This is a follow-up of sorts to my NiMH Battery Roundup video, except this time I’m looking at triple-As, and only one brand.
I was vexed by the fact that Amazon had EBL AAA cells with an 1100mAh capacity for only 7 cents more per cell than the otherwise-identical 800mAh variety. That didn’t make sense to me, and besides, 1100mAh is rather high for a AAA package size. Hence I bought a bunch of each and tested them.
The Bottom Line
The 1100mAh cells appear to be a big fat lie. The average capacity for those clocked in at 980mAh, with one cell showing as low as 946mAh and the highest at 1005mAh.
The 800mAh cells were respectable at an average of 809mAh, and less of a variance between cells.
Despite the fact that the “1100mAh” units were well under capacity, they are of course the better deal coming in at 852mAh per dollar with the 800mAh cells giving 749mAh per dollar.
I wish I had the time, inclination, or money to pit a whole bunch of AAA brands against each other, but I’m satisfied in imagining that quality scales from my AA cell results.
Not to spoil the video, but if you’re here for a recommendation: At the current price of $21.99 for a sixteen pack, the EBL 2300mAh cells are the way to go. However, I’d also recommend the high capacity cells by Amazon and Sunlabz.
I own a bunch of Panasonic Eneloop cells, and they are reliable, well made, and meet or exceed their advertised capacity. I’d absolutely recommend Eneloops or Eneloop Pros, at the right price. They can be catastrophically expensive, which is the only reason they aren’t my first recommendation. The EBL and Sunlabz cells give much better value for money.
A look at some possibly-fake random “NiMH” AA cells from AliExpress, comparing them to Panasonic Eneloop cells.
From my somewhat limited testing, these little green guys had an actual capacity of about 342mAh, which is less than 10% of their claimed specification of 3800mAh (which is probably impossible anyhow for AA-sized NiMH cells.
The part about them perhaps not being real NiMH cells? That’s not the weirdest thing. Unlike most of my AliExpress purchases, these shipped from The Netherlands, despite the seller being called Shenzhen DeKang International Trade.

I don't post everything I do, but when I do, I post it here. Maybe.
