18650 Lithium-Ion Batteries

High Capacity. Stable Power. Trusted Performance.

18650 lithium-ion batteries are engineered to deliver high energy density, reliable output, and long cycle life for a wide range of high-drain and energy-demanding applications. With a standard size of 18 mm × 65 mm, 18650 cells have become one of the most widely used rechargeable battery solutions in modern electronics and energy systems.

Built with advanced lithium-ion chemistry, 18650 batteries provide stable voltage, excellent discharge performance, and high efficiency. They are designed to support continuous and pulse discharge, making them ideal for applications such as power tools, electric bikes, energy storage systems, medical equipment, laptops, LED lighting, and industrial devices.

Each 18650 battery is manufactured under strict quality control standards and incorporates multiple safety protections, including overcharge, over-discharge, short-circuit, and thermal protection (when integrated with a protection circuit). With long cycle life and low self-discharge, these batteries offer reliable performance and extended service life, reducing replacement costs over time.
