Test Procedure
|
|
Regarding the battery check and battery charge method.
-
If battery has description, follow it.
-
When you charge the battery, you must remove the battery from the vehicle.
|
-
Check for damage: If the case is cracked or the terminals are loose, replace the battery.
-
Check the test indicator window.
-
If the test indicator window indicates the shortage of battery liquid, go to
Step 3
.
-
If the test indicator window indicates a low charge, go to
Step 4
.
-
Remove the tape and caps, and add distilled water. After refill the distilled water apply the tape and caps.
-
Test battery load capacity by connecting a battery tester, and applying a load of three times the battery ampere hour rating.
When the load has been applied for exactly 15 seconds, the battery voltage reading should stay above 9.6 V.
-
If the reading stays above 9.6 V, the battery is OK; clean its terminals and case, and reinstall it.
-
If the reading is between 6.5 and 9.6 V, connect a battery charger and charge the battery for 3 minutes at an initial rate of 40 amps.
|
|
|
Amperage will drop as voltage increases; do not increase the amperage to compensate or you may damage the battery.
|
|
|
Since the main body of the battery is transformed or might be exploded by gas generated when charging it, loosen the cap of each cell of the battery completely when you charge the battery.
|
-
If the reading drops below 6.5 V, slow-charge the battery by connecting a battery, and charge at 5 amps for no more than 24 hours (or until the indicator shows full charge, or the specific gravity of the electrolyte is at least 1.270).
Then test load capacity again.
| -
|
If the voltage stays above 9.6 V, the battery is OK; clean its terminals and case, and reinstall it.
|
| -
|
If the voltage still drops below 6.5 V, the battery is not good; replace it.
