Energizer A23 Batteries 2 Pack: Reliable 12V Power for Compatible Devices
The Energizer A23 Batteries 2 Pack is a practical option for powering compatible electronic devices that require a small 12-volt alkaline battery. Designed for specialty electronics, these compact batteries are commonly used in compatible remote controls, keyless-entry systems, garage door remotes, and other low-power electronic applications.
If your device has stopped responding or its remote control needs a replacement battery, choosing the correct battery size and voltage is essential. The Energizer A23 provides a compact 12V power source designed for devices that specifically require the A23 battery type.
In this guide, you will discover the main features of Energizer A23 batteries, compatible applications, technical specifications, advantages, limitations, and what to check before purchasing.
Quick Answer: Are Energizer A23 Batteries Worth Considering?
Energizer A23 batteries are worth considering if your electronic device specifically requires a 12V A23 alkaline battery. This two-pack provides two batteries for compatible devices, making it useful when you need a replacement now and want another battery available for later.
The most important consideration is compatibility. A23 batteries are not interchangeable with ordinary AA or AAA batteries simply because they are all used in electronic devices.
Check your device’s manual or existing battery label before purchasing.
What Are Energizer A23 Batteries?
Energizer A23 batteries are miniature alkaline batteries designed for specialized electronic applications. Each battery has a nominal voltage of 12 volts and uses alkaline battery chemistry.
Unlike standard AA and AAA batteries, A23 batteries are smaller specialty batteries intended for devices that require their particular voltage and physical dimensions.
Common compatible applications include:
- Garage door remote controls
- Keyless-entry systems
- Certain wireless remote controls
- Compatible security and electronic access devices
- Other electronics specifically designed for A23 batteries
Not every device in these categories uses an A23 battery. Always confirm the required battery type before replacing an existing battery.
Key Features of Energizer A23 Batteries
1. 12-Volt Alkaline Power
Each Energizer A23 battery provides a nominal voltage of 12 volts.
Why it matters: The correct voltage helps a compatible device operate as intended. If your remote or electronic device specifies A23 12V, this battery type may be an appropriate replacement.
Never substitute a battery with a different voltage unless the device manufacturer confirms that it is compatible.
2. Compact Specialty Design
A23 batteries have a small cylindrical shape designed for electronic devices with limited battery space.
Why it matters: Their compact dimensions make them suitable for certain remote controls and keyless-entry devices where a standard AA or AAA battery will not fit.
3. Convenient Two-Pack
The package contains two batteries.
Why it matters: You can replace a depleted battery and keep the second one available for a future replacement, provided it is stored appropriately.
4. Alkaline Battery Chemistry
Energizer A23 batteries use alkaline chemistry, based on manganese dioxide and zinc.
Why it matters: Alkaline batteries are designed for convenient, ready-to-use power without requiring a separate charging process.
These batteries are primary cells, so they should not be recharged.
5. Designed for Specialty Electronics
The Energizer A23 is designed for electronic applications that may require brief, relatively high-current pulses.
Why it matters: Certain remote-control and electronic access systems draw power in short bursts when a button is pressed. The A23 battery is designed for this type of application when the device specifies it.
6. Alternative Battery Designations
Depending on the device manufacturer’s specifications, compatible replacement designations may include 23A, 23AE, 1181A, A23BP, DL21, DL23, MN21, MN-21B, and V23GA.
These designations are commonly associated with A23-type batteries, but you should verify the exact replacement requirements for your device.

What Devices Use Energizer A23 Batteries?
Garage Door Remote Controls
Some garage door remote controls use A23 batteries to power their electronic transmission functions.
If your garage remote has stopped working, check its battery compartment or owner’s manual to determine whether it requires an A23 battery.
Replacing the battery may help restore operation when a depleted battery is the cause of the problem.
Keyless-Entry Systems
Certain keyless-entry devices use A23 batteries to provide power for electronic access functions.
Always confirm the required battery designation because different keyless-entry systems can use different battery sizes and voltages.
Wireless Remote Controls
Some wireless remote controls require compact 12V batteries rather than standard household batteries.
The Energizer A23 may be suitable when the device specifically lists A23, 23A, MN21, or another confirmed compatible designation.
Other Specialty Electronics
Certain security accessories and small electronic devices also use A23 batteries.
Check the manufacturer’s specifications instead of assuming that every security device or remote uses the same battery.

How to Choose the Correct A23 Battery
Before buying a replacement battery, follow these simple checks:
- Check the existing battery. Look for the A23 or 23A designation.
- Verify the voltage. Confirm that the device requires 12V.
- Read the device manual. Check the manufacturer’s approved battery types.
- Confirm polarity. Install the battery according to the positive and negative markings.
- Check the packaging. Ensure the product is the correct Energizer A23 model and pack quantity.
These checks can help prevent compatibility problems and incorrect installation.
Battery Storage and Disposal
Store unused batteries in a cool, dry location and follow the storage instructions printed on the package.
Keep batteries away from excessive heat and moisture. Avoid storing loose batteries with metal objects that could cause a short circuit.
Never attempt to recharge an alkaline A23 battery, puncture it, or expose it to fire. Keep batteries out of reach of young children.
Dispose of used batteries according to local collection and recycling requirements. Do not assume that every community accepts batteries through ordinary household waste collection.
