If you are looking for affordable batteries that perform just as well as the big names in the industry, buy the
AmazonBasics Rechargeable Batteries (AA and AAA).
With a 2 000mAh capacity (1,900mAh minimum) for AAs and 800 mAh (750mAh minimum), there is little appreciable capacity difference between AmazonBasics Rechargeable Batteries and top names like Duracell, Energizer, and Eneloop.
