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.
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.
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 manufacturer's
instructions for recharging. When using a constant current charger, use the
guidelines below for recharging.
Always verify battery condition before and 1-2 hours after the end of charging.
