search for any indications of acid spillage during shipment. Record any indications of acid spillage on the bill of lading before signing. In case of acid spillage, refer to the Material Safety Data Sheet in Section 11 for instructions regarding cleanup and disposal. After unpacking, immediately check again for electrolyte spills. 3. Check batteries for fractured jars and covers. Batteries with fractured jars and covers are defective and must not be used. Note Acid spillage is a valid criterion for rejection of product. Warning Wear an eye protection device and acid resistant rubber gloves when cleaning up electrolyte spills. Wash hands and face thoroughly after use. Note Fractured cases and covers are valid criteria for rejection of product.

Issue 7 November 1998 Installation 6 - 3 If a battery is found to be damaged when received, a claim can be initiated for replacement. The battery must be shipped back in its original carton. 4. Check the contents of the package against the packing list. Report any missing parts immediately. 5. The packing list includes the order number. Record this number on the “Installation and Maintenance Record.” The order number for new batteries must be recorded on this form for use in warranty validation. 6. While unpacking batteries for installation in the intended site, mark each battery with a number using an indelible-ink magic marker. Note its corresponding number and serial number in the appropriate column under “Voltage Measurements on Individual Batteries” on the Installation and Maintenance Record (see Section 10). 7. Identify all batteries that will be used for monitoring battery temperatures. Temperature measurements should be made on one of the middle batteries of a string. If a single shelf is provided for a string, monitor any one of the middle batteries. If more than one shelf of batteries is provided for a string, monitor the middle battery of each shelf. If more than one stand is provided, monitor the middle battery of each shelf on each stand. Decide on which batteries will be used to represent battery temperature and note their numbers in the “Battery Number” column on the “Temperature Measurements on Selected Batteries” portion of the Installation and Maintenance Record. This will ensure that the same batteries will be used for all future measurements. 8. This step is required only if inter-cell connectors are being used in lieu of cable assemblies. Battery module terminals are precoated with NO-OX-ID A® at the time of manufacture. Ordinarily they will not require cleaning and recoating. Clean the contact surface areas of exposed copper post terminals with a dry nonabrasive cloth and recoat only if they appear dirty.

6 - 4 Installation Issue 7 November 1998 9. If the case is dirty when removed from the shipping container, clean the case with a cloth dampened with water before installing it in the battery stand. Battery String Location Environmental Requirements The operating environment must comply with the National Electric Code Article 110, “Requirements for Electrical Installations,” and Article 480-8, “Battery Locations,” and any applicable state and local regulations. The IR-30EC and IR-40EC Series I batteries, like all lead-acid batteries, are affected by the ambient temperature. Maintain a low ambient temperature and/or install a temperature compensation device that adjusts rectifier float voltages in response to high battery temperature. Battery temperatures above 77°F (25°C) decrease battery life while increasing battery capacity. For battery temperatures lower than 77°F (25°C) the capacity will decrease, but battery life will not be adversely affected. Battery temperatures within the same string must be maintained uniformly. When batteries are installed where they will be exposed to heat radiation or direct sunlight, provide shields for the radiators or blinds for the windows to maintain a low battery temperature. In particular, the top row of a multi-tiered stand is apt to have a higher environmental temperature than the bottom. Where necessary, use fans or other means of ventilation to minimize the Caution Use only water to clean batteries. Note Lucent Technologies strongly recommends a temperature compensation device in high-temperature environments. Failure to use such a device may result in high battery temperature that can cause premature battery failure and may reduce or void the warranty.

Issue 7 November 1998 Installation 6 - 5 temperature variation. See Section 8 for procedures to measure battery temperature. Mixing Batteries in a String As batteries age, their characteristics change. As a general practice it is not recommended to mix new batteries with older batteries in a string. A weak battery in a string can cause the entire string to fail prematurely. Mixing Parallel Strings of Batteries As a general practice, it is not recommended to mix strings of VRLA batteries with different capacities. However, this may be acceptable in some situations: Constant Current, Separate Chargers Some battery systems have a dedicated, constant current charger per string. Constant Voltage Chargers It is not recommended to mix “old” strings of batteries with “new” strings of batteries. Battery Installation The following precautions should be taken when installing the IR-30EC and IR-40EC batteries: • IR-30EC and IR-40EC batteries should be installed in an upright position as a precaution against electrolyte leakage. Caution Operating Lucent Technologies IR-30EC and IR-40EC Series I batteries for any significant interval of time outside recommended voltages and/or temperatures will cause reduced performance and premature failure and may reduce or void the warranty. Note To insure maximum battery performance, do not mix Lucent Technologies IR-30EC and IR-40EC Series I batteries with other types of batteries.

6 - 6 Installation Issue 7 November 1998 • Do not install batteries so that the weight of the battery is supported by the lead assembly. Connect the batteries to the associated equipment by the lead assembly that extends from the battery terminals to a connector selected to mate with the associated equipment. Initial Charging To ensure full charge and adequate initial performance, store and maintain batteries according to instructions in Section 5, Battery Storage, and use the guidelines in this section to charge the batteries at the time of installation. The purpose of an initial charge is to compensate for self discharge that occurred in the interval between manufacture and installation. Under normal circumstances, the battery will regain most of its capacity after several hours float charge; 90% capacity should be obtained within 24 hours of float charge. See Table 6-A for detailed initial charging instructions.

Issue 7 November 1998 Installation 6 - 7 Table 6-A: Initial Charging Battery Condition Action All batteries have similar date codes and storage histories and none are more than 6* months old or they have been maintained according to the “Battery Storage” section of this product manual. Make voltage and polarity checks and connect string(s) to plant. Charge at the float voltage of 13.5 ±0.06 volts per battery. The batteries have dissimilar date codes (more than one month apart) and they are within the required recharge period (charge-by date). Using an external charger**, charge the string at 13.98 ±0.06 volts per 12V battery for 24 hours. Continue the charge for another 24 hours at the plant float voltage: 13.5 ±0.06 volts. Make voltage and polarity checks and connect the string(s) to the plant. The batteries are older than 6* months or have not been maintained according to the “Battery Storage” section of this product manual. Do not install. Replace batteries. *If the storage temperature exceeds 90°F (32°C), the open circuit time should not exceed 3 months. ** The charger must have overcurrent protection in its output, must be able to remain across the batteries in case of an ac power failure, and should not have crowbar protection. (Crowbar protection is an option used on some commercial portable power supplies that clamps a short across the output leads of the rectifier when the rectifier senses a higher voltage at the load than it is generating. This feature should not be used with batteries.)

6 - 8 Installation Issue 7 November 1998 Placing a Battery String Into Service Batteries should be in service within 48 hours of initial charge. If a battery is left on open circuit for more than 48 hours after the initial charge, treat it as if it had never received an initial charge. Since battery performance is based on the output at the battery terminals, the shortest electrical connection between the battery system and the operating equipment results in maximum total system performance. When a cable different than the one provided with the battery is used, cable size should be specified and installed that will maintain appropriate voltage drop between the battery system and the operating equipment. Excess voltage drop will reduce the desired reserve time of the battery system. When paralleling valve-regulated batteries, the capacity, arrangement, and external circuit length should be identical for each battery. Wide variations in the battery circuit resistance can result in unbalanced charging (i.e., excess charging current in some batteries and undercharging in others). As a result, cell failures in one battery string and subsequent loss of performance capabilities of that string will result in higher loads in the other parallel string(s), which may exceed the ratings of the battery connections. This can damage the battery and dramatically shorten battery life. Installation Records The “Installation and Maintenance Record” (see Section 10) is required for warranty validation. The installer should use this form to record the following measurements. Voltage Measurements Before connecting parallel strings together or individual strings to the plant bus, make three voltage measurements: 1. Make the first reading across the string to verify that the batteries are connected properly and that the polarity is correct. (The string voltage should equal at least 12.8 volts times the number of batteries.) 2. Make the second measurement across the plant charge and discharge battery buses. The voltage difference between the string and plant should not exceed 0.05 volts unless the plant is at 0 volts because the chargers are turned off. If a larger differential exists, the string should be charged at the plant voltage (or the plant voltage lowered) until the

Issue 7 November 1998 Installation 6 - 9 voltage differential is less than 0.05 volts. (This should prevent arcing during the final connection.) 3. Make the final reading to record voltages of individual batteries. (See “Individual Battery Voltages” in Section 8, Maintenance, for measurement procedure.) Record these in the Installation and Maintenance Record. A DMM (digital multimeter) is suitable for battery voltage readings. The accuracy of an equivalent meter should be 0.05 percent on the dc scale. The meter must be checked periodically for accuracy and calibration. After recording these initial measurements, the installer should turn the Installation and Maintenance Record over to the maintenance organization as part of their permanent records. See Section 8, Maintenance, for maintenance routines and measurements that must be recorded. Caution Exercise extreme caution when making voltage readings to prevent accidental grounding or shorting of leads during measuring operations. Connections at the meter must be secure and free of any possibility of touching or becoming grounded. Never remove connections at the meter end without first disconnecting the test leads from the battery. Remove test lead connections at the battery immediately after each reading is taken.

Issue 7 November 1998 Operation 7 - 1 7 Operation Lead-acid Battery Gassing Rate This section provides general information and guidelines for estimating the hydrogen gassing rates of lead-acid batteries on charge. It is beyond the scope of this document to provide the detailed methods or the engineering design required to maintain safe levels of hydrogen in battery enclosures. All lead-acid batteries generate hydrogen and oxygen gas at the negative and positive plates, respectively. The generation of these gases occurs during all conditions of use, including charge, discharge, and while on open circuit during storage. The rate of gas generation on discharge and open circuit is generally very small but cannot be completely ignored. For this reason, never place lead-acid batteries in an air-tight enclosure. Explosive mixtures of hydrogen in air are present when the hydrogen concentration exceeds four (4) percent by volume. The concentration of oxygen does not significantly change the lower explosive limit of hydrogen in air, and, therefore, only hydrogen will be considered here. If the concentration of hydrogen in air exceeds four (4) percent by volume, there is a risk of explosion if the gas is ignited. Therefore, to provide a margin of safety, lead-acid battery areas must be ventilated to limit the accumulation of hydrogen gas under all anticipated use conditions to a recommended maximum of one (1) percent of the total free volume in the enclosed battery area. In flooded lead-acid batteries, gassing rates approach the theoretical values calculated from the dissociation of water. In valve-regulated, lead-acid batteries (VRLA) the recombination of oxygen gas at the negative electrode results in reduced oxygen and hydrogen evolution from the battery. Generally, VRLA batteries evolve from less than 1% to 20% of the hydrogen

7 - 2 Operation Issue 7 November 1998 produced by flooded lead-acid batteries under similar charging currents, and are designed to achieve greater than 95% recombination efficiency at normal float charge and temperature. However, charging at voltages greater than the nominal float voltage, charging at elevated temperatures, shorted cell(s), and a number of other possible conditions may result in significantly greater charging current and hydrogen gassing. It is important to note that the hydrogen gassing rate at 0% recombination, the worst case condition, is the same for both flooded and valve-regulated technologies at equivalent charging currents and temperatures. From electrochemical theory, if all the charging current is used to generate gas, each cell will generate 0.016 cubic feet of hydrogen per hour, per ampere of charging current at 77°F (25°C) and one atmosphere pressure. For example, a 48V string of lead-acid batteries requiring 1 ampere of float current at 77°F can produce as much as 0.4 cubic feet of hydrogen per hour (0.016ft3/hr x 1 ampere x 24 cells), or as little as 0.004 cubic feet per hour at 99% recombination efficiency, a factor of 100 difference. The quantity of fresh air required to maintain an explosion-safe environment in the battery area (enclosure) will vary greatly depending on many factors including, but not limited to, the age and condition of the battery, the number of cells in the battery area, the battery temperature, and the current flowing through the batteries. Therefore, the design of a ventilation system for batteries in a specific application requires careful consideration of factors other than the gassing rate of new batteries in typical operation. Typical gassing rates may be useful as a “best case” condition, but cannot adequately address “worst case” or any other operating condition that may occur during the service life of the battery. Service Life Since battery temperature exceeding 77°F (25°C) will decrease expected life by approximately 50% for each 18°F (10°C) increase in average temperature, it is important to consider the temperature of the battery environment when designing equipment or determining battery life expectancy.

Issue 7 November 1998 Operation 7 - 3 Charging Lucent Technologies IR-30EC and IR-40EC batteries may be charged either by constant potential or constant current chargers. A potential of 13.38-13.62 ±0.06 volts per 12V battery is recommended for constant voltage charging at 77°F (25°C). When batteries are used in plants with a constant current charger, such as Lucent Technologies 337A1, a constant current that results in 13.38-14.4 volts per 12V battery 77°F (25°C) is recommended for float-standby applications. Battery String Float Voltage It is extremely important to maintain the battery at the proper float voltage for constant voltage application. The recommended float voltage per battery is 13.5 ±0.06 volts at a battery temperature of 77°F (25°C). To determine the battery string float voltage, use the following equation: Battery String Voltage = recommended float voltage per battery x number of batteries For example, a 4-battery string of IR-30EC or IR-40EC batteries should be floated at: Battery String Voltage = 13.5 volts x 4 batteries = 54.00 volts Charging Voltage Ripple The amount of ac voltage ripple present on the charging voltage for the battery can seriously affect battery performance. Excessive ripple could result in sharply reduced battery life and Caution For constant voltage application, failure to reduce the float voltages in systems without temperature compensation may result in premature failure or thermal run-away. Caution Operating Lucent Technologies IR-30EC and IR-40EC batteries for any significant interval of time outside recommended temperatures will result in reduced performance and premature failure and may void the warranty.

7 - 4 Operation Issue 7 November 1998 increased gassing rates. Refer to “Lead-acid Battery Gassing Rate.” Both the amplitude and frequency of the ripple affect the degree of battery degradation. As a guideline, the charging voltage ripple for the IR-30EC and IR-40EC batteries should not exceed 60mV peak to peak per 12V battery or last longer in duration than 8mSec. Battery and Ambient Temperatures Ambient temperature can affect the capacity and life of the IR-30EC and IR-40EC batteries. The temperature that has the most direct effect is the battery’s internal temperature. All valve-regulated lead-acid batteries use oxygen recombination technology, which generates more heat than conventional flooded batteries. As a result, the battery temperature is often higher than the ambient temperature. The Warranty Period outlined in Section 12 is based on the battery temperature, not the ambient temperature. Maintain a low battery temperature by adjusting the ambient environment temperature and/or air ventilation. Elevated battery temperatures (greater than 25°C or 77°F) decrease battery life while increasing battery capacity (see Section 6, “Environmental Requirements”). Low temperatures do not affect battery life; however, capacity decreases with decreasing temperatures. Applications should allow for battery temperatures within the same string to be at a uniform temperature. Since hot air rises, the top row of a multi-tiered stand configuration is likely to have higher temperatures than the Caution AC charging ripple greater in magnitude than 60mV peak to peak per battery or longer in duration than 8mSec should not be used without prior consent of Lucent Technologies Power Systems; failure to comply can void the warranty. Caution Operating Lucent Technologies IR-30EC and IR-40EC batteries for any length of time outside the recommended voltages and/or temperatures will cause reduced performance and premature failure and reduce or void the warranty.

Issue 7 November 1998 Operation 7 - 5 bottom row. When necessary, use fans or other means of ventilation to minimize temperature variations between modules in the same string. Capacity The capacity of a battery is expressed as a percent of its rated value. For example, if a battery is discharged at the 5-hour rate and it lasts 5.25 hours before reaching 10.5 volts, it is said to have 105% of its rated capacity. Discharge Capacity Test This test is not required as a routine maintenance procedure. However, a discharge test is the best way to determine if sufficient reserve power is available. The discharge capacity test should be run directly off float charge without prior boost charge. Battery strings to be tested should be on float for at least one month without a boost charge or power failure exceeding 30 minutes. Caution Lucent Technologies strongly recommends a temperature compensation device in high-temperature environments. Failure to use such a device may result in high battery temperature that can cause premature battery failure and reduce or void the warranty. Figure 7-1: Temperature Versus Battery Capacity (within 5%) for IR-30EC/40EC Percent of Available Capacity Battery Capacity vs. Temperature 110 100 90 80 70 60 50 Temperature (°F) 10 20 30 40 50 60 70 80 90 100 110 120 130 C Rate 8

7 - 6 Operation Issue 7 November 1998 There are several different methods that can be used in testing the capacity of the string. In general, the more definitive the test, the longer and more difficult it is to perform. For example, measuring individual battery voltages after 15 minutes on a plant load discharge will highlight batteries with only 25% capacity. However, it usually requires a 5-hour, off-line discharge test to spot a 5% fading in capacity. If it is determined that a discharge test should be part of the maintenance program, try to carry out the test consistently from site to site and interval to interval. In this way, comparisons and trends can be easily noted. In selecting a test, the choices are as follows: • single battery or string • partial or full discharge • constant or variable load The easiest test to run is to shut off the ac power and let the plant load discharge the batteries until 20% to 50% of the capacity has been removed. The disadvantage of this type of test is that the current may not be constant throughout the discharge, from interval to interval, or from site to site. This disadvantage can be overcome by adding an external load to the bus. This load can be adjusted throughout the discharge to maintain a constant current. In light of the above, a one-hour discharge similar to the plant load of a single battery string off-line is the preferred routine maintenance test. The one-hour discharge rate to 11.4 volts is a reasonable value since it will leave approximately 60% reserve at a lower rate. A single-string, off-line, five-hour rate to 10.5 volt discharge test should only be done on those rare occasions where a very accurate appraisal of the capacity is required. It is not suggested to be used on a routine basis. To carry out a discharge test properly, measure and record the time, current, battery voltages, and initial battery temperature. The thermometer should be accurate to within 2°F (1°C) to achieve reasonable accuracy. The current and the time should be measured to an accuracy of 3% and the module voltage measured to the nearest millivolt. Recharge After Discharge Recharge at the normal float voltage of 13.5 volts per cell/battery. The recharge should begin as soon as possible after the discharge.

Issue 7 November 1998 Operation 7 - 7 Boost Charge Boost charging the IR-30EC and IR-40EC batteries is not recommended without the concurrence of Lucent Technologies. Call 1-800-225-7822 for technical assistance. During a boost charge, water loss due to electrolysis is greatly increased. In valve-regulated, lead-acid cells, frequent or prolonged boost charges can result in premature failure caused by cell dry-out. Boost charging at elevated battery temperatures can be especially detrimental to the batteries.

Issue 7 November 1998 Maintenance 8 - 1 8 Maintenance Maintenance Schedule Proper maintenance ensures good performance, provides an opportunity to view trends as they develop, and ensures that the product remains under warranty coverage. Table 8-A lists the required routines and intervals for maintaining the IR-30EC and IR-40EC batteries. “Paragraph Reference” refers to the procedures for performing the routines that follow the table. (The procedures and intervals are the same for all models of the IR-30EC and IR-40EC batteries.) Table 8-A: Required Maintenance Routines Routine Action Interval Paragraph Reference Individual Battery Voltages Measure/Record Quarterly “Individual Battery Voltages” Battery Temperature Measure/Record Quarterly “Measuring Battery Temperatures” String Current Measurement Measure/Record Quarterly “String Current Measurement” Inter-module Connections of Module and Rack Inspect Quarterly “Inspection and Cleaning” Clean As needed “Inspection and Cleaning” Retorque* As needed “Retorquing Inter-battery Connections” *This procedure is required only if inter-cell connectors are being used in lieu of cable assemblies. Note: Failure to adhere to these maintenance schedules and to record results will void the warranty.

8 - 2 Maintenance Issue 7 November 1998 Maintenance Routines When performing any maintenance activities, it is essential to follow all safety procedures outlined in Section 4. Section 10, Installation and Maintenance Record, contains a form for recording the measurable parameters noted in Table 8-A. The maintenance person taking these measurements should include the date on which measurements were taken as well as their initials. This information will aid in establishing trends that can be used to determine overall health of the batteries. The completed forms will be used for any future warranty claims. Individual Battery Voltages Using a calibrated digital voltmeter with at least two-digit accuracy, measure the voltage across each battery terminal to ensure they are floating properly. Record the data in the space provided on the “Voltage Measurements on Individual Batteries” portion of the Installation and Maintenance Record. When making voltage measurements, please note the following: • Readings for each battery must be within ±0.18 volts of the string average (the string average is calculated by dividing the string voltage by the number of batteries in the string). • Any fully-charged battery that reads less than 13.0 volts on float must be replaced. Warning An explosion could occur when sparks are created near the battery string. Use insulated tools and discharge all static electricity from your body before performing any work. Caution Exercise extreme caution when making voltage readings to prevent accidental grounding or shorting of leads during measuring operations. Connections at the meter must be secure and free of any possibility of touching or becoming grounded. Never remove connections at the meter end without first disconnecting the test leads from the battery. Remove test lead connections at the battery immediately after each reading is taken. Review the safety precautions in Section 4.

Issue 7 November 1998 Maintenance 8 - 3 • Because float readings are affected by discharges and recharges, these readings must be taken when the batteries have been on continuous, uninterrupted float for at least one month. Measuring Battery Temperatures Make temperature measurements using calibrated equipment, such as an infrared-based or thermocouple-based measuring device. Make all measurements on the negative terminal of the selected batteries. If using a thermocouple device, place the sensor on the negative terminal of the battery and wait a few seconds for the meter to stabilize. Note the measured value in the appropriate column on the “Temperature Measurement on Selected Batteries” portion of the Installation and Maintenance Record. String Current Measurement Use a calibrated DMM and current probe placed around a string cable to make individual battery string current measurements. Note the measured value in the appropriate column in the “String Float Current Measurements” portion of the Installation and Maintenance Record. Inspection and Cleaning A visual inspection of the battery plant should be done on a quarterly basis. If necessary, the battery modules and racks can be cleaned using a soft cloth dampened in water. The inter-battery connections should be inspected for corrosion. Report any sign of acid or corrosion to Lucent Technologies. Retorquing Inter-battery Connections This procedure is required only if inter-cell connectors are being used in lieu of cable assemblies. Ensure that all battery connections are tight. If required, retorque these connections to 40 ±10 inch-pounds, using an insulated 5/16-inch socket and torque wrench. Flame Arrestor Vent Feature The vent and flame arrestor are maintenance free and do not require attention under normal circumstances. However, do Caution Over-tightening of the inter-module connectors could strip the bolt and/or nut threads, resulting in loose connections.

8 - 4 Maintenance Issue 7 November 1998 NOT allow gas vents to become clogged or excessive internal pressure may result. Battery Replacement As batteries age, their characteristics change. As a general practice it is not recommended to mix new batteries with older batteries in a string. A weak battery in a string can cause the entire string to fail prematurely. Should it become necessary to replace one or more batteries in a battery string, the replacement battery(ies) must be charged according to Table 6-A. Do not exceed the time on charge. Following the initial charge, keep the battery(ies) on continuous float until the replacement can be made. The time between discontinuing the float charge and the completion of replacement should not exceed 24 hours. Note To insure maximum battery performance, do not mix Lucent Technologies IR-30EC and IR-40EC Series I batteries with other types of batteries. Caution Make sure the batteries are at equal float charge before connecting them into a string.

Issue 7 November 1998 Discharge and Power Data 9 - 1 9 Discharge and Power Data Discharge Capacity The discharge capacity of Lucent Technologies IR-30EC and IR-40EC batteries is directly related to temperature and inversely related to the discharge rate. The maximum recommended discharge rate is the 1-hour rate. Discharge Cycle Life Discharge rate, recharge parameters, and depth of discharge all contribute to discharge cycle life. The most important factor in determining discharge cycle life for Lucent Technologies IR-30EC and IR-40EC and most other lead-acid battery designs is generally the depth of discharge (capacity removed/capacity available). The more completely a battery is discharged, the lower the number of cycles available prior to failure, which is defined as 80% of rated capacity. Lucent Technologies IR-30EC and IR-40EC battery applications have been optimized to deliver high capacity per unit volume in predominately float-standby applications where deep, long duration discharges are relatively infrequent. Therefore, the number of discharge cycles that may occur throughout the battery's life is not considered to be a significant factor in battery failure. It is not recommended for applications that require deep and/or frequent cycling. Caution Discharge of batteries below 1.75V per cell may result in recharge abnormalities and premature failure.
