The two-battery format is the main limitation, but the product is especially appealing for immediate replacement rather than long-term stocking. Energizer identifies the cells as suitable for Bluetooth devices, cameras, security systems, garage door openers, and keyless entry systems. That range covers several of the most common reasons people search for 23A 12V batteries, making the pack flexible despite its small size.
The zero-mercury construction is another useful point for buyers who pay attention to material choices. It does not make the batteries disposable, but it shows that the manufacturer is addressing environmental considerations in the cell design. Buyers should still store unused cells properly and replace them according to the guidance for their devices, particularly when a remote begins sending reduced-strength signals.
This is a strong choice for a household that owns a garage door opener, key fob, or security device and wants a recognized battery brand for occasional replacement. The smaller pack is less appealing for someone maintaining many devices, but for a straightforward two-cell need, the 4.8 rating, broad compatibility, and Energizer specialization make this an easy recommendation.
Dependable Performance for Specialty Devices
Energizer describes these cells as long-lasting and reliable, which is particularly relevant for low-drain devices that depend on steady 12V power. Users can feel comfortable using them in compatible garage door openers, cameras, security systems, and keyless entry hardware.
Best Reasons to Choose This Pair
The compact pack is best suited to immediate replacement, particularly for a key fob or garage remote. Buyers maintaining numerous devices should consider one of the five-, six-, ten-, or fifty-cell options later in this guide.

The LiCB A23 23A Batteries provide a balanced choice for buyers who need more than one replacement cell and want detailed compatibility information. They hold a 4.7 rating and are supplied as a five-pack of 12V alkaline batteries. The listing emphasizes strict quality-control testing, CE and ROHS certification, and Grade A cells.
Pros
- Strong 4.7 customer rating
- Generous equivalent-model guidance
- Fresh full-charge claim
- Three-year storage life
- Useful blister packaging
Cons
- Certification descriptions may vary
- Only five batteries per pack
We may earn a commission when you buy through this link, at no additional cost to you.
A major advantage is the extensive list of equivalent model codes. The product description references designations such as 23A, A23, 23AE, V23GA, MN21, GP23A, LRV08, L1028, 8LR23, and others. That level of detail can help buyers match an unfamiliar marking on an old battery or device manual before ordering, reducing the risk of choosing the wrong format.
The stated three-year shelf life and full-charge claim make the pack practical for maintaining a household reserve. It is also listed for garage door remotes, doorbells, car alarms, burglar alarms, lighters, keyless entry controls, and toys. One detail to note is that the quality-control description refers to Grade A 27A cells, even though the product is marketed as 23A; buyers should judge the actual package and its stated A23 specifications rather than rely on that isolated wording.
This five-pack is a sensible choice for households with several 23A-powered devices, including a garage opener and multiple key fobs. It offers a useful combination of pack size, shelf-life information, and model-code guidance. Larger ten-cell options may be more economical for heavy users, but this LiCB set is easier to store and still provides several replacements at once.
Helpful Guidance for Identifying the Correct Battery
Equivalent-code lists are particularly useful when the device only shows a generic battery symbol. Confirming voltage, physical dimensions, and the printed model designation can help avoid a mismatch even when many names refer to the same cell type.
Convenient Five-Cell Household Backup
Five cells are enough to cover several common household devices while leaving room for a future replacement. The blister pack also keeps the batteries organized, which is useful for storage in a drawer, utility closet, or small parts organizer.

Cons
- Long compatibility list needs review
- Newer listing has less history
We may earn a commission when you buy through this link, at no additional cost to you.
The listing says the cells use a corrosion-resistant steel shell and are designed to be leak- and explosion-resistant. It also identifies the batteries as CE-certified and mercury-, cadmium-, and lead-free. These details make the option appealing to buyers who want the manufacturer to explain the cell design rather than simply state the chemical type and voltage.
Compatibility is another strength. The product supports a long list of 23A, A23, MN21, 21/23, MS21, GP23A, 23AE, V23GA, L1028, and other equivalent designations. It is also recommended for doorbells, garage door openers, car alarm remotes, toys, lighters, and wireless access control devices, making it relevant to both home and vehicle-related equipment.
The main trade-off is that the listing contains a long and occasionally repetitive model list, so buyers should compare the required designation rather than assume every code is interchangeable. The five-cell quantity is also smaller than the ten- and fifty-cell products. Even so, the 4.8 rating, disclosed capacity, safety-focused design, and three-year storage claim make this a convincing pick for careful buyers.
Clearer Information About Cell Construction
The stated steel shell, corrosion resistance, and leakage-oriented design provide useful reassurance for devices with sensitive battery compartments. As always, correct installation and removal of exhausted cells remain important regardless of the claimed construction.
A Balanced Five-Pack with Detailed Specs
This product is a good middle ground between small replacement packs and large assortments. Its disclosed capacity, shelf life, and equivalent-code information help buyers make a more informed comparison with competing 23A cells.

We may earn a commission when you buy through this link, at no additional cost to you.
Compatibility extends beyond key fobs to keyless entry devices, garage door openers, remote controls, toys, and similar products. That makes the six-cell quantity well matched to a household with several low-drain devices. The listing also emphasizes a heavy-duty casing for strength and safety, a useful consideration for cells that may be dropped during removal or installation.
The manufacturer states that the batteries offer high-capacity functionality for longevity, shelf life, and power delivery. It also describes them as mercury free. These claims are less numerically detailed than the three-year and five-year shelf-life figures found elsewhere in this guide, but the overall package is clearly aimed at dependable everyday use rather than premium specialty construction.
This is a strong pick for value-conscious shoppers who maintain several compatible devices and prefer a moderate reserve. It may not be the best option for someone who wants a very long documented storage life or extensive safety specifications. For routine key-fob and garage-remote replacement needs, however, six cells, a 4.7 rating, and broad device support make it especially convenient.
A Sensible Quantity for Everyday Replacements
Six cells can cover multiple key fobs, garage remotes, or doorbells without creating a large storage burden. The moderate count also makes the pack easier for households to keep in a dry location and use gradually as batteries reach the end of their service life.
Simple Protection and Broad Use
The heavy-duty casing and mercury-free description provide basic quality markers without making the product overly complicated. Its straightforward design is attractive to buyers who want clear compatibility and practical battery availability.

Cons
- Lower rating than top choices
- Bulk quantity may be unnecessary
We may earn a commission when you buy through this link, at no additional cost to you.
The manufacturing date is printed on the card, helping buyers judge the stock they are receiving instead of relying solely on a broad freshness claim. The product also states a three-year shelf life. Combined with separate packaging, those details make it more convenient for longer-term storage than a loosely grouped assortment.
Its supported applications include garage door openers, ceiling fan remotes, remote controls, doorbells, keyless entry devices, key fobs, car alarms, and lighters. The listing also explains that A23, 23A, 23AE, MN21, L1028, GP23AE, 21/23, V23GA, MS21, E23A, 8LR23, and similar models share the same dimensions and voltage.
The trade-off is quantity. Ten batteries may be more than a one-device household needs, and the 4.6 rating is slightly below the leaders in this list. Nevertheless, for a homeowner with several compatible products, a property manager, or anyone who prefers to keep a dependable spare supply, the dated card, separated cells, and three-year shelf life make this an attractive option.
Clearer Freshness and Storage Information
A printed manufacturing date helps buyers assess inventory age, while separately sealed cells reduce contact during storage. These are useful details for anyone building a small maintenance supply rather than replacing a single remote battery.
Built for Multi-Device Households
The ten-cell quantity works well for homes with several remotes, key fobs, and garage accessories. Buyers who only need one cell may find a smaller five-pack easier to use, but this set reduces the need for frequent replenishment.

We may earn a commission when you buy through this link, at no additional cost to you.
The product description highlights testing under strict quality-control standards, along with CE and ROHS certification. It also provides a long list of equivalent battery designations, including A23, 23A, 23AE, MN21, GP23A, L1028, V23GA, E23A, 8LR932, 8LR23, and others. That breadth of guidance is valuable when the required code is printed only on the original battery.
The supported-device list covers garage door openers, doorbells, car alarm remotes, burglar alarms, lighters, keyless entry access controls, and toys. As with other listings in this category, the quality-control bullet refers to Grade A 27A cells while the rest of the product information identifies the product as a 23A battery. That wording should be noted, although it does not change the stated compatibility and voltage information.
This option makes more sense for users who regularly maintain multiple compatible devices than for a single key fob. It does not provide a numeric capacity figure or a separately printed manufacturing date, so buyers prioritizing detailed freshness information may prefer another set. Even so, the ten-cell quantity, three-year shelf-life claim, and broad model compatibility make it a useful maintenance purchase.
Useful Compatibility Across Common Remotes
The range of supported devices makes the ten-pack appropriate for a home with several remotes and access controls. Checking the required model designation before ordering remains important, especially when several similarly named battery formats are sold.
A Larger Replacement Reserve
Ten cells offer more flexibility than a compact replacement pack. They are best suited to regular users who can store the extras in a dry, cool location and keep track of their freshness.

The product is described as high-power and developed for reliable specialty-device performance. Its equivalent battery types include A23, MN21, 23AF, 23AE, and V23GA, giving buyers several familiar alternatives when checking compatibility. The 21/23 labeling is particularly useful because some devices refer to the cell by that designation rather than simply A23.
One of the most meaningful features is Duracell's guarantee against defects in materials and workmanship. The listing further states that if a device is damaged because of a battery defect, the manufacturer will repair or replace it at its option. That commitment distinguishes this product from listings that focus only on voltage, capacity, and shelf life.
The four-cell pack is modest compared with the largest multipacks, but it suits a household with several key fobs, trackers, or remotes. Buyers prioritizing a long numeric storage claim may prefer products elsewhere in the guide. For those who place weight on brand confidence and device protection, however, the 4.8 rating and stated guarantee make this an excellent specialty-battery choice.
Extra Assurance Beyond the Rating
The stated defect guarantee gives the product a different kind of value from purely specification-based options. Buyers can compare the pack not only by expected device support but also by the manufacturer's stated response to a battery-related defect.
Ideal for Important Low-Drain Electronics

We may earn a commission when you buy through this link, at no additional cost to you.
Each battery is described as having short-circuit overcurrent protection and intelligent voltage surge safeguards. The listing also states that the cells contain no mercury, cadmium, or lead. While the manufacturer uses promotional language around its engineering and manufacturing process, these stated safety features still provide useful points of comparison when selecting a specialty cell.
The compatible model list is extensive, covering 23A, A23, 23AS, MN21, 21/23, MS21, GP23A, GP23AE, A23S, AG23, L1028, 8LR23, 23GA, V23GA, 23AE, and other designations. The six-battery count is also more flexible than a two- or four-pack, making it appropriate for several remotes or a household that wants a small reserve.
The principal trade-off is that the product does not provide a numeric capacity or a clearly stated shelf-life period in its supplied information. Its long-lasting positioning is also framed as a brand claim rather than a measured duration. Still, for buyers who prioritize documented safeguards, material restrictions, and broad compatibility, the 4.6-rated six-pack offers features that many standard listings do not emphasize.
Protection Features That Stand Out
Short-circuit overcurrent and voltage surge safeguards are useful differentiators in compact batteries used near sensitive electronics. These protections work alongside correct installation and timely replacement rather than making damaged or exhausted cells safe to continue using.
Flexible Size for Common Household Devices
Six batteries suit a home with multiple doorbells, remotes, or keyless entry devices. The pack is large enough to maintain a reserve but smaller than the ten- and fifty-cell alternatives, making storage and freshness easier to manage.

We may earn a commission when you buy through this link, at no additional cost to you.
Its construction features a heavy-duty casing intended to provide reliable strength and safety. The listing also describes high-capacity functionality for longevity, shelf life, and power delivery. Unlike several competitors in the guide, it does not provide a specific number of years for shelf life, so the strongest evidence available is the product's rating, established use case, and general construction claims.
Four cells offer a useful middle ground between a two-battery emergency pack and the larger multipacks. A homeowner with two key fobs and a garage remote can cover several immediate replacements, while the quantity remains small enough to store without taking up much space. The cells should still be kept in a dry location and replaced according to the device manufacturer's instructions.
This product is a practical pick for shoppers who prefer a modest, easy-to-store multipack from a familiar retail brand. It is less suitable for a property manager, installer, or business maintaining dozens of devices, where a ten- or fifty-cell option would be more convenient. For ordinary household maintenance, the 4.7 rating and focused compatibility make it a solid contender.
A Manageable Multi-Device Backup
The four-pack gives buyers several batteries without creating the inventory burden of a larger bulk purchase. It works especially well for homes with multiple keyless entry devices and garage remotes.
Straightforward Construction and Compatibility
The heavy-duty casing and clearly listed device types make this easy to evaluate at a glance. Buyers who need a documented multi-year storage period should compare products that provide that specific information.

10. Philips 23A Batteries – Extensive Bulk Supply
Philips 23A Batteries
Fifty alkaline battery cells
Up to five-year shelf life
Advanced leakage protection
Secure freshness packaging
The Philips 50-pack is the clear bulk option in this guide, intended for households, businesses, and anyone who replaces many A23 batteries over time. It has a 4.6 rating and supplies fifty 23A 12V batteries for key fobs, garage door openers, security systems, remote controls, and sensors.
Pros
- Largest pack in the guide
- Up to five-year shelf life
- Advanced leakage protection
- Secure storage packaging
- Suitable for businesses
Cons
- Excessive for single-device buyers
- Longer storage requires rotation
We may earn a commission when you buy through this link, at no additional cost to you.
The standout claim is an extended shelf life of up to five years. The product also uses secure packaging intended to preserve freshness. These features make a large pack more practical, although buyers should still store the cells properly and consider rotating older inventory before newer cells to avoid having part of the supply expire unused.
Leakage protection is the other major strength. Philips describes secure seal rings, insulation, and high-quality materials intended to prevent corrosive leakage and protect devices. As with any battery product, correct polarity, proper installation, and timely removal remain essential; protective construction cannot compensate for an incorrectly fitted or damaged cell.
Fifty batteries are excessive for someone replacing only one key fob, but they are well suited to property managers, security installers, offices, or large households with numerous remotes. The pack is less convenient than a five-cell assortment because of its size, yet the five-year shelf-life potential and leakage-protection design are meaningful advantages for planned maintenance.
Leakage Protection for Sensitive Equipment
The stated seal rings and insulation are especially relevant for garage door openers, access controls, and security devices with sensitive compartments. Batteries should still be checked periodically and removed when they are no longer needed.
Best Fit for Planned Maintenance
Fifty cells offer the strongest bulk value for organizations or large households that regularly replace specialty batteries. Individual users should choose a smaller pack to reduce the chance that stored cells reach the end of their shelf life before use.

Buying Guide – How to Choose the Best 23A 12V Batteries
Choosing a 23A 12V battery involves balancing the required format, pack quantity, compatibility, construction, storage life, and the types of devices you need to maintain. The most important step is confirming that your equipment actually calls for a 12V A23 or 23A cell.
Confirm the Required Battery Format
A23, 23A, MN21, 21/23, 23AE, V23GA, and several other designations are used for compatible 12V specialty cells. Nevertheless, the names can look deceptively similar, so buyers should check the battery compartment, device manual, or marking on the cell being replaced. The physical dimensions and nominal voltage must both match what the device expects.
Choose the battery using the device requirement first and the model-name list second. Matching a long equivalence list does not override an incorrect size, voltage, or terminal arrangement.
Match the Pack to Usage Level
A two-pack suits an occasional replacement, while four- and five-packs cover a few common household devices. Six- and ten-packs offer more flexibility for active homes, property maintenance, or offices. A fifty-cell pack is most relevant to businesses, installers, and large households that use many compatible devices throughout the year.
Avoid buying more than you can realistically use before the batteries age in storage. The best quantity is the smallest pack that comfortably covers your current devices and expected replacement frequency.
Evaluate the Stated Shelf Life
The listed products provide different storage information, including three-year claims for several LiCB, PKCELL, and A23 options, and an up-to-five-year claim for Philips. A longer stated shelf life is useful for reserve stock, but it should be considered alongside proper storage conditions and sensible inventory rotation.
If you plan to store extra batteries, favor clearly documented shelf life, secure packaging, and a manufacturing or freshness date where available. Use older cells first and keep replacement stock in a cool, dry place.
Consider Device Compatibility
A strong battery still fails to help if the device requires a different format. The products in this guide are commonly listed for key fobs, garage door openers, doorbells, remote controls, access systems, car alarms, GPS trackers, security equipment, and certain toys. Compatibility claims vary by brand, so compare the required model number with the listing before ordering.
For household users, identifying every compatible device helps determine the correct pack quantity. For commercial buyers, make a list of equipment types and model requirements before purchasing a bulk assortment.
Review Construction and Protection
Leak-resistant shells, heavy-duty casings, corrosion resistance, overcurrent protection, and voltage surge safeguards appear in different listings. These features can help reduce the risk of damage when batteries are handled, stored, or installed correctly. They should not be interpreted as permission to mix old and new cells or leave exhausted batteries inside a device.
Choose a product with clear installation guidance and recognized construction details. Also inspect the compartment for corrosion or residue before inserting a fresh cell, especially if the previous battery sat unused for a long period.
Check the Manufacturer's Support
Brand support can be valuable for specialty batteries because the devices using them may be inconvenient to service. Duracell provides a stated guarantee against material and workmanship defects, while other products emphasize certifications, quality-control testing, and manufacturer warranties. These terms differ and should be read carefully rather than treated as identical coverage.
Keep a record of the product and purchase date, and retain the packaging if support may be needed. A recognizable brand may also be preferable when a battery powers a security device or vehicle remote.
Compare Ratings and Specifications
Customer ratings offer a useful snapshot of buyer experience, but they should be considered alongside product details. The guide includes ratings from 4.6 to 4.8, along with differences in pack size, capacity disclosures, shelf life, and protective features. A high rating does not erase a mismatch between the battery and device.
Compare products on the factors that affect your use: the required model code, number of cells, storage duration, packaging, and application support. Treat ratings as supporting evidence rather than a substitute for compatibility.
Plan Safe Installation and Storage
These are compact cells, but they still require careful handling. Store unused batteries in their original packaging, away from heat, moisture, metal objects, and children. When a device begins responding poorly, replace all cells together when the manufacturer recommends it, and confirm polarity before closing the compartment.
Proper care extends the useful buying decision by reducing accidental damage and avoidable waste. Remove exhausted batteries from devices that are not in regular use, especially if a backup battery is not being monitored.
How to Use and Care for Your 23A 12V Batteries
Begin by confirming that your device requires a 12V A23, 23A, or listed equivalent. Read the battery compartment for the required model, voltage, polarity, and recommended cell type. Remove the old battery carefully, note the orientation, and inspect the compartment for dirt, residue, corrosion, or a bent contact before installation.
Install the new cell with the positive and negative terminals aligned exactly as directed. Do not force a battery that does not fit, and never place an A23 12V cell in a compartment designed for a different chemistry, voltage, or size. After installation, test the device and close the compartment fully to protect the contacts.
Store unused batteries in their original packaging in a cool, dry place away from direct heat, moisture, and conductive metal. Rotate older stock to the front, replace cells when a device shows reduced range or inconsistent operation, and remove batteries from equipment that will remain unused for extended periods.
Frequently Asked Questions
Are A23 and 23A the same 12V battery?

Always confirm the device's required size, voltage, and model marking before buying, especially when a listing includes many alternative names.
Can I use an A23 12V battery in a garage door opener?
Yes, many garage door openers are designed to use one 12V A23 or 23A cell. The listing for the product should identify the exact battery type required, and the cell must match the compartment's dimensions and polarity. Replace the battery promptly if the remote range declines or the opener responds inconsistently.
How long do 23A 12V batteries last in storage?
Shelf life varies by product, with some listings in this guide stating three years and the Philips 50-pack stating up to five years. Actual storage life depends on temperature, humidity, packaging, and cell condition. Keeping batteries cool, dry, and sealed in their original packaging helps preserve their quality.
Should I replace both batteries in a device at once?
The answer depends on the device design. If a device uses multiple cells, replacing all of them together with the same type, chemistry, voltage, and age is generally preferable. For a device that uses a single A23 battery, replacement is straightforward. Follow the device manufacturer's instructions when available.
Can a leaked A23 battery damage my remote or opener?
A leaking battery can cause corrosion and potentially damage a battery compartment or nearby electronics. Remove the cell following the device's instructions, avoid touching leaked material directly, and ventilate the area. Disposing of the damaged battery and having the compartment checked before installing a fresh one can help protect the device.
Which pack size is best for regular household use?
A four- or five-cell pack is usually convenient for a home with several key fobs, garage remotes, or access devices. Larger six- and ten-cell packs are helpful when replacement frequency is higher. Very large bulk packs make more sense for businesses, property managers, or users who can consistently use the inventory before it ages.
Do I need to match every model code listed by the manufacturer?
No. Model-code lists are provided to help identify equivalent cells, but you only need one code that matches your device's required battery. The voltage, physical dimensions, and polarity must be correct. If two codes conflict or the manual is unclear, compare the original battery and contact the device manufacturer.
Why does my new remote still have a short range?
A fresh battery does not always solve reduced range because the remote's contacts may be dirty, the buttons may be worn, or the device's receiver may have an issue. Start by testing the battery in a compatible device or checking the remote's contacts. If the problem continues, consult the remote or receiver manufacturer rather than repeatedly using spare batteries.
Final Thoughts on Choosing the Best 23A 12V Batteries
The Energizer A23 pair is the strongest all-around pick for its 4.8 rating, established brand identity, broad device support, and zero-mercury design. The Amazon Basics six-pack stands out as a practical budget choice, while the Duracell four-pack earns the premium recommendation for its recognized brand, 4.8 rating, and stated guarantee against defects.
For the remaining needs, the five- and ten-cell multipacks offer useful reserves, with the PKCELL ten-pack especially notable for separated packaging and a printed manufacturing date. Voniko emphasizes electrical safeguards, the A23 five-pack discloses capacity and construction details, and the Philips fifty-pack serves bulk maintenance needs with leakage protection and an extended stated shelf life.
Prioritize exact device compatibility, required voltage, and pack quantity before comparing finer features. Check the current listing for updated specifications, customer feedback, availability, and pricing, and purchase fresh cells from a seller with a clear return or support policy.
