These rechargeable Lithium cells are designed to have a ten-year life and outlast the life of the smoke alarm itself. They provide up to six months of smoke alarm operation without mains power. The Ei161RC is supplied with the Easi-fit base that allows very quick and simple installation of the smoke alarm, combined with simple detector head removal and replacement. The Easi-fit base automatically connects both mains power and battery as the detector head slides on.
