What Is the Voltage of an A23 Battery and Why Does It Matter?
The A23 battery delivers a nominal voltage of 12 volts, significantly higher than common AA or AAA batteries. This high voltage is essential for powering small electronic devices like key fobs and garage door openers that require compact yet strong energy sources. Its voltage ensures reliable performance in radio frequency transmission and other specialized applications.
What Is the Nominal Voltage of an A23 Battery?
The nominal voltage of an A23 battery is 12 volts. This voltage is achieved by stacking eight smaller LR932 alkaline cells in series inside the battery casing. The 12V output is much higher than the typical 1.5V from AA or AAA batteries, making the A23 suitable for devices needing higher voltage in a compact form.
Why Does the Voltage of an A23 Battery Matter?
The 12V voltage is crucial because many small electronic devices, such as keyless entry systems, garage door openers, and remote controls, require higher voltage to operate effectively. The higher voltage enables efficient radio frequency transmission and reliable device activation, which lower-voltage batteries cannot provide.
How Is the A23 Battery Constructed to Achieve 12 Volts?
The A23 battery contains eight individual LR932 alkaline button cells connected in series. Each cell contributes about 1.5 volts, and their combined voltage sums to approximately 12 volts. This multi-cell design allows the battery to maintain a compact size while delivering the required voltage.
What Are the Typical Dimensions and Weight of an A23 Battery?
An A23 battery measures approximately 28.2 to 28.9 mm in length and 10 mm in diameter, weighing around 8 grams. Its compact cylindrical shape is roughly two-thirds the length of an AAA battery, making it ideal for devices where space is limited but high voltage is necessary.
Which Devices Commonly Use A23 Batteries?
A23 batteries are commonly used in car remote controls, garage door openers, home security systems, Bluetooth trackers, and small medical devices. These applications benefit from the battery’s compact size and high voltage, which supports reliable wireless communication and device operation.
How Does the A23 Battery Compare to Other Similar Batteries?
Compared to AA or AAA batteries, which provide 1.5 volts, the A23’s 12 volts is significantly higher. It is similar in voltage to the A27 battery but slightly larger in diameter. The A23 offers a capacity of about 55 mAh, sufficient for low-drain devices requiring intermittent bursts of power.
| Specification | A23 Battery | AA Battery | A27 Battery |
|---|---|---|---|
| Nominal Voltage | 12 V | 1.5 V | 12 V |
| Capacity | ~55 mAh | ~2000-3000 mAh | ~20-30 mAh |
| Diameter | 10 mm | 14.5 mm | 8 mm |
| Length | 28.2 – 28.9 mm | 50.5 mm | 28 mm |
| Weight | ~8 grams | ~23 grams | ~4 grams |
What Chemical Composition Does the A23 Battery Use?
The A23 battery uses alkaline chemistry, primarily manganese dioxide (MnO2) as the cathode and zinc as the anode. This combination provides stable voltage output, good shelf life, and reliable performance in low-drain applications. The alkaline system also offers excellent resistance to corrosion.
How Long Does an A23 Battery Typically Last?
An A23 battery typically has a capacity around 55 mAh and a shelf life of 3 to 5 years under proper storage conditions. Its lifespan in devices depends on usage patterns but generally supports low-drain electronics requiring intermittent power bursts rather than continuous high current.
Can the Voltage of an A23 Battery Vary When Fresh or Used?
Yes, a fresh A23 battery can measure slightly above 12 volts (around 12.4V), while a used or partially depleted battery voltage may drop to around 11.8 volts or lower. Devices designed for A23 batteries tolerate this voltage range to ensure consistent operation until near depletion.
