The Energizer CR2032 coin cell battery is one of the most commonly used 3V lithium cells in devices ranging from key fobs to computer memory backup. This convenient 2-cell pack from Energizer gives you a reliable power source now and a spare for later.

Due to their lithium chemistry, you can set one of these batteries aside as a spare for up to 8 years. The lithium make-up also means these cells are very light in weight and extremely temperature tolerant, performing reliably at -20C to 60C.
