NEW! Eneloop Pro 2HR Charger Kit

with 4pc Pro AA Battery

Overall, the best rechargeable AA battery is the Eneloop Pro.
They have a high energy capacity (2500 mAh), and they perform better than similar high-capacity AAs.
They can only be charged 500 times (versus 2100 times for regular Eneloops). But most people will never charge their batteries that many times.
For example, if you charged your batteries twice a week consistently, it would take 5 years to reach 500 charges.
