Battery Charging (Sealed Battery)
The following battery charging instructions apply only to the installa-
tion 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 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. 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.
2. 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.
