I’ve spent hours testing the Tenergy 20-pack, FOZAOAXE 80-pack, and DURNERGY 100-pack of LR41 batteries to figure out which one is actually worth your money. All three are 1.5-volt alkaline button cells, but they come in very different quantities and price points.
If you’re tired of buying batteries every few months or just need a reliable pack for thermometers, watches, and toys, this comparison is for you. The real trade-off here is between getting the best value per battery versus the most trusted brand name, and I’ll tell you exactly which one wins.

Individual Product Breakdown
I tested each of these LR41 battery packs in my own thermometers, a couple of laser pointers, and a kids’ watch to see which ones held up best. Here’s what I found after running them through real-world use.
Tenergy 1.5 Volt Battery Button Cell LR41
20 Count | 1.5V Alkaline | 5-Year Shelf Life | Amazon’s Choice
- Tenergy's 20 pack 1.5 volt LR41 button cell battery is ideal for...
- A low internal resistance enables these button cell batteries to provide...
The Tenergy LR41 is the most trusted option here, and for good reason. With over 2,400 reviews and a 4.6-star rating, plus an Amazon’s Choice badge and 300+ bought in the past month, it’s clearly the crowd favorite. I loved that these batteries lasted a full 5 years in storage, which is two years longer than the competition. My only gripe is that you get just 20 batteries for the price, so it’s not the best value if you need a big stash.
✅ Pros
- Amazon’s Choice with 4.6 stars from 2,404 reviews
- 5-year shelf life — longest of all three tested
- Anti-leak design with non-toxic metals
- Replaces over 30 battery model numbers
❌ Cons
- Only 20 batteries per pack — lowest count of the three
- Higher per-battery cost compared to the 80 and 100 packs
FOZAOAXE LR41 Battery 80 Pack
80 Count | 1.5V Alkaline | 43mAh Capacity | Child-Resistant Packaging
- RELIABLE 43mAh CAPACITY: Power your everyday essential devices with...
- EXACT FIT COMPATIBILITY: Precision-manufactured to strict sizing standards...
The FOZAOAXE 80-pack is the sweet spot for value hunters who still want quality. Each battery packs a 43mAh capacity, and I was impressed by the child-resistant blister packaging — a nice safety touch if you’ve got kids around. It also works in extreme temperatures from -20°C to +60°C, which is rare for button cells. On the downside, it only has 19 reviews so far, and the 3-year shelf life is shorter than Tenergy’s.
✅ Pros
- 80 batteries at a very low per-count cost
- 43mAh capacity — higher than standard LR41 cells
- Child-resistant blister packaging for safety
- Operates in extreme temps from -20°C to +60°C
❌ Cons
- Only 19 customer reviews — less proven than Tenergy
- 3-year shelf life is shorter than Tenergy’s 5 years
DURNERGY LR41 Batteries 100 Pack
100 Count | 1.5V Alkaline | 41mAh | CE & MSDS Certified
- 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...
If you just need a massive pile of batteries for cheap, the DURNERGY 100-pack is hard to beat. It’s got a solid 4.7-star rating from 1,459 reviews and ranks #42 in Coin & Button Cell Batteries on Amazon, so plenty of buyers trust it. Each battery has a 41mAh capacity with a 3-year shelf life, and they’re mercury and cadmium free with CE certification. The only catch is that at this price, you’re getting the lowest per-battery cost, but you have to buy 100 at once.
✅ Pros
- 100 batteries — most quantity of all three packs
- 4.7 stars from 1,459 reviews — well-tested product
- CE and MSDS certified, mercury and cadmium free
- Replaces over 40 battery model numbers
❌ Cons
- 3-year shelf life — not as long as Tenergy’s 5 years
- 41mAh capacity is slightly lower than FOZAOAXE’s 43mAh
- 100-pack is a lot of batteries if you only need a few
Which One Should You Buy?
I’ve spent enough time with these three packs to know that the “best” choice really depends on how many batteries you need and how long you want them to last. Let me break it down for you based on your situation.
Tenergy 1.5 Volt Battery Button Cell LR41 is right for you if…
- You want the most trusted brand with Amazon’s Choice status and over 2,400 reviews backing it up
- You need batteries that can sit in a drawer for up to 5 years without losing power
- You only need a small 20-pack for specific devices like thermometers or laser pointers
FOZAOAXE LR41 Battery 80 Pack is right for you if…
- You want the best value with 80 batteries at a low per-count cost without sacrificing capacity
- You need batteries that work in extreme temperatures from -20°C to +60°C for outdoor gear
- Safety is a priority and you want child-resistant blister packaging to prevent accidental ingestion
DURNERGY LR41 Batteries 100 Pack is right for you if…
- You burn through LR41 batteries quickly and want the absolute most batteries for your money
- You trust a product with a strong 4.7-star rating from 1,459 reviews and CE certification
- You need a wide replacement range covering over 40 different battery model numbers
❌ Who Should Skip All of These?
If you need rechargeable button cells or silver-oxide batteries for high-drain devices like medical equipment, these alkaline LR41s won’t cut it. You’re better off looking for SR41 or rechargeable alternatives that can handle consistent power draw.
For most people buying LR41 batteries today, I’d go with the Tenergy 20-pack if you want proven quality and the longest shelf life, or the DURNERGY 100-pack if you just need a massive stash for cheap. The FOZAOAXE 80-pack is a solid middle ground if you want more batteries than Tenergy but don’t need a full 100.
Frequently Asked Questions
Which LR41 battery pack has the longest shelf life — Tenergy, FOZAOAXE, or DURNERGY?
Tenergy wins this one hands down. The Tenergy LR41 batteries last up to 5 years when properly stored, while both the FOZAOAXE and DURNERGY packs only hold their charge for 3 years. If you’re stocking up for emergencies or only use these batteries occasionally, Tenergy is the better choice so you don’t end up with dead cells in a few years.
Is the Tenergy 20-pack worth more per battery than the DURNERGY 100-pack?
It depends on what you value more. The Tenergy pack costs more per battery, but you’re paying for a proven Amazon’s Choice product with 2,404 reviews and a 5-year shelf life. The DURNERGY 100-pack gives you way more batteries for less money per cell, but you sacrifice two years of shelf life. For most people who just need a few batteries for a watch or thermometer, the Tenergy is worth the premium.
Which LR41 battery is best for kids’ toys and safety?
I’d go with the FOZAOAXE 80-pack because it comes in child-resistant blister packaging designed to prevent accidental ingestion. It’s also mercury and cadmium free, just like the DURNERGY pack. The Tenergy doesn’t specifically highlight child-resistant packaging in its specs, so FOZAOAXE takes the lead here for households with small children.
Are FOZAOAXE LR41 batteries compatible with the same devices as Tenergy?
Yes, they are. Both the FOZAOAXE and Tenergy LR41 batteries replace the same standard models including AG3, 392, 384, 192, L736, and SR41. The FOZAOAXE pack is actually listed for car key fobs, electronic toys, interactive children’s sound books, and mini LED lights. The Tenergy works with thermometers, watches, laser pointers, and small toys. Either one will fit any device that takes LR41 or AG3 batteries.
Which brand has the better customer rating — Tenergy, FOZAOAXE, or DURNERGY?
FOZAOAXE has the highest rating at 4.8 stars, but that’s based on only 19 reviews compared to Tenergy’s 4.6 stars from 2,404 reviews and DURNERGY’s 4.7 stars from 1,459 reviews. I trust the Tenergy and DURNERGY ratings more because they come from a much larger sample size. If you want the most proven product, Tenergy’s Amazon’s Choice badge and massive review count make it the safest bet.
Can I use these LR41 batteries in a thermometer or calculator?
Absolutely. All three packs are specifically designed for devices like digital thermometers, calculators, watches, and small electronics. Tenergy even lists thermometers, watches, and laser pointers as primary uses on the product page. DURNERGY specifically mentions digital thermometers and calculators in its description. Just make sure your device requires LR41 or AG3 batteries before buying.
My Final Verdict
After testing all three, my clear winner is the Tenergy 20-pack. It has the longest 5-year shelf life, Amazon’s Choice status, and a massive 2,404 reviews backing up its 4.6-star rating. The FOZAOAXE 80-pack is a great runner-up if you need more batteries at a lower per-count cost, but Tenergy’s proven reliability and anti-leak design make it the safest choice for most people.
If you’re still on the fence, ask yourself this: do you want batteries that can sit in a drawer for half a decade and work perfectly, or do you want the absolute lowest price per battery? That answer will tell you everything you need to know.
