A23 - A27
Suddenly can't open the garage doors, turn off the car alarm, or ring the wireless doorbell? Your remote battery might be dead. VIDEX A23 and A27 (12V) alkaline batteries are designed specifically for high-power remote controls.
Why VIDEX 12V batteries are the best choice:
- Strong and instant signal: Provides stable 12V power for a greater remote operating range (gates and barriers).
- Long shelf life: Up to 5 years - buy a pack and keep it in the glovebox for emergencies.
- Stability in temperature fluctuations: They won't let you down even on cooler mornings.
Make sure your gates and car always open. Buy remote control batteries at opentools.lv!
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.
