14500 Batteries | Reliable Rechargeable Lithium-Ion Cells

A 14500 battery is a lithium-ion rechargeable cell with the same dimensions as a standard AA battery (14mm x 50mm) but delivers a significantly higher voltage (3.6V or 3.7V nominal). Designed for compact, high-efficiency power applications, 14500 cells are commonly used in tactical flashlights, medical equipment, wireless sensors, and industrial electronics.

Technical Specifications

• Voltage: 3.6V – 3.7V nominal, with a full charge voltage of 4.2V and a discharge cutoff of 2.5V – 3.0V.

• Capacity Range: Typically between 600mAh and 1200mAh, depending on chemistry and discharge rating.

• Battery Chemistry Types:

  • Lithium Cobalt Oxide (LiCoO₂ - LCO): Maximized energy storage with moderate discharge rates.
  • Lithium Manganese Oxide (LiMn₂O₄ - LMO): Enhanced thermal stability and safer performance.
  • 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): Certain high-drain 14500 cells offer discharge rates of 3A – 10A, suitable for demanding applications.

• Cycle Life: Can exceed 500 to 1000+ charge cycles, depending on proper maintenance and chemistry type.

Protected vs. Unprotected 14500 Cells

• Protected 14500 Batteries: Feature an integrated protection circuit to safeguard against overvoltage, deep discharge, and short circuits.
• Unprotected 14500 Batteries: Preferred for battery packs or regulated devices with built-in safety management.

Industry Applications for 14500 Batteries

✔ Professional & Tactical Flashlights: Used in high-output LED flashlights requiring AA-sized lithium-ion cells.
✔ Industrial & Medical Equipment: Found in portable monitoring devices, sensors, and IoT electronics.
✔ Smart Home & Security Systems: Powers motion detectors, wireless alarms, and surveillance cameras.
✔ Custom Battery Packs & Robotics: Integrated into specialized battery packs for low-power robotics and automation.

Choosing the Right 14500 Battery

When selecting a 14500 cell, consider:
🔹 Voltage Compatibility: Ensure your device supports 3.6V or 3.7V instead of a standard 1.5V AA battery.
🔹 High-Drain vs. Standard Cells: Devices requiring rapid power output should use high-CDR 14500 cells.
🔹 Button Top vs. Flat Top: Verify battery compatibility based on terminal type.
