Battery Charging (Sealed Battery)
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.
NOTE: When using an automatic charger, refer to the charger
manufacturer's instructions for recharging. When using a
constant current charger, use the following guidelines for
recharging.
WARNING
An overheated battery could 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.
NOTE: Always verify battery condition before and 1-2 hours after the
end of charging.
