Wear safety glasses. Special care must be taken when installing a battery to avoid a
serious explosion or accident.
If available, a computer memory saver should be used to save the vehicle's memory and avoid having to reprogram. Follow the manufacturer's directions carefully to avoid damageto the computer and/or electrical system.
1.Mark the positive (paS) cable. Turn off all electrical accessories. Disconnect hood and trunk bulb if opened to cut off all current.
2.Carefully remove old battery, disconnecting the ground cable first, to avoid any dangerous sparking around the battery.
3.Battery tray should be thoroughly cleaned and inspected for defects. Use a paste made from baking soda and water to neutralize any acid or corrosion. Repaint if necessary. It should be held fast to supporting members to prevent vibration and road shock. Replace tray if necessary.
4.The battery should rest level in the tray. Be sure terminals will clear hood, fender, etc.
5.The hold-down must be tightened until it is snug. Do not overtighten. Too much pressure on the battery case will cause damage to it internally and externally ... causing an acid leak.
6.Cable terminals should be brushed until shiny and spread wide so that they will slip over the battery post without force. Do not hammer on them. Be sure marked pas cable is connected to pas (+) terminal. Connect NEG (-) cable last to prevent dangerous sparks. DO NOT OVERTIGHTEN/ It's a good idea to installspecial corrosion retarding fiberwashers around terminals to help extend battery life.
7.Side terminal batteries need special care. Overtightening the terminal bolts will severely damage the battery and could cause a dangerous explosion. Use aspecial side terminal torque tool to avoid this hazard.
8.Coat the terminals and exposed metal parts around the battery with a goodquality protective spray.
Shield eyes and face from batteries at all times! Be sure vent caps are tightand level. Place damp cloth over vent caps on both batteries. Be sure vehicles or cable ends do not touch. Use a good quality booster cable set.
BE CAREFUL !!
WARNING: Batteries produce explosive gases. Keep sparks, flames and cigarettes away from batteries at all times.
Protectyour eyes at all times. Never lean over battery when jump starting orperforming other maintenance. Remember .•• always wear safety glasses whenworking around batteries!
The first step to routinely servicing a battery is to make a visual inspection. Look for defective cables, loose connectors, corrosion, cracked cases or covers, loosehold-downs, and deformed or loose terminal posts. Remember. .. always
wear safety glasses.
Remove and replace a battery at once if there are cracks in cover or case. Place the leaking battery in a plastic bag and take it to a battery seller for proper recycling. ,
To remove corrosion and dirt from terminal posts, hold downs, tray or hold-down parts,scrape or brush it off. Use a corrosion removing spray or immerse the part in an alkaline solution such as baking soda in the proportions of one pound to a gallon of water. The corrosion is neutralized when the solution stops bubbling.Wash the part with water, dry, replace and apply a prepared corrosion protection spray.
Leave vent caps in place while charging to avoid explosion.
Batteries should be charged if hydrometer reading is below 1.225 SG, or 12.4 open circuit voltage, or the load test is below 9.6 volts.
Do not leave a battery on charge for more than 48 hours.
Stop the charge when two hydrometer or voltage readings recorded two hours apart indicate no increase.Further charging would be useless and may damage the battery and shorten its life.
If the battery won't come up to full charge, replace it.
If violent gassing or spewing ofelectrolyte occurs, or the battery case feels hot, reduce or temporarily haltcharging to avoid damaging the battery.
NEVER attempt to charge a frozen battery! Allow it to warm to 60°F (15.5°C) beforeplacing on charge. Otherwise a dangerous explosion can occur.
NEVER leave abattery on a trickle charger longer than 48 hours. Otherwise, serious damagewill occur.
ALWAYS leave vent caps in place to avoid explosion.
The voltage regulator should be checked every 10,000 miles or every time you change oil. It should be checked immediately if the battery is hot to the touch, if electrolyte is bubbling or spewing from the vents, if your hydrometer reading is below 1.225 or above 1.300, or if the open circuit voltage is below 12.4 volts or above12.9 volts. Overcharging is evident by excessive water consumption and/or spewing or bubbling of electrolyte out ofthe vents. Undercharging is 'evidentby slow cranking or lights dimming at idle.
There are two styles ofbattery ... non-accessible maintenance-free types and accessible maintainable types with removable vent caps.
Before adding water to amaintainable battery, take an open circuit voltage reading and/or hydrometer reading of one cell. Use a differentcell each time. If the readings are above 75%, the battery isfine. If the readings are below 75%, charge the battery. If the electrolyte level is too low to read with a hydrometer, addwater and take the hydrometer reading the following day, after the vehicle has been driven and the water has had an opportunity to mix. Check electrolyte levels in all cells. If necessary, add only clear, odorless drinkingwater to bring the liquid level to the level indicator or to 1/2" (13mm) above the top of the separators. Distilled water is preferred, especially if the water in your area has high iron. Do not overfill any cells. Excess electrolyte may be forced from an overfilled cell and cause corrosion on adjacent metalparts, reduce performance, and shorten life. In cold weather, do not fill cells with water and let stand without running engine or driving the vehicle long enough to allow water to mix with acid. Otherwise, freezing might occur and thebattery may crack or explode.
Maintenance-free,non-accessible batteries are designed to eliminate the need to add water. Yet the volume of electrolyte above plates may eventually become depleted due to abnormal conditions such as high heat or improper regulator setting. Use a voltmeter to check the state of charge.
See chart under"CHARGING TIPS" to determine if charging is necessary. DO NOT OPEN FLUSH COVER BATTERIES! If opened, serious personal injury can result and warranty will be voided.
Always Load Test
Follow-up your hydrometer or open circuit voltage test with an adjustable load test to determine if the battery has adequate electrical performance. Follow the instructions on the tester or ask your favorite service facility to load test your battery. If the battery maintains a minimum "on load" voltage of 9.6 volts for 30 seconds, it is in good condition. If not, recharge and load test again. If it fails a second time, REPLACE THE BATTERY IMMEDIATELY. Remember to keep sparks and flames away. ALWAYS
WEAR EYE PROTECTlON when working around batteries.
Always select a battery that has enough cranking power and reserve capacity to get the job done. Consider the vehicle manufacturer's recommended capacity to be aminimum capacity guideline.
Along with electrical accessories, temperature also has a dramatic effect on battery performance. Vehicles that are operated in extremely cold climates will need a battery
that's rated well above the minimum a.E. recommendation. Remember, you can't select a battery with too much power!
Temperaturehas a dramatic effect on a battery's ability to crank an engine. Not only does cold rob batteries of power, it also stiffens motor oil, making engines harderto start. And heat can damage batteries by causing internal components to wearout quickly while also making engines difficult to start. So do yourself afavor, select the higher capacity, more powerful batteries you'll need totackle demanding climate.
