How to Handle
Battery
METHODS OF PREVENTING
OVER-DISCHARGE
The following precaulions
must be
taken to prevent
overdis-
charging a battery.
o The
battery surface (particularly
ils top) should always
be
kept clean and
dry.
lf the top surface of
a battery is
wet wilh electrolyte
or
water, leakage
current will cause the
battery to discharge.
Always keep
the battery
clean and dry.
When the vehicle is not going
to be used over a long period
ol time, disconnect the negative
battery terminal. (ll
the
vehicle has an extended storage
switch, turn it off.)
Check the charge
condition of the battery.
Periodically check the
specific gravity
of the
electrolyte.
Keep a close check
on charge condition
to prevent
over-
discharge.
CHECKING ELECTROLYTE
LEVEL
WARNING: Do not allow battery fluid
to come in contact with
skin, eyes,
fabrics, or painted
surfaces, After touching a
battery, do not
touch or rub your
eyes until you
have thoroughly washed your
hands. lf the
acid contacts the eyes,
skin or clothing, immedi-
ately flush with
water for 15 minutes
and seek medical atten-
tion.
Normally the
battery does not require
additional water.
However, when the
battery is used under severe
condilions,
adding distilled water may be necessary
during the battery life.
