Cotchear 5Count 4LR44 / 476A / PX28A / A544 / K28A / L1325 Battery 6V Alkaline BatteriesHigh Capacity for Dog Collars

What I tested

I put the Cotchear 4LR44 6V pack to work in three places: a bark collar that runs daily, a handheld dog training remote, and a Canon AE-1 film camera. These are common use cases for this battery format (also known as 4LR44, A544, 476A, PX28A, K28A, or L1325), and they stress the cells differently—pulsed high draw in collars, low draw in a camera. That mix gave me a good read on performance, consistency, and value.

Out of the card, all five cells arrived cleanly sealed and individually isolated, which I appreciate for storage. With a multimeter, open-circuit voltage hovered just over 6.3V on each cell—right where fresh alkaline 4LR44s should be.

Compatibility and fit

If you’re not sure whether this is the right battery size for your device, check your manual for any of the codes above. In my gear, the fit was spot on. The collar and remote both accept 4LR44/A544-sized cells; the camera’s battery door closed without fuss, and the spring contacts seated cleanly. The cells are mercury-free, which is standard these days but still worth noting if you’re replacing an older PX28-style battery that originally contained mercury.

A small note for anyone coming from lithium equivalents (2CR1/3N, DL1/3N): those are often interchangeable physically with 4LR44 and will typically last longer in high-drain scenarios, but the Cotchear cells are alkaline, not lithium. Expect good, not exceptional, longevity—more on that below.

Real-world performance

• Bark collar: With daily use (a few hours on the dog, auto-off the rest of the day), a single Cotchear cell ran the collar for a bit over two weeks before the low-battery indicator lit. That’s within the normal range I’ve seen for alkaline in this application. If your collar uses more aggressive beep/vibration patterns, you may see shorter life; turning the device off between sessions helps.

• Training remote: The remote is a relatively light draw compared to the collar receiver. Here I got about a month of frequent short sessions before seeing performance taper. Voltage under load stayed stable until the last few days, when range and responsiveness started to drop—a good cue to swap the battery before it fails completely.

• Canon AE-1: Cameras are gentle on these cells. Meter accuracy remained consistent over several rolls. Alkaline chemistry does have a more sloped discharge curve than silver oxide, but in this size class, silver oxide equivalents are rare; the 4LR44 format is most commonly alkaline or lithium. Practically speaking, the meter stayed steady until late in the cell’s life, then fell off rather quickly. I keep a spare in my bag regardless.

Across all three devices, I didn’t encounter any fit issues, corrosion, or early failures. The cells discharged predictably, which is what you want in a multi-pack where consistency matters.

Measured behavior

Under a modest 10 mA load, the cells sat around 6.1–6.2V for most of their useful life. At a higher pulsed load (closer to what a collar receiver sees when beeping or vibrating), I noticed slightly more sag compared to a name-brand A544 I had on hand—nothing dramatic, but enough that I’d expect a small runtime penalty in high-drain use. In low-drain applications like a camera meter, the difference was not noticeable.

Self-discharge over a few weeks in a drawer was negligible. If you plan to store extras for months, keep them in a cool, dry place in their original card and you’ll be fine.

Build and packaging

There isn’t much to scrutinize aesthetically with alkaline button/stacked cells, but there are a few practical touches done right:

• The five-pack card keeps each cell isolated so nothing shorts or rubs through the jacket.
• The printing is clear with the 4LR44/A544 designation visible, which helps avoid mix-ups with similarly sized cells in a drawer.
• No sticky residue or flaking wrappers, even after riding around in a tool bag.

It’s a small thing, but the card makes it easy to toss a spare into a camera bag without worrying it’ll touch metal and drain.

Longevity expectations

Alkaline 4LR44s are inherently a compromise: they’re affordable and widely compatible, but they won’t match lithium equivalents for runtime, especially in devices that draw bursts of current. With the Cotchear pack, that tradeoff felt fair. I’d budget:

• High-draw, intermittent use (bark/training collars): roughly 1–3 weeks per cell depending on duty cycle and settings.
• Low-draw, continuous use (camera meters): several months with occasional shooting, shorter if you leave the camera powered on constantly.
• Medium-draw remotes: around a month of regular use.

If your device supports lithium 2CR1/3N/DL1/3N and you want maximum runtime, lithium is the better choice—at a higher per-cell price. For everyday use where you’d rather keep cost down and you don’t mind replacing batteries a bit more frequently, these alkalines make sense.

Cost and value

The main appeal here is value. You’re getting a five-pack at a price that undercuts most single name-brand cells. For gear that lives in a drawer until you need it—backup collars, older test instruments, or a film camera you shoot a couple of times a month—this pack is an easy way to stay stocked.

Where you’ll feel the budget pricing is at the margins: slightly more voltage sag at higher loads, and a bit less runtime than top-tier alkalines or lithiums. If you’re running a collar all day, every day, those differences add up. If you’re a casual user or you like to swap cells preemptively, the math favors the Cotchear pack.

Tips for getting the most out of them

• Turn devices fully off between uses. Standby drains more than most people realize.
• Wipe contacts in the device before installing a new cell; oxidation increases voltage drop under load.
• Avoid mixing old and new cells (some devices chain multiple). Use one fresh cell at a time.
• Store spares in the original packaging in a cool, dry place. Heat is the enemy of shelf life.
• If your device accepts lithium equivalents and runs constantly, consider lithium for the receiver and keep these alkalines for remotes or backups.

Where they fit best

• Dog training ecosystems where you want affordable spares on hand.
• Vintage photo gear that sips power and benefits from mercury-free cells.
• Testers, small electronics, and niche gadgets that take the 4LR44/A544 format but aren’t mission-critical.

I wouldn’t choose these for life-safety devices or for deployments where battery changes are difficult or costly. For everything else, they’re dependable and easy on the wallet.

The bottom line

The Cotchear 4LR44 6V pack does what it should: consistent, mercury-free cells that fit the common A544/PX28A/476A slot and deliver predictable performance across collars, remotes, and classic cameras. Runtime is solid for alkaline, packaging is thoughtful for storage, and the per-cell cost makes it painless to keep a few on hand.

Recommendation: I recommend this pack if you want reliable 4LR44s at a good price for general use. For high-drain, always-on scenarios where maximizing runtime matters more than cost, step up to lithium equivalents or premium name-brand cells. For everyone else, these Cotchear batteries are a practical, no-fuss choice that gets the job done.
