WARNING
Refasten the retainer strap when returning the battery to the compartment.
Lead-acid type batteries are electro-chemical devices for storing and releasing electrical charge. As such,
they are simply an electrical reservoir, 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 system.
If a battery sits unused for 30 days or more, especially during warm weather, it can develop a deposit of
sulfate crystals on the metal plates inside the battery. This condition is called 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 electrolyte can freeze
and crack the battery case.
The two best defenses
against sulfating and insufficient charge are to:
1.
Turn off the Auxiliary Battery switch to avoid parasitic discharge (the trickle discharge caused by directly
connected components like LP gas detectors or digital clock displays, etc.), and
2.
Check the battery and recharge as necessary at least once a month during long storage periods.
Further precautions are:
Remove the battery from the coach.
Store it in a cool place on a wooden or rubber pad to inhibit conductive transfer.
Check the state of charge periodically to avoid discharge or sulfating.
To ensure that the battery will always accept and hold a charge, follow these simple maintenance practices.
Make sure the batteries always remain securely 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 entering the battery and
contaminating the electrolyte fluid.
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.
Replace any damaged cables at once.
Always remove jewelry and wear protective clothing and eye covering when checking or handling
batteries.
Refasten the retainer strap when returning the battery to the compartment.
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.
