Description
These A27 (27A/MN27) 12 V alkaline cells are a perfect fit for small devices that need a quick burst of voltage—think car key fobs, garage/gate remotes, wireless doorbells, RF triggers and security sensors. The Voniko-branded pack delivers stable performance, long shelf life, and broad cross-compatibility with common A27 part numbers, so replacements are easy to find when you need them.
