Battery Energizer A23 — 12V alkaline miniature battery, 1 piece

Energizer A23 — 12V alkaline miniature battery, 1 piece is a compact high-voltage cell designed to supply stable power to small electronic devices. The single-piece package fits devices that require an A23 (also labelled 23A) 12V battery and delivers the alkaline chemistry performance expected from the Energizer brand. Its cylindrical form factor and compact dimensions make it suitable where a small battery with a relatively high nominal voltage is required.

Advantages

This Energizer A23 battery offers reliable voltage output and consistent discharge behavior appropriate for intermittent and low-to-moderate current applications. The alkaline chemistry provides good shelf life and resistance to leakage when used according to manufacturer guidance. Its compact size and standardized polarity make replacement straightforward in compatible remotes, key fobs, and sensors.

Suitable for

• Remote controls for garage doors, car alarms and multimedia devices
• Key fobs and vehicle security transmitters
• Wireless security sensors and door/window sensors
• Small wireless gadgets such as some cameras, LED flashers, and electronic toys

Key specifications

• Chemistry: Alkaline
• Nominal voltage: 12 V
• Cell format: Miniature cylindrical battery (A23 / 23A form factor)
• Quantity: 1 piece
• Typical applications: Low-to-moderate current drain devices requiring high nominal voltage

How to use

Insert the battery into the device observing the correct polarity as indicated in the battery compartment. Ensure contacts are clean and free of corrosion before installation. After fitting, verify device operation; if the device does not power on, check battery seating and polarity again. Replace with the same battery type to maintain proper voltage and performance.

Usage recommendations

Store the battery in a cool, dry place away from direct heat and sunlight. Remove spent batteries from devices promptly to reduce the risk of leakage. Do not attempt to recharge, disassemble or expose the battery to fire. Dispose of used batteries in accordance with local regulations for battery recycling or hazardous waste collection.
