BATTERY STORAGE AND
MAINTENANCE
Lead -acid type batteries are electro-chemical
devices for storing and releasing electrical
charge. As such, they are simply an electrical res-
ervoir, not an electrical source. As soon as energy
is removed from the battery, it should be replaced
by the engine alternator or the RV converter sys-
tem.
If a battery sits unused for 30 days or more, es-
pecially during warm weather, it can develop a
deposit of sulfate crystals on the metal plates in-
side the battery. This condition is called sulfation
or sulfating, and prevents the battery from either
releasing or accepting a charge. If this condition
occurs, the battery must be replaced.
If a battery does not contain at least 80%
charge during freezing temperatures, the electro-
lyte can freeze and crack the battery case.
The two best defenses against either sulfating
or insufficient charge are:
1. To disconnect the battery cables to avoid any
“parasitic” discharge, and
2. to check the battery and recharge as neces-
sary at least once a month during long
periods of storage.
A further precaution is to remove the battery
from the vehicle and store it in a cool location on
a wooden or rubber pad, checking charge period-
ically to avoid discharge or sulfating.
To ensure that the battery will always accept
and hold a charge, follow these simple mainte-
nance practices.
·
Make sure the batteries always remain se-
curely clamped in the battery tray.
·
Make sure battery cable clamps are tight on
the terminal posts and are free of corrosion.
·
Neutralize corrosion buildup or acid film on
top of battery by washing with a baking soda/
water solution. Rinse with clear water.
NOTE: Make sure vent caps are on securely to
prevent baking soda solution from enter-
ing the battery and contaminating the
electrolyte fluid.
·
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 electro-
lyte to prevent freezing.
·
Fluid level check may be omitted if equipped
with maintenance-free batteries.
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 discon-
nected.
Replace any damaged cables at once.
Always remove jewelry and wear
protective clothing and eye covering
when checking or handing batteries.
California Proposition 65 Warn-
ing:
Battery posts, terminals and
related accessories contain lead and
lead compounds, chemicals known to
the state of California to cause cancer
and reproductive harm. Wash hands
after handling.
