27A 12 Volt Super Alkaline Battery, 5 Count / Blister card package

The 27A is a 12V alkaline battery, also cross-referenced as A27, MN27, and L828, sold here as a 5-count blister card. Like the 23A, it is built from a stacked cell configuration to deliver 12V output for devices that require higher voltage than a standard 3V coin cell, including keyless entry transmitters, garage door openers, and alarm system remotes. Non-rechargeable. Confirm the required voltage against the specific transmitter before ordering.
