Energizer Ultimate Lithium AA cells are disposable lithium batteries built for devices that drain alkalines fast: cameras, flashlights, game controllers, smoke detectors and outdoor gear. They weigh about a third less than standard alkaline AAs and are rated to work from -40°F to 140°F. Energizer claims the longest life of any AA, and owners back that up in high-drain and cold-weather use. They cost more than alkalines, so they make most sense where runtime, weight or storage life matters more than the upfront outlay.
