A 16340 battery is a rechargeable lithium-ion cell designed for compact, high-drain applications. With standard dimensions of 16mm x 34mm, it serves as a rechargeable alternative to CR123A batteries while delivering a higher voltage (3.6V – 3.7V nominal). These cells are widely used in tactical flashlights, medical instruments, security devices, and industrial electronics.
Technical Specifications
Voltage:3.6V – 3.7V nominal, full charge at 4.2V, and discharge cutoff of 2.5V – 3.0V.
Capacity Range: Typically between 600mAh and 1200mAh, depending on chemistry and application.
Battery Chemistry Types:
Lithium Cobalt Oxide (LiCoO₂ - LCO): Maximized energy storage for extended runtime.
Lithium Iron Phosphate (LiFePO₄ - LFP): Exceptional cycle life and ultra-safe operation, but nominal voltage is 3.2V instead of 3.7V.
Discharge Rate (CDR): Some high-drain 16340 cells offer continuous discharge rates of 3A – 10A, making them ideal for power-intensive devices.
Cycle Life: Can last 500 to over 1000 charge cycles, depending on proper maintenance and chemistry type.
Protected vs. Unprotected 16340 Cells
Protected 16340 Batteries: Feature an integrated protection circuit to safeguard against overvoltage, deep discharge, and short circuits.
Unprotected 16340 Batteries: Preferred for battery packs or regulated devices that incorporate built-in battery management.
Industry Applications for 16340 Batteries
✔ Professional & Tactical Flashlights: Used in high-output LED flashlights requiring CR123A-sized lithium-ion cells. ✔ Medical & Industrial Equipment: Found in portable monitoring devices, sensors, and precision measurement tools. ✔ Security & Surveillance Systems: Powers infrared (IR) cameras, motion detectors, and biometric scanners. ✔ Tactical & Military Gear: Used in laser sights, night vision devices, and weapon-mounted optics.
Choosing the Right 16340 Battery
🔹 Voltage Compatibility: Verify that your device supports 3.6V or 3.7V instead of standard 3.0V CR123A batteries. 🔹 High-Drain vs. Standard Cells: Devices requiring rapid power output should use high-CDR 16340 cells. 🔹 Button Top vs. Flat Top: Check your device’s battery compartment to ensure proper fitment.
