Energizer L91 AA Ultimate Lithium Batteries 1.5V (8-Pack)

The Energizer L91 AA Ultimate Lithium batteries deliver exceptional power density and temperature performance for high-drain tactical equipment. These lithium cells outperform alkaline batteries in extreme conditions while maintaining consistent 1.5V output throughout their discharge cycle.

What Makes This Different

Lithium chemistry provides 33% more power than standard alkaline batteries and operates reliably in temperatures from -40°F to 140°F. The L91 cells weigh 33% less than alkaline equivalents, reducing carried weight for extended operations. These batteries maintain 90% of their original capacity after 20 years of storage, eliminating concerns about shelf life degradation.

Key Features

• Lithium iron disulfide chemistry for superior energy density
• Operates effectively in extreme temperatures (-40°F to 140°F)
• 20-year shelf life with minimal capacity loss
• 33% lighter weight than comparable alkaline batteries
• Leak-resistant construction prevents equipment damage
• 1.5V nominal voltage throughout discharge curve
• Compatible with all AA battery devices and equipment

These batteries excel in high-drain applications including tactical flashlights, GPS units, night vision equipment, and electronic optics. The consistent voltage output prevents dimming in LED flashlights and maintains accuracy in electronic rangefinders. Cold weather performance makes them suitable for winter operations where alkaline batteries fail.
