DESCRIPTION AND OPERATION
BATTERY
DESCRIPTION
A large capacity, low-maintenance storage battery
is
standard
factory-installed
equipment
on
this
model. This battery is designed to provide a safe, effi-
cient and reliable means of storing electrical energy
in a chemical form. This means of energy storage
allows the battery to produce the electrical energy
required to operate the engine starting system, as
well as to operate many of the other vehicle acces-
sory systems for limited durations while the engine
and/or the charging system are not operating.
The factory-installed low-maintenance bat-
tery has removable battery cell caps. Water can
be added to this battery. The battery is not sealed
and has vent holes in the cell caps (Fig. 1). The
chemical composition within the low-maintenance
battery reduces battery gassing and water loss, at
normal charge and discharge rates.
Rapid loss of electrolyte can be caused by an over-
charging condition. Be certain to diagnose the charg-
ing system before returning the vehicle to service.
Refer to Charging System in the Diagnosis and
Testing section of Group 8C - Charging System for
more information.
The factory-installed battery also has a built-in
test indicator (hydrometer). The color visible in the
sight glass of the indicator will reveal the battery
condition. Refer to Built-In Test Indicator in the
Diagnosis and Testing section of this group for more
information.
This group covers only the battery diagnostic and
service procedures. For battery maintenance sched-
ules and jump starting procedures, see the owner’s
manual in the vehicle glove box, or refer to Mainte-
nance Schedules and Jump Starting, Towing
and Hoisting in Group 0 - Lubrication and Mainte-
nance. While battery charging can be considered a
maintenance procedure, battery charging information
is located in this group. This was done because the
battery must be fully-charged before any diagnosis
can be performed.
Group 8A covers the Battery, Group 8B covers the
Starting Systems, and Group 8C covers the Charging
System. We have separated these systems to make it
easier to locate the information you are seeking
within this Service Manual. However, when attempt-
ing to diagnose any of these systems, it is important
that you keep their interdependency in mind.
The battery, starting, and charging systems in the
vehicle operate with one another, and must be tested
as a complete system. In order for the vehicle to start
and charge properly, all of the components that are
used in these systems must perform within specifica-
tions. It is important that the battery, starting, and
charging systems be thoroughly tested and inspected
any time a battery needs to be charged or replaced.
The cause of abnormal discharge, overcharging, or
early battery failure must be diagnosed and corrected
before a battery is replaced or returned to service.
