GENERAL INFORMATION
INTRODUCTION
The battery stores, stabilizes, and delivers electri-
cal current to operate various electrical systems in
the vehicle (Fig. 1). The determination of whether a
battery is good or bad is made by its ability to accept
a charge. It also must supply high-amperage current
for a long enough period to be able to start the vehi-
cle. The capability of the battery to store electrical
current comes from a chemical reaction. This reac-
tion takes place between the sulfuric acid solution
(electrolyte) and the lead +/- plates in each cell of the
battery. As the battery discharges, the plates react
with the acid from the electrolyte. When the charging
system charges the battery, the water is converted to
sulfuric acid in the battery. The concentration of acid
in the electrolyte is measured as specific gravity
using a hydrometer. The specific gravity indicates the
battery's state-of-charge.
The battery is vented to release gases that are cre-
ated when the battery is being charged and dis-
charged.
The battery top, posts, and terminals should be
cleaned when other under hood maintenance is per-
formed.
The battery top, posts, cable clamps must be
cleaned and battery must be completely charged
before diagnostic procedures are performed.

SAFETY PRECAUTIONS AND WARNINGS
WARNING:
DO NOT ALLOW JUMPER CABLE CLAMPS TO
TOUCH EACH OTHER WHEN CONNECTED TO A
BOOSTER SOURCE.
DO NOT USE OPEN FLAME NEAR BATTERY.
REMOVE
HANDS OR WRISTS TO AVOID INJURY BY ACCI-
DENTAL ARCING OF BATTERY CURRENT.
WHEN USING A HIGH OUTPUT BOOSTING
DEVICE, DO NOT ALLOW THE DISABLED VEHI-
CLE'S BATTERY TO EXCEED 16 VOLTS. PER-
SONAL INJURY OR DAMAGE TO ELECTRICAL
SYSTEM CAN RESULT.
TO PROTECT THE HANDS FROM BATTERY
ACID, A SUITABLE PAIR OF HEAVY DUTY RUB-
