The battery does very fine up to 1 or 2A, but 5A is definitely to much.

Conclusion

This is the first AAA NiMH battery I have tested and I cannot say anything about performance compared to other NiMH AAA batteries.

They look pretty good, i am shocked then can do 3A without any problems, even 5A doesn’t look horrible but for those small batteries i would not push them much anyways.

"It is critical that there is a credible academic source for the growing and important discipline of alternative facts. This field of study will just keep winning, and we knew that all the best people would want to be on board. There is a real risk in the world today that people might be getting their information about science from actual scientists"

Thanks a lot!
Please find the time to test the standard (white) AAA eneloop so that we can compare.

My English isn’t perfect but I’m trying to improve it. If you see something that doesn’t sound right or is just plain wrong, please feel free to point it out! Smile

I was planning on it, but I have a couple of other NiMH batteries first.

Wow the 2A power curve is fairly nice…I would bet a primary alkaline probably couldn’t push that without dropping out alot faster

Incredible review once again HKJ…awesome!

Do a few alkaline primary discharge graphs as well…yeah…kinda sucky doing a one shot kill of em…but it gives a baseline to compare to (as in what can these rechargeables do compared to the one shot wonders)

Even alkaline AA cannot match a eneloop AAA.
