The battery capacity test measures how much capacity (current x time) in ampere-hours, Ah, the battery can deliver before the terminal voltage is reached. The measurement assumes the current flow shall be maintained at a constant rate. For a lead-acid battery, the test time is approximated to be near the battery’s.

AI Customer ServiceAlso known as load testing, or discharge testing, capacity testing is a dynamic test whereby a simulated load (in amperes or watts) is imposed on the battery system for a specified time. The discharge continues to a defined end-of-discharge (EOD) voltage, referencing a measured battery temperature taken at the start of the test.
By measuring the voltage across the battery, its remaining capacity can be preliminarily estimated. The constant current discharge method is a more accurate battery capacity test method. Connect the battery to a certain load and discharge it at a constant current until the battery voltage drops to the predetermined cut-off voltage.
When the test time reaches three hours, the battery voltage would be 105V for a capacity of 100%. Test results frequently result in a capacity of more than 100%, which is why it is important the test be run to the EOD voltage rather than terminating the test at 100% capacity.
The capacity corrected to 25°C is 88.7% and the battery passed the test. Failure to use K t results in a capacity calculation of 96.7%, an error of 8%. The only way to know the capacity of a battery is to perform a capacity test under specific test conditions. Tests should be conducted periodically based on the applicable IEEE recommended practice.
The battery capacity test time can also be shortened to for example 1hr or 2hrs. The trick is to increase the current rate. The main advantage is that less capacity of the battery is drained out and this is more so in lead-acid batteries where low voltage may damage the battery.
By measuring the discharge time and combining the current value, the battery capacity can be accurately calculated. This method is relatively simple to operate and the results are relatively reliable, but it requires certain experimental equipment and technical support. 3.
