Description
The 12V 23A Battery (also known as A23, MN21, V23GA, or 23AE) is a small high-voltage alkaline dry cell battery commonly used in compact electronic devices that require short bursts of power. It provides a 12-volt output but has a very low capacity, making it suitable only for low-current applications.
It is widely used in remote controls, car key fobs, wireless doorbells, alarm systems, and garage door openers.
