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 the battery voltage is 12.8 or greater.
Tip: 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 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.
Tip: Always verify battery condition before and 1-2 hours after the end of charg-
ing.
