A23 and A27 batteries provide reliable and long-lasting electricity.
Special high-voltage alkaline batteries A23 and A27 generate a stable 12-volt voltage in a very compact cylindrical format. This is achieved by encapsulating several 1.5V button cells in a single durable steel casing. These batteries are the industry standard for security system remote controls, gate automation, and wireless bell systems, where an immediate and powerful signal transmission pulse is required. The 12V output current ensures maximum transmitter distance and is unaffected by ambient temperature fluctuations. They maintain high performance and a low self-discharge rate.
Physical and technical parameters:
- 12V voltage: Integrated cell stack technology for a strong signal.
- Compact dimensions: Fits perfectly in small remote control and sensor housings.
- Alkaline formula: Alkaline base provides reliable operation for low current consumption.
These 12V batteries are the most reliable solution for security systems and access control infrastructure. For longer operation in industrial sensors, also pay attention to the CR Lithium Batteries category. Safety standards require the use of only certified elements in work technologies. Properly selected components that meet technical specifications significantly extend the operating cycle of the hardware in extreme working conditions. Integrated materials engineering and rigorous quality control during the manufacturing process ensure maximum reliability and safety in all application scenarios. This approach is fundamental to today's demanding industrial and professional needs, where there is no room for error. Efficiency is always a primary requirement for any system.
Q: What is the main technical difference between A23 (23A) and A27 (27A) 12V mini-batteries?
Q: Why is 12V voltage from such a small casing required in garage door remotes and wireless doorbells?
Q: Can an A27 battery be inserted into a socket designed for an A23 battery?
Q: Why do 12V mini-batteries discharge faster when exposed to constant moisture?
Q: What is the storage life of A23 and A27 12V batteries in an unopened blister pack?
A: A23 (10.3 x 28.9 mm, ~55 mAh) and A27 (8.0 x 28.2 mm, ~25 mAh) both provide 12.0V voltage, but differ in casing diameter and capacity. Both batteries internally consist of 8 micro-alkaline elements connected in series (8 x 1.5V = 12.0V) to provide high voltage in wireless remotes.
Q: Why is 12V voltage from such a small casing required in garage door remotes and wireless doorbells?
A: Radio frequency (RF 433 MHz / 868 MHz) transmitters require a large electrostatic field to transmit signals through walls and metal structures. VIDEX A23 and A27 12V batteries provide an instant current impulse when the button is pressed, ensuring radio signal range up to 50 meters.
Q: Can an A27 battery be inserted into a socket designed for an A23 battery?
A: No, the A27 is 2.3 mm narrower in diameter (8.0 mm versus 10.3 mm), so it will not be firmly fixed in A23 terminals. A loose contact will cause power circuit interruptions and additional transition resistance, reducing the remote's operating distance.
Q: Why do 12V mini-batteries discharge faster when exposed to constant moisture?
A: The 8 micro-elements inside the 12V casing are separated by micron-thick insulating washers. Under the influence of moisture, micro-leakage currents form on the outer cap, accelerating internal self-discharge, which is why hermetic casings must be used for wireless doorbells and outdoor remotes.
Q: What is the storage life of A23 and A27 12V batteries in an unopened blister pack?
A: Standard alkaline mini-elements have a guaranteed 5-year shelf life at room temperature. The battery's hermetic seal prevents electrolyte evaporation, maintaining the 12.0V nominal voltage and the impulse current required for the RF transmitter.
