A b a t t e r y is t h e h e a r t of a vehicle's electrical sys-

i g n i t i o n system w h i l e t h e engine is s t a r t i n g , i t also
acts as power supply t o operate lamps, radio, and ac-
cessories w i t h engine off. Second i t i n t e r m i t t e n t l y
supplies energy for electrical loads when t h e engine
is r u n n i n g and load demands are more t h a n o u t p u t
of alternator. T h i r d i t acts as a voltage stabilizer i n
the electrical system. The battery evens o u t tempo-

electrical system parts. To do t h i s the battery con-
verts chemical energy into electrical energy by a
chemical reaction.
I f a battery is not u p to specifications i t w i l l not de-
l i v e r necessary electricity, w i l l not accept electricity
and w i l l n o t act as a capacitor. Consequently, the ve-
hicle's e n t i r e electrical system w i l l be effected w h e n
t h i s happens.
Standard
equipment
maintenance-free
batteries
(Fig. 1) have no removable battery cell caps. Water
can n o t be added to t h e maintenance-free
battery.
The b a t t e r y is completely sealed, except for s m a l l
vent holes i n t h e cover. These vent holes allow w h a t
s m a l l a m o u n t of gasses are produced i n t h e battery
to escape. Special chemical composition inside t h e
b a t t e r y reduces production o f gas to a n extremely

t e r y contains a v i s u a l test indicator w h i c h signals

BATTERY VISUAL INSPECTION AND SERVICE
(1) M a k e sure i g n i t i o n switch is on O F F position
and a l l b a t t e r y feed accessories are O F F .
(2) Disconnect both battery cables s t a r t i n g w i t h the
Negative cable.
WARNING: CARE SHOULD BE TAKEN, IN THE
EVENT BATTERY CASE IS CRACKED OR LEAKING.
TO
PROTECT HANDS FROM ELECTROLYTE, A
SUITABLE PAIR OF RUBBER GLOVES (NOT THE
HOUSEHOLD TYPE) SHOULD BE WORN WHEN RE-
MOVING BATTERY BY HAND.
