CR1620 3V Lithium Coin Cell Battery

The CR1620 is a thin 3V lithium coin cell used in a number of compact red dots, laser sights, torches and PEQ-style units. It's smaller than the more common CR2032, so check your device before ordering. The size is usually printed on the old battery or inside the battery cap.

Lithium cells keep their charge well when stored, so one sitting in your chest rig or kit bag will be ready when you need it.
