The Energizer E91 AA Max alkaline batteries deliver reliable power for tactical equipment, electronic devices, and emergency preparedness gear. These 1.5V cells provide consistent voltage output across extended discharge cycles, making them essential for mission-critical applications where battery failure isn't an option.
What Makes This Different
Energizer Max alkaline technology offers up to 50% longer runtime compared to standard zinc-carbon batteries in high-drain devices. The PowerSeal Technology prevents damaging leaks for up to 10 years in storage, protecting valuable electronics from corrosive damage. These batteries maintain stable voltage output down to -40°F, ensuring reliable operation in extreme environmental conditions.
Key Features
- PowerSeal Technology prevents leaks for 10 years in storage
- Operates reliably in temperatures from -40°F to 140°F
- 1.5V nominal voltage with consistent discharge curve
- 24 individually wrapped batteries for organized storage
- Compatible with tactical lights, optics, radios, and GPS units
