“14500 battery” refers specifically to the cell’s physical dimensions, where 14 represents the 14mm diameter and 500 indicates the 50.0mm length, mirroring the familiar AA form factor. Unlike standard 1.5V alkaline AA batteries, the 14500 is a lithium-ion chemistry typically boasting a nominal voltage of 3.6V or 3.7V.
When configured into battery packs, 14500 cells offer a unique advantage in space-to-power efficiency, allowing for extremely slim and lightweight designs without sacrificing the rechargeability of lithium-ion technology.
These packs are characterized by their high energy density and stable discharge platforms, often featuring integrated Protection Circuit Modules (PCMs) to prevent overcharging and deep discharge.
Their cylindrical stability makes them highly resistant to external pressure, ensuring a long cycle life and reliable performance in both series and parallel configurations.
The 14500 battery is the preferred power source for high-intensity LED tactical flashlights, portable medical devices, and professional-grade wireless sensors where a compact footprint is mandatory.
Beyond consumer electronics, these cells are widely used in RC hobbyist equipment, electric toothbrushes, and specialized industrial meters that require the higher voltage threshold of lithium to operate precision internal components.
We utilize top-tier A-grade cells with low internal resistance to maximize power delivery, and our sophisticated BMS (Battery Management System) integration provides comprehensive safety and communication protocols. By choosing our custom services, you benefit from rigorous quality control, optimized thermal management, and a streamlined assembly process that significantly reduces your time-to-market for high-performance portable products.
