From the shape and the technical specifications the Amazon batteries eneloop an older type are very similar.
On delivery the charge state was still high - I had previously only at eneloop.
For testing purposes, I have the batteries are fully charged and discharged a few times and then determines the capacity.
The AAA I came to 820-830 mAh (nominal 750 mAh).
When I arrived at the AA 2020 - 2040 mAh (nominal 1900 mAh).
These are also values that are typical for eneloop.
For all other producers incl. High-priced NiMH batteries, the actual capacity was always below the nominal value and the self-discharge rate was much higher.
Statements regarding the durability I can not do - but because the eneloops are fantastic - I hope the AmazonBasics.
Conclusion:
Either is eneloops or a very similar type. Am very happy and will buy me some more of them.
