What is a battery capacity test?

Capacity test is the only way to get an accurate value on the actual capacity of the battery. While used regularly it can be used for tracking the battery’s health and actual capacity and estimating remaining life of the battery. When the battery is new its capacity might be slightly lower than specified. This is normal.

What is a battery test?

During the test it is measured how much capacity (current x time expressed in Ah) the battery can deliver before the terminal voltage drops to the end of discharge voltage x number of cells. The current shall be maintained at a constant value.

What is a battery testing matrix?

The Battery testing matrix below may help guide even the most skilled battery testing technician and will help simplify the recommended practices. The following is a description of some of the tests or maintenance parameters. Capacity test is the only way to get an accurate value on the actual capacity of the battery.

How does a battery test work?

When used regularly it can be used for tracking the battery’s health and actual capacity and estimate remaining life of the battery. During the test it is measured how much capacity (current x time expressed in Ah) the battery can deliver before the terminal voltage drops to the end of discharge voltage x number of cells.

What are the standards for battery testing?

There are a number of standards and company practices for battery testing. Usually they comprise inspections (observations, actions and measurements done under normal float condition) and capacity tests. Most well-known are the IEEE standards:

When should I perform a battery capacity test?

Perform a capacity test annually when the battery has reached 85% of expected service life or if the capacity has dropped more than 10% since the previous test or is below 90% of the manufacturer‘s rating. Perform a capacity test if the Impedance value has changed significantly.
