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.

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).

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.

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)

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 Wink

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.

I have the following Fujitsu batteries and will post review of them:

But some other stuff will sneak in between the reviews.

Figured I’d post this over here as well:

So at some point between 2015 and 2016 Fujitsu has cheaped out on their batteries. They are using crappy washers. I ordered several of the regular white AA’s and noticed that the washers were not completely round, so when the cells were wrapped they appear “dented”. Also, a few of my batteries came with slightly damaged wrappers. I also ordered several of their high capacity black AA cells and the problems were worse. They are no longer using the blue-ish grey washer but instead use a black plastic washer. This new washer is inferior because when the cells are wrapped it leads to a loose fit around the positive end. The washer does not sit flush on the battery and is buckled up a little. I do not see this on the white cells and they use a plastic washer.

http://imgur.com/gallery/ym0HT

I spoke with a Fujitsu sales manager about this and he basically confirmed that they are using different materials in their high capacity cells because it is supposed to provide more longevity or something. Seems to me they got it wrong and the new materials will just lead to torn wrappers more easily. He also said the black washer is the same thing they have been using on their white cells, just black. This is not the case though.
