This AmazonBasics batteries come with 2500 mAh 1.22 V with me, even though it was not so long in the trade are. These are the values that have the AmazonBasics batteries with 2000 mAh. But these are only 500 times can be loaded. The normal Eneloop AA batteries have been all 1,32- 1,33 V, when you arrive at me. Have been about 90 Enloop AA and AAA Eneloop 120 bought and whenever batteries are supplied, fair and I invite you once with my MEC-Energietechnik AV4m Battery Charger coach and IVT Battery trainer AT-3 + chargers, modified by Fritz Mössinger (ACCU Selekt), which has also provided a page with a lot of useful information about batteries, chargers and battery technology into the net. Just google, is certainly worthwhile. After loading with these chargers the Amazon Basic batteries reach approximately 10% less capacity than the normal Eneloop, opposite the Eneloop XX even less. The indicated values are, from the batteries I have received, not complied with; if they were significantly cheaper, they would be an alternative to the simple Eneloop that are partially effective even, unfortunately, not so; Too Bad !! Only the exterior is quite pleasant. Compared to the normal AmazonBasics batteries the Ummantlung is matt black and feels more comfortable.
