I did not realize there were 2 versions of the Amazon Black AA: 2000mAh and 2400mAh

For some reason I thought the White AA was 2000mAh, but it is only 800mAh, same as the AAA, according to Amazon. Can that be correct?

Maybe there is a typo on the Amazon (USA) website? At the top of the page, the capacity is shown as 800mAh for the White AA, but lower down the page, it is shown as 1900mAh minimum.

It will be interesting to see how the Black AA and the White AA compare to one another in your testing, given that they are both rated at 1900mAH. Apparently, the Black AA is manufactured in China, and the White AA is manufactured in Japan, from what I read at Amazon.

Interesting, they sag more than Eneloops but the rest of the discharge seems very similar to many other 2000mAh batteries that are out there.

These seem to be identical in performance, as seen with the HKJ Comparator, to the IKEA Ladda AA that were tested by HKJ in February.

Anyone know how they compare in price?

Did a little price research:
IKEA sells a 4-pack of Ladda AA online for $5.99
Amazon sells a 4-pack of White Basics AA for $10.79
Amazon sells a 16-pack of Black Basics AA for $26.69 (or $6.67 per 4 batteries)
Amazon sells a 4-pack of Eneloop AA for $13.99

I've been comparing them too. I guess the white ones are the "good" ones, from what I see in the reviews.

Do they? We can't buy anything online from the Ikea's here. Also when you get notification of stock arrival, it sells out in less than a week!

Thanks for the review HKJ.

Questions on testing NiMhs, if you don't mind - do you do any type of "break-in" or condition cycling of the cells before testing them? Have you found that LSD cells that are new, but have been stored in a charged state for some time, tend to develop some internal resistance?

Thanks

Usual I do not, but with a few cells I have done it.
You will sometimes see that the 0.1A track has less capacity than the 0.2A track, that is because the cell would have benefited from a break-in.

The white ones are 2000mah typical, 1900mah minimum, made in Japan and charged with solar energy. Does that sound familiar?
