Description

The Energizer A27 is a 12V alkaline battery measuring 8mm in diameter and 28mm in length, supplied in a 2-pack blister card. The A27 designation (also sold as E27A, MN27, L828) refers to a specific miniature battery format built from eight individual LR732 button cells stacked in series to deliver 12V output from a single cylindrical unit.

Designed for low-drain devices that require 12V power in a compact format, the A27 is commonly fitted in car alarm key fobs, garage door remote controls, wireless doorbells, and some medical alert pendants. The alkaline composition provides a shelf life of several years when stored at room temperature, making the battery suitable for devices that sit idle for long periods between use. The 2-pack format gives a spare battery for immediate replacement when the first cell depletes.

The Energizer A27 fits devices specifying A27, E27A, MN27, L828, V27A, GP27A or similar cross-reference codes. The 8mm diameter and 28mm length are standardised across manufacturers, so the Energizer A27 is a direct replacement for any device requiring this cell size. The blister pack protects the batteries from short-circuit during storage and can be opened without tools.

Frequently Asked

What devices use A27 batteries?

A27 batteries are most commonly found in car alarm key fobs, garage door remote controls, wireless doorbells, and some medical alert pendants. Any device marked A27, E27A, MN27, L828, V27A or GP27A on the battery compartment uses this cell size.

How long do A27 batteries last?

Shelf life is typically 3-5 years when stored at room temperature. In-device lifespan depends on usage frequency — a car key fob used several times daily may last 6-12 months, while a garage door remote used less frequently can last 1-2 years on a single cell.

Are A27 and MN27 the same battery?

Yes. A27, E27A, MN27, L828, V27A and GP27A are different manufacturer codes for the same 12V alkaline battery in the same 8mm x 28mm format. The Energizer A27 is a direct replacement for any of these codes.

Can A27 batteries be recharged?

No. The A27 is an alkaline primary cell and cannot be recharged. Attempting to recharge alkaline batteries can cause leakage or rupture.
