Introduction
The CR2016 lithium coin cell (3V) is a compact, high-energy primary battery designed for precision electronics requiring long-lasting and stable power. Compared with alkaline button cells, it delivers higher voltage (3V), superior energy density, and excellent performance in extreme temperatures.
Constructed with lithium anode and manganese dioxide cathode, it ensures low self-discharge, stable voltage output, and shelf life exceeding 8 years. The CR2016 is ideal for watches, car keys, calculators, medical sensors, and IoT devices, where reliability and compact size are critical.
Unlike rechargeable Ni-MH or Li-ion cells, it provides maintenance-free operation, leak-proof safety, and steady power throughout its lifespan. Certified to ROHS, CE, and MSDS, the CR2016 coin cell offers precise, durable, and consistent energy for small electronic systems.
