10 Best Aa Rechargeable Batteries 2026 in the United States

The Amazon Basics 24-Pack Rechargeable AA NiMH Batteries offer a solid choice for everyday household devices such as remote controls, flashlights, and clocks. Each battery has a capacity of 2000 mAh, which means it can store a decent amount of charge, suitable for moderate power needs. They provide a voltage of 1.2V, standard for NiMH rechargeable batteries, though this is slightly lower than the 1.5V of typical alkaline batteries, so some devices might experience a shorter runtime. These batteries stand out with a long cycle life, as they can be recharged up to 1000 times, which helps save money and reduce waste over time.

A key strength is their low self-discharge rate, maintaining about 80% of their charge after two years in storage, making them reliable if you don’t use them frequently. They come pre-charged and ready to use, which is convenient for immediate use. On the downside, NiMH batteries are slightly larger than alkaline ones, so checking device compatibility is important. Also, the runtime might feel shorter compared to alkaline batteries in some devices.
