BATTERY CARE

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.
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 Disconnect
2. Check the battery and recharge as necessary at

Further precautions are:
If a battery does not contain at least 80%

(the trickle discharge caused by directly
connected components like propane gas
detectors or digital clock displays, etc.)
least once a month during long storage
periods. Turn the Aux Batt Switch off to avoid
electrical arcing when attaching or detaching
charger clamps.
WARNING
California Proposition 65 Warning:
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.
shoreline plugged in continuously during
storage periods because the batteries can
lose electrolytic fluids and become
damaged from continuous charging
without periodic use or maintenance.
We recommend following regular battery
inspection and maintenance, especially
in cold weather.
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.
