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.
Do not ever 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.
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 the battery voltage is 12.8 or greater.
Tip:
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.
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.
Tip:
Always verify battery condition before and 1-2 hours after the end of
charging.
