MELASTA AA/AAA Lithium Batteries, 1.5V 4PC AA 2900mAh & 4PC AAA 1100mAh Long-lasing Replacement for AA/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. headlamps, toys) and low-drain devices Longest life (by far) in single-use category; in a digital camera,AA lithium batteries hypothetically may produce 100–200+ for AA flash photos; alkaline batteries, 20–40+for AA . while AAA 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. Superior functionality in extreme temperatures, from well -40°F to 140°F,
