melasta AAA Lithium Batteries, 16-Pack 1.5V 1100mAh Long-lasing Triple A Battery Replacement for AAA Alkaline Batteries (Non-Rechargeable)

Lithium, an exceptionally light metal, gives lithium batteries the highest energy density of any battery cell. Thus, they can store more energy than alkaline batteries or any single-use battery of a comparable size. And they are superb performers in extreme temperatures, both hot and cold. USE WITH CAUTION: Their higher voltage capacity makes lithium batteries too powerful for some devices and may damage circuitry. Read manufacturer instructions for battery recommendations for individual products. Best use: High-drain devices (eg. digital cameras), most (but not all) moderate-drain devices (eg. headlampsv toys) and low-drain devices. Longest life (by far) in single-use category; in a digital camera, lithium batteries hypothetically may produce 30-60+ flash photos; alkaline batteries, 10-20+. Long shelf life: Holds power up to 10 years in storage for trustworthy backup energy, so you can get ready for any emergencies or use immediately. Light weight: approximately 30% lighter than equivalent sized alkaline batteries.
