1. Disconnect the battery. Negative wire must be disconnected first, and connect the last. Make sure that the top and the battery terminals are clean. |
2. The digital voltmeter, measure the voltage at the battery terminals. Make sure that the voltage shown by the digital voltmeter is 12.4 V or more. |
3. On 15 to connect to the terminals of the battery load input current of 300 A, and then wait for 5 minutes to stabilize the battery voltage. |
4. Connect to the terminals of the battery load input current of 50% of the battery capacity, 15 to measure the voltage and disconnect the load. |
5. The battery voltage varies depending on the temperature of the battery during the checking. |
