This area was created to share experiences I have found with NiMH AA batteries.

As all photographers know these are a key component in our flashes.

Below are the result from test I have done on varies brands, and capacities so far.

No company has supplied these batteries, they have all been bought using my own money.
So there is no bias at all in the result below.

I will be adding to the test slowly.
If you are interested in having a certain battery manufacture tested, please e-mail me directly at: with the information.

Currently I am only doing AA's, but plan on adding BP-511 series soon.

From the best I can find all NiMH have a tolerance of +/- 10%.
If this is incorrect, please let me know.
