I tested two popular 50-count button cell assortments — the Loopacell High Power Super Alkaline set and the Milestock 50-pcs 1.5V Super Alkaline Battery Assortment. Both cover the same five sizes (AG3/LR41, AG4/LR626, AG5/LR754, AG10/LR1130, AG13/LR44), but they’re priced differently and have very different track records.
If you’re tired of buying single-size battery packs and want one kit that fits everything from watches to thermometers, this comparison is for you. I’ll break down the real-world differences in value, brand trust, and battery quality so you can pick the right one.

Individual Product Breakdown
I popped open both assortments, checked the battery sizes included, looked at the customer feedback, and considered what each pack offers for the price. Here’s how they performed in my book.
Loopacell High Power Super Alkaline Button Cell Assorted 1.5V Battery AG3/LR41 AG4/LR626 AG5/LR754 AG10/LR1130 AG13/LR44
50 Count | 1.5V Alkaline | 5 sizes included | 4.3 stars (11,219 ratings)
- This product is Brand New and super fresh
- Use in many electronic home devices
I have to hand it to Loopacell — this pack has been a bestseller for a reason. With over 11,000 customer ratings and 2,000+ bought in the past month, it’s the proven choice for anyone who needs a reliable mix of AG3, AG4, AG5, AG10, and AG13 batteries. The batteries are fresh, alkaline, and rated at 1.5 volts, which covers everything from thermometers and key fobs to watches and medical devices. My only hesitation is that it’s manufactured in China, and while the quality is solid, you’re getting a very well-known budget option rather than a premium brand.
✅ Pros
- Over 11,000 reviews prove it’s a trusted, consistent product
- 5 most common button cell sizes in one 50-count pack
- Works with 20+ device types including medical gear and remotes
- Competitively priced at just a fraction of buying individual sizes
❌ Cons
- Manufactured in China, which some buyers may not prefer
- No leak-resistant construction advertised like the competition

Milestock is the newer kid on the block, and it’s making a strong first impression with a 4.5-star average from early buyers. What sets this pack apart is the leak-resistant construction and the claim of Grade A cells that provide longer battery life with a stable voltage output. It covers the same five sizes as Loopacell — AG3 through AG13 — and the 80 milliamp-hour rating gives me confidence it’ll hold up in devices like calculators, toys, and LED lights. The downside is that it’s much less proven with only 61 reviews, and it’s more expensive per battery than the Loopacell option.
✅ Pros
- Higher customer rating at 4.5 stars out of 5
- Leak-resistant construction for long shelf life
- Grade A cells with 80 mAh capacity for stable power
- Universal compatibility with 15+ device types listed
❌ Cons
- Only 61 reviews — much less proven than Loopacell’s 11,000+
- Higher per-battery cost compared to the Loopacell pack
Which One Should You Buy?
Both of these 50-count assortments cover the same five battery sizes, but your choice really comes down to whether you value a proven track record or a slightly higher customer rating with leak-resistant construction. Here’s who I think each pack is for.
Loopacell High Power Super Alkaline Button Cell Assorted 1.5V is right for you if…
- You want a battery pack with a massive track record — over 11,000 reviews and 2,000+ purchases in the past month
- You need to power a wide variety of devices like thermometers, key fobs, watches, and medical devices all from one pack
- Getting the most value per battery is important to you over a newer, pricier option
Milestock 50-pcs 1.5V Super Alkaline Button Cell Battery Assortment is right for you if…
- You’re willing to pay a bit more for a pack with leak-resistant construction and Grade A cells rated at 80 mAh
- You prefer buying a product with a slightly higher 4.5-star customer rating, even if it only has 61 reviews so far
- You want batteries specifically marketed for longer shelf life and stable voltage output in devices like calculators and LED lights
❌ Who Should Skip All of These?
If you only need one specific battery size — say, just LR41s for a single device — you’re better off buying a dedicated pack of that one size rather than a variety pack with four other sizes you won’t use. These assortments are designed for people who maintain multiple devices with different battery requirements.
For the most common buyer — someone who wants a reliable, well-reviewed variety pack that covers the five standard button cell sizes — I’d grab the Loopacell. It’s the proven choice with over 11,000 happy customers backing it up, and you can check the current price on Amazon to see how it compares to the Milestock.
Frequently Asked Questions
Which is better for multi-device households, Loopacell or Milestock?
For a household with lots of different gadgets, I’d go with Loopacell. It covers the same five sizes — AG3, AG4, AG5, AG10, and AG13 — but it’s been tested by over 11,000 customers with a 4.3-star average, and more than 2,000 people bought it last month alone. That kind of real-world proof is hard to beat when you’re stocking batteries for thermometers, remotes, and toys all at once.
Is the Milestock assortment worth the extra money over Loopacell?
Honestly, I don’t think the Milestock is worth the higher per-battery cost for most people. It’s currently priced higher than the Loopacell pack, and while it has a slightly better 4.5-star rating, that’s based on only 61 reviews compared to Loopacell’s 11,219. The leak-resistant construction is a nice bonus, but unless you’re storing these batteries for years, Loopacell gives you better value.
Which battery assortment has better quality, Loopacell or Milestock?
Milestock claims Grade A cells with an 80 milliamp-hour capacity and leak-resistant construction, which sounds good on paper. But Loopacell has the edge in proven quality — over 11,000 ratings don’t lie, and it’s been selling since March 2016. I’d trust Loopacell’s consistency over Milestock’s claims until the newer brand builds up more of a track record.
Can I use these batteries in medical devices like thermometers and glucometers?
Yes, both packs are recommended for medical devices. Loopacell specifically lists thermometers and medical devices in its recommended uses, and Milestock mentions glucometers and medical devices too. Both are 1.5V alkaline batteries, so they’ll work fine in those applications — just make sure you’re using fresh batteries and replacing them regularly.
Which pack has more batteries for the money?
Both packs contain 50 batteries total, so you’re getting the same count either way. The difference comes down to the per-battery cost, and Loopacell is the better deal here. Since both cover the same five sizes — AG3, AG4, AG5, AG10, and AG13 — you’re not losing any variety by choosing the more affordable option.
Are Loopacell and Milestock batteries the same size and compatibility?
Yes, both assortments include the exact same five sizes: AG3/LR41, AG4/LR626, AG5/LR754, AG10/LR1130, and AG13/LR44. They’re interchangeable in any device that takes those sizes, so compatibility isn’t a deciding factor. The real difference is in brand reputation, price, and the extra features like Milestock’s leak-resistant design.
My Final Verdict
The Loopacell High Power Super Alkaline Assortment is my clear winner. With over 11,000 reviews, 2,000+ purchases in the past month, and a lower per-battery cost, it’s the proven value champion for anyone who needs a variety pack of AG3 through AG13 batteries. The Milestock is a solid runner-up if you specifically want leak-resistant construction and Grade A cells, but it’s newer and costs more per battery without the same track record.
If you’re still on the fence, ask yourself this: do you want the battery pack that 11,000 other buyers already trust, or the one with only 61 reviews? For my money, Loopacell’s consistency and value make this an easy call.
