Napa LEGEND 75 Battery Charging Manual

WARNING: Follow all safety instructions when handling batteries! Always wear safety glasses and a face shield when working on or near batteries. Safety Comes First: Before starting any of the following procedures, read and follow all safety information. Read Instruction Manual before proceeding. All batteries generate explosive hydrogen gas. Keep sparks, flames and cigarettes away from batteries at all times. Do not connect or disconnect “live” circuits. To avoid creating sparks, always turn charging and testing equipment off before attaching or removing clamps. ALWAYS DISCONNECT GROUNDED CABLE FIRST AND CONNECT IT LAST TO PREVENT DANGEROUS SPARKS. Perform all work in a well ventilated area. Never lean directly over a battery while boosting, testing or charging it. PROTECT YOUR EYES! Batteries contain corrosive sulfuric acid that can destroy clothing and burn the skin. Neutralize acid spills with a paste made of baking soda and water or large quantities of water. BE CAREFUL!

must be followed in their entirety and in their specified order! VISUAL CHECK: A. Visual inspection. An external inspection of the battery may reveal signs of the cause of failure. 1. Do the terminals show signs of having been hammered, twisted, or driven down into the cover? Do side terminals show signs of over-torquing? Over-torquing can cause internal damage that can't be seen. 2. Does the container or cover show signs of stress, damage, or high temperature? Does the container or cover have worn areas indicating vibration damage? 3. Are the ends of the battery pushed out? This can indicate plate growth. B. Inspect terminals. (Look for: corrosion, loose or broken posts or moisture and dirt around terminals.) C. Inspect for cracks in the case. D. If the battery has a hole in the case or a post is broken, it is not a warranty battery. E. Inspect for loose hold-downs (If battery is in vehicle only) IF ANY OF THESE ITEMS APPEAR, IT IS NOT A WARRANTY BATTERY AND CREDIT WILL NOT BE ISSUED. S T E P 1

Use a post brush to clean battery posts. Neutralize any corrosion with a baking soda/water paste or battery cleaner spray. Scrape or brush off the residue and wash the area with clean water. B. Make sure adapter and tester clamp CONNECTIONS ARE TIGHT. NOTE: All SIDE TERMINAL POSTS must use a proper Side Terminal Charging Post to ensure the best testing and charging results. THREADED STUD TERMINALS must use a proper Group 31 Charging Posts to ensure the best testing and charging results. DO NOT USE Battery Bolt Extenders or Battery Bolts for testing or charging batteries. This will cause the tester to give an inaccurate reading. DO NOT USE Stainless Steel Nuts or the Threaded Stud for testing or charging batteries. This will cause the tester to give an inaccurate reading.

TESTING THE BATTERY: A. Connect tester by hooking up red clamp to battery’s positive post. Hook up black clamp to battery’s negative post. B. Enter the required testing information based on tester being used. C. If the tester indicates "Charge & Re-Test" battery proceed to Step 4. NOTE: If battery needs charging, it is NOT a warranty battery. If the tester indicates "Replace" or "Bad Cell" battery, this is a warrantable battery. Follow the proper warranty procedures. If the tester indicates a "Good" battery proceed to Step 5. NOTE: CONTACT YOUR ESG OR TOOL EQUIPMENT REPRESENTATIVE FOR PROPER EQUIPMENT GUIDANCE TO TEST AND CHARGE BATTERIES. 5

C. After charging has been completed, retest battery on tester (See Step 3). D. If the tester again displays "Charge & Re-Test", warrant battery, following proper warranty procedures. If tester displays "Bad Cell" or "Replace Battery", warrant battery following proper warranty procedures. If tester displays "Good Battery", proceed to step 5. Voltage State Approx.
