GP Lithium 9V Battery CR-V9 / L522 / LA522 / 6F22
GP Lithium 9V batteries offer excellent longevity and are ideal for essential home devices such as smoke detectors, where they last 65% longer than standard alkaline batteries. A mains-powered smoke detector with up to a 10-year lifespan remains active for the full decade when used with a backup battery. This is twice as long as with an alkaline battery.
Professional audiovisual equipment users, such as wireless microphone operators, can perform up to 5 times longer with Energizer Lithium 9V batteries than with standard 9V alkaline batteries.
