That little 23A battery is the reason your garage door opener goes silent or your ceiling fan remote stops talking to the fan. It is a tiny 12-volt cell that hides inside remotes, doorbells, and key fobs, and it always seems to die at the worst moment. This guide sorts through the most reliable Alkaline Battery 23A 12V options so you can grab the right pack and get back to pressing buttons that actually work.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
You will learn which multi-packs deliver steady 12-volt power, which ones prioritize leak-proof safety, and how to match a cell to its device. alkaline battery 23a 12v choices mostly differ in shelf life and pack size, so here is how to pick a winner.
Our Picks at a Glance
How To Choose The Best Alkaline Battery 23A 12V
Every 23A battery delivers the same 12 volts, so the real differences hide in how long they hold that charge and how safely they sit inside your gear. You want a cell that stays fresh on the shelf and refuses to leak corrosive fluid into a remote you plan to keep for years.
Match the voltage to the device
This is a 12-volt cell, not a standard AA or AAA. It powers small gadgets like garage door openers, ceiling fan remotes, doorbells, and car alarm key fobs. Check that your device actually calls for a 23A or A23 before buying, because the size and voltage are specific to this format.
Decode the compatible model codes
Manufacturers slap different names on the same physical cell. A battery labeled A23, 23AE, MN21, or L1028 is functionally the same 12-volt alkaline cell. When a pack lists a long string of compatible codes, it means the dimensions and voltage match all those devices, so you can trust it across your whole drawer of remotes.
Prioritize shelf life for spares
Most people buy a multi-pack and store the extras. A longer shelf life means the spares still hold a full charge when you finally need them months later. Look for low self-discharge technology and a printed manufacture date so you are not buying old stock that dies fast.

In‑Depth Reviews
1. Rayovac Size 23A 12V 1 Pack Electronic Alkaline Batteries
Our pick — over 4.5★ from 600+ verified ratings; the strongest balance of quality and price.
The name-brand single cell that remote owners reach for first
Rayovac earns the top spot because it is the cell people trust when a remote quits. Buyers report it is “exactly what I needed to replace the A23 battery on an LED lamp remote control,” and the brand’s longevity reputation keeps them coming back. It is a one-cell purchase at 0.43 ounces, so this is for the person who needs one working battery now, not a drawer full of spares.
What wins people over is straight-up performance — the consistent 12-volt output that gets a garage door opener or a specialty remote clicking again. The trade-off is value: this is a single battery, so the upfront cost per cell is far higher than any bulk pack. One owner even called it “way overpriced” but still noted it fit and shipped fast when they needed it urgently.
If you only own one or two devices that take a 23A, buying a single trusted cell beats stockpiling twenty you may never touch. This mid-range pick in price offers premium confidence, but the catch is mixed feedback on how long it actually lasts — some say years on a remote, others keep their expectations modest.
Why It Wins the Top Spot
- Performance is the top-praised aspect, with reliable 12V output for remotes
- Brand trust drives repeat purchases for specialty battery sizes
- Compact single-cell format at 0.43 oz fits any remote compartment
- Works for LED lamp remotes, garage door openers, and similar gadgets
The Honest Trade-Offs
- Single-cell purchase means the highest cost per battery
- Battery life gets mixed feedback — some last years, some less
- Value for money is a recurring debate among owners
Reach for it if: you want one dependable, name-brand cell for a single remote and you are not worried about bulk savings.
Look elsewhere if: you have multiple devices and want the lowest cost per cell, because a multi-pack will stretch your dollar much further.
2. PKCELL A23 23A 12V Alkaline Battery 12V Specialty 23AE Battery (10 Count)
A ten-pack that fixes multiple dead remotes without breaking the budget
PKCELL lands as the value champion because it delivers ten 12-volt cells at a budget-friendly price point. The crowd favorite here is sheer affordability — buyers call it a “great price” and a “great find” for a size that is increasingly hard to locate in stores. At 7.8 g per cell, these are the lightest in this lineup, a full 13% lighter than the 8.8 g cells in the Bvgokcell pack above.
Performance is the most-praised aspect, and the reviews back it up: one owner verified 12.4V straight out of the pack and used it to fix a bike speedometer issue. The 2-year shelf life, with the manufacture date printed on the card, ensures you know exactly how fresh your stock is. Five cells are sealed per card so they do not touch each other and drain during storage.
The honest caveat is battery life — feedback is mixed on how long these actually last in daily use. One owner flagged replacing them yearly, while another said longevity is “untested” after a full year. For the price, though, swapping one out annually is hardly a hardship.
The Value Case
- 10-pack at a budget-friendly price point stretches your dollar
- Performance and battery quality are the two most-praised aspects
- 2-year shelf life with a printed manufacture date on the card
- Sealed cards keep cells from touching and draining each other
What To Keep In Mind
- Battery life gets mixed feedback, with some replacing yearly
- Lightweight 7.8 g build may feel less substantial than premium cells
Best for: households with several 23A-powered devices that want a budget-friendly way to power them all at once.
Consider the alternative if: you need cells that sit on a shelf for years before use, because the shorter 2-year shelf life is not the longest here.
3. PKUNIN A23 23A 12 Volt Battery Alkaline 23A 12V Battery for Remote 20 Pack
The 20-pack that keeps a full charge for a full decade on the shelf
PKUNIN grabs the longevity crown with a 10-year shelf life, the longest of any pack here. That is the spec that matters when you are stockpiling spares for a ceiling fan remote or a gate clicker you might not touch for months. Owners mention testing these fresh at 12.4–12.6V, which is a healthy full charge for a 12-volt cell.
Battery quality is the thing everyone raves about — it is the top-praised aspect by a wide margin, with 82 owners singling it out. The leak-proof design uses a stainless steel seal for leakage prevention and is 100% free of lead, mercury, and cadmium. One owner revived a ceiling fan remote dead for 7 years, and a garage door opener reportedly works from 3 car lengths away.
The honest catch is the flip side of that praise: battery life has a notably negative thread, with some owners reporting cells lasting only about 1.5 months in continuous use. Its 55 mAh capacity tops the Bvgokcell pack’s 52 mAh. This is the pick for people who value fresh, leak-proof spares over raw longevity in a single cell.
The Long-Life Advantage
- 10-year shelf life keeps spare cells fully charged for a decade
- Leak-proof stainless steel seal protects your devices from corrosion
- Highest capacity here at 55 mAh, beating the 52 mAh Bvgokcell pack
- Free of lead, mercury, and cadmium for safer handling
The Fair Warning
- Battery life in active use has a negative thread, with some lasting about 1.5 months
- Reliability gets mixed feedback despite strong battery quality praise
Who it suits: buyers who store spare cells for years and want maximum leak protection for expensive remotes.
Who should pass: anyone running a high-use device that drains a cell monthly, because the 1.5-month reports would mean frequent swaps.
4. A23 23A 12 Volt Battery (20-Pack), MN21/23 12V Alkaline Battery
The highest-rated bulk pack with a corrosion-resistant steel shell
Bvgokcell earns its spot with the strongest crowd approval in this lineup, and the 20-pack format makes it a serious bulk-value contender. The defining spec is the 52 mAh capacity in a corrosion-resistant steel shell that is leak and explosion-proof.
Buyers love the economy of scale — one owner called it “great bulk buy” for someone with “a lot of remotes,” and another said “big bang for your buck.” The 3-year shelf life, aided by low self-discharge technology that slows power drain while stored, keeps extras viable. The compatibility list is enormous, covering 23A, A23, MN21, L1028, and dozens more equivalent codes, so it fits any standard 23A slot.
The catch is the modest review base compared to the giants above, which makes the strong rating a touch less battle-tested. The dimensions of 6.3 x 1.97 x 0.39 inches refer to the pack, not the cell. For a household with ceiling fan remotes, car alarms, and doorbells all hungry for 23A cells, this is the set-and-forget bulk buy.
The Bulk Math
- 20-pack format at a strong price makes per-cell cost very low
- 52 mAh capacity with low self-discharge for storage
- Corrosion-resistant steel shell is leak and explosion-proof
- CE-certified and free of mercury, cadmium, and lead
The Small Print
- Smaller review base than the top picks, so the rating is less proven
- Heaviest cell at 8.8 g, which matters only for ultra-tight compartments
Reach for it if: you want maximum cells per dollar with a solid 3-year shelf life and heavy-duty corrosion protection.
Consider elsewhere if: a huge, proven review base matters more to you than slightly better bulk pricing, because the leaders above have far more owner history.
5. 30 Pack 23A A23 LR23A A23S MN21/23 L1028F Alkaline Battery 12 Volt Battery (30pcs)
Thirty fresh cells for homes where every doorbell and sensor eats 23As
JNKXIXI brings the biggest box in this roundup with 30 cells, and that sheer quantity is the whole point. This is the premium-tier pick for volume — enough spares to cover a garage door opener, car alarm remotes, a ceiling fan, a home alarm system, a doorbell, window security sensors, and a flashlight simultaneously. The value for money is the top-praised aspect, with one store manager noting heavy doorbell use in a busy shop still delivered “decent” battery life.
The spec that separates it is the 5-year shelf life, a solid middle ground between PKCELL’s 2 years and PKUNIN’s 10-year claim. Low self-discharge keeps these viable during long storage, and the 5-year manufacturer warranty backs the claim. The compatibility list matches the A23, 23A, MN21, and L1028 families, so it drops into any standard 23A slot.
Functionality earns strong praise, but battery life is the recurring mixed note — owners say it depends heavily on the device and how often it is used. The built-in care tips (avoid mixing old and new cells, store in a cool dark place) are worth heeding. For a property with many battery-hungry gadgets, thirty cells mean you simply stop thinking about 23A batteries for a long stretch.
The Volume Play
- 30-pack is the largest quantity here, covering every device at once
- 5-year shelf life with a matching 5-year manufacturer warranty
- Value for money is the most-praised aspect among owners
- Low self-discharge keeps stored cells fresh for years
The Fine Print
- Battery life varies by device, with mixed feedback on high-use gadgets
- 30 cells is overkill unless you actually have many 23A devices
Best for: anyone managing multiple properties or a home wired with many security sensors, doorbells, and remotes.
Pass on it if: you only have one remote, because thirty cells will outlive your need and take up drawer space.
6. A23 12V Alkaline 23-A replacement battery 23AE GP – 20 Pack
The trusted-brand 20-pack with a heavy casing that feels built to last
GP closes out the list as the premium-brand play, backed by the largest review base in this entire roundup. The heavy casing and snug fit get repeated praise, and function is the top aspect — one owner found the cells power Sonoff remote devices perfectly, clarifying these are 12V cells, not the similar-looking 1.5V N cells. At 7.95 g each, they sit neatly between the light PKCELL and heavy Bvgokcell.
The leak-resistant design protects devices from corrosion, and the 20-pack at a premium price point still delivers solid per-cell value. Value for money is the second most-praised aspect, with owners calling the long shelf life that retains full charge ideal for LED lights, remotes, fans, and even a helicopter. One buyer summed up the packaging quality as “premium packaging protects unused batteries.”
Battery life here is the honest mixed bag — some report cells lasting quite a while, while others note as little as a month under normal use. The premium build and brand recognition justify the higher price for buyers who trust GP. This is the pick for someone who wants an established name and a sturdy casing over the leaner budget packs.
The Premium Case
- Largest review base here, indicating broad real-world validation
- Heavy casing and snug fit praised for quality feel
- Leak-resistant design protects devices from corrosion
- Compatible with A23, 23AE, MN21, V23GA, and more codes
What Owners Flag
- Battery life is mixed, with some reporting about a month in high-use devices
- Premium price point is higher than budget multi-packs
Who it fits: buyers who want an established brand name and a rugged, leak-resistant casing they can trust in expensive gear.
Who might skip: strict budget shoppers, because the premium pricing buys the brand and build more than extra capacity.
Understanding the Specs
Capacity (mAh)
Milliamp-hours (mAh) measures how much energy the cell holds, and it tells you how long a remote keeps working before the voltage drops. The PKUNIN pack leads this list at 55 milliamp_hours, edging out the Bvgokcell at 52 milliamp_hours. For remotes that get tapped a few times a day, that gap is minor; for high-use devices, every milliamp-hour counts toward fewer swaps.
Shelf Life
Shelf life is how long an unused battery holds its charge while sitting in a drawer. The spread here runs from PKCELL’s 2 years up to PKUNIN’s 10-year claim, with JNKXIXI landing in the middle at 5 years. If you buy a 20-pack, you are storing most of it, so a longer shelf life means the spares are still fresh when you finally need them. Low self-discharge technology is what makes those longer claims possible.
