Energizer L91 AA Ultimate Lithium Batteries 1.5V (4-Pack)

The Energizer L91 AA Ultimate Lithium batteries deliver exceptional power and reliability for tactical equipment, optics, and electronic devices. These lithium cells maintain consistent 1.5V output across extreme temperature ranges where alkaline batteries fail.

What Makes This Different

Lithium chemistry provides up to 8 times longer life than standard alkaline batteries in high-drain devices. The L91 cells operate reliably from -40°F to 140°F, making them ideal for outdoor gear and mission-critical equipment. Weight reduction of 33% compared to alkaline batteries matters when every ounce counts in tactical applications.

Key Features

• 15-year shelf life ensures readiness for emergency situations
• Leak-proof construction protects valuable electronics
• Performs in extreme temperatures from -40°F to 140°F
• 33% lighter weight than comparable alkaline batteries
• Powers high-drain devices like GPS units, flashlights, and optics
• Single-use lithium cells with consistent 1.5V output
• Four individual batteries in retail packaging

Field performance remains consistent whether powering red dot sights during extended range sessions or keeping GPS units operational in harsh weather. The lithium chemistry maintains voltage under load better than alkaline alternatives, preventing device shutdowns during critical moments. These batteries excel in applications requiring reliable power over extended periods.
