Introduction
The CR2025 lithium coin cell (3V) is a high-energy, long-lasting primary battery designed for compact electronic devices requiring reliable and stable power. Compared with smaller CR2016 cells, it offers higher capacity and longer runtime, while maintaining the same 3V stable output and compact diameter.
Built with lithium anode and manganese dioxide cathode, it features low self-discharge (<1% per year), excellent temperature tolerance (-20°C to +60°C), and leak-proof construction. The CR2025 provides up to 170mAh capacity, making it ideal for car remotes, medical instruments, smart sensors, watches, and backup memory systems.
Unlike rechargeable Li-ion or Ni-MH cells, it is maintenance-free, non-rechargeable, and designed for ultra-low drain, long-duration applications. Certified by ROHS, CE, and MSDS, the CR2025 ensures stable voltage, long shelf life (over 8 years), and consistent safety performance superior to conventional alkaline coin cells.
