3. LOAD TEST
4. Damage and breakage due to heat.
3. Measure the voltage for the
2. 11.0V< battery voltage<12.0V due
3. Below 11.0V due to charge
4. Below 11.0V due to discharged for a
5. Below 11.0V due to internal short
4. Load test
- Conduct the test with a battery
1. Load test result: below 9.5V
2. Load test result: above 9.6V
1. Perform the following steps to complete the load test procedure for maintenance free batteries.
2. Connect the load tester clamps to the terminals and proceed with the test as follow :
A. If the battery has been on charge, remove the surface charge by connecting a 300 ampere load for 15 seconds.
B. Connect the voltmeter and apply the specified load.
C. Read the voltage after the load has been applied for 15 seconds.
D. Disconnect the load.
E. Compare the voltage reading with the minimum and replace the battery if battery test voltage is below that shown in
the voltage table.
20°C (70°F) and above
16 °C (60 °F)
10 °C (50 °F)
4 °C (40 °F)
-1 °C (30 °F)
-7 °C (20 °F)
-12 °C (10 °F)
-18 °C (0 °F)
- If the voltage is higher than shown in the table, the battery is good.
- If the voltage is lower than shown in the table, replace the battery.
BATTERY DIAGNOSTIC TEST (2)
1. Make sure the ignition switch and all accessories are in the OFF position.
2. Disconnect the battery cables (negative first).
3. Remove the battery from the vehicle.
Care should be taken in the event the battery case is cracked or leaking, to protect your skin from the electrolyte.
