NITECORE NH2400 Rechargeable Li-ion AA Battery 2-Pack | 1.5V Constant Output, USB-C Charging, 2400mWh

Experience unwavering 1.5V power with the NITECORE NH2400 rechargeable lithium-ion AA batteries. Each cell delivers a constant voltage output, eliminating the performance drop common in NiMH batteries and ensuring your devices run at full capacity until completely depleted.

Overview

The NH2400 is a true 1.5V constant-voltage lithium-ion AA battery. Unlike traditional rechargeable NiMH batteries that start at 1.2V and drop as they discharge, the NH2400 maintains a steady 1.5V throughout its entire discharge cycle. This means your devices receive full power until the battery is completely depleted, preventing performance issues like dimming flashlights or sluggish motors. The battery's 2400mWh energy capacity is equivalent to approximately 1600mAh at 1.5V, providing reliable runtime for everyday electronics.

What stands out

• Constant 1.5V output for consistent device performance
• Built-in USB-C charging port on each battery—no separate charger needed
• LED charging indicator: red while charging, green when complete
• Over 500 charge cycles for long-term savings and reduced waste
• Comprehensive protection circuit: overcharge, over-discharge, short-circuit, over-current, over-voltage
