Energizer 2032 Lithium Coin Batteries (Energizer part no. 2032BP2) are the compact power source behind many red dot sights, rangefinders, and small electronic devices that take the CR2032 cell. Energizer builds these coin cells with lithium chemistry for a long, stable shelf life, which matters when a red dot might sit mounted and powered for months at a stretch. This 2-pack keeps a spare cell ready so a dimming optic never catches you off guard before a hunt or match.
