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 at 1.2 amps
or less until battery voltage is 12.8 or greater.
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.
NOTE: Always verify battery condition before and 1-2 hours after the end of
charging.
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.
