POWEROWL High Capacity LR44 Batteries 40 Pack, L1154F AG13 357 303 SR44 A76 Premium Alkaline Battery 1.5V Button Coin Cell Batteries

Why I keep a 40-pack of LR44s in the drawer

Between kids’ sound books, LED decorations, digital calipers, and a couple of quartz watches, I burn through LR44-sized button cells more than I’d like to admit. Buying them in twos at a hardware store is a quick way to overspend, so I switched to the Powerowl LR44 batteries in a bulk 40-pack. After several months of mixed use, they’ve become my default choice for day-to-day gadgets that call for LR44, A76, or 357-sized cells.

This is an alkaline chemistry pack, rated at 1.5V per cell, with the usual footprint for the LR44 family. Powerowl leans on a higher-density cell design and an improved seal to extend life and reduce self-discharge. Marketing claims aside, what matters is how they hold up in real devices—and in my experience, they’ve performed reliably across a range of low- to moderate-drain uses.

Packaging, labeling, and storage

The 40 cells arrive on perforated blister cards that are easy to cut down as you go, which is surprisingly useful. I’ll slice off a strip of four and tuck the rest back in the box; it keeps the junk drawer from turning into a loose battery graveyard. Each battery is clearly labeled “LR44” and “1.5V,” and the packaging lists a broad set of cross-refs (LR44, A76, 357, L1154, AG13, SR44, etc.). More on compatibility in a moment.

The pack is compact and tidy enough that throwing a few spares in a toolbox or glovebox isn’t a hassle. For home storage, a cool, dry spot does the trick. I leave unopened cards sealed until needed to minimize exposure to humidity—simple, but it helps preserve shelf life with alkaline coin cells.

Everyday performance

Here’s where the Powerowl cells have impressed me:

• Toys and sound books: These are classic LR44 territory—short bursts of audio with long idle periods. A fresh pair of Powerowls keeps volume steady for weeks of heavy use. They handle intermittent drain well without fading to a whisper after a few days.

• LED decorations: Everything from tea lights to seasonal ornaments runs fine. I’ve had sets lit for several evenings in a row without obvious dimming. For static LEDs, alkalines hold up as expected.

• Digital calipers and small measuring tools: Calipers are picky about voltage dips. With a single Powerowl cell, mine zeroed consistently and stayed responsive. No random resets or flicker.

• Watches: In quartz watches that specify LR44 or allow alkaline alternatives, these cells work as expected. If your watch is tolerant of alkaline chemistry, a single battery swap is quick and uneventful.

Across a handful of devices, I’ve seen consistent, predictable behavior. Fresh cells measure around 1.6V open-circuit, and I haven’t encountered a dud out of the pack. Just as important, I’ve had no leakage issues—something that can quietly ruin a small device. After months in toys and ornaments, the battery bays were clean.

The alkaline vs. silver-oxide question

It’s worth clarifying chemistry, because this is where LR44 batteries can get confusing. LR44 is an alkaline 1.5V cell. SR44 (often labeled 357/303) is a silver-oxide 1.55V cell. Many devices list both in their documentation or on the battery cover because they share physical dimensions.

• Alkaline (LR44): Lower cost, widely available, voltage tends to sag more under load as the cell discharges. Ideal for low- to moderate-drain gadgets.

• Silver-oxide (SR44/357): Higher price, flatter discharge curve, better for precision devices that demand stable voltage (some older cameras, certain medical instruments, or exacting measuring tools).

Powerowl’s pack is alkaline. If your device explicitly calls for SR44 for accuracy-critical performance, stick with silver-oxide. If it lists LR44/A76 or treats SR44 as optional, these Powerowls are a sensible, budget-friendly choice. In many household gadgets, you’ll never notice the difference—except in your wallet.

One important caution: some compatibility charts online list “675” alongside LR44. Size-wise they’re similar, but 675 is a zinc-air hearing aid battery with different behavior and air-flow requirements. Don’t swap a 675 into an LR44 device or vice versa.

Multi-cell devices and battery swaps

A lot of gadgets take two to four LR44s in series. A couple of practical tips:

• Replace the full set together. Mixing old and new cells drags the pack down and can cause strange behavior.

• Check polarity carefully. In tight coin-cell stacks, it’s easy to flip one by mistake.

• Clean contacts. A cotton swab with a drop of isopropyl alcohol removes the oxidation that builds up in battery tubes and trays.

Following those steps, I had zero power hiccups in ornaments and children’s books that pull two or three cells at a time.

Longevity and shelf life

Powerowl cites a denser cell and better sealing to reduce self-discharge. I can’t verify the exact percentage gains, but the results were practical: the spares I opened months after the initial batch still measured strong, and devices left idle powered right up when revisited. For an alkaline button cell, that’s what I want—predictability and no mess.

Alkalines do lose voltage on the shelf over time, so if you don’t burn through LR44s regularly, consider whether a 40-pack is overkill. For my household, the pack size hits a sweet spot: generous enough that I’m not rationing, but not so large that I worry about aging out before I use them.

Value and quality control

The per-cell cost is the strongest argument for this pack. If you’re replacing two to four batteries at a time, bulk pricing matters. In return for the lower cost, you’re not giving up those basics that matter: consistent open-circuit voltage, clean packaging, and no leakers in my sample. I also appreciate that the cards are easy to portion out; some budget packs use giant unperforated sheets that are a pain to manage.

Powerowl includes a 24-month support window. I haven’t needed to use it, but it’s good to see for a consumable.

Safety and disposal

Two reminders that are worth repeating with button cells:

• Keep spares and spent cells out of reach of children and pets. Coin cells are a serious ingestion hazard.

• Tape the terminals of used batteries before disposal to prevent shorting, then recycle through a local e‑waste or battery collection program. Check your municipality’s guidance for button cells.

Even though these are standard alkaline chemistry, treating them carefully prolongs device life and keeps your bin safer.

Where these batteries make sense—and where they don’t

Use these if you need a reliable, affordable LR44 for:

• Toys, sound books, and novelty gadgets
• LED decorations and small flashers
• Calculators, laser pointers, and remotes that list LR44/A76
• Digital calipers and non-critical measuring tools

Consider silver-oxide instead if you’re powering:

• Precision equipment that specifies SR44/357 for stable voltage
• Older film cameras or light meters sensitive to voltage sag
• Certain medical instruments where manufacturer guidance favors SR44

That distinction is less about this brand and more about the underlying chemistry; as an alkaline LR44, the Powerowl pack does what it should.

The bottom line

The Powerowl LR44 pack has earned a permanent spot in my household kit. It delivers consistent, leak-free performance for the everyday devices that chew through LR44-sized cells, and the bulk format keeps the per-cell cost reasonable. The packaging is practical, the labeling is clear, and the cells have behaved predictably across toys, ornaments, calipers, and watches that accept alkaline chemistry.

Would I recommend it? Yes—with a common-sense caveat. If your device truly needs the flatter discharge curve of an SR44 silver-oxide cell, choose that chemistry. For everything else that lists LR44/A76 or treats them interchangeably, this pack is a dependable, good-value choice. It’s exactly what I want from a utility purchase: reliable, reasonably priced, and unremarkable in the best possible way.
