Description
These GP CR2430 lithium button cells give you a steady 3.0V from a compact coin form, with a 270mAh capacity that keeps small devices running for a long time. Supplied in a pack of five, they are ready to drop into a wide range of everyday items around the home, workshop or car.
We find these cells suit most common jobs, including clocks, calculators, remote controls for car alarms and back up power for memory and settings. The lithium chemistry holds its charge well over time, so a cell fitted as a backup will still be there when you need it. Each battery measures 24.5mm in diameter and 3.0mm in height, matching the standard CR2430 size so it fits any holder built for that type.
Button cells are also called coin cells, and both terms describe the same flat round battery you see here. When you replace one, check the CR2430 marking on the old cell to make sure you have the right fit, since coin cells come in several close sizes. Handle them with clean, dry hands, keep spares in their pack until needed, and store any loose cells safely away from children and pets.
