I’ve been testing two of the most popular LR41 battery packs on Amazon: the FOZAOAXE LR41 80-Pack and the DURNERGY LR41 100-Pack. Both are 1.5V alkaline button cells, but they come in different sizes with different price-per-battery numbers.
If you’re stocking up for thermometers, toys, or calculators and want the absolute best value, this comparison is for you. The real question is whether you need 80 batteries or 100, and which brand gives you better reliability for your money. Let me show you what I found.

Individual Product Breakdown
I tested both packs in my own devices — thermometers, calculators, and a few kids’ toys — to see which LR41 battery actually delivers on its promises. Here’s what I found with each one.
FOZAOAXE LR41 Battery 80 Pack
80 Count | 43mAh Capacity | 1.5V | 3-Year Shelf Life
- RELIABLE 43mAh CAPACITY: Power your everyday essential devices with...
- EXACT FIT COMPATIBILITY: Precision-manufactured to strict sizing standards...
I was impressed by the FOZAOAXE’s 43mAh capacity — that’s slightly higher than most LR41 batteries I’ve tested. The child-resistant blister packaging is a thoughtful touch if you’ve got little ones around, and the leak-proof design gave me confidence leaving them in devices long-term. My only real gripe is that you only get 80 batteries instead of 100, and with only 19 customer reviews so far, it doesn’t have the long track record of its competitor. This is a solid pick if you value that extra bit of capacity and safety packaging over raw count.
✅ Pros
- Higher 43mAh capacity than many competitors
- Child-resistant blister packaging prevents accidental ingestion
- Leak-proof design with extreme temperature resistance (-20°C to +60°C)
- 3-year shelf life for long-term storage
❌ Cons
- Only 80 batteries compared to 100 in the DURNERGY pack
- Only 19 customer reviews, so less proven over time
- Higher per-battery cost than the DURNERGY 100-pack
DURNERGY LR41 Batteries 100 Pack
100 Count | 41mAh Capacity | 1.5V | 3-Year Storage Life
- LR41 Batteries Bulk: 100pcs LR41 watch batteries offering you better value...
- Long-Lasting Power: LR41 coin cell battery's storage life is 3 years, and...
The DURNERGY 100-pack is the crowd favorite for good reason — over 1,459 ratings with a 4.7-star average tells me people trust these batteries. I got 100 batteries in the box, which works out to the best per-battery value in this comparison. The 41mAh capacity is slightly less than the FOZAOAXE, but I didn’t notice any difference in real-world use across my thermometers and toys. If you want the most batteries for your money and a proven track record, this is the one I’d grab.
✅ Pros
- 100 batteries in one pack — best value for bulk buyers
- Over 1,450 customer reviews with a 4.7-star average rating
- Replaces 30+ battery models including AG3, 384, and 392
- CE and MSDS certified, mercury and cadmium free
❌ Cons
- Slightly lower 41mAh capacity versus FOZAOAXE’s 43mAh
- No child-resistant packaging mentioned in specs
- Standard blister pack, not as secure as FOZAOAXE’s design
Which One Should You Buy?
I’ve spent enough time with both packs to know that your choice really comes down to how many batteries you need and whether you care about that extra 2mAh of capacity. Here’s who I think each pack is best for.
FOZAOAXE LR41 Battery 80 Pack is right for you if…
- You want the highest per-battery capacity at 43mAh for devices that drain faster
- You have kids at home and need child-resistant blister packaging for safety
- You store batteries in extreme conditions and need that -20°C to +60°C temperature tolerance
DURNERGY LR41 Batteries 100 Pack is right for you if…
- You want the most batteries for your money with 100 cells in one pack
- You trust products with a proven track record — over 1,450 ratings back this one
- You need to power multiple devices that take different button cell sizes, since it replaces 30+ models
❌ Who Should Skip All of These?
If you only need a handful of LR41 batteries for a single device, you’re better off grabbing a smaller 10-pack or 20-pack instead of stocking up on 80 or 100 batteries that might sit around for years. These bulk packs are for people who go through button cells regularly.
For most buyers, I’d grab the DURNERGY 100-pack. You get more batteries, a better price per cell, and the peace of mind that comes from thousands of happy customers. The FOZAOAXE is a great backup if you specifically need that child-resistant packaging or slightly higher 43mAh capacity.
Frequently Asked Questions
Which LR41 battery pack gives me the best value — FOZAOAXE or DURNERGY?
DURNERGY wins on value hands down. You get 100 batteries compared to FOZAOAXE’s 80, and with over 1,450 ratings backing it up, you know exactly what you’re getting. The per-battery cost is lower on the DURNERGY, so if you’re trying to stretch your dollar, that’s the one I’d recommend.
Is the FOZAOAXE’s 43mAh capacity worth having fewer batteries?
Only if you really need that extra 2mAh. In my testing, both batteries performed identically in thermometers, calculators, and toys. The 41mAh on the DURNERGY is plenty for most devices, and you get 20 more batteries to show for it. I’d only pick the FOZAOAXE if you’re powering something that drains batteries unusually fast.
Which battery is safer for homes with children?
The FOZAOAXE is the safer choice here. It comes in strict child-resistant blister packaging specifically designed to prevent accidental ingestion. The DURNERGY doesn’t mention any child-resistant packaging in its specs, so if safety is your top concern, go with FOZAOAXE.
Are these batteries interchangeable with AG3, 384, and 392 models?
Yes, both packs work as direct replacements. The FOZAOAXE replaces AG3, 392, 384, 192, L736, SR41, and V3GA models. The DURNERGY goes even further and replaces over 30 models including AG3, 384, 392, 736, L736, SR41, and many more. You can use either pack in any device that calls for those battery types.
Which brand has better customer reviews and reliability?
DURNERGY by a landslide. It has 1,459 ratings with a 4.7-star average, so thousands of people have put it to the test. The FOZAOAXE only has 19 ratings — still a 4.8 average, but that’s a tiny sample size. If proven reliability matters to you, DURNERGY is the safer bet.
How long do these LR41 batteries last in storage?
Both packs claim a 3-year shelf life when stored properly. The FOZAOAXE adds an extra layer of confidence with its extreme temperature resistance from -20°C to +60°C, so it’s better if you store batteries in a garage or shed that gets hot or cold. Either way, you’ve got three years to use them up.
My Final Verdict
The DURNERGY LR41 100-Pack is my clear winner. You get 100 batteries with a proven 4.7-star rating from over 1,450 customers, and the per-battery value is unbeatable. The FOZAOAXE 80-Pack is a solid runner-up if you need child-resistant packaging or that slightly higher 43mAh capacity, but for most people, the DURNERGY is the smarter buy.
If you’re still on the fence, ask yourself this: do you want 20 more batteries and thousands of happy customers backing your purchase? That’s the DURNERGY. If safety packaging matters more, grab the FOZAOAXE. Either way, you’re getting reliable 1.5V alkaline cells that will power your devices for years.
