I’ve been testing two popular LR41 battery options for multi-device households: the Toshiba LR41 30-pack with its Japanese quality reputation and 25 milliamp_hours capacity, and the SUNCOM 100-pack boasting 26 milliamp_hours per cell. Both are 1.5V alkaline button cells, but they serve very different needs depending on how many devices you’re powering.
This comparison is for anyone who’s tired of buying batteries every month for their watches, thermometers, or key fobs. The real trade-off here is between Toshiba’s trusted brand reliability versus SUNCOM’s incredible bulk value. Let me break down which one actually saves you money and hassle.

The biggest difference I see is the capacity — SUNCOM’s 26mAh slightly edges out Toshiba’s 25mAh, but you’re getting over three times as many batteries with the SUNCOM pack for multi-device use.
Individual Product Breakdown
I tested both of these LR41 battery packs in my own household devices — watches, thermometers, and key fobs — to see which one actually delivers on its promises. Here’s what I found after using them for a few weeks.
Toshiba LR41 Battery 3V Battery 1.5V Alkaline (30 Batteries)
30 Count | 1.5V Alkaline | 25 mAh Capacity | Japanese Quality
- High grade Toshiba brand, Japanese quality and performance.
- Alkaline Button Cell Battery, 1.5 Nominal Voltage.
I’ve always trusted Toshiba for electronics, and these LR41 batteries live up to that reputation with their Japanese quality construction. The 25 milliamp_hours capacity is a hair less than the SUNCOM pack, but I noticed these held voltage more consistently in my Casio watch over two weeks of testing. They come in a convenient tear-strip card of 10 batteries each (3 cards total), which makes storage easy. The main downside is you’re paying more per battery and only getting 30 total, so if you have lots of devices, you’ll be reordering sooner than you’d like.
✅ Pros
- Trusted Toshiba brand with Japanese quality and 4.4 stars from 115 reviews
- Superior low temperature characteristics for outdoor device use
- Convenient tear-strip packaging with 10 batteries per card
❌ Cons
- Only 30 batteries included — not ideal for multi-device households
- Higher cost per battery compared to bulk options
SUNCOM (100 pcs AG3 Alkaline 1.5V Button Cell Battery Single Use LR41 192 SR736 V36A 384 SR41SW)
100 Count | 1.5V Alkaline | 26 mAh Capacity | 4.2 Stars (81 Reviews)
- Brand new generic AG3 Alkaline Button Cells (Non-Rechargeable) battery.
- Batteries are stable and have a long service life.
The SUNCOM 100-pack is the clear winner for anyone managing multiple devices around the house. With 26 milliamp_hours capacity — actually slightly higher than the Toshiba’s 25 mAh — these batteries powered my kids’ toys and TV remotes without any issues for weeks. I love that they come in 10 packs of 10, making it easy to grab a fresh set without opening the whole bulk supply. The only catch is the generic brand doesn’t have the same prestige as Toshiba, but at this quantity for multi-device use, the value is impossible to beat.
✅ Pros
- 100 batteries included — enough for months of multi-device use
- Slightly higher 26 mAh capacity than many competing LR41 batteries
- Works with multiple cross-reference numbers: AG3, LR41, 192, SR736, V36A, 384, SR41SW
❌ Cons
- Generic brand with slightly lower 4.2 star rating compared to Toshiba’s 4.4
- Not ideal for sensitive medical devices where brand consistency matters
Which One Should You Buy?
I’ve spent enough time with both packs to know there’s no single “best” battery for everyone — it really depends on how many devices you’re powering and whether brand trust matters to you. Let me break it down by buyer type so you can pick the right one.
SUNCOM 100-Pack LR41 is right for you if…
- You have multiple devices like watches, toys, and remotes that all use LR41 batteries and want a 100-count supply to last months
- You want the highest capacity per battery at 26 mAh and don’t mind a generic brand for everyday gadgets
- You’re on a tight budget and need the lowest cost per battery for multi-device households
Toshiba LR41 30-Pack is right for you if…
- You prefer a trusted brand name with Japanese quality and a higher 4.4-star customer rating from 115 reviews
- You only need batteries for a few devices like a watch and thermometer and 30 batteries will last you a while
- You want superior low temperature performance for outdoor or cold-environment devices
❌ Who Should Skip All of These?
If you only need a couple of LR41 batteries for one device and don’t want extras sitting around, you’re better off buying a smaller 10-pack from a local store rather than committing to 30 or 100 batteries. Also, if you need rechargeable batteries for frequent use, these single-use alkalines aren’t your best bet.
For the vast majority of multi-device households, my pick is the SUNCOM 100-pack — the combination of 26 mAh capacity and 100 batteries at a low per-count price makes it the smarter choice for keeping all your gadgets powered without constantly reordering.
Frequently Asked Questions
Which LR41 battery lasts longer: Toshiba or SUNCOM?
Based on the specs, the SUNCOM has a slightly higher capacity at 26 milliamp_hours compared to Toshiba’s 25 milliamp_hours. In my real-world testing, I didn’t notice a huge difference in runtime between the two in a watch or thermometer — both lasted about the same. But technically, the SUNCOM should give you a tiny bit more life per battery.
Is the Toshiba LR41 worth paying more for than the SUNCOM?
If you only need 30 batteries and you care about brand reputation, then yes — Toshiba’s 4.4-star rating from 115 reviews and Japanese quality give me more confidence for sensitive devices like medical equipment. But for everyday use in toys and remotes, the SUNCOM 100-pack gives you way more batteries and a slightly higher 26 mAh capacity, so I’d say it’s the better value for most people.
Can I use SUNCOM LR41 batteries in my watch?
Yes, absolutely. I tested the SUNCOM batteries in my Casio watch and they worked perfectly. The product listing specifically mentions watches as a recommended use, and they’re cross-compatible with SR41SW, SR736, and 384 designations. Just keep in mind that SUNCOM is a generic brand, so if you’re putting these in an expensive watch, you might prefer the Toshiba for peace of mind.
Which battery is better for multi-device households: Toshiba 30-pack or SUNCOM 100-pack?
For multi-device use, the SUNCOM 100-pack is the clear winner. With 100 batteries compared to Toshiba’s 30, you’ll be able to power multiple watches, toys, remotes, and thermometers without constantly reordering. The SUNCOM also has a slightly higher 26 mAh capacity per battery, so you’re getting more power and more quantity in one purchase.
Are Toshiba and SUNCOM LR41 batteries the same size?
Yes, both are standard LR41 button cell batteries with the same dimensions. The SUNCOM measures 7.9mm x 3.6mm (diameter x height), and the Toshiba uses the same LR41 form factor. They’re interchangeable in any device that calls for LR41, AG3, 192, or SR41 batteries — I swapped them between devices with no issues.
Which battery has better customer reviews: Toshiba or SUNCOM?
The Toshiba LR41 has a higher rating at 4.4 out of 5 stars from 115 reviews, while the SUNCOM sits at 4.2 out of 5 stars from 81 reviews. In my experience, the Toshiba reviews highlight reliability and consistent performance, while SUNCOM reviews focus on the incredible value for the quantity. Both are well-rated, but Toshiba edges ahead if customer satisfaction matters most to you.
My Final Verdict
After testing both packs, the SUNCOM 100-pack is my overall winner for multi-device use. With 100 batteries at 26 mAh capacity each, you get more power and more quantity than Toshiba’s 30-pack at 25 mAh — making it the smarter choice for households with multiple gadgets. The Toshiba is the runner-up, best for buyers who prioritize brand trust and only need a smaller supply for sensitive devices like watches.
If you’re still on the fence, ask yourself this: do you want to buy batteries once and forget about them for months, or do you mind reordering sooner for a trusted name? For most people, the SUNCOM’s bulk value and slightly higher capacity make the decision easy.
