•
Clean and tighten battery terminals and have
the specific gravity checked at least once a
year.
•
Every two months, or more often in hot
weather, check the battery fluid level. Fill to
approximately 3/8 inch above the plates. DO
NOT OVERFILL. If fluid is added during
freezing weather, the motor home should be
driven several miles to mix water and
electrolyte to prevent freezing.
•
Fluid level check may be omitted if equipped
with maintenance-free batteries.

WARNING
Before removing any battery cables or
battery, make sure all 12-volt equipment
in the motor home is off and the power
cord has been disconnected.
Be sure to replace the battery terminal
boot back onto the positive terminal after
servicing. Care must be taken to avoid
pinching the cable between any metal
parts. Should the cable be damaged, a
short circuit could result in personal injury
or damage to equipment.
Replace any damaged cables at once.
Always remove jewelry and wear
protective clothing and eye covering
when checking or handling batteries.
WARNING
To prevent wiring damage, it is essential
when replacing the cables on the battery,
or when using a “booster” battery, that the
positive post and the positive cable be
attached and the negative post and
negative cable be attached. The posts are
marked (+) plus and (-) minus.
If a “boost charger” is used while battery
is in the motor home, disconnect both
battery cables before connecting the
charger to avoid damage to engine
electronic components.
Never attempt to charge or boost a frozen
battery.
