The battery is maintenance free. If the battery ever requires 

charging, use only a voltage regulated taper current charger 

designed specifically for sealed lead acid gel cell batteries 

rated at 2 amps or less (part # 505583501). A standard auto-

motive, or any other type, battery charger not designed specifi-

cally for sealed gel batteries will cause permanent damage to 

the installed battery and void any warranty. Do not leave the 

ignition key in the “ON” position as this will drain the battery.
