Amazon Basics 4-Pack Rechargeable AA NiMH High-Capacity Batteries, 2400 mAh, 1.2V, Recharge up to 400x Times, Pre-Charged

Customers find these rechargeable batteries work well and offer good value for money, particularly for wireless keyboards and mice, with one customer noting they outperform smaller-capacity types. The batteries come pre-charged and have high capacity, though some report they stop holding a charge after a year. They are slightly larger than regular AA batteries, making them difficult to fit in certain devices like flashlights and Xbox 360 controllers.
