You need a 23a 12v Battery for the small devices that seem to stop the moment you need them most, from garage remotes to key fobs and door chimes. The right pack saves you from opening the same device twice because the first cell was the wrong size, the wrong chemistry, or just too short-lived for regular use. This roundup keeps the focus on fit, pack count, and brand consistency so you can match the battery to the device without second-guessing it.

More Details On Our Top Picks
The GP 20-pack makes sense for homes that keep a small stack of remotes, alarm panels, or door sensors in rotation. The larger count also cuts down on repeat orders, which helps when a tiny battery always seems to vanish at the wrong moment.
You get a straightforward alkaline setup here, so the appeal is less about flash and more about having enough cells on hand. The trade-off is simple, bulk packs suit households that use this size often, not people who replace one battery every few years.
Strong Points
- 20-cell supply covers several devices at once
- Alkaline chemistry suits everyday household use
- Brand-name packaging helps keep replacements consistent
- Useful for homes that like spare cells ready
Things To Consider
- The larger pack makes more sense for regular use than occasional replacement
- Bulk storage needs a dry drawer or bin so the cells stay organized
Key Specs
Who It Suits Best
Households with several A23 devices and a habit of keeping spares close by will get the most from this pack.
A Better Fit Elsewhere
Energizer A23 Batteries 2 Pack is a cleaner fit for you if you only need a couple of cells for one remote or alarm component.
This two-pack keeps things simple for a drawer, garage remote, or backup alarm sensor. Compared with the GP 20-pack, it trims the quantity down hard, which is useful when you only replace this size once in a while.
The listing leans on A23 compatibility, so the real advantage is convenience rather than surplus. The honest read is that small packs are easier to store neatly, though they also disappear faster once a few devices start needing fresh cells.
What We Like
- Small count suits low-volume replacement needs
- Compatible format keeps the shopping process straightforward
- Easy to tuck into a tool drawer or kitchen junk drawer
Room For Improvement
- Two cells can feel thin for homes with several remotes
- Smaller supply means you may restock sooner
Feature Card
The Right Fit
Light-use households and people who prefer a tiny spare stash will feel right at home with this pack.
Swap It Out When
GP A23 12V Alkaline 23-A Replacement Battery 23AE 20 Pack suits busier homes better, especially where several devices use this size at once.
The Energizer pair sits in a familiar middle ground, with a compact two-cell format that suits the usual remote or keyless-entry job. Compared with the generic two-pack, this one leans on a more familiar brand name, which can matter when you want less guesswork on a small but important cell.
Miniature alkaline means a standard everyday chemistry in a very small body, and that matters because these devices often sit unused until they suddenly need power. You may find the two-pack just right for keeping one spare around, though it’s not the pick for households that burn through A23 cells quickly.
Positives
- Two-pack format keeps replacement simple
- Brand familiarity can make repurchasing easier later
- Compact size fits the small devices that use A23 cells
- Good for keeping one battery on hand and one in use
Points To Note
- Small count is less useful for homes with multiple devices
- Storage still matters, since loose coin-style cells can wander in drawers

Whose Shelf It Belongs On
It suits you best if you want a familiar brand in a simple two-pack for low-drama replacement use.
Another Choice May Suit
GP A23 12V Alkaline 23-A Replacement Battery 23AE 20 Pack is the smarter fit for busy households that would rather stock up once than revisit the drawer every few weeks.
This one shifts away from the A23 lane and into 27A territory, so it matters for a different set of remotes and small controls. That makes it a better match for homes where the device manual calls for 27A, not the slightly larger A23 style.
The five-pack is handy for households with a ceiling fan remote, a garage door opener, or a similar compact control that eats through cells over time. The trade-off is obvious, it only helps you if the device actually needs 27A, so careful matching pays off here.
Highlights
- Five-cell pack supports several replacements
- 27A format suits a distinct device group
- Useful for remotes that stay in service year-round
- Good stash size for a utility drawer
Softer Spots
- Not the right fit for A23 devices
- Mixed household compatibility can be confusing without a quick manual check
Core Details
Perfect Match For
People replacing batteries in the right 27A remotes or controls will get the most value from this pack.
Where A Sibling Pick Shines
Energizer A23 Batteries 2 Pack is the cleaner route for you if the device asks for A23 rather than 27A.
GP shows up again here in a smaller two-pack, which makes this option feel tidy rather than overcommitted. Compared with the GP 20-pack, the appeal changes from bulk to convenience, especially for a single device or a small backup stash.
The 23AE format is the important part, because it keeps the battery aligned with compact remotes and other low-volume household gear. You may find this size easier to store than a larger multipack, though the smaller count means a second device can empty the box quickly.
Best Bits
- Small pack suits light replacement habits
- 23AE format fits the right compact devices
- Simple to stash in a desk or utility drawer
- Good match for one-off battery changes
Minor Gripes
- Two cells may feel limited for multi-device homes
- Less practical if several remotes use this size
Feature Rundown
Made For
It suits you best when you need a neat two-cell supply for a single remote or other small household device.
Look Elsewhere When
GP A23 12V Alkaline 23-A Replacement Battery 23AE 20 Pack fits better for busier homes that want a deeper reserve.
Rayovac’s two-count layout is a tidy fit for keyless-entry setups and the sort of remotes that sit idle most of the time. In most homes, that makes it a practical middle option, not too small, not overly stocked.
The listing language points to keyless use, which is useful because those devices tend to be frustrating when the battery fades. The trade-off is that a pair is still a short reserve, so busy households may outgrow it faster than the GP 20-pack.
Upsides
- Two-count pack keeps replacement straightforward
- Good match for keyless-entry devices
- Brand familiarity can make the choice feel steadier
- Easy to tuck into glove boxes or utility drawers
Worth Noting
- Only two cells, so it is better for modest use
- Not the right call for people wanting a larger reserve

Built With In Mind
It suits you best if you want a compact two-battery set for a keyless-entry remote or similar device.
Reach For A Different Pick When
GP A23 12V Alkaline 23-A Replacement Battery 23AE 20 Pack is a better match for households that would rather store extras than restock often.
This Bvgokcell pack is aimed at the less common 27A format, so it’s the one to check for ceiling fan remotes, garage door accessories, doorbells, or key fobs that call for that exact size. Compared with the SKOANBE five-pack, it serves the same battery class, but the product-page wording gives you a clearer sense of the everyday devices it’s meant to cover.
The five-count box is handy for a home that uses a few narrow-format controls across the house. One thing worth considering is that 27A and 23A are easy to confuse at a glance, so matching the device code matters more here than brand preference alone.
Reasons To Buy
- Five-pack gives you a useful reserve
- 27A size fits a specific device group
- Helpful for ceiling fan remotes and similar controls
- Good choice for keeping several spares together
Areas To Watch
- Only works for 27A devices, not A23 models
- Device labeling needs a quick check before ordering
Quick Facts
Who Should Grab It
It suits you best if your home uses several 27A-powered remotes or controls and you want a modest stash.
Consider Something Else When
Rayovac 23A Alkaline Batteries 12V Keyless 2 Count is the better match for you if your device takes 23A rather than 27A.
How To Choose The Right 23a 12v Battery
Match The Exact Cell Code
The first job is matching the battery code on the device, not just the voltage. A23, 23AE, 27A, A27, LR27A, and MN27 sound close, but they do not always fit the same compartment or contact layout.
That matters most in remotes, keyless entry units, and alarm components, where a cell that is even slightly off can leave you with a battery that looks right but does nothing useful. The device label or old battery usually tells you the safest path.
Choose Pack Count Around Usage
A two-pack works well for a single remote or a spare kept in a drawer. A larger bundle makes more sense in a home with several devices, especially where the same battery size pops up in different rooms.
Bulk is not only about quantity, it also changes how often you need to reorder. That simple shift can save you from the small hassle of opening the same gadget again a few months later.
Look At Chemistry And Brand Consistency
Most picks here use alkaline chemistry, which is the common everyday route for small household electronics. The important part is consistency, because a familiar brand or repeated product line can make restocking less uncertain.
You may notice that brand name matters more in categories like this than in larger batteries, since these cells often sit unused until the exact day you need them. That is where a steady product line can feel reassuring, even without any fancy extras.
Think About Storage And Device Fit
Small batteries are easy to misplace, so storage matters more than people expect. A sealed drawer, labeled bin, or original card keeps them from rattling around with screws and tape.
The other practical point is temperature and handling during storage, since loose cells can get bent, nicked, or simply forgotten. Treat the spare pack like a small toolkit item, and it stays useful longer.
What To Weigh Before You Decide
Common Shopping Slip Ups
The biggest mistake is treating every 12V small cell as the same size. A23 and 27A are different, and device labels usually settle the question faster than product photos do.
Another common miss is buying too few cells for a home that uses the same battery in several spots. A tiny pack may look neat, but it can feel cramped once the second or third device needs attention.
The Case For Spending Up
Higher-tier options in this category usually cost more because you are paying for brand consistency, clearer labeling, and more cells in the box. That extra spend often suits homes with multiple remotes, alarms, or keyless-entry devices.
For occasional use, a smaller pack is easier to justify. For daily household convenience, the upgrade usually shows up in fewer restocks and less drawer digging.
Frequently Asked Questions
What is a 23A 12V battery used for?
You’ll usually find it in small remotes, keyless entry devices, alarm components, and similar compact electronics. The exact fit depends on the device code printed inside the battery compartment.
Is a 23A the same as an A23?
Those labels are closely related and often used for the same general battery format. You still need to check the device requirements before replacing the cell.
Can a 27A battery replace a 23A battery?
No, not in normal use, because the sizes are different and the contacts may not align correctly. Matching the exact code is the safer move.
Why do some packs include only two batteries?
Small packs fit people who only need a single replacement or one spare. They also store neatly in a drawer or glove box.
What should you check before ordering?
Check the battery code, the device type, and the pack count you actually need. That quick check avoids most wrong-size orders.
Closing Thoughts
Choosing the right 23a 12v Battery comes down to fit first, then pack count, then the brand you feel comfortable restocking later. For busy homes, the GP 20-pack stands out for sheer convenience, while the Energizer and Rayovac two-packs suit lighter use. The 27A options belong in a different lane, so the device code deserves a careful look before anything else. Once you match the size, the rest gets easy enough.
