CAUTION:
a. lf
it
becomes neoessary to start the engine with
a booster
battery and jumper
cables, use a 12-volt
booster battery.
b. After
connec-ting battery cables,
ensure that they are tightly
clamped to batlery
terminals lor good
contact.
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.

SULPHATION
When a baftery has
been left
unattended for a long period
of
time and has a specific gravity
ot less than 1.100, it will
be
completely discharged, resulting in sulphation on
the cell
plates.
Compared with a battery discharged under normal conditions,
the current flow in a "sulphated"
battery is not as smooth
although its voltage is high
during the initial
stage of charging,
as shown in
the figure
at the left.
SPECIFIC GRAV]TY CHECK
1 . Read hydrometer and thermometer indications
at eye level.
o When
electrolyte level is
too low,
tilt battery case to raise it
for easy measurement.
2. Convert into
specitic gravity
at 20'C (68"F).
Examole:
o When
electrolyte temperature is
35"C (95'F)
and specific
gravity of electrolyte is 1 .230, converted specific gravity
at
20'C (68'F)
is 1.240.
o When
electrolyte
temperalure is
0"C (32"F)
and specific
gravity of electrolyte is 1 .210,
converted specific gravity
at
20'C (68'F)
is 1 .196.

CAUTION:
a. Set charging current
to value
specified in Fig. 2. lf
charger
is not
capable of producing
specified current value,
set its
charging current as close
to that value as possible.
b. Keep
battery away lrom
open flame while
it is being
charged.
c, When connecting charger, connect leads
first, then
turn on
charger. Do not
turn on charger first,
as this may cause a
spark.
d. lf
battery temperature rises
above 60"C (140'F),
stop charg-
