Energizer CR2 3V Lithium Battery
The Energizer CR2 3V lithium is a market-leading cell for many handheld laser rangefinders because its compact size, high energy density and stable 3V output during pulsed loads match the demands of optical electronics. Compared with the larger CR123A and AA options in this list it balances capacity and form factor for devices that require a small, reliable power source and is generally more cost-effective than swapping premium AA lithiums for the same runtime.
