Battery System
To avoid fire and explosion when working with a battery:
• Do not overfill a battery with sulfuric acid.
• Do not smoke or bring flames near a battery that is being
or recently been charged. Hydrogen gas generated by the
battery charging is highly explosive.
• Never short out the battery terminals, including when
checking the remaining battery charge.
Failure to follow the above safety messages could result in
death or serious injury.
Frequently check your battery terminals for corrosion build-up. If you
weather. The level should be maintained between the top of the battery
plates and the bottom of the fill cap opening. Add distilled water as
needed after charging the batteries or periodically as
Set batteries on a block of wood rather than concrete since this
procedure will help the batteries from losing their charge.

Cosmetic Care & Maintenance
!
WARNING
find a greenish, powdery substance, remove the
cable connections and clean both the both the
terminals and the connectors with a wire brush.
When the cleaning is finished reconnect the
battery cables and coat the terminal with an
approved grease or petroleum jelly to help
prevent further corrosion. Check the electrolyte
level at least every 30 days, more often in hot
needed. Do not overfill as sulfuric acid could
run over and cause burns or an explosion.
Batteries should be charged outside the boat.
Do not smoke or bring flames near a battery
that is being or has recently been charged.
The hydrogen gas generated by battery
charging is highly explosive.
