Ultralife Next Generation 9-Volt Lithium Battery lasts up to 5 times longer than ordinary alkaline and 10 times longer than carbon-zinc. The replaceable battery has the highest energy density, flattest discharge voltage curve, longest shelf life, widest operating temperature range, and lightest weight of any comparable 9-volt battery. The battery meets ANSI Alkaline 1604 size specifications and has overcurrent protection. The Ultralife Next Generation 9 Volt Lithium Battery's 10-year service life makes this the battery of choice for major smoke alarm manufacturers for their 10-year ion-type smoke alarms. Designed for up to 10-year service life for certain devices, including most ionization type smoke alarms High energy density, up to 5x more than alkaline, up to 10x more than carbon zinc High running voltage Flat discharge voltage curve Low impedance, better performance at low temperatures Advanced safety features - over current protection Lightweight - 18% less than alkaline Wide operating temperature range Meets ANSI Alkaline 1604 size specifications Low short circuit temperature.
