The Best Rechargeable AA and AAA Batteries

Regardless of whether you pop them into a wireless mouse, a toy, or a flashlight, rechargeable AA and AAA batteries almost always last longer, cost less, and result in less waste than their disposable counterparts. After 10 hours of research and thousands of hours of testing, we found that many rechargeable batteries perform about the same. Most are made in China, Japan, or South Korea and contain roughly the same components. So it was unsurprising that several models—including AAs and AAAs from EBL, AAs and AAAs from HiQuick, and AAs and AAAs from Tenergy—had nearly identical results in our tests. When you need to stock up, we recommend getting whichever of our top picks is the least expensive.
