【Product Description】
The Future of AA Batteries is Here. The NITECORE NH2400 is a revolutionary 1.5V rechargeable AA battery that eliminates the need for a traditional battery charger. Featuring a built-in USB-C port directly on the battery, you can simply plug in a cable and charge it anywhere—at home, in the car, or with a power bank.
Powered by advanced Li-ion technology, the NH2400 delivers a massive 2400mAh capacity and maintains a constant 1.5V output throughout its entire discharge cycle, ensuring your smart locks, cameras, and high-drain devices operate flawlessly without the voltage drop that plagues standard NiMH batteries.
What sets it apart is the Patented Natural Discharge Curve. Unlike typical 1.5V Li-ion batteries that experience a sharp voltage drop at the beginning of use, the NH2400 provides a smooth, linear decrease in voltage. This unique engineering feature ensures more stable, efficient, and long-lasting power delivery compared to standard alkaline or other 1.5V lithium batteries.
Go green and save money. With over 500 recharge cycles, one NH2400 replaces 500 single-use disposable AA batteries.
( IMPORTANT: These are 1.5V Li-ion batteries, NOT 1.2V NiMH. Please ONLY charge them via the built-in USB-C port. Do NOT use a standard NiMH charger.)

【Frequently Asked Questions (FAQ)】
Q1: Does this battery require an external charger?
A1: NO. The NITECORE NH2400 features a built-in USB-C port on its positive terminal. You can recharge it directly using any standard USB-C cable connected to a wall adapter, power bank, or laptop. The 4-pack includes a 4-in-1 cable for simultaneous charging.
Q2: What is the “Patented Natural Discharge Curve”?
A2: Unlike standard 1.5V Li-ion batteries that drop voltage sharply at the start, this battery features a patented design that ensures a smooth, linear voltage decline. This means your devices stay operating stably for a longer period.
Q3: How do I know when it is fully charged?
A3: The battery has a built-in LED indicator. A red light means it is charging, and a green light indicates that it is fully charged and ready to use.
Q4: Can I charge these batteries with my NiMH charger?
A4: NO! Do not use a NiMH charger. These are 1.5V Li-ion batteries. Using a NiMH charger (which is designed for 1.2V cells) could damage the battery. Please charge them exclusively via the built-in USB-C port.
Q5: Is there a difference between 1, 2, and 4 packs?
A5: Yes. The 1-pack is for a single battery replacement. The 2-pack is for a pair of batteries. The 4-pack is the best value, as it includes a premium 4-in-1 splitter cable, allowing you to charge all four batteries at the same time in just 3 hours.
