Energizer Lithium Batteries CR2016 2pk

The Energizer CR2016 coin-sized battery is one of the most commonly chosen and used 3V lithium cells for devices ranging from key fobs, calculators, medical devices, remote controls, toys 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.
