to the coach batteries, such as clock displays and
radio memories, etc.
Always leave this switch ON except during
storage periods. Some electronic displays and
memory functions may need to be reset after
power has been reconnected.

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.
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.)
2. Check the battery and recharge as necessary at
least once a month during long storage
periods. Turn the Aux. Batt. Switch off to
avoid electrical arcing when attaching or
detaching charger clamps.
NOTE: We do not recommend leaving the shore-
line plugged in continuously during stor-
age periods because the batteries can
lose electrolytic fluids and become dam-
aged from continuous charging without
periodic use or maintenance.
We recommend following regular bat-
tery inspection and maintenance, espe-
cially in cold weather.
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.

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.
