These cells are high capacity NiMH from the FDK factory in Japan.

There is very good tracking between the two cells. They can handle 10A current, but as usual it is better to use a lower current.


These cell has very good performance.

Notes and links

The batteries was supplied by FDK German for a review.

How is the test done and how to read the charts
Compare to other AA/AAA batteries: Alkaline/NiMH/Lithium

Thank you for the great review! Always a pleasure to read them.

Thanks HKJ! Good to see some more NiMh cells being tested!

There are many more, I have 3 more Fujitsu, Amazon basic and a lot of other.

Looking forward to your tests.

Anything almost done testing?

The 3 Fujitsu and 4 other cells are done testing and just need publishing, I do also have a few special that are done testing.

At the current time I am testing on the Amazon basic.

I may have to increase my publishing rate slightly to publish all the stuff I have (This will mostly be usb power banks and power supplies).

Thanks for the testing!!

Thanks HKJ, for the review and the “forecast”. Are these Fujitsu the white(ish) ones?

Thank you very much for these battery reviews. These Fujitsu batteries seems to perform very well similar to the eneloops.

I can’t wait to see how the Amazon basic batteries compared to the eneloops.

Yes ;)



can you explain that kloppholz, because Fujitsu has a few kind of nimh batteries, and these black ones are different from the white ones.. so Im not sure what your question was, but these are different from their white sibblings!

Fujitsu has their old series of NiMH and then they have a series from the FDK factory. The white ones is from the FDK factory (Like the black ones here).

Maybe you can explain what white(ish) means? maybe it has a meaning. But the white fujitsu are not the same as teh black ones. different capacity.

its like the standard eneloop (white) vs the PRO eneloop (black)

Exactly, that is also the reason they will be posted in another review.

ah.. now I see... I think Kloppholz was referring to the "forecast" batteries.. and said THESE..

he should have written THOSE..

I thought he was referring to THESE black fujitsu...

just a language problem ;)

Sorry to go OT, but congratulations on 4000 Posts, ChibiM.

Looking forward to the Amazon basic tests, HKJ.

In some pictures the batteries look white, in other like a creme colored, like the the Amazon basics have. HKJ already mentioned the factory.



Those are different than the black ones, you confused me. As it looks like you were saying the blacks are the same as the white ones.

I know very well what Fujitsu is offering therefore my comment ;)

No, I just wanted to know if the Fujitsu’s HKJ has in the pipeline, are the white version. No single word about that both versions are the same. Sorry if this caused confusion.
