Lithium packs all that power into batteries that are 33% lighter than ordinary AA and AAA alkaline batteries. Overpower the elements with the best batteries in extreme temperatures (from -40° to 140°F). It's not just a photo battery. Make any high-tech battery-powered device run longer with Lithium. Lithium batteries are also built to last longer with world-class, leak-resistant construction.
