Energizer A27 Alkaline Batteries - 2 Pack

The A27 is a 12V alkaline cell, supplied here two to a pack. It sits in Energizer's Specialty range, which covers the formats most people only meet once, when something small stops working and an unfamiliar code comes out of the battery compartment. Alkaline is the standard single-use chemistry: it keeps its charge well while sitting on a shelf and gives a steady output until it is spent. The 12V rating is printed on the pack, and it is what separates this cell from the 1.5V sizes that fill most kitchen drawers.

A cell of this size and voltage is usually asked for by something handheld: key fobs, gate and garage handsets, small alarm remotes and the odd camera accessory are where 12V specialist cells of this type normally live. Whatever the device, the way to be sure is the same. Take the old cell out and read the code printed along its body; if it reads A27, this is the replacement. Nothing about the fitting is adjustable, so a cell that is close but not exact will either refuse to seat or make poor contact once the cover is back on.

Each pack holds two cells. The minimum order on this listing is ten packs, sold in multiples of ten, so the smallest quantity that leaves us is twenty cells: sensible for a maintenance cupboard or a workshop drawer, less so for one dead key fob. Energizer's alkaline cells are also on our shelves in the AA, AAA, C, D and 9V sizes if you are stocking up more widely. The manufacturer does not state a shelf life for this pack. There is nothing to set up or configure; the cells arrive ready to fit.

What voltage does an A27 cell give?

Twelve volts, printed on the pack as 12V. That is well above the 1.5V of an AA or AAA, so a standard household cell is not a substitute.

How many cells come in a pack, and what is the smallest order?

Each pack holds two A27 cells. Orders start at ten packs and run in multiples of ten, which works out at twenty cells.

Can these cells be recharged?

No. Alkaline is a single-use chemistry and these cells are not made to go on a charger, so fit fresh ones when the device weakens.

How do I know an A27 is the right cell for my device?

Take the old cell out and read the code printed along its body. If it reads A27, this pack replaces it, and the device manual will confirm the same.

Is a shelf life printed on the pack?

The manufacturer does not state a shelf life for this pack. Alkaline cells do hold their charge well in storage, which is why they suit a spares drawer.
