The Toshiba 23A Battery is a compact, high-voltage alkaline power cell designed for small electronic devices that require a 12 V power source. Ideal for use in remote controls (such as car key fobs and garage door openers), alarm systems, sensors, and other compact electronics, this battery delivers stable power with long shelf life and resistance to leakage. Its small cylindrical form factor makes it suitable where space is limited, and the alkaline chemistry provides reliable performance over extended periods. The battery is a **primary (non-rechargeable)** cell meant for one-time use, and is free from mercury for safer handling and disposal.
