What is a battery capacity test?

The battery capacity test is to charge the battery to 100% SOC at 0.33C, and then discharge it to the discharge termination voltage at 0.33C, and calculate the amount of power released by the battery during the discharge process.

How do you test a battery Ah capacity?

Charge the battery fully. Use a constant current load such as an LM317 configured as a current load to discharge at say a 0.05C rate. When the per cell voltage (not battery voltage) reaches 3.2 volts, stop the test and record the total time. Multiply the time in hours by the current of the constant current load and you have the AH capacity.
