Battery

WARNING!
Risk of fire and explosion. Never allow an open flame
or electric sparks near the batteries.
WARNING!
Battery electrolyte is a corrosive acid and should be
handled with care. If you spill or splash electrolyte on
any part of the body, immediately flush the exposed
area with liberal amounts of water and seek medical
attention as soon as possible.
WARNING!
Ventilate the engine compartment before working on
batteries or battery connections.
IMPORTANT:
Batteries can be damaged if they are left discharged,
and can also freeze and burst easier in cold weather.
If the engine is not going to be used for a longer period
of time, the batteries should be fully charged, trickle
charged if possible.
Maintenance
It is important to always follow the battery
manufacture's recommendation and instruction when
replacing and charging batteries. Depending on
battery type, the instructions for maintenance and
charging may vary.
Modern batteries are normally maintenance free, but
there are some actions that are recommended to
increase the battery service life and avoid accidents:
• Keep the batteries clean and dry. Contamination
and oxide on the batteries and battery poles can
result in stray currents, voltage drop and discharge,
especially in wet weather.
• Remove oxidation from the battery poles and
terminals, using a brass brush.
• Tighten the terminals securely and grease them with
terminal grease or petroleum jelly. Loose battery
connections may cause damage to the engine's
electrical system.
•
Charge the battery regularly. A battery that is kept
fully loaded has a maximum service life. The easiest
way to check if a battery needs charging is to use a
voltmeter.
