BATTERY VISUAL INSPECTION (1)

The battery contains a visual test indicator which gives a blue signal when an adequate charge level exists, and a white signal when charging is required.

BATTERY VISUAL INSPECTION (2)

Make sure the ignition switch is in "LOCK" (OFF) position and all battery fed accessories are OFF.

1. Disconnect the negative cable from battery before disconnecting the positive cable.

WARNING Care should be taken in the event battery case is cracked or leaking to protect hands from the electrolyte.

A suitable pair of rubber gloves (not the household type) should be worn when removing battery by hand.

2. Remove the battery from the vehicle.

3. Inspect the battery carrier for damage caused by loss of acid from battery. If acid damage is present, it is necessary to clean area with a solution of clean warm water and baking soda. Scrub area with a stiff bristle brush. Wipe clean with a cloth moistened with ammonia or baking soda in water.

4. Clean the battery, especially the top, with the same solutions as described in step 3.

5. Inspect the battery case and cover for cracks. If cracks are present, battery must be replaced.

6. Clean the battery post with a suitable battery post cleaning tool.

7. Clean the inside surfaces of the terminal clamps with a suitable battery terminal cleaning tool. Replace damaged or frayed cables and broken terminal clamps.

8. Install the battery in the vehicle.

9. Connect the positive and negative cables to the battery in the order of mention.

10.Tighten the clamp nut securely.

BATTERY CHARGING

WARNING When batteries are being charged, an explosive gas forms beneath the cover of each cell. Do not smoke near batteries on charge or which have recently been charged. Do not break live circuits at the terminals of the batteries on charge. A spark will occur where the live circuit is broken. Keep all open flames away from the battery.

Battery electrolyte temperature may temporarily be allowed to rise to 55 ºC (131 ºF). Increase of electrolyte temperature above 55 ºC (131 ºF) is harmful to the battery, causing deformation of battery cell, decrease in life of battery, etc.

CHARGE RATE

Recommended rate and time for fully discharged condition (flat discharged) is shown below. When the specific gravity of electrolyte keeps 1.22 to 1.29 for more than one hour, charging should be stopped.

BATTERY TEST

BATTERY TESTING PROCEDURE

STEP 1. Check the battery cables.

(1) Remove the negative cable, then the positive cable.

(2) Check for dirty or corroded connections.

Q: Are the battery cables dirty or have corroded connections?

YES : Clean the battery cables. Then go to Step 2.

NO : Go to Step 2.

STEP 2. Check the battery posts.

Check for loose battery post.

Q: Are the battery posts loose?

YES : Replace the battery.

NO : Go to Step 3.

STEP 3. Check the battery case and cover.

(1) Remove the hold-downs and shields.

(2) Check for broken/cracked case or cover.

Q: Is the battery case or cover faulty?

YES : Replace the battery.

NO : Go to Step 4.

STEP 4. Check the open circuit voltage.

(1) Turn headlights on for 15 seconds.

(2) Turn headlights off for two minutes to allow battery positive voltage to stabilize.

(3) Disconnect the battery cables.

(4) Read open circuit voltage.

Q: Is open circuit voltage 12.4 volts or more?

YES : Go to Step 6.

NO : Go to Step 5.

STEP 5. Battery charging

Charge the battery.

Q: Is open circuit voltage 12.4 volts or more?

YES : Go to Step 6.

NO : Replace the battery.

STEP 6. Check the load test.

(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)

Q: Is the voltage higher than minimum voltage?

YES : The battery is normal.

NO : Replace the battery.
