B: INSPECTION
1. BATTERY
1) External parts
Check for the existence of dirt or cracks on the battery
case, top cover, vent plugs, and terminal posts. If
necessary, clean with water and wipe with a dry cloth.
Apply a thin coat of grease on the terminal posts to prevent
corrosion.
2) Electrolyte level
Check the electrolyte level in each cell. If the level is below
MIN LEVEL, bring the level to MAX LEVEL by pouring dis-
tilled water into the battery cell. Do not fill beyond MAX
LEVEL.
WARNING:

Electrolyte has toxicity; be careful handling the
fluid.

Avoid contact with skin, eyes or clothing. Especially
at contact with eyes, blush with water for 15 minutes
and get prompt medical attention.

Batteries produce explosive gasses. Keep sparks,
flame, cigarettes away.

Ventilate when charging or using in enclosed space.

For safety, in case an explosion does occur, wear
eye protection or shield your eyes when working near
any battery. Never lean over a battery.

Do not let battery fluid contact eyes, skin, fabrics, or
paint-work because battery fluid is corrosive acid.

To lessen the risk of sparks, remove rings, metal
watch-bands, and other metal jewelry. Never allow
metal tools to contact the positive battery terminal and
anything connected to it while you are at the same time
in contact with any other metallic portion of the vehicle
because a short circuit will be caused.

3) Specific gravity of electrolyte
Measure specific gravity of electrolyte using a hydrometer
and a thermometer.
Specific gravity varies with temperature of electrolyte so
that it must be corrected at 20°C (68°F) using the follow-
ing equation:
S
20= St + 0.0007 x (t 20)
S
20:Specific gravity corrected at electrolyte tempera-
ture of 20°C (68°F)
St :Measured specific gravity
t :Measured temperature °C
Determine whether or not battery must be charged,
according to corrected specific gravity.
Standard specific gravity: 1.220 — 1.290 [at 20°C
(68°F)]
Measuring the specific gravity of the electrolyte in the bat-
tery will disclose the state of charge of the battery. The
relation between the specific gravity and the state of
charge is as shown in figure.
C: CHARGING
WARNING:

Do not bring an open flame close to the battery at
this time.
CAUTION:

Prior to charging, corroded terminals should be
cleaned with a brush and common baking soda solu-
tion.

Be careful since battery electrolyte overflows while
charging the battery.

Observe instructions when handling battery
charger.

Before charging the battery on vehicle, disconnect
battery ground terminal. Failure to follow this rule may
damage generator’s diodes or other electrical units.
1. NORMAL CHARGING
Charge the battery at current value specified by manufac-
turer or at approximately 1/10 of battery’s ampere hour
rating.
2. QUICK CHARGING
Quick charging is a method in which the battery is charged
in a short period of time with a relatively large current by
using a quick charger.
Since a large current flow raises electrolyte temperature,
the battery is subject to damage if the large current is used
for prolonged time. For this reason, the quick charging
must be carried out within a current range that will not
increase the electrolyte temperature above 40°C (104°F).
It should be also remembered that the quick charging is a
temporary means to bring battery voltage up to a fair value
and, as a rule, a battery should be charged slowly with a
low current.
