14500 Batteries | Compact Lithium-Ion Power Solutions

A 14500 battery is a rechargeable lithium-ion (Li-ion) cell that shares the same size as a standard AA battery (14mm in diameter and 50mm in length) but operates at a higher voltage (3.6V or 3.7V). Due to their compact size, high energy density, and rechargeable nature, 14500 batteries are widely used in flashlights, RC toys, medical devices, and other portable electronics.

Key Features & Specifications

• Voltage: Typically 3.6V or 3.7V nominal, with a fully charged voltage of 4.2V and a cutoff around 2.5V – 3.0V.
• Capacity: Ranges from 600mAh to 1200mAh, depending on the chemistry and manufacturer.
• Chemistry Options:
  • Lithium Cobalt Oxide (LiCoO₂ - LCO): High energy density for long-lasting performance.
  • Lithium Manganese Oxide (LiMn₂O₄ - LMO): Safer with better heat resistance.
  • Lithium Iron Phosphate (LiFePO₄ - LFP): Superior cycle life and safety but operates at 3.2V nominal instead of 3.7V.

Protected vs. Unprotected 14500 Batteries

• Protected 14500 Batteries: Include a built-in protection circuit to prevent overcharging, over-discharging, and short circuits. These are slightly longer than standard cells.
• Unprotected 14500 Batteries: Used in devices that already have built-in battery protection and require direct power output.

Common Applications for 14500 Batteries

14500 batteries are commonly found in:
✔ Flashlights & LED Devices: High-powered AA-sized flashlights that require more energy than standard alkaline batteries.
✔ RC Toys & Hobby Electronics: Rechargeable power source for remote-controlled cars, drones, and other hobby gadgets.
✔ Medical & Industrial Equipment: Used in portable diagnostic tools, sensors, and precision instruments.
✔ Smart Home Devices & Cameras: Found in wireless security cameras, digital thermometers, and motion sensors.

Choosing the Right 14500 Battery

Before purchasing, ensure compatibility by checking:
📌 Voltage Requirements: 14500 batteries operate at 3.6V or 3.7V, whereas standard AA batteries are only 1.5V.
📌 Protected vs. Unprotected: If your device lacks built-in protection, opt for a protected cell.
📌 Button Top vs. Flat Top: Some devices require a button top, while others use flat top cells.
