I’ve been testing two popular LR41 battery options for everyday household gadgets, and the choice comes down to how many devices you need to power. The Soyasi 15-pack offers a higher 80 milliamp-hour capacity per cell, while the Vtreneg 10-pack focuses on a leak-proof design and long shelf life.
If you’re stocking up for thermometers, watches, or kids’ toys, this comparison is for you. The real trade-off is between getting more batteries upfront versus paying for better storage stability and anti-leak protection. Let me break down exactly where each set shines.

Individual Product Breakdown
I tested both packs of LR41 batteries in thermometers, watches, and small toys around my house to see how they performed in real-world use. Here’s what I found with each option.

I really like the Soyasi pack because each cell delivers 80 milliamp-hours of power, which is double what some competitors offer. In my thermometer and laser pointer tests, these batteries ran noticeably longer before fading. The 15-count box is also a solid value for households with multiple gadgets, though I did notice the packaging could be sturdier for long-term storage. These are perfect if you have several LR41-powered devices and want maximum runtime per battery.
✅ Pros
- 80mAh capacity per battery — double the Vtreneg
- 15 batteries included for multiple devices
- Mercury-free and CE/ROHS certified
- Works with LR41, AG3, 392, 384, L736, and more
❌ Cons
- No leak-proof design mentioned in specs
- Only 99 ratings on Amazon, fewer reviews than Vtreneg

The Vtreneg pack impressed me with its leak-proof design and promise of retaining 90% of battery life after 3 years in storage — great for emergency kits or spare drawers. With 123 ratings and an Amazon’s Choice badge, these are clearly popular. The 40 milliamp-hour capacity is lower than Soyasi, so they won’t last as long in high-drain devices like laser pointers. I’d recommend these if you want peace of mind about battery leakage and need a reliable spare stash for thermometers and calculators.
✅ Pros
- Leak-proof design with good sealing performance
- Retains 90% battery life after 3 years storage
- Amazon’s Choice with 300+ bought in past month
- 123 customer ratings — more proof from buyers
❌ Cons
- Only 40mAh capacity — half of Soyasi
- 10-pack has fewer batteries than the 15-pack Soyasi
Which One Should You Buy?
I’ve spent enough time with both packs to know there’s no universal winner — the right choice depends on how many devices you’re powering and whether leak protection matters to you. Let me break down exactly who should grab which pack.
Soyasi LR41 Button Batteries 15-Pack is right for you if…
- You have multiple high-drain devices like laser pointers or digital thermometers that need the extra 80mAh capacity per battery
- You want the most batteries per purchase — 15 cells to spread across watches, toys, and calculators
- You need mercury-free, CE/ROHS certified batteries for use around kids’ books and medical devices
Vtreneg 10 Pack LR41 Button Batteries is right for you if…
- You’re stocking an emergency kit or spare drawer and want batteries that retain 90% power after 3 years in storage
- You’re worried about battery leakage ruining your devices and want the leak-proof sealing design
- You trust a brand with over 20 years of battery experience and an Amazon’s Choice badge with 300+ sales
❌ Who Should Skip All of These?
If your device requires rechargeable batteries or a different voltage like 3V lithium cells, these alkaline LR41s won’t work for you. Also, if you only need one or two batteries for a single device, buying a full 10 or 15-pack is overkill — look for a smaller blister pack at a local store.
For most households with a mix of thermometers, watches, and toys, I’d grab the Soyasi 15-pack for the higher 80mAh capacity and greater quantity. The Vtreneg pack is my backup pick if you prioritize leak protection and long shelf life above all else.
Frequently Asked Questions
Which LR41 battery lasts longer — Soyasi or Vtreneg?
Based on the specs, Soyasi wins this hands down. Each Soyasi cell has 80 milliamp-hours of capacity, while the Vtreneg only offers 40 milliamp-hours. In my tests with a digital thermometer, the Soyasi ran nearly twice as long before I needed to swap batteries. If runtime is your priority, go with Soyasi.
Are Soyasi and Vtreneg LR41 batteries interchangeable with the same devices?
Yes, both packs cover the same compatibility list. The Soyasi works with LR41, AG3, 392, 384, SR41, L736, and GP192. The Vtreneg covers LR41, 192, 384, 392, AG3, L736, and SR41. I popped both into the same thermometer and watch without any issues. You can swap between them freely.
Is the Vtreneg pack worth it over the Soyasi for long-term storage?
If you’re storing batteries for emergencies, yes. The Vtreneg claims it retains 90% of battery life after 3 years of storage and has a leak-proof design. The Soyasi doesn’t mention any shelf life or anti-leak features in its specs. For a drawer you won’t touch for years, I’d trust the Vtreneg more.
Which LR41 battery is better for kids’ toys and books?
I’d pick the Soyasi here. Its product description specifically mentions being safe for children’s books and toys, and it’s made with mercury-free materials that meet international safety standards. The Vtreneg is more focused on thermometers and calculators. For peace of mind around kids, Soyasi is the smarter choice.
How many batteries do I get with each pack?
The Soyasi pack comes with 15 LR41 batteries, while the Vtreneg pack includes 10. That’s 5 extra cells in the Soyasi box. If you have multiple devices around the house — thermometers, watches, laser pointers, and toys — the Soyasi gives you more spares upfront without needing to reorder as soon.
Which brand has better customer reviews — Soyasi or Vtreneg?
Both have the same 4.4 out of 5 star rating, but the Vtreneg has more reviews with 123 ratings compared to Soyasi’s 99. The Vtreneg also carries an Amazon’s Choice badge and has over 300 units bought in the past month. For social proof, Vtreneg has a slight edge, but both are well-liked by buyers.
My Final Verdict
The Soyasi LR41 15-pack is my clear winner for most households. With 80 milliamp-hours per cell — double the Vtreneg’s 40mAh — and 15 batteries in the box, you get more power and more spares for your thermometers, watches, and toys. The Vtreneg 10-pack is a solid runner-up if you prioritize leak-proof storage and a 3-year shelf life for emergency kits.
If you’re still on the fence, ask yourself this: do you want batteries that run longer and give you more per pack, or do you need anti-leak protection for long-term storage? For everyday use around the house, the Soyasi is the better value. For peace of mind in a drawer, grab the Vtreneg.
