Specialty AAAA alkaline cells

These Duracell MX2500B2PK batteries supply 1.5 V alkaline power in a two-cell pack. They are made for devices that require the AAAA form factor such as digital cameras, key fobs, GPS trackers and remote controls.

Replaces single AAAA cells

The pack replaces individual AAAA alkaline cells bought separately, which is useful when a device takes two cells or when a spare is kept on hand. The jump is worth it whenever a device needs a fresh pair at the same time.

Simple drop-in installation

Installation consists of inserting the cells with the correct polarity marked on the device. The only common issue is reversed orientation, which prevents the device from powering on until the cells are turned around.

Questions about this item

Does the AAAA size fit the same slot as a AAA battery?

No, AAAA cells are slimmer and shorter than AAA cells, so they only fit compartments designed for the AAAA form factor.

How do I insert the two cells correctly?

Match the flat negative end to the spring contact and the raised positive end to the flat contact; reversing either cell will prevent the device from powering on.

When should I replace the pair?

Replace both cells together when the device shows low-power warnings or stops working, because alkaline chemistry cannot be recharged.
