Customer Reviews

I just finished testing one set of those AmazonBasics AA NiMH Pre-Charged Rechargeable Batteries, using my old La Crosse BC-900 Charger/Analyzer. Here are my findings:
- Right out of the box, their average remaining charge is 1946mAh. The spread is very small, ranging from 1933 to 1959mAh. Note that the date code on those cells says 'MAR2011', so they probably left factory just two months ago. Still, those numbers are really impressive.
- After just one recharge/discharge cycle (done at 700/350mA), the average capacity improved to 2217mAh. That is about 11% higher than the rated capacity of '2000mAh'. Again the spread is small, varying from 2200 to 2250mAh. Those numbers remain unchanged in subsequent recharge/discharge cycles.
It is interesting to note that: performances of those AmazonBasics Pre-Charged AA cells are nearly identical to that of GP ReCyko AA cells, which I have tested last November. So I won't be surprised if those 'AmazonBasics' cells turn out to be rebranded GP ReCyko.
Just for comparison, the NEW Sanyo eneloop AA cells are also rated for 2000mAh typical, but the average capacity I measured is around 2130mAh, or 'only' 6% higher than rated. On the other hand, Sanyo claims the second-generation eneloop cells can be recharged up to 1500 cycles, whereas GP and AmazonBaisc NiMH batteries are rated for 'only' 1000 cycles. In real life, most people will probably never notice the difference.
In summary, all three brands I mentioned above (Sanyo, GP and AmazonBasics) are excellent products. They all live up to the claim of "pre-charged and ready to use right out of the pack", and offer even higher capacities than rated. So just go by which brand is on sale, and you can't go wrong.
[Aside]
Most battery makers are touting their products as 'Advanced', 'Platinum', 'Ultra', and so on. Why oh why does Amazon simply call those superior batteries 'AmazonBasics'? If this is 'Basic', I can't wait to test the 'AmazonPrime' batteries!
[Aside2]
Those AmazonBasics Pre-charged NiMH batteries are in black, which (to me) makes them look like disposable alkaline cells. On the other hand, the AmazonBasics Alkaline Batteries are in white, which makes them look like rechargeable cells. I really wish the color scheme were the other way around.
[Update on Apr 14, 2012]
Long term self-discharge data of AmazonBasics batteries were disappointing, so I have to downgrade my rating from 5 to 4 stars.
I tested one pair each of thos AA cells after 3, 4 and 8 months of storage. The average remaining charge measured were 82.3%, 79.4% and 67.6% respectively. That means they have already failed the claim of "maintains 80% of capacity after 1 year". If the present linear trend (-3% per month) continues, I expect them to retain only 55% of original charge after one year. In contrast, my previous test data with Sanyo eneloop and GP Recyko+ showed that they can retain at least 80% after 12 months.
New bottom line: For most applications, those AmazonBasics cells are good enough. But for mission-critical applications, I have to recommend Sanyo eneloop instead.

With all the pre-charged batteries from different manufacturers out there now, there is no need for 1-time use alkaline batteries anymore.
Using my Lacrosee BC-700 battery charge/test function, the 4 "AAA" batteries performed as follows:
Battery 1 = 846 mAh
Battery 2 = 874 mAh
Battery 3 = 876 mAh
Battery 4 = 860 mAh
(See picture on customers' submitted images)
Straight from the box, the batteries show remaining voltages between 1.31 to 1.32 volts (see pic above). All packs more juice compared to its rated capacity of 800 mAh. Comparable to the capacities of Eneloops and Duracell.
I have been using pre-charged batteries for everything now, from toys, digital cameras, clocks, to remote controls.
