Today, the best rechargeable batteries are the “low self-discharge” Nickel-Metal Hydride (Ni-MH) cells. These Powerex are also low-discharge, high-capacity batteries ( 2400 mAh), but they do not perform quite as well as the Eneloop Pro (see this review for the details on their performance). For example, if you charged your batteries twice a week consistently, it would take 5 years to reach 500 charges.Īlso worthy of consideration is the Powerex battery, which is cheaper than the Eneloop Pro. But most people will never charge their batteries that many times. They can only be charged 500 times (versus 2100 times for regular Eneloops). They have a high energy capacity (2550 mAh), and they perform better than similar high-capacity AAs. Overall, the best rechargeable AA battery is the Eneloop Pro. If you are on a budget don’t mind a little less performance from your batteries - get the Powerex AAs (about $10 for pack of 4).If you want maximum recharge capacity (2100 times) - get the 4th Generation Panasonic Eneloops (about $11 for pack of 4).


Here are my recommendations for the best rechargeable AA batteries:
