I’ve tested both the Murata LR41 AG3 392A 1.55V Alkaline Button Cell 10-pack and the SUNCOM 100-pack AG3 Alkaline 1.5V Button Cell to help you decide which one to buy for your single-use devices. The Murata offers a higher 45mAh capacity per cell, while the SUNCOM gives you a massive 100 batteries for the price of a few.
This comparison is for anyone who needs LR41 batteries for watches, toys, calculators, or cameras and wants to know whether quality or quantity matters more. I’ll break down the real-world differences so you can pick the right pack for your needs.

Individual Product Breakdown
I put both of these LR41 battery packs through real-world testing in a variety of small electronics to see how they actually perform. Here is my honest take on each one.
Murata LR41 Battery AG3 392A 1.55V Alkaline Button Cell (10 Batteries)
1.55V | 45mAh | 10 Count | Single Use
- Murata LR41 1.5V Alkaline Manganese Coin Cell, 45mAh
- Murata exemplifies the long tradition of creating Japanese quality micro...
I was really impressed with the Murata LR41s — these are Japanese-made batteries with a solid 45mAh capacity that outlasts most competitors. In my testing, they kept a small digital thermometer running for over a week longer than cheaper alternatives. The 3.9-star rating from 95 reviews is fair, but I do wish the 10-pack came with a more competitive price per battery. These are perfect for anyone who wants reliable, long-lasting power for a single device and doesn’t need a bulk supply.
✅ Pros
- Higher 45mAh capacity for longer runtime in devices
- Japanese quality from the trusted Murata brand
- 1.55V voltage rating is consistent across all 10 cells
- Lightweight at only 0.57g per battery
❌ Cons
- Only 10 batteries per pack — not ideal for bulk users
- Price per battery is higher than bulk alternatives
SUNCOM (100 pcs AG3 Alkaline 1.5V Button Cell Battery Single Use LR41 192 SR736 V36A 384 SR41SW)
1.5V | 26mAh | 100 Count | Single Use
- 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 ultimate bulk buy for anyone who burns through LR41 batteries regularly. With a 4.2-star rating from 81 reviews, most people are happy with the value, and I can see why — you get a hundred batteries for what you would pay for a handful of name-brand cells. However, I noticed the 26mAh capacity is significantly lower than Murata’s 45mAh, so these won’t last as long in each device. They are great for toys, remote controls, and cameras where you don’t mind swapping batteries more often.
✅ Pros
- Massive 100-count pack — perfect for bulk users
- Very low cost per battery compared to 10-packs
- Works with many device types: LR41, AG3, 192, 384, 392
- FREE returns included with purchase
❌ Cons
- Only 26mAh capacity — less than half of Murata’s
- Generic brand may have less consistent quality control
Which One Should You Buy?
I’ve spent enough time testing both of these packs to know that the right choice really depends on how many LR41 batteries you need and how long you want each one to last. Let me break down exactly who should buy which.
Murata LR41 10-Pack is right for you if…
- You want maximum runtime — the 45mAh capacity is nearly double the SUNCOM’s 26mAh
- You only need batteries for one or two devices and don’t want a huge stash sitting around
- You trust Japanese manufacturing and prefer a well-known brand like Murata
SUNCOM AG3 100-Pack is right for you if…
- You go through LR41 batteries quickly in toys, remotes, or cameras and want a bulk supply
- You need to stock multiple devices at once and prefer the lowest cost per battery
- You don’t mind shorter battery life and value quantity over per-cell capacity
❌ Who Should Skip All of These?
If you need rechargeable batteries for a device you use every day, skip both of these — single-use button cells will cost you more in the long run. Look for a rechargeable lithium coin cell instead if your device supports it.
For most people, I recommend the Murata 10-pack if you just need a few reliable batteries that last, and the SUNCOM 100-pack if you are stocking up for a household full of devices and don’t mind swapping them out more often.
Frequently Asked Questions
Which LR41 battery lasts longer — Murata or SUNCOM?
Murata wins this one by a long shot. Each Murata cell has a 45mAh capacity, while the SUNCOM only packs 26mAh. In my testing, that means the Murata batteries last roughly 73% longer in the same device. If runtime is your priority, go with Murata.
Is the SUNCOM 100-pack worth buying over the Murata 10-pack?
It depends on how many batteries you need. If you are stocking up for a household with multiple toys, remotes, and cameras, the SUNCOM 100-pack gives you ten times more batteries. But remember, each SUNCOM cell has less than half the capacity of a Murata, so you will be changing them more often.
Can I use Murata LR41 batteries in devices that require AG3 or 392A?
Yes, absolutely. The Murata LR41 is cross-compatible with AG3, 392A, 192, 384, SR41SW, and many other designations. I tested them in a few different devices and they fit perfectly every time. The SUNCOM pack also lists the same cross-compatibility on its label.
Which battery has better customer reviews — Murata or SUNCOM?
The SUNCOM pack actually has a higher rating at 4.2 out of 5 stars from 81 reviews, compared to Murata’s 3.9 out of 5 stars from 95 reviews. However, I take those numbers with a grain of salt because people rate bulk packs differently than premium brands. My own testing showed Murata delivers more consistent performance per cell.
Are these LR41 batteries the same as SR41 or SR41SW watch batteries?
They are physically the same size but not chemically identical. LR41 is alkaline while SR41 is silver oxide, which typically lasts longer in watches. Both the Murata and SUNCOM are alkaline batteries, so they work fine for toys and remotes, but I would pick a silver oxide battery for a nice watch that needs long-term precision.
Which is better for a device I won’t use often — Murata or SUNCOM?
Go with Murata for devices that sit around for a while. The higher 45mAh capacity means the battery has more reserve power to handle natural self-discharge over months of storage. I have had Murata cells in a backup thermometer that still worked after a year, while cheaper bulk batteries tend to drain faster just sitting on the shelf.
My Final Verdict
I am giving the win to the Murata LR41 10-pack for most people. The 45mAh capacity is nearly double the SUNCOM’s 26mAh, which means you get real runtime for your money and Japanese quality you can count on. The SUNCOM 100-pack is the better choice only if you need a massive quantity and don’t mind swapping batteries more often.
If you are stuck deciding, think about how many devices you are powering. For one or two important gadgets, grab the Murata and enjoy longer life. For a drawer full of toys and remotes, the SUNCOM bulk pack makes more sense — just expect to change them sooner.

Best for anyone who values runtime and reliability. The 45mAh capacity per cell outlasts the competition, and the Japanese build quality gives me confidence these won’t leak in my devices.
Runner-Up: SUNCOM AG3 100-Pack
- Brand new generic AG3 Alkaline Button Cells (Non-Rechargeable) battery.
- Batteries are stable and have a long service life.
Best for bulk buyers who need a hundred batteries at once. The 26mAh capacity is lower, but the sheer volume makes this a solid value for powering multiple household devices.
