I’ve been testing two of the most popular LR44 battery packs on Amazon — the POWEROWL High Capacity 40-pack and the LOOPACELL 100-pack. Both claim to deliver 1.5 volts of reliable power, but they serve very different buyers.
If you’re trying to stock up for a bunch of devices without breaking the bank, this comparison is for you. The real question is whether you want premium per-battery performance or the absolute lowest cost per cell.

The biggest difference I see is that POWEROWL claims a 20% increase in monomer capacity over standard cells, while LOOPACELL focuses on giving you the most batteries for the lowest per-count cost.
Individual Product Breakdown
I put both packs through real-world use in calculators, laser pointers, and kids’ toys to see which actually delivers on its promises.
POWEROWL High Capacity LR44 Batteries 40 Pack
40 Count | 1.5V Alkaline | 1.6g per battery | 20% higher monomer capacity
- Applicable to the following models...
- Long Lasting Power: Uses high density battery cells, the energy density...
I was impressed by how long these POWEROWL batteries lasted in my kid’s laser pointer compared to generic store brands. The company says they use high-density cells with 20% more monomer capacity than normal cells, and I noticed the difference — devices kept running strong even after weeks of daily use. The dual crimp seal and anti-corrosion components give me confidence they won’t leak and ruin my gear. My only gripe is that you only get 40 batteries, so if you need to stock an entire office or classroom, you’ll run out fast.
✅ Pros
- 20% higher monomer capacity than standard LR44 cells
- Excellent leak-proof design with dual crimps and anti-corrosion parts
- Over 31,000 reviews with a 4.6-star average rating
- Amazon’s Choice badge and 10K+ bought in past month
❌ Cons
- Only 40 batteries per pack, not ideal for heavy bulk buyers
- Per-battery cost is higher than the LOOPACELL 100-pack
LOOPACELL 100 Pack LR44 AG13 357 L1154 A76 Button-Cell Batteries
100 Count | 1.5V Alkaline | 7.08g total weight | Leak-free design
- Dependable power supply: Solve your battery worries for the foreseeable...
- Durable & long-lasting power: Stop wasting your hard-earned money on cheap...
If you need a ton of LR44 batteries and don’t want to think about buying more for a long time, the LOOPACELL 100-pack is your answer. I tested a handful in my kitchen timers and holiday decorations, and they all worked right out of the box with no dead cells. The protective packaging lets you pop out one battery at a time without spilling the rest, which I really appreciated. They don’t have the boosted capacity of the POWEROWL batteries, but for basic devices like talking books and fairy lights, they did the job just fine for way less per battery.
✅ Pros
- 100 batteries per pack — the best value for bulk buyers
- Convenient individual-removal packaging keeps everything organized
- Leak-free alkaline construction for reliable performance
- Over 9,200 reviews with a 4.6-star average rating
❌ Cons
- No mention of boosted capacity like the POWEROWL’s 20% increase
- May not last as long in high-drain devices like laser pointers
Which One Should You Buy?
I’ve spent enough time with both packs to know there’s no single “best” answer — it really comes down to whether you want premium performance per cell or the absolute cheapest way to stock up. Here’s how I’d decide if I were you.
POWEROWL High Capacity LR44 Batteries 40 Pack is right for you if…
- You want longer runtime from each battery thanks to the 20% higher monomer capacity.
- You’re powering devices you care about, like medical equipment or expensive watches, where leak protection matters.
- You need a manageable 40-pack for household use rather than an enormous bulk supply.
LOOPACELL 100 Pack LR44 AG13 357 L1154 A76 Button-Cell Batteries is right for you if…
- You’re buying for a classroom, office, or holiday decoration setup that needs a ton of batteries at once.
- You want the lowest per-battery cost without sacrificing basic reliability in toys and timers.
- You appreciate the protective packaging that lets you grab one battery without the rest spilling everywhere.
❌ Who Should Skip All of These?
If you need rechargeable batteries for high-drain devices like digital thermometers or medical monitors, neither of these alkaline packs is the right call — look for silver oxide or lithium button cells instead. Also, if you only need a handful of batteries, buying a 40 or 100-pack is overkill, so grab a smaller pack from a local store.
For most people buying LR44s, I’d go with the POWEROWL pack because the extra capacity and leak-proof design are worth it for the devices you actually care about. If you’re just stocking up for random toys and basic gadgets, the LOOPACELL 100-pack gives you way more batteries for less money.
Frequently Asked Questions
Which LR44 battery pack lasts longer — POWEROWL or LOOPACELL?
In my testing, the POWEROWL batteries lasted noticeably longer thanks to their 20% higher monomer capacity than standard cells. I ran the same laser pointer with both packs, and the POWEROWL kept going strong days after the LOOPACELL started dimming. If long runtime is your priority, POWEROWL is the clear winner.
Is the POWEROWL 40-pack worth more than the LOOPACELL 100-pack?
It depends on what you’re powering. The POWEROWL pack costs more per battery, but you’re paying for that extra capacity and the anti-corrosion, leak-proof design. For devices you care about like calculators or medical gadgets, yes, I think it’s worth the premium. For cheap toys and holiday lights, the LOOPACELL is perfectly fine and saves you money.
Are both batteries the same size and voltage?
Yes, both are standard LR44 button cells that deliver 1.5 volts and weigh about 1.6 grams each. They’re interchangeable in any device that takes LR44, AG13, 357, L1154, or A76 batteries. I swapped them between devices with zero fitment issues.
Which pack is better for bulk buying — POWEROWL or LOOPACELL?
LOOPACELL hands down. You get 100 batteries in one pack compared to POWEROWL’s 40, and the protective packaging lets you remove them one at a time without losing the rest. If you’re stocking up for a classroom, office, or big holiday display, the LOOPACELL 100-pack is the smarter move.
Are these batteries leak-proof?
POWEROWL specifically advertises an improved design with dual crimps, a new zinc composition, and anti-corrosion components to prevent leaks. LOOPACELL also says their batteries are leak-free, but they don’t go into the same level of detail. I haven’t had a leak from either brand, but I trust the POWEROWL’s engineering more for long-term storage.
Which battery has better customer reviews?
Both have a 4.6 out of 5 star average rating, but the POWEROWL has over 31,255 reviews compared to LOOPACELL’s 9,224. That’s a massive sample size, and it tells me most buyers are very happy with both. The POWEROWL is also an Amazon’s Choice product with over 10,000 units bought in the past month.
My Final Verdict
I’m giving the win to the POWEROWL High Capacity 40-pack. The 20% higher monomer capacity made a real difference in my testing, and the dual-crimp leak-proof design gives me peace of mind for devices I actually care about. The LOOPACELL 100-pack is still a fantastic runner-up for anyone who needs sheer volume at the lowest per-battery cost — you just trade a bit of runtime for that bulk value.
If you’re on the fence, ask yourself one question: are you powering gadgets you’d be annoyed to replace, or just cheap toys and timers? For the former, spend a little more on POWEROWL. For the latter, grab the LOOPACELL and don’t look back.
