ON-VEHICLE SERVICE

FLUID LEVEL AND SPECIFIC GRAVITY CHECK

1.

Inspect whether or not the battery fluid is between the
UPPER LEVEL and LOWER LEVEL marks.

Caution
(1) If the battery fluid is below the LOWER LEVEL,

the battery could explode in using.

(2) If the battery fluid is over the UPPER LEVEL,

leakage could result.

2.

Use a hydrometer and thermometer to check the specific
gravity of the battery fluid.

Standard value: 1.220 – 1.290 [20

_

C]

The specific gravity of the battery fluid varies with the
temperature, so use the following formula to calculate
the specific gravity for 20

_

C. Use the calculated value

to determine whether or not the specific gravity is
satisfactory.

D20 = (t  –  20)

CHARGING

1.

When charging a battery while still installed in the vehicle,
disconnect the battery cables to prevent damage to
electrical parts.

2.

The current normally used for charging a battery should
be approximately 1/10th of the battery capacity. When
performing a quick-charging due to lack of time, etc., the
charging current should never exceed the battery capacity
as indicated in amperes.

3.

Determining if charging is completed.
(1) If the specific gravity of the battery fluid reaches 1.250

– 1.290 and remains constant for at least one hour.

(2) If the voltage of each cell reaches 2.5 – 2.8 V and

remains constant for at least one hour.

Caution
(1) Remove the battery caps during charging.
(2) Be careful since the battery fluid level may rise

during charging.

(3) Keep all sources of fire away while charging

because there is a danger of explosion.

(4) Be careful not to do anything that could generate

sparks while charging.

(5) When charging is completed, replace the battery

caps, pour clean water over the battery to remove
any sulfuric acid and dry.

(6) Perform the charging in the well-ventilated place.
(7) Do not raise the battery fluid temperature more

than approximately 45

_

C (In case of quick-

charging: approximately 55

_

C).

BATTERY TESTING PROCEDURE

TEST STEP

(1) Turn headlamps on for 15 seconds.
(2) Turn headlamps off for 2 minutes to allow battery voltage

to stabilize.

(3) Disconnect cables.

OK

Read open circuit voltage.

OK: Open circuit voltage is more than 12.4 V

NG

Charge battery at 5 amps. (see LOAD TEST RATE CHART)

Retest

OK

(1) Connect a load tester to the battery.
(2) Load the battery at the recommended discharge rate (see

LOAD TEST RATE CHART) for 15 seconds.

(3) Read voltage after 15 seconds, then remove load.
(4) Compare the measured value with the minimum voltage (see

LOAD TEST CHART).
OK: Higher than minimum voltage

NG

Replace battery
