Battery Charging (Sealed Battery)
The following battery charging instructions apply only to the
installation of a sealed battery. Read all instructions before proceeding
with the installation of this battery.
The sealed battery is already filled with electrolyte and has been sealed
and fully charged at the factory. Never pry the sealing strip off or add
any other fluid to this 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 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.
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.
