Energizer E91 AA Max Alkaline Batteries 1.5V 4-Pack Premium Power

The Energizer E91BP4 AA Max Silver delivers consistent 1.5V alkaline power for tactical equipment, optics, and electronic devices that demand reliable performance. These premium alkaline cells maintain voltage stability under demanding conditions where equipment failure isn't an option.

What Makes This Different

Energizer Max alkaline technology provides up to 50% longer runtime compared to standard alkaline batteries in high-drain devices. The PowerSeal Technology prevents damaging leaks for up to 2 years after fully used, protecting valuable equipment investments. Silver-colored shrink wrap identifies these as premium cells, distinguishing them from basic consumer batteries.

Key Features

• 1.5V nominal voltage with stable power curve throughout discharge cycle
• PowerSeal Technology prevents leakage for 2 years after complete discharge
• 10-year shelf life when stored at room temperature
• Operates reliably in temperatures from -18°C to 55°C (0°F to 131°F)
• Mercury-free alkaline chemistry meets environmental regulations
• Compatible with AA battery compartments in tactical lights, optics, and electronics
• Individual shrink-wrapped cells prevent terminal contact during storage

These cells excel in tactical flashlights, red dot sights, rangefinders, and communication devices where consistent voltage prevents performance degradation. The alkaline chemistry handles both continuous low-drain applications and intermittent high-current pulses without significant voltage drop. Temperature stability ensures reliable operation in field conditions from winter operations to desert environments.
