Battery Charging (Sealed Battery)
The single most important thing about maintaining a sealed battery is to
keep it fully charged. Since the battery is sealed and the sealing strip
cannot be removed, you must use a voltmeter or multimeter to measure
DC voltage.
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.
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. When using an automatic charger, refer to the charger manufac-
turer's instructions for recharging. When using a constant current
charger, use the guidelines on the next page for recharging.
Always verify battery condition before and 1-2 hours after the end of
charging.
