Battery: Testing and Inspection

BATTERY VISUAL INSPECTION(1)




1. CHECKING FLOW




2. CHECKING SHEET

3. load Test




1. When discharging the battery for 15 seconds at half the rated current, the battery voltage should be more than the voltage shown in the above table.
2. when the voltage is not within specification, test 2nd load test again, and if not, do the re-charge.
3. If the battery voltage (left alone within 2 hours after recharging) is over 12.5 V and the voltage after load test is over the standard value, this battery can be used.

BATTERY INSPECTION (2)




1. Make sure ignition switch is in the Off position and all accessories are Off.
2. Disconnect the battery cables (negative first).
3. Remove the battery from the vehicle.

WARNING: Care should be taken because of the risk that the battery case is cracked or leaking to protect your skin from the battery electrolyte. A suitable pair of industrial rubber gloves should be worn when removing the battery. Do not use household cleaning gloves when handling the battery.




4. Inspect the battery carrier for damage caused by the loss of acid from the battery. If acid damage is present, it will be necessary to clean the area with a solution of clean warm water and baking soda. Scrub the area with a stiff brush and wipe off with a cloth moistened with baking soda and water.
5. Clean the top of the battery with the same solution as described in Step4..
6. Inspect the battery case, and cover, for cracks. If cracks are present, the battery must be replaced.
7. Clean the battery posts with a suitable battery post cleaner.
8. Clean the inside surface of the terminal clamps with a suitable battery terminal cleaning tool. Replace damaged or frayed cables and broken terminal clamps.

9. Install the battery in the vehicle.
10. Connect the cable terminals to the battery post, making sure the top of the terminal are flush with the top of the post.
11. Tighten the terminal nut securely.
12. Coat all connections with light mineral grease after tightening.

WARNING: When batteries are being charged, an explosive gas forms beneath the cover of each cell. Do not use open flames or smoke near batteries being charged or which have recently been charged. Do not break live circuits at the terminals of the batteries being charged. A spark will occur where the circuit is broken, which could ignite the fumes and cause an explosion.
