Description

Technical Excellence & Cell Architecture

As global demand for miniaturized power solutions surges in 2026, the 3.7V 800mAh ICR14500 remains a cornerstone of the cylindrical battery market. Although it shares the same physical dimensions as a standard AA battery (14mm X 50mm), it delivers more than double the voltage of NiMH or alkaline alternatives.

  • Cell Chemistry: Lithium Cobalt Oxide (LiCoO2), optimized for high energy density.
  • Nominal Specifications: 3.7V nominal voltage with a robust 800mAh rated capacity.
  • Charge/Discharge Cycle: Capable of 500+ deep cycles while maintaining significant capacity retention.
  • Modular Versatility: The 3.7V 800mAh ICR14500 is frequently utilized in Series (S) and Parallel (P) configurations to meet specific industrial requirements:
  • 7.4V (2S1P): Standard for portable handheld scanners and wireless intercoms.
  • 11.1V (3S1P): Ideal for medical diagnostic equipment and beauty devices.
  • 14.8V (4S1P): High-power configuration for specialized lighting and robotics.

Comprehensive Application Scenarios

The lightweight design and reliable discharge profile of the 3.7V 800mAh ICR14500 make it indispensable across multiple sectors:

  • Professional Lighting: High-output LED flashlights and tactical headlamps where sustained brightness is critical.
  • Smart Home & IoT: Powering wireless door sensors, smart locks, and environmental temperature monitors.
  • Personal Care: Providing long-lasting energy for electric toothbrushes, shavers, and massagers.
  • Hobby & RC: Used in lightweight remote-controlled toys, drones, and model aircraft.
  • Industrial Instruments: Powering digital cameras, portable measurement tools, and laser pointers.
