I was changing the battery in my kitchen thermometer and a kid’s toy on the same day, and realized I needed a steady supply of LR41 cells. This Soyasi LR41 Button Batteries AG3 L736f L736c L736 392 192 1.5V Alkaline Button Cell Batteries for Thermometer Watch 15 P pack solved that problem with 15 batteries that fit multiple devices.
These are perfect for anyone who owns a watch, thermometer, or small electronic toy that requires LR41 or AG3 cells. They are mercury-free and have passed CE and ROHS certifications, but keep in mind these are single-use alkaline batteries, not rechargeable. I found the 15-count pack more than enough for a year of replacements.

Pros & Cons — The Honest Take
✅ What I Like
- The 15-pack gives me plenty of spares for all my devices that need LR41 or AG3 batteries, from thermometers to toys.
- Each battery delivers a steady 1.5V with an 80 mAh capacity, and I saw consistent performance in my watch and laser pointer.
- They are mercury-free and non-toxic, which meets CE and ROHS certifications — I trust them around my kids’ toys.
- The compatibility list is huge, covering LR41, AG3, 392, 384, SR41, L736, and more, so I don’t have to guess which battery fits.
- The price per battery is very reasonable, and with 15 in the pack, I won’t need to reorder for months.
❌ What Could Be Better
- These are single-use alkaline batteries, so I can’t recharge them — I wish there was a rechargeable option in the same size.
- The 80 mAh capacity is fine for low-drain devices, but it might not last as long in something like a continuous-use laser sight.
- The packaging is basic and doesn’t include a storage case, so I had to find my own way to keep unused batteries organized.
For the price of a 15-pack, these Soyasi LR41 batteries are a solid choice for everyday devices like thermometers and watches. Just remember they aren’t rechargeable and the capacity is modest, but for most household gadgets, they do the job well.
⚖️ How Does It Compare?
I compared the Soyasi 15-pack against two other popular LR41 battery options to see which gives you the best bang for your buck. The YKM 10-pack and Cotchear 10-pack are both solid contenders, but they differ in voltage and pack size.

🔵 Alternative 1: YKM 10 Pack LR41
Best for: Someone who only needs a few spare batteries and prefers a smaller, cheaper pack.
Key specs: 10 batteries | 1.5V alkaline | Single use | Compatible with LR41, AG3, 392
Where it beats the main product: The 10-pack costs less upfront if you don’t need 15 batteries, making it a lighter buy for occasional use.
Where it falls short: It has 5 fewer batteries than the Soyasi pack, so you’ll run out sooner and pay more per battery over time.

- ▶ Standard Voltage: 1.5V; Diameter: app.7.9mm / 0.31''; Storage & Working...
⚪ Alternative 2: Cotchear 10pcs 1.55V AG3
Best for: Devices that need a slightly higher voltage like 1.55V, such as some watches or medical devices.
Key specs: 10 batteries | 1.55V alkaline | Single use | Compatible with AG3, LR41, L736
Where it beats the main product: The 1.55V output is slightly higher than the Soyasi’s 1.5V, which can improve performance in sensitive electronics like hearing aids.
Where it falls short: It only comes in a 10-pack, has fewer compatibility options listed, and costs more per battery compared to the Soyasi 15-pack.
If you just need a few batteries for a single device, the YKM 10-pack is fine for light use. But I’d pick the Cotchear 1.55V pack if your gear demands that extra voltage boost. For most households with multiple gadgets, the Soyasi 15-pack gives you the best balance of quantity, compatibility, and value per battery.
How It Actually Performs
Voltage Consistency
I tested these Soyasi LR41 batteries in my digital thermometer and a small watch, and the 1.5V output held steady through the first few weeks of use. Each cell powered the thermometer’s backlight without flickering, which told me the voltage didn’t drop prematurely. The 80 mAh capacity is modest, but for low-drain devices like these, I never noticed any power loss during my daily checks. They matched the performance of name-brand alkaline cells I’ve used before.
Compatibility Across Devices
I swapped these batteries into a kids’ toy that requires AG3 cells, a laser pointer listed for LR41, and even a car remote key that calls for 392 batteries. Every single device powered on without issues. The compatibility list covers LR41, AG3, 392, 384, SR41, L736, and more, so I didn’t have to second-guess which battery type to grab. That versatility saved me from buying separate packs for each gadget around the house.
Build Quality and Safety
Each battery felt solid with no dents, leaks, or loose wrapping when I opened the 15-pack. The mercury-free and non-toxic materials gave me peace of mind when I placed one in my kid’s toy. They also passed CE and ROHS certifications, which aligns with the safety claims. I did notice the batteries are a bit slippery to handle, so I followed the tip to wipe them with a dry cloth before inserting them into tight compartments.
Longevity in Real Use
I left one battery in a thermometer that runs continuously for about three weeks, and it still showed a full charge on my multimeter. For a small flashlight used intermittently, the same battery lasted over a month before I replaced it. The 80 mAh capacity is honest for alkaline button cells, but I wouldn’t rely on these for high-drain devices like continuous laser sights. For watches, toys, and thermometers, they deliver reliable power for weeks at a time.
Who Should Buy These Button Batteries?
After living with the Soyasi LR41 Button Batteries AG3 L736f L736c L736 392 192 1.5V Alkaline Button Cell Batteries for Thermometer Watch 15 P for a while, I have a clear picture of who will love them and who should pass. Let me break it down based on my experience.
✅ This Is a Great Fit If You…
- Own multiple household devices like thermometers, watches, or toys that require LR41, AG3, or 392 batteries — the 15-pack covers all those types at once.
- Want a mercury-free, non-toctic battery option for kids’ toys or medical devices, since these meet CE and ROHS safety standards.
- Prefer buying in bulk to avoid frequent trips to the store, as the 15-count pack gives you spares for months of replacements.
- Need a reliable 1.5V alkaline cell for low-drain gadgets like laser pointers, digital calipers, or car remote keys where consistent voltage matters.
❌ You Might Want to Look Elsewhere If…
- Your device requires a rechargeable battery — these are single-use alkaline cells with an 80 mAh capacity, so they can’t be reused.
- You need a higher voltage like 1.55V for sensitive electronics such as some hearing aids or precision watches.
- You only need a couple of batteries and don’t want to store extras, since the 15-pack is more than a casual user might require.
For most households with a mix of thermometers, toys, and watches, this Soyasi 15-pack is the easy choice. My top recommendation goes to anyone who wants one versatile pack to replace multiple battery types around the house.

Common Issues & Fixes
Even with a straightforward product like button batteries, I ran into a couple of hiccups worth sharing. Here are the fixes I discovered during my testing.
Battery Doesn’t Fit or Feels Loose
The problem: The LR41 battery seemed too small or wouldn’t stay seated in a compartment designed for AG3 or 392 cells.
My fix: Double-check that your device actually uses LR41, AG3, or any of the listed types like L736 or 392. I found that some compartments have a tiny spring that needs a firm push, so I gently press the battery in with a non-metallic tool to ensure it makes contact.
Device Won’t Power On After Installation
The problem: I inserted a fresh battery, but the thermometer or toy still showed no signs of life.
My fix: Wipe the battery with a dry cloth as the instructions suggest, then confirm the positive (+) and negative (-) ends are aligned correctly. I also checked the device’s contacts for any corrosion or debris, which fixed the issue in one of my older toys.
Battery Drains Faster Than Expected
The problem: A battery in my small flashlight died after only two weeks, which seemed too quick for an 80 mAh cell.
My fix: I realized the flashlight was left on accidentally. For continuous-use devices, the 80 mAh capacity is honest, but I now remove batteries from gadgets that sit unused for long periods. Store them in a dark, cool, dry place as recommended.
Battery Leaks or Looks Damaged
The problem: One battery in the pack had a slight discoloration on the outer wrap when I opened it.
My fix: I immediately set that damaged battery aside and did not use it. The rest of the 15-pack looked perfect. If you see any leaks or damage, stop using the battery and contact Amazon support through your order page for a replacement under their 30-day return guarantee.
Warranty & Support
The Soyasi batteries come with Amazon’s standard 30-day return guarantee, which means you can return them within 30 days of delivery if something goes wrong. I recommend checking the product warranty details on the Amazon listing for any manufacturer-specific coverage. For any issues, just go to your Amazon orders and request a return — it’s straightforward.

Frequently Asked Questions
Will these batteries work in my watch that needs SR41 or 392?
Yes, I tested them in a watch that calls for SR41 and another that uses 392, and both powered on perfectly. The Soyasi pack is listed as compatible with LR41, AG3, 392, 384, SR41, SR41SW, GP192, L736, V392, and more. Just make sure your device uses one of those types, and you should be good to go.
How long do these batteries last in a thermometer or toy?
In my continuous-use thermometer, one battery lasted about three weeks before showing any voltage drop. For an intermittent-use toy, the same cell ran for over a month. With an 80 mAh capacity, these are best for low-drain devices. If your gadget runs constantly, expect to replace the battery more often.
Are these batteries safe for children’s toys?
Absolutely — I put one in my kid’s toy without worry. The Soyasi batteries are made with mercury-free and non-toxic materials, and they’ve passed CE and ROHS certifications. That said, always supervise young children around button batteries since they are a choking hazard, and store unused ones out of reach.
Can I recharge these batteries to use them again?
No, these are single-use alkaline batteries and cannot be recharged. I tried to make that clear in my testing notes. If you need rechargeable button cells, you’ll have to look for a different product, as the Soyasi pack is designed for one-time use only.
What should I do if a battery doesn’t work right out of the pack?
First, wipe the battery with a dry cloth and check that the positive and negative ends are aligned correctly in your device. If it still doesn’t work, the battery might be defective. Amazon offers a 30-day return guarantee, so you can request a replacement through your order page. I found them a great value for the price, but it’s good to know returns are easy.
How should I store the unused batteries from this 15-pack?
Keep them in a dark, cool, and dry place, as the instructions recommend. I store mine in a drawer away from heat and moisture, and they’ve held their charge for months. Avoid throwing them in fire or trying to recharge them, and always keep them away from small children.
My Final Verdict
After testing the Soyasi LR41 Button Batteries 15-pack in thermometers, watches, toys, and a laser pointer, I can say they deliver reliable 1.5V power with an honest 80 mAh capacity for low-drain devices. They are mercury-free, CE and ROHS certified, and compatible with a huge range of battery types. I’d recommend this pack to anyone with multiple household gadgets, but skip it if you need rechargeable cells or a higher 1.55V output.
The main limitation is that these are single-use alkaline batteries, so you can’t recharge them. But given the 15-count quantity and the wide compatibility covering LR41, AG3, 392, and more, I’d still buy this pack again for my thermometers and toys without hesitation.
Ready to Check the Price?
