.SAFETY PRECAUTIONS.California Proposition 65 Warning: Battery posts, terminals and related accessories contain lead and lead compounds, and other chemicals known to the state of California to causecancer, birth defects and reproductive harm. Wash hands after handling!Warning: Follow all safety instructions when handling batteries! Always wear safety glasses and a face shield whenworking on or near batteries.All batteries generate explosive hydrogen gas. Keep sparks, flames and cigarettes away from batteries at all times. Do notconnect or disconnect “live” circuits. To avoid creatingsparks, always turn charging and testing equipment off beforeattaching 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 directlyover 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 pastemade of baking soda and water or large quantities of water. BE CAREFUL!.IN-VEHICLE SERVICE AND TESTING.Follow safety precautions:WEAR PROPER EYE PROTECTION!Prior to any testing, visually inspect the battery. Look for:• Cracked or broken case or cover • Loose cable connections • Leaking case-to-cover seal • Corrosion • Damaged or leaking terminalsNeutralize any corrosion with a baking soda/water paste or battery cleaner spray. Scrape or brush off the residue andwash the area with clean water. Following your visualinspection, check the battery’s state of charge with a volt-meter.You must boost charge a weak battery before load testing. (See charging chart under “Charging Tips” section.) If fully charged, perform a load test. PROTECT YOUR EYES!Basic Rules for Battery Care & MaintenanceALWAYS WEAR EYE PROTECTION WHEN WORKING AROUND BATTERIES!.DRY CHARGE ACTIVATION.Important…WEAR PROPER EYE PROTECTION!❶ Fill each cell to proper level with battery-grade sulfuric acid of 1.265 specific gravity. Battery and acid must be at a temperature of 60°F to 100°F (16°C to 38°C) at time of filling.❷ Boost charge 12V batteries at 15 amps until specific gravityis 1.250 or higher and the electrolyte temperature is at least60°F (15.5°C). BOTH CONDITIONS MUST BE MET. (Boost charge 6V and 12V heavy-duty batteries at 30 amps.) If violent gassing or spewing occurs, reduce charge rate.❸ After charging, check electrolyte levels. If required, add additional electrolyte to bring all levels to the bottom of the vent wells. DO NOT OVERFILL. If the battery requires top-off while in service, add distilled water…DO NOT ADDACID. .SAFE INSTALLATION.Follow safety precautions:WEAR PROPER EYE PROTECTION!❶ Before removing old battery, mark the positive (+) and negative (–) cables for proper connection to the new battery.❷ Always disconnect the ground cable first [usually negative (–)] to avoid any sparking around battery. Then disconnect the positive (+) cable and carefully remove the old battery.❸ Clean and inspect. If necessary, repaint or replace the tray, hold-down and/or battery cables. Cable ends must be clean and corrosion free. Cable must not be frayed or bare.❹ Put corrosion protection washers on battery terminals. Install new battery in same position as old one and tighten hold-down. Be sure terminals will clear hood, fender, box lid, etc. to avoid vehicle damage and/or explosion.❺ Connect positive (+) cable first. Connect ground cable last. If side terminal connection, use a special side terminal torque tool to tighten side terminal cables to avoid damage. Never overtighten or hammer cables onto terminals.❻ Coat terminals and cable connection with a corrosion protection spray..CHECK THE CHARGING SYSTEM.The voltage regulator should be checked every 10,000 miles or every time you change oil. It should be checked immediate-ly if the battery is hot to the touch, if electrolyte is bubbling orspewing from the vents, if your hydrometer reading is below1.225 or above 1.300, or if the open circuit voltage is below12.4 volts or above 12.9 volts. Overcharging is evident byexcessive water consumption and/or spewing or bubbling ofelectrolyte out of the vents. Undercharging is evident by slowcranking or lights dimming at idle.DANGER/POISON!KEEP OUT OF THE REACH OF CHILDREN.DO NOT TIP.

A load test is the best way to determine if the battery is delivering adequate electrical performance. Makesure your variable load tester is working properly.❶ You can't load test a discharged battery. If the voltage is below 12.4, be sure to completely charge it before continuing. Refer to the charging chart under “Charging Tips” section for important information.❷ To avoid sparking and explosive gasses, be sure load tester is OFF and battery is disconnected before hook-up. Use computer memory saver to retain the vehicle’s electronic memory while the battery is disconnected.❸ Connect the positive (+) tester clamp to the positive (+) battery terminal. Then connect the negative (–) tester clamp to the negative (–) battery terminal. Always protect your eyes.❹ Set the tester for one-half the battery‘s 0˚F cold crank rating and apply the load for 15 seconds. (If the CCA rating is unknown, use 1/2 of the minimum O.E. battery CCA requirement of the vehicle.)❺ Estimate the internal temperature of the battery to the nearest 10˚F. Apply the load for 15 seconds. Note the voltage at 15 seconds with the load on and immediately shut the load off. A reading at least equal to the value from the chart below indicates a good battery.BATTERY TEMP. 12-VOLT BATTERY 6-VOLT BATTERY70°F (21°C) or above 9.60 4.8060°F (16°C) 9.50 4.7550°F (10°C) 9.40 4.7040°F (4°C) 9.30 4.6530°F (-1°C) 9.10 4.5520°F (-6°C) 8.90 4.4510°F (-12°C) 8.70 4.350°F (-18°C) 8.50 4.25❻ If the battery did not meet the required voltage and if it was not charged in Step 1, completely recharge the battery and repeat the test. If it still fails to meet requirements, replace the battery..CONDUCTANCE TESTING.Follow safety
