MAINTENANCE
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. 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 12.6 V or higher.
2. If the voltage is less than 12.6 volts, recharge the battery at 1.2 amps or less
until battery voltage is 12.6 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
following guidelines via the table below.
