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 coach
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 House/Coach Battery Disconnect
2. Check the battery and recharge as necessary at

Battery posts, terminals, and related
accessories contain lead and lead

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.
Check the state of charge periodically to avoid
discharge or sulfating.
To ensure that the battery will always accept
Make sure the batteries always remain
securely clamped in the battery tray.
