3.7V Lithium Battery Manufacturer
What is a 3.7V Lithium Battery?
A 3.7V lithium battery is a single-cell rechargeable battery that uses lithium-ion or lithium-polymer chemistry. Known for its high energy density, lightweight structure, and stable discharge platform, 3.7V batteries are widely used in compact, portable, and high-efficiency power systems. Common applications include consumer electronics, wearable devices, handheld instruments, drones, and medical equipment. For OEMs, device manufacturers, and solution integrators, 3.7V lithium batteries offer a reliable and scalable energy source for a broad range of industrial and commercial projects.
Lightweight, Efficient, and Versatile Power
3.7V lithium batteries are ideal for projects requiring compact design and long runtime. Compared to older battery technologies, they deliver higher voltage per cell, enabling simpler battery pack configurations and reduced space consumption. These batteries provide fast charging, low self-discharge, and steady voltage output throughout the cycle, ensuring efficient performance even under varying loads. With an average lifespan of 500–1000+ cycles, they are especially suited for products that demand consistent operation with minimal maintenance.
