In the event it is wired to recharge a larger than recommended battery, charger will stop charging after maximum stage recommended time and the RED LED will be FLASH slowly. At this point, Battery must be disconnected. 。REVERSE POLARITY: Charger has reverse battery protection. (Red LED ON, while output leads are connected backwards), Disconnect and correct connection to battery. 。SHORT CIRCUIT PROTECTION: Charger will turn off upon detecting a short circuit (Red LED ON.

。Output lead: 6 feet SPT-1 2X18AWG with insulated battery clamps. ENVIRONMENTALCHARACTERISTICS: 。Operating temperature range: 32 to 104° F 。Storage temperature range: 10 to 170°F 。Operating humidity range: 90% RH Max ECO MODE: If AC power is connected, and the battery is not connected, the charger will automatically go into ECO mode. Input power draw in ECO mode is less than 1.5W (0.04kWh per day). Power consumption in maintenance mode is 0.05kWh per day. CHARGING INSTRUCTIONS: STEP 1 - Pre Charge: Battery & Electrolyte Level Check 。Check the battery electrolyte level (Only for Flooded or WET battery). If necessary, remove the vent caps and add distilled water so the levels are halfway between the upper and lower fill lines. 。 STEP 2 - Connect Charger to Battery 。If the battery is out of the vehicle: 。Connect the Red lead from the charger to the positive (+) battery terminal. 。Connect the Black lead from the charger to the negative (-) battery terminal. 。If battery is still in the vehicle, determine if the vehicle is positively or negatively earthed. 。If Negatively earthed (Most Common) – First connect the Red (+) battery charger lead to the Positive (+) battery post and then connect the Black (-) battery charger lead to the vehicle’s chassis and away from the fuel line. 。If Positively earthed – First connect the Black (-) battery charger lead to the Negative (-) battery post and then connect the Red (+) battery charger lead to the Vehicle’s chassis and far away from the fuel line. STEP 3 – Connect Charger to Power (115Vac / 230Vac) 。Connect the battery charger to AC mains powered socket. 。The Charger will automatically start when AC power is connected and switched on. (Note: If the Fault Indicator LED illuminates Red, please check your connections as it’s likely that the Positive and Negative leads are reversed. Refer to Trouble Shooting page for further information)

。 If the battery is out of the vehicle: 。Switch OFF and remove the AC power socket from the outlet. 。Remove the black lead and then the red lead. 。Check electrolyte levels if possible. (As they may need topping up with distilled water after charging) 。If the battery is in the vehicle: 。Switch OFF and remove the AC power socket from the outlet. 。Remove the lead from the vehicle chassis. 。Remove the lead from the battery. 。Check electrolyte levels if possible. (As they may need topping up with distilled water after charging) THECHARGING PROCESS: The charging stages and performance are as follows: Battery initial condition check After all connections are made, the charger will automatically diagnose battery condition. If battery voltage is above 9V, charger will go into soft start stage. Otherwise, charger will go into desulphation mode. If the battery voltage does not exceed 9V after 6 hours of rejuvenation, you will need to disconnect the battery and check its condition, voltage rating or if it is connected to a load while charging. Smart Charging Stages 。Desulphation: 。20% charging LED: ON. 。Engage high peak pulse for deep-discharge or sulphated battery 。dissolve the lead sulphated crystal bring the electrolyte fluid to well-distributed state 。The battery voltage will increase slowly. 。Soft start: 。20% charging LED: ON. 。The battery voltage will increase slowly. 。Bulk : 。80% charging LED: ON. 。The battery can be charged about 80%. 。The charger delivers an almost constant current 2000mA until the battery voltage reaches the set value. 。Absorption : 。80% charging LED: ON. 。The battery can charge up to almost 95%. 。The charging current tapers and the charging voltage are kept constant at the set value. 。Test Mode 。The charging is interrupted for a short period while battery voltage is measured. 。If the battery voltage falls too quickly, the battery could be faulty.

。Recondition charging 。Charger will go into this stage if battery fails Test Mode due to its condition, age or being under charged. 。This stage can recover batteries from deeply discharged state increasing performance and battery life. 。FULL LED: Flashing. 。Float mode 。Full LED: ON. 。The float mode allows the charger to effectively be left connected to your batteries; it works at a safe level and ready for use. 。Maintenance mode 。Full LED: ON. 。The program engages a special charging waveform and monitors the battery voltage variety, if the battery voltage sinks, the special pulses will keep the battery in optimal state, if the battery voltage drops even lower, the battery charger will switch into bulk charging . The maintenance mode allows the charger to be connected to the battery over the course of a season; If possible, check the electrolyte liquid level in the battery. LEDstatusindicationtable:
