BATTERY MAINTENANCE
Automotive batteries store chemicals that react and
convert chemical energy into electrical energy. When
electrical energy resources are used the battery
drains and becomes discharged. Directing charging
current to the batteries from the engine alternator
(when the motorhome’s engine is running) or by
using the motorhome inverter/charger will recharge
the coach batteries and enable them to continue
functioning normally�
BATTERY PROBLEMS
Several conditions can destroy the battery’s function
including sulfation and freezing.
Sulfation occurs when lead sulfate crystallizes and
deposits on the negative plates inside the battery. This
condition is caused when a battery is deprived of a
full charge for an extended period of time (30 days
or more, especially during warm weather). If sulfation
occurs, you will have to replace the battery.
Freezing can discharge, damage or destroy a battery.
Batteries must be maintained at a nearly fully-charged
condition to prevent the liquid electrolyte inside the
battery from freezing.
A surge protection fuse is installed inside the
coach batter storage compartment
5
. If the
coach batteries fail to operate, inspect this
fuse and replace if necessary.
