GP 27A High Voltage Alkaline Battery 12V – 8.0 x 28.2 mm, 4.4g, 3-Year Shelf Life

12-Volt Alkaline Cell for Access Devices

The GP 27A battery is a 12-volt alkaline cell for remote controls, doorbells and garage openers. It measures 8.0 mm in diameter and 28.2 mm in height. Sealed construction limits leakage during extended storage.

Alkaline chemistry holds a nominal 12V output across the discharge curve. The cell weighs 4.4 g and carries a 3-year shelf life when stored dry and away from direct sunlight. GP compresses the active materials at high density to keep voltage stable under load.

Equivalent part numbers cover A27, MN27, V27A, L828 and 8LR732 sockets. Typical loads include car key fobs, wireless doorbells, pet collars and medical devices. The mercury-free formulation meets environmental disposal requirements.
