Description
This GP CR2450 is a 3V lithium button cell that suits a wide spread of everyday devices. With a capacity of 610mAh, it keeps small electronics running for a long time between changes, which makes it a practical choice for things you don't want to open up too often. It's a single cell, so you can buy just what you need for a one-off replacement or keep a spare on hand.
You'll find the CR2450 works well in clocks, calculators, remote controls for car alarms and as a backup battery in devices that need to hold settings when the mains power drops. Lithium chemistry gives a steady 3.0V output and a long shelf life, so a cell stored in a drawer will still be ready when you reach for it. The coin shape, sometimes called a button cell or coin cell, fits flush into slim battery compartments.
The cell measures 24.5mm across and 5.0mm thick, which is the standard CR2450 size and means it drops straight into any device built for that format. Check the marking on your old battery or in the device manual to confirm you need a CR2450 rather than a similar-looking coin cell, as the sizes are close but not interchangeable. Once fitted, the correct cell will sit securely and make good contact for reliable running.
