AA NiMH Battery Performance Test Results

The up to date AA Great Battery Shootout and Showdown.

The AA NiMH Battery Performance test reveals the ACTUAL capacity ( also known as mAh ) or energy delivered ( also known as Wh ) from each AA NiMH Battery. see Glossary for more information.

AA Rechargeable Battery Editors Choice Awards

AA NiMH battery performance is also an indicator of quality or value. If you paid for a 2900 mAh AA battery, would you be satisfied with the performance of a 2500 mAh battery?

Do you want to know how the AA NiMH battery performance test is done or how we calculate the capacity? ( see FAQs and Info )

 

Understanding the AA NiMH Battery Performance

The AA NiMH battery performance test results below are easy to understand. The column "Actual Capacity (%)" is a calculation of the percentage of the total capacity delivered.

Example : If a AA NiMH battery label says 2000 mAh and the AA NiMH battery delivers only 1800 mAh, then the battery delivered only 90%. You only got 90% of what you paid for.

100% is expected. A higher the number means a better battery.

For more information on the AA NiMH Battery Performance Test, check out the Test Methodology section for a description.

Due to the time required to complete all the tests, some of the fields may be blank. We will be updating them as we complete each test.

 

Sort the AA NiMH Battery Performance Test Results on the Fly

Clicking once on the header will sort in ascending order ( smallest on top ). Clicking again will sort in descending order ( biggest on top ).

The individual headers looks like a link. Once you click on a link, a small arrow indicating the order should appear.
