Battery Charging
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.
A sealed battery must always be maintained with a full charge. 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. The battery should be disconnected from a load or charger for at
least two hours before checking voltage. 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
manufacturer's instructions for recharging. When using a constant
current charger, use the guidelines on the next page for recharging.
