MAINTENANCE
BATTERY INSTALLATION
Using a new battery that has not been fully charged can damage the battery and
result in a shorter life. It can also hinder vehicle performance. Follow the steps in
the Battery Charging section before installing the battery.
1. Ensure that the battery is fully charged.
2. Place the battery in the battery holder.
3. Coat the terminals with dielectric grease or petroleum jelly.
4. Connect and tighten the red (positive) cable first.
5. Connect and tighten the black (negative) cable last.
6. Verify that cables are properly routed.
SEALED/AGM BATTERY MAINTENANCE AND
CHARGING
An overheated battery may explode, causing severe injury or death. Always
watch charging times carefully. Stop charging if the battery becomes very
warm to the touch. Allow it to cool before resuming charging.
Sealed batteries are already filled with electrolyte and have been sealed and
fully charged at the factory.
Never pry the sealing strip off or add any other fluid to a sealed battery.
BATTERY CHARGING
For a refresh charge, follow all instructions carefully.
1. Check the battery voltage with a voltmeter or multimeter. A fully charged
battery will register 12.8 V or higher.
2. If the voltage is less than 12.8 volts, recharge the battery at 1.2 amps or less
until battery voltage is 12.8 or greater.
3. If the voltage falls below 12.5V, charge it immediately, or the battery runs the
risk of sulfation and reduced battery life.
The single most important thing about maintaining a sealed battery is to keep it
fully charged.
