AA Rechargeable Batteries – Long-Lasting Double A Batteries, Pre-Charged Household Batteries for All-Purpose Use, Ideal for Home & Business Devices (8-Pack)

Very pleased with the batteries so far. I use them in several remotes so that I don't have to keep replacing standard batteries. Overall, they do what they are advertised to do and seem to hold the charge very well.

Good performance for the money. Have it only for a couple of days so cannot comment on longevity and self-discharge characteristics. Came partially charged. I charged the batteries to full capacities and tested them on a charger/discharger analyzer. The useful capacity (down to 1 Volt) was 2300-2400 mAh with small variations between individual units. This is below the claimed 2800 mAh capacity but it is very competitive with major brands. The diameter of the battery is about 14.4 mm which is typical of NiMH AA batteries. (Alkaline AA batteries are typically narrower, having 14mm diameter) so it may not fit into some tight battery holders.

These batteries shipped quickly and arrived charged. I used them in our solar rechargeable garden path light fixtures. They charge up during the day and run until next morning when the sun shines all day. Following cloudy days they sometimes don't get enough charge. I don't blame this problem on the batteries. We have used them for a few weeks and they are doing a fine job.

De muy buena calidad

Very good price for solar batteriesMy yard lights are working again

It's my fault for not reading the description was looking for 1.5v when these are 1.2

The media could not be loaded. I bought an 8 pack of Kamcy 2800mAh. Professionally tested them in my Opus BT-C3100 at a discharge rate of 500mA which is about C/5.5 and they were verified at 85% of the advertised capacity.If I had had the patience to test at 200mA, which would be about C/14, I have no doubt that they'd meet or exceed the advertised 2800mAh rating. Internal resistance was also low, as low as 82mOhm incl the spring-loaded terminal connection's resistance.

I charged and tested a few times over a full day and it did not seem that these charged fully. They shipped at about 2/3 capacity, but even after all this time I could not get my tester (albeit older technology) to show complete charge. I haven't used the batteries yet in a device, so I can not report about the longevity, but I wanted to charge them up for when I will need them, and discovered that they visibly did not fully charge.
