WARNING: AVOID SPARKS AND ALL SOURCES OF IGNITION WHEN WORKING ON THE BATTERY.

CAUTION: Do not carry out this test if the battery voltage is below 12.5 volts.

CAUTION: Do not carry out this test for longer than 15 seconds or damage to the battery may occur.

NOTE: Make sure that the high rate discharge tester is capable of applying a load of 300 Amps to the battery.

1. Connect the high rate discharge tester to the battery.
2. Observe and record the voltage reading of the battery.
3. Turn the switch to the ON position for 15 seconds.
4. Observe and record the minimum voltage reading of the battery.
5. Turn the switch to the OFF position.
6. Observe the voltage reading of the battery.

The battery voltage should not fall below 9.6 volts at a temperature of 21 °C (70 °F) when carrying out the test. The battery should recover to the original voltage when the test is complete.
