Energizer AA Alkaline Battery E91 1.5V, 2850mAh, 10-Year Shelf Life

Disposable Alkaline Cell for Everyday Devices

The Energizer AA battery is a 1.5V primary cell built on a zinc-manganese dioxide chemistry. It ships as a single AA (LR6, ANSI 15A) unit for remotes, torches, clocks and wireless peripherals. The cell holds a nominal capacity of 2850 mAh at a low discharge rate.

Nominal voltage sits at 1.5V with a discharge cut-off of 0.8V. Diameter measures 14.5 mm and overall height 50.5 mm, which matches the IEC LR6 envelope. Typical weight lands at 23 g per cell. Internal resistance falls between 150 and 300 milliohms on a fresh unit.

Storage life reaches 10 years at 21°C, holding about 80% of initial capacity. The cell operates from -18°C to 55°C. It carries no mercury or cadmium, so disposal follows standard alkaline routes. A plastic label jacket insulates the can against incidental contact in a battery compartment.

The pressure-contact terminal uses a raised positive nub and a flat negative base. That geometry seats in spring-loaded holders, screw terminals and blade contacts. Installers can stock one SKU across keyboards, mice, TV remotes, wall clocks and test meters. The cell suits low and moderate drain profiles rather than high-current motor loads.

Key Features

• 1.5V Alkaline Chemistry
  Zinc-manganese dioxide construction delivers a stable 1.5V nominal output through most of the discharge curve.

• 2850 mAh Nominal Capacity
  The rated capacity supports long standby intervals in clocks, remotes and sensors.

• Ten-Year Storage Window

  • Retains roughly 80% capacity after 10 years at 21°C
  • Suitable for bulk stocking across procurement cycles
  • Date coding on the jacket supports stock rotation

• Wide Thermal Envelope
  The cell runs from -18°C to 55°C, covering cold stores and hot vehicle cabins.

• Mercury and Cadmium Free
  The formulation meets modern disposal rules for household alkaline waste.

• Standard LR6 Footprint
  The 14.5 x 50.5 mm can drops into any AA holder without modification.

What’s in the Box

• Energizer AA alkaline cell, 1.5V

Why Choose the E91 Cell

• The 10-year shelf figure lets procurement hold buffer stock without frequent reordering.

• Standard LR6 dimensions fit existing holders, so no adapter or compartment change is needed.

• The alkaline chemistry tolerates the intermittent drain profile of remotes and clocks better than high-rate cells.

• Absence of mercury and cadmium simplifies end-of-life handling under local waste rules.

• Raised positive and flat negative terminals seat correctly in spring and blade contacts.
