Load Test
- Perform the following steps to complete the load test procedure for maintenance free batteries.
- Connect the load tester clamps to the terminals and proceed with the test as follow:
- If the battery has been on charge, remove the surface charge by connect a 300 ampere load for 15 seconds.
- Connect the voltmeter and apply the specified load.
- Read the voltage after the load has been applied for 15 seconds.
- Disconnect the load.
- Compare the voltage reading with the minimum and replace the battery if battery test voltage is below that shown in the voltage table.
VOLTAGE CHARTVoltage Temperature 9.6 V 20 °C (68.0 °F) and above 9.5 V 16 °C (60.8 °F) 9.4 V 10 °C (50.0 °F) 9.3 V 4 °C (39.2 °F) 9.1 V -1 °C (30.2 °F) 8.9 V -7 °C (19.4 °F) 8.7 V -12 °C (10.4 °F) 8.5 V -18 °C (-0.4 °F) NOTE:- If the voltage is greater shown in the table, the battery is good.
- If the voltage is less than shown in the table, replace the battery.
