Description
These GP CR1620 lithium button cells give you a reliable 3V supply in a compact coin format. Each cell measures 16.0mm across and 2.0mm thick, with a rated capacity of 78mAh. Lithium chemistry holds its charge well over long periods, so these are a good fit for jobs where the battery sits in place for months or years at a time.
The CR1620 suits most everyday low-drain uses, including clocks, calculators, car alarm remote controls (also called key fobs) and back up batteries for memory and settings. If your device takes a CR1620 button cell, sometimes labelled a coin cell in the US, these will drop straight in. We supply them in a pack of five, which covers a few spares alongside the one you need right now.
Button cells are worth keeping to hand because they turn up in so many small devices, and they tend to fail at inconvenient moments. Having a five pack in a drawer means you can swap one out without a trip to the shops. Store them somewhere cool and dry, keep them away from young children and pets, and recycle spent cells at a battery collection point rather than putting them in general waste.

Frequently Asked
What voltage is the CR1620?
Each CR1620 cell gives a nominal 3.0V. That figure stays steady through most of the battery's working life thanks to the lithium chemistry.
What size is a CR1620 cell?
It measures 16.0mm in diameter and 2.0mm thick. The name itself reflects this: 16 for the diameter and 20 for the height in tenths of a millimetre.
What can I use these batteries for?
They suit low-drain devices such as clocks, calculators, car alarm remotes and back up batteries for retaining memory or settings.
How many cells come in a pack?
You get five CR1620 cells per pack, giving you a spare or two on top of the one you need to fit now.
Is a CR1620 the same as a coin cell?
Yes. Button cell is the common UK term, while coin cell is used more in the US. Both refer to this flat, round battery format.
How should I dispose of used cells?
Take spent button cells to a battery recycling point. Avoid placing them in general household waste, and keep them away from children and pets.
