Description
The JCB CR2025 is a 3V lithium coin cell battery measuring 20mm in diameter and 2.5mm thick, designed for watches, car key fobs, calculators, fitness trackers, medical devices and small electronics requiring compact power. The lithium chemistry provides stable voltage across the discharge curve, maintaining consistent device performance until the cell is depleted.
Single-cell CR2025 batteries suit devices with intermittent low-draw power requirements rather than continuous high-drain applications. Typical use cases include CMOS backup power in motherboards, real-time clock circuits, wireless door sensors, laser pointers and LED keyring lights. The 3V output matches the requirements of most CR2025-specified devices without needing voltage regulation.
JCB lithium cells carry an extended shelf life of several years when stored at room temperature, making them suitable for spare stock in toolkits, emergency kits and maintenance supplies. The leak-resistant seal prevents corrosion of device contacts during storage and use. The battery ships in blister-pack retail packaging with a single cell per pack.

Frequently Asked
What devices use CR2025 batteries?
CR2025 cells power watches, car key fobs, calculators, fitness trackers, motherboard CMOS circuits, wireless door sensors, medical glucose monitors, laser pointers and LED keyring lights. Any device marked CR2025 on the battery compartment or manual accepts this cell size.
Can I use CR2025 instead of CR2032?
No. Both are 3V lithium and 20mm diameter, but CR2032 is 3.2mm thick while CR2025 is 2.5mm thick. A CR2025 will not make contact in a CR2032 compartment, and forcing a CR2032 into a CR2025 slot can damage the device.
How long does the battery last?
Runtime depends on device current draw. In a watch or calculator with intermittent low draw, a CR2025 typically lasts 2-3 years. In higher-draw devices like fitness trackers or wireless sensors, expect 6-12 months.
What is the shelf life?
JCB lithium coin cells carry a shelf life of several years when stored at room temperature in the original blister pack. Check the date code on the packaging for the specific expiry.
