The Giga-Tek CR2025 3V Lithium Coin Battery delivers consistent and reliable power for small electronic devices. Built with Lithium Manganese Dioxide (Li-MnO₂) chemistry, it ensures a stable 3V output and low self-discharge, maintaining more than 90% of stored energy after years of storage.

With a diameter of 20mm and a thickness of 2.5mm, the CR2025 is slightly slimmer than the CR2032, making it suitable for space-constrained electronics. It features leak-proof construction, safe operation across a wide temperature range (-20°C to +70°C), and strong pulse discharge capability for remote-control applications.

Trusted under the Giga-Tek brand, this coin cell is widely used in IoT devices, fitness trackers, watches, calculators, digital thermometers, medical equipment, and memory backup systems.
