A 16340 battery is a rechargeable lithium-ion (Li-ion) cell that shares similar dimensions to a CR123A battery but operates at a higher voltage. Measuring 16mm in diameter and 34mm in length, these compact, high-energy batteries are widely used in flashlights, cameras, medical devices, and other portable electronics that require reliable and rechargeable power.
Key Features & Specifications
Voltage: Typically 3.6V or 3.7V nominal, with a full charge voltage of 4.2V and a cutoff around 2.5V – 3.0V.
Capacity: Usually ranges from 600mAh to 1200mAh, depending on the chemistry and brand.
Battery Chemistry Options:
Lithium Cobalt Oxide (LiCoO₂ - LCO): High energy storage for long-lasting runtime.
Lithium Iron Phosphate (LiFePO₄ - LFP): Superior cycle life and safety, but operates at 3.2V nominal instead of 3.7V.
Protected vs. Unprotected 16340 Batteries
Protected 16340 Batteries: Feature a built-in protection circuit to prevent overcharging, over-discharging, and short circuits. These are slightly longer than standard cells.
Unprotected 16340 Batteries: Used in devices that already have built-in battery protection or require direct power output.
Common Applications for 16340 Batteries
16340 batteries are commonly used in: ✔ Flashlights & LED Devices: A rechargeable replacement for CR123A batteries in high-output flashlights. ✔ Cameras & Security Systems: Powers wireless security cameras, motion detectors, and night vision scopes. ✔ Medical & Industrial Equipment: Found in portable diagnostic devices, laser sights, and specialty sensors. ✔ Tactical & Military Gear: Used in infrared (IR) lasers, weapon-mounted flashlights, and optics.
Choosing the Right 16340 Battery
📌 Voltage Compatibility: Ensure your device supports 3.6V or 3.7V instead of a standard 3.0V CR123A battery. 📌 Protected vs. Unprotected: If your device lacks built-in safety mechanisms, opt for a protected cell. 📌 Button Top vs. Flat Top: Some devices require a button top, while others use flat top cells.
