Whether you call them A23, 23A or 23AE batteries, these little 12V beauties provide the power behind tons of tiny gadgets, including the likes of security fobs, car keys, doorbells and home security systems.

Therefore, it’s essential to have plenty on hand for when your devices run low on juice. Since it’s unlikely you’ll have many things in your home that you can quickly switch out, as well, unlike with AA or AAA batteries, it’s even more crucial to plan ahead and make sure you’re stocked up.

And with the.lint team routinely testing all manner of devices, we thought we’d turn our attention to the little guys keeping everything powered up.

Now, we’d be the first to admit that putting batteries through their paces is a little different to traditional gadgets, which is why we’ve concentrated our efforts on checking out the most popular and well-known 23A options.

From here, we asked two questions: does it work as you would expect, and is it reasonably priced?

Below are the five battery sets that comfortably answered both of those points. continue on to read a bit more, about what you can expect.

Energizer 23A (Five-Pack)

Duracell 23A (Two-Pack)

Amazon Basics 23A (Four-Pack)

LiCB 23A (Five-Pack)

Gold Peak 23A (Five-Pack)

Best 23A battery: Our top pick

Energizer 23A (Five-Pack)

Power your gadgets with a name and battery you can trust.

Being a household name in the world of batteries may not mean that much, but, still, it doesn’t hurt to pick up your A23 batteries from a name you’re likely to be familiar with.

Things are fairly standard here. this pack will deliver 12V of power to your smaller remotes and keyring gadgets, with plenty of shelf life for the batteries you’re keeping in reserve.

In our testing, it was the longest-lasting and offered consistent levels between different cells.

Duracell 23A (Two-Pack)

It might be a little pricier than other options we tested, but you can’t argue with the performance.

Like the rest of Duracell’s speciality battery range, the 23A pair is far from being the cheapest. However, while it lacks that same bit of affordability as others on this list, it does make up for this in its performance.

In use, we found it comparable to Energizer’s option, and it also offers up the same claims of five-year storage. We weren’t able to test this, naturally, but the long-lasting power of each cell bodes well.

Amazon Basics 23A (Four-Pack)

Keep things wallet-friendly with Amazon’s own 23A batteries.

Like the entire Amazon Basics range, things are kept simple with this four-pack of 23A batteries.

In terms of the price per unit, this set is also one of the most affordable on this list, making it a natural pick for those who want to charge their smaller devices without breaking the bank.

Performance was solid, too. Nothing mind-blowing, obviously, these are only batteries, but we will say that you’re not sacrificing much in way of overall performance by deviating away from the traditional battery brands.

LiCB 23A (Five-Pack)

Affordable batteries with a solid shelf life to match.

With this LiCB pack, you’ll be stocked up and ready to power all your smaller gadgets, with each battery offering the potential of more than 100 hours of juice. Like with any battery, though, whether you can eke out anything close to this depends on how you use them.

The 12V alkaline cylinders also have a shelf life of around three years before becoming duds, which means you can keep them stashed away and ready for service at a later date.

Gold Peak 23A (Five-Pack)

An affordable way to stock up on 23A batteries.

Gold Peak’s set of five is another example of how 23A batteries don’t have to burn a hole in your wallet, with this set available at a very affordable rate.

battery

The 12V units are able to power all your smaller compatible gadgets for roughly 100 hours, though, like with others, it’s about how you use them.

We found, for example, that these batteries offered very good performance and lifespan, despite not being best-in-class.

With plenty of shelf life, though, you can keep a few in the drawer and easily replace outgoing units.

How to choose a 23A battery

As we mentioned up top, there’s not actually a whole lot to consider when buying 23A batteries. Design is largely irrelevant and specs are nearly identical across the board, which instead puts the emphasis on price, value and reliability in performance.

Below, we’ll answer a few key questions that should help you choose the right batteries for your needs.

Do you need a 23A battery?

While much rarer than AA and AAA counterparts, 23A batteries are still fairly commonplace in certain appliances and gadgets. However, it can be difficult to know what you actually need, since they go by many different names.

If your device is compatible with one of the following battery codes, this is a sign you need one of the 12V alkaline power sources: 23AE, GP23A, V23GA, LRV08, 8LR932, 8LR23, MN21, L1028 or ANSI-1181A.

How can you spot a 23A battery?

Like us, if you have a drawer full of different, loose batteries, you might already have a 23A battery in your arsenal. Aside from the codes. which are always found on the cell itself. it can be handy to know exactly what one looks like.

A 23 battery is cylindrical, measures 28.5mm long, 10.3mm in diameter, weighs roughly 8-10 grams and will come with a voltage of 12V.

How much should you spend on 23A batteries?

Batteries are certainly an area in which it’s easy to spend. and, in our experience, price and performance don’t necessarily match up. With that said, any set with a single cell costing £0.80. £1 / 1. 1.25 is reasonable. From there, it’s simply about deciding how many you need in your set.

A23, 8LR932, 1811A, V23GA, MN21, 8LR23, A23S Battery Equivalents and Replacements

The A23 battery is a non-rechargeable alkaline cylindrical cell battery often used in small electronic devices requiring higher voltage, like home security systems, garage door openers, Bluetooth headsets, key-less vehicle entry systems, video games controllers, cameras, and other similar devices and electronic gadgets.

The A23 battery is manufactured by most battery brands and finding a replacement battery shouldn’t be a problem. But, like many similar batteries, the A23 battery comes with a broad set of labels, often used by just one manufacturer.

A23 Battery Features and Specifications

The A23 battery’s physical dimensions are 10.3 mm in diameter and 28.5 in length, and it weighs around 0.3 oz (8 grams).

According to the IEC standard, the battery’s label is 8LR932, and according to the ANSI standard, its label is 1811A.

However, the A23 battery is also commonly known as V23GA, MN21, 8LR23, A23S, 23A, 23AE, L1028, 1811A, etc.

Internally, the A23 battery consists of 8 alkaline LR932 batteries connected in series. hence the label according to the IEC standard of 8LR932.

LR932 battery itself is an alkaline battery, 9.3 mm in diameter and 3.2 mm in height, with a nominal voltage of 1.5 volts and a cut-off voltage of 0.9-1.0 volts.

Note: LR932 battery is almost never used as a single battery.

Thus, the A23 battery‘s nominal voltage is 12.0 volts, the cutoff voltage is 6.0-8.0 volts, and the nominal capacity is in the 50-60 mAh range. cutoff voltage also depends on the cutoff voltage of the device, while the capacity also depends on discharge current, battery age, temperature, and similar.

Since LR932 are alkaline batteries (1.5V nominal voltage, 0.9-1.0V cutoff voltage), A23 battery voltage also drops over time, and when the voltage drops down to 6.0-8.0 volts, the battery is considered to be fully discharged.

Note: Temperature also influences voltage, especially when the battery is in use for a longer period of time. If you are facing issues with an ‘almost dead’ battery due to freezing temperature and need your battery for ‘just one more click,’ try to warm it in your armpits for a few minutes. voltage might increase above the required threshold for the device You are having, giving You a chance to use it one more time. Obviously, change the battery as soon as possible!

Energizer A23 Battery

Energizer A23 battery is a non-rechargeable alkaline battery featuring a nominal capacity is 50 mAh, measured using a 20 kΩ resistor at 21°C down to 6.0 volts.

Higher discharge currents lead to capacity drop, for example, at 5 mAh, capacity drops down to ~43 mAh, at 10 mAh, down to ~30 mAh, at 15 mAh, down to ~26 mAh, etc.

Also, actual capacity and the battery runtime depend on the cutoff voltage of the used device. for example, when the battery is discharged using a 20 kΩ resistor/load at 21°C, the typical discharge duration is:

  • down to 8.8 volts: 92 hours,
  • down to 7.2 volts: 98 hours,
  • down to 6.0 volts: 100 hours.

So, the Energizer A23 battery, although alkaline battery, features an output voltage above 9.0 volts for almost 90% of discharge time when discharged using a 20 kΩ resistor/load at 21°C.

That is why it is one of the most popular A23 batteries on the market, used for powering various devices.

Duracell A23 Battery

Duracell A23 battery is a non-rechargeable alkaline battery featuring a nominal capacity of 60 mAh, measured using a 20 kΩ resistor/load at room temperature (~20°C) down to 6.0 volts.

The battery features an annual self-discharge rate of 10% (@20°C), recommended storage temperature range of 5°C to 30°C, and an operating temperature range of.10°C to 60°C.

Duracell A23 battery supports both high- and low-load applications, including pulse applications as well.

For example, when the battery is discharged at room temperature, it can operate:

  • 46kΩ load, initial current 0.22 mA, down to 6 volts: up to 315-320 hours,
  • 20kΩ load, initial current 0.52 mA, down to 6 volts: up to ~130 hours,
  • 10kΩ load, initial current 0.96 mA, down to 6 volts: up to 60-62 hours,
  • 470Ω, down to 8.25 volts: ~40-42 minutes,
  • 15mA, 5s/55s On/Off, down to 6.0 volts: ~2150 pulses.

That is why the Duracell A23 battery is also one of the most popular A23 batteries on the market used for various electronic gadgets, Bluetooth devices, game controllers, door openers, medical devices, calculators, etc.

Of course, there are other reputable and popular battery brands on the market that also make dependable and reliable A23 batteries, for example (Amazon links, open in the new Windows):

A23 Battery vs A27 Battery

A23 batteries and A27 batteries are two very similar batteries, sharing similar dimensions and internal design.

While the A27 battery features dimensions of 8.0 x 28.2 mm and internally consists of 8 (eight) LR632/LR732 batteries, the A23 battery features dimensions of 10.3 x 28.5 mm and internally consists of 8 (eight) LR932 batteries.

A23 Battery A27 Battery

So, A23 and A27 batteries have very similar heights (28.5 mm vs. 28.2 mm), but the A23 batteries are wider (10.3 mm vs. 8.0 mm).

Both batteries feature a nominal voltage of 12 volts, but due to the larger internal volume, A23 features a larger capacity (on average, 50-60 mAh vs. 20-22 mAh).

In most situations, the A27 battery may easily fit into the battery compartment intended for the A23 battery, but with the placement issues. due to the smaller diameter, the A27 battery may have issues with contacts, especially when the device is in motion.

Some devices that are designed to be powered with A23 batteries also feature small plastic battery adapters, being able to hold the A27 battery firmly in place of the A23 battery. this allows the user greater flexibility in finding the required battery replacement, but if the device is regularly used, A27 battery will be discharged much faster than the A23 battery.

A23 Battery vs. N-Cell (E90) Battery

A23 and N-cell (E90) battery feature very similar physical dimensions:

  • A23 battery: 10.3 x 28.5 mm
  • N-cell (E90) battery: 12 x 30.2 mm.

Battery compartments intended for N-cell (E90) batteries may easily accept A23 batteries (again, with possible contact issues), while some (but not all) battery compartments intended for A23 batteries may accept N-cell (E90) batteries.

Also, both A23 and N-cell (E90) batteries are alkaline batteries. and that is where the similarities end!

A23 batteries feature a nominal voltage of 12V, while N-cells feature a nominal voltage of 1.5 volts. if the A23 battery is placed into the battery compartment intended for the N-cell battery, there is a great chance of damaging the device due to the huge voltage difference.

For short, A23 and N-cell batteries are not compatible and should not be used interchangeably!

A23 Battery vs. AAA Battery

Both A23 and AAA batteries are cylindrical batteries featuring similar diameters:

However, two AAA batteries placed one on another feature physical dimensions of 10.5 x 89 mm, while three A23 batteries placed one on top of the others feature physical dimensions of 10.3 x 85.5 mm.

Battery compartments intended for two AAA batteries (total of 3.0 volts) may accept three A23 batteries (total of 36 volts), but such voltage difference may damage even the toughest device.

For short, two AAA batteries cannot and should NOT be replaced by three A23 batteries.

A23 Battery vs. 2/3AAA Battery

A23 and 2/3AAA batteries feature very similar physical dimensions:

While the A23 battery is a non-rechargeable alkaline 12V battery, 2/3AAA batteries are mostly rechargeable Nickel Metal Hydride (NiMH) batteries with a nominal voltage of 1.2V and are commonly used in solar lights, solar lawn lamps, compact LED flashlights, digital cameras, remote control devices, toys, etc.

Obviously, due to the voltage difference, A23 and 2/3AAA batteries are not compatible.

Note: there are several more standard battery sizes that are very similar in size to the A23 batteries, but due to the voltage differences, they should not be used to replace A23 batteries and vice versa.

A23 Battery Safety Issues

Just like any other small and shiny object, the A23 battery may get swallowed by a child or pet. some people consider 10.3×28.5 mm batteries hard to swallow, and they are hard to swallow, but.

Modern A23 batteries don’t contain heavy metals like mercury, lead, and cadmium, but they are nonetheless dangerous, especially 12V batteries, which may cause heavy internal injuries and burns due to electrolysis when they come in contact with the body’s fluids.

If the A23 or any similar battery gets swallowed, call the local emergency center immediately and act according to their instructions.

That is the reason why most brands package their A23/MN21 and similar batteries using so-called ‘pets and kids safe packages’, which are sometimes hard to open even by adults. but better safe than sorry.
