Nitecore’s NH2400 High-Performance Rechargeable AA Battery pack includes four 2400mAh USB-C rechargeable batteries, a 4-split charging cable, and a storage case. Compatible with standard AA devices, these batteries provide stable output and extended runtime, ideal for high-drain devices such as flashlights. With a higher capacity than typical NiMH or alkaline AA batteries, the NH2400 reduces the frequency of recharging and battery replacements.
