A23 Batteries

A23 batteries are small cylindrical cells commonly used in devices that need a compact 12V power source, like remote controls, keyless entry systems, and garage openers.

These batteries typically use alkaline chemistry with manganese dioxide as the cathode. They provide a nominal voltage of 12V and a capacity of around 50–60mAh, making them suitable for low‑to‑moderate current draw in compact electronics.

A23 cells are lightweight and compact, yet deliver high voltage in a small form factor. They’re an ideal choice when you need reliable, portable power and don’t require high capacity.
