Description
Product Description:
Experience superior performance and safety with the Keeppower 16340 1000mAh 3.7V Protected Button Top Battery (Model: KP P1634C3). This premium protected Li-ion cell delivers an impressive 1000mAh high capacity and a steady 2A continuous discharge current, making it the ultimate power source for high-performance tactical flashlights, headlamps, and outdoor gear.
Unlike standard bare cells, the KP P1634C3 features a built-in Protection Circuit Board (PCB) that offers smart protection against overcharging, over-discharging, and short circuits. Its Button Top design ensures a secure and reliable connection with spring-loaded battery compartments. Whether you are upgrading your EDC flashlight or replacing your old CR123A batteries, this Keeppower cell delivers reliable, long-lasting power.
CRITICAL INSTALLATION WARNINGS:
-
Size Alert: This battery measures 16.8mm (Diameter) x 35.8mm (Height). Due to its high capacity and PCB, it is slightly longer than standard 16340 batteries (34mm). Please verify your device's battery compartment depth can accommodate 35.8mm before ordering.
-
Voltage Compatibility (CR123A Replacement): This is a 3.7V battery (fully charged to 4.2V). It is a popular replacement for 3V CR123A batteries in most modern tactical flashlights. However, please verify your device supports 3.7V input before use. Using a 3.7V battery in a device strictly designed for 3V may cause overheating.
Key Features:
High Capacity 1000mAh with 2A Output: Offers significantly longer runtime compared to standard 800-900mAh 16340 cells, delivering stable 2A continuous power.
Built-in PCB Protection: Integrated smart circuit provides absolute safety against overcharge, over-discharge, and short circuits.
Button Top Design: The raised positive terminal ensures stable contact with spring-based battery connectors in flashlights and optics.
Genuine Keeppower Quality (KP P1634C3): Reliable branded cell with a standard 500+ recharge cycle lifespan.
Versatile Replacement: An excellent alternative to 3V CR123A disposable batteries (please check voltage compatibility).

FAQ:
Q: Is this battery protected?
A: Yes. It has a built-in Protection Circuit Board (PCB), so you don't need to worry about overcharging or overdischarging your device.
Q: Why is this battery 35.8mm tall instead of the standard 34mm?
A: The extra length comes from the built-in Protection Circuit Board (PCB) and the high-capacity 1000mAh cell. It is normal for protected 16340 batteries to be slightly longer. Please ensure your flashlight compartment can accommodate this extra length.
Q: Can I use this to replace my CR123A battery?
A: Please check carefully. This is a 3.7V rechargeable battery. Most modern tactical flashlights can handle 3.7V (4.2V max). However, if your device is strictly designed for 3V CR123A batteries, using this battery might damage your device. Please confirm your device's max voltage rating before purchasing.
Q: How long does it take to fully charge?
A: Using the recommended 200mA standard charger, it will take approximately 6 hours to fully charge this 1000mAh battery.
Q: Is it compatible with standard 16340 chargers?
A: Yes, it is compatible with most standard 3.7V / 4.2V Li-ion battery chargers designed for 16340/18350/18650 sizes.
