Battery
The battery is maintenance free. If the battery ever requires
charging, use only a voltage regulated taper current charger
designed specically 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 speci-
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.
WARNING
- Connecting and disconnecting a battery can cause
sparks and short circuits. Do not short battery ter-
minals by allowing a wrench or any other object to
contact both terminals at the same time.
- A spark or ame can cause a lead acid battery to
explode.
- Before connecting a battery, remove metal
bracelets, wristwatch bands, rings, etc. Use gloves
and protective glasses or face shield when working
with a battery.
