Yes I’m a bit disappointed as I was hoping they would have an appreciably higher capacity than the energizer recharge power plus I bought a week or two ago. See tests on them here:
On the other hand they seem very similar to the eneloops as tested by HKJ (see below). His results for the “Eneloop AAA HR-4UTGB 750mAh (White)” show 724 mah at a 200 ma discharge and 714 mah at a 500 ma discharge. The eneloops are rated at a capacity between 750 and 800 mah.
I’ve just finished a 1000 ma discharge test on 4 of the 8 batteries (amazonbasics white aaa’s):
716, 719, 720, and 732 mah - average is 721.75 mah.
HKJ’s results for the eneloops show 706 mah at a 1000 ma discharge. So it appears that these are quite comparable.
This isn’t really related however might be of interest:
I did a 500 ma discharge of some older but moderately used Duraloop aaa’s and got the following results:
704, 713, 717 and 722 mah - average is 714 mah.
(edit note: I charged these first then left them several hours before doing the discharge)
Conclusions:
The amazonbasics aaa’s (white) that I recently purchased are very similar in capacity and ability to discharge as the eneloops tested by HKJ in the thread noted above. I won’t know about their LSD ability until they have been sitting for some time and I doubt I’ll do that as I need to put the batteries to use soon. Without a lot more testing I can’t be sure that they are or are not made in the same factory to the same specs as the eneloops but at this point I’m not very concerned about that. In their own right they are quite decent batteries and should be well up to any application I use them for.
One thing to keep in mind is that Amazon may change suppliers or specs without making big changes to the appearance of the batteries and descriptions. For example Duracell did this some time ago in that some of their LSD cells were changed from being made in Japan to being made in China (white vs black top). Buyer beware!
One further test I will perform (it still bothers me that these cells are showing lower than advertised capacity) is use my hobby charger to discharge a couple of them down to .9 volts at a 200 ma discharge. I have to test them one at a time and it will take a few hours each so the results won’t be available till late today.
I will also post a summary table of the results noted in the previous posts.
Great information! I think I will go for it. A lot of my cells are pretty old, maybe relegate them to kids toys.
Just need to find stuff to make the $25 free shipping (trying to resist another Thrunite. With the exchange their are a few great deals!).
Gunga - glad to be of service. Shipping was about $3.50 or so since I didn’t have enough to get free shipping. For anything in Canada that’s very reasonable.
Are you using an Accucel 6 or a clone of it? Mine understates discharge capacity by 8% - 10% (as compared to my Opus). Others have reported the same issue with their hobby chargers.
I’m using a clone (Thunder ac6 dual power) but all of the discharge tests of the amazonbasics aaa’s (white) that I’ve done to date have been done on my maha mh-c9000. The 200 ma test to 0.9 V will be done with the Thunder since the maha only takes them down to about 1.0 volts.
It’s true that the opus could be off but the Accucel was returning unbelievable numbers with more than 20 new AA Eneloops charged on multiple chargers. Most were in the 1600 to 1700 mah range. New Panasonic 18650B’s were also reading below 3000 mah fresh off my xtar xp2, nitecore i2, and miller ml102.
5. if the batteries are indeed 2nd gen eneloops, it means they are a few years old. In that case they are more likely to perform a bit better after some use.
(although they say they are manufactured in 2014, which would mean they are 4th gen)
the specs say 70% after 3 years...
thats lower than eneloop claimed with their 2nd gen.. 75%after 3 years.
we know that the manufacturers also don`t use the same numbers, so take them for what you think they are worth
This topic came about at he right time.
I just placed an order for some amazonbasic AAA as well, should get them next week.
I will test them as well and post my results.
These results don’t make a lot of sense to me except to doubt the accuracy of the Thunder hobby charger. I tested two cells at 200 ma down to .9 volts (done separately) and the results were 663 and 704 mah.
Thanks for the information ChibiM and SigShooter. It will be interesting to see HKJ’s upcoming review.
Based on your narration above, it looks that you performed a discharge test ‘out of the box’? If so, then that 70% capacity is spot-on as they are charged to about 70% when ready to be sold at the shelves.

Don’t know. Fujitsu, maybe? I’ll wait until HKJ runs the Amazon batteries through his tests before I get too excited. As I said, the price of the Amazon ones isn’t exactly bargain basement - even when they are available as lightning deals (which is often).
