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
switch to avoid parasitic discharge (the trickle
discharge caused by directly connected
components like propane 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 House/Coach Battery
Disconnect switch off to avoid electrical
arcing when attaching or detaching charger
clamps.
