Duracell Coin and Button Cells
Small coin and button cells power a surprising amount of airsoft kit. Red dots, holographic and reflex sights, lasers, tracer units, chronographs, timers and small torches often rely on a single cell, and when it goes flat your equipment stops working. This collection brings together Duracell coin and button batteries in sizes commonly used in this kind of gear, so you can keep spares in your kit bag.
Sizes in This Collection
- CR1220 – a small 3V lithium coin cell, used in some compact sights, lasers and small electronics.
- CR2016 – a slim 3V lithium coin cell, found in various sights, remotes and gadgets.
- AG10 / LR1130 (pack of 2) – a small alkaline button cell often used in compact electronics, laser pointers and some small lights.
How to Find the Right Battery
Coin cell names follow a simple pattern: for lithium "CR" cells, the first two digits are the diameter in millimetres and the last two give the thickness in tenths of a millimetre. A CR2016, for example, is 20mm across and 1.6mm thick. Cells of the same diameter but a different thickness may fit loosely or not at all, so it's always best to match the code exactly. The easiest way to check is to look at the code printed on the old battery, or in your device's manual. Button cells such as the AG10 are often sold under more than one name (for example LR1130), so check the alternative codes on the product page.
Tips for Getting the Most From Your Cells
- Switch optics and lasers off after use; many have no auto shut-off.
- Carry a spare cell in a small pouch or your optic's battery compartment cap, if it has one.
- Store spare cells in their packaging, away from metal objects like keys and coins that can short them.
- Keep batteries out of reach of children and pets; small coin cells are a swallowing hazard.
- Remove batteries from equipment you won't use for a long time to prevent leakage damage.
- Recycle used batteries responsibly rather than putting them in household waste.
Game-Day Readiness
It's worth checking your optic's battery before every game. A dim or flickering dot is a sign the cell is running low, and replacing it before you leave home saves a frustrating moment on the field. If you use several devices, a small battery organiser keeps everything together.
