What is a battery discharge test?

Do you need a battery discharge test?

Although the discharge test is a true test of the battery and provides valuable information, people are generally reluctant to do discharge testing, primarily because it is labor-intensive and time-consuming. It is also one of those tests that needs to be done right the first time on that day.

How do you discharge a battery?

One common manual discharge technique is to use a resistor as the load. The resistance value should be chosen based on the battery’s voltage and capacity to ensure the load current is within safe limits. This method is simple and inexpensive, but it can be inefficient and generate a lot of heat, which can shorten the battery’s lifespan.

Can a battery discharge test be restarted immediately?

If a mistake is made while starting the test, the test cannot be restarted immediately because the battery discharge data can be affected by the previous attempt. Proper planning and preparation will ensure that there are no hiccups and a discharge test can be carried out in the right manner and with ease.
