Energizer Ultimate Lithium AAA Batteries – Pack of 8
Energizer Ultimate Lithium AAA Batteries – Pack of 8. Designed for power users and professionals with multiple high-drain devices, each cell uses LiFeS2 chemistry to deliver a nominal 1.5 volts and up to 1,200 mAh of capacity. A flat discharge curve keeps devices running at full strength far longer than alkaline alternatives, and each cell is approximately 33% lighter than a comparable alkaline AAA.
Leakproof construction protects valuable equipment from corrosive failure, and a 20-year shelf life makes this eight-pack a practical buy for studios, field crews, and emergency preparedness kits. Rated for -40°F to 140°F, these cells perform in any condition.
