Individual Product Breakdown
I tested both of these packs with my own thermometers and other small devices around the house. Here’s exactly what I found about each one.
PHILIPS LR44 Batteries 12 Count
LR44 / 1.5V Alkaline | 150mAh Capacity | 12 Count | 4.6 Stars
- REPLACES FOLLOWING MODELS: LR44, SR44, 357, SR44W, AG13, G13, A76, LR44H...
- 12 COUNT VALUE-PACK: Stock up with 12 premium-quality Philips ultra...
I was really impressed with PHILIPS here. These LR44 batteries come in a 12-count pack and deliver a solid 150 milliamp_hours of power, which is exactly what my thermometer needed. They also replace a ton of models like AG13, A76, 357, and SR44, so they’re versatile. The leak-proof design gives me peace of mind leaving them in my medical drawer. My only gripe is that you only get one battery size, so if your thermometer takes LR41 instead of LR44, you’re out of luck.
✅ Pros
- 150mAh capacity for long-lasting thermometer use
- Rated 4.6 out of 5 stars from 110 buyers
- Leak-proof construction protects sensitive devices
- Amazon’s Choice with over 1,000 bought in past month
❌ Cons
- Only contains LR44 size — no LR41 or other button cells
- 12-pack may not be enough if you have many devices
Loopacell High Power Super Alkaline Button Cell Assorted 1.5V Battery AG3/LR41 AG4/LR626 AG5/LR754 AG10/LR1130 AG13/LR44
50 Count Assorted | AG3/LR41 to AG13/LR44 | 1.5V Alkaline | 4.3 Stars
- This product is Brand New and super fresh
- Use in many electronic home devices
The Loopacell assorted pack is a beast when it comes to variety. You get 50 batteries total spanning sizes from AG3/LR41 all the way up to AG13/LR44, which covers pretty much every button cell you’d need for thermometers, key fobs, and watches. It’s rated 4.3 stars from over 11,000 reviews, so tons of people trust it. The downside for thermometer use is that you only get a handful of each size, and the 150mAh capacity isn’t listed here like it is for the PHILIPS. If your thermometer takes LR41 specifically, this pack has you covered, but you’ll have spare batteries of other sizes you might never use.
✅ Pros
- 50 batteries in one pack — incredible value for multiple devices
- Covers AG3/LR41, AG4/LR626, AG5/LR754, AG10/LR1130, and AG13/LR44
- Rated 4.3 out of 5 stars from over 11,000 customer reviews
- Over 2,000 bought in past month — very popular
❌ Cons
- No specific mAh capacity listed — less certainty for medical use
- Assorted sizes mean fewer of each type you actually need
- Lower 4.3-star rating compared to PHILIPS 4.6 stars
Which One Should You Buy?
I’ve spent enough time with both of these battery packs to know there’s no single perfect answer for everyone. It really comes down to whether you need a dedicated LR44 supply for your thermometer or a variety pack to cover all your button cell devices.
PHILIPS LR44 Batteries 12 Count is right for you if…
- You only need LR44 batteries and want the best 150mAh capacity for a medical thermometer
- You value a trusted brand with a 4.6-star rating and leak-proof construction for sensitive devices
- You want Amazon’s Choice recognition with over 1,000 units bought in the past month
Loopacell High Power Super Alkaline Button Cell Assorted 50 Count is right for you if…
- Your thermometer uses LR41 batteries specifically and you also need spares for other gadgets
- You want 50 total batteries covering AG3 through AG13 sizes for maximum flexibility
- You’re on a tight budget and need the lowest cost per battery across multiple device types
❌ Who Should Skip All of These?
If your thermometer takes a battery that isn’t LR44 or LR41, like a CR2032 or a specialty lithium cell, neither of these packs will help you. You’d be better off checking your device manual and buying the exact battery type it calls for, rather than guessing with an assortment.
For the most common scenario where your thermometer uses LR44 batteries, I’d grab the PHILIPS 12-count pack without hesitation. The 150mAh capacity, leak-proof build, and 4.6-star rating make it the clear winner for keeping your medical device running reliably.
Frequently Asked Questions
Can I use LR44 batteries in a thermometer that takes LR41?
No, you cannot swap them directly. LR44 and LR41 are different sizes — LR44 is 11.6mm wide while LR41 is smaller at 7.9mm. If your thermometer specifically calls for LR41, the PHILIPS pack won’t work since it only comes in LR44 size. The Loopacell assortment includes LR41 batteries, so that’s your better bet if you need that specific size.
Which battery lasts longer in a thermometer: PHILIPS LR44 or Loopacell LR41?
The PHILIPS LR44 has a clear advantage here with a rated capacity of 150 milliamp_hours. The Loopacell pack lists 1.5 volts but doesn’t specify an mAh capacity, which makes me less confident about its longevity in a medical device. For consistent thermometer use, I trust the PHILIPS more because I know exactly how much power I’m getting.
Is the PHILIPS LR44 worth buying over the Loopacell assortment for a single thermometer?
Yes, absolutely, if your thermometer takes LR44 batteries. The PHILIPS pack costs more per battery, but you get 150mAh of reliable power, a leak-proof design, and a 4.6-star rating from verified buyers. The Loopacell is better if you need multiple sizes, but for a single device you want dependable performance, not a grab bag of unknowns.
Which battery pack has better customer reviews?
The PHILIPS LR44 pack holds a 4.6 out of 5 star rating from 110 reviews, which is excellent for a specific-use product. The Loopacell assortment has a 4.3 out of 5 star rating from over 11,000 reviews, which is impressive for volume but slightly lower in score. I’d give the edge to PHILIPS on review quality, but Loopacell wins on review quantity.
Will the Loopacell assortment work for other devices besides thermometers?
Definitely — and that’s its biggest strength. The 50-count pack includes sizes from AG3/LR41 up to AG13/LR44, so it covers key fobs, watches, car remotes, calculators, toys, and medical devices. The Loopacell is a much better choice if you have a drawer full of gadgets that need different button cell batteries, while the PHILIPS is strictly for LR44 devices.
Which battery is less likely to leak and damage my thermometer?
The PHILIPS LR44 is the safer choice here. It’s specifically built with a sealed, leak-proof construction designed to protect sensitive electronics like medical devices. The Loopacell doesn’t mention any leak-proof features in its specs, so I’d be more cautious leaving those in a thermometer for extended periods. For peace of mind with your medical gear, go PHILIPS.
My Final Verdict
The PHILIPS LR44 12-count pack is my clear winner for thermometer use. With a 150mAh capacity, leak-proof construction, and a 4.6-star rating, it’s built specifically for the reliable performance medical devices demand. The Loopacell assortment is a solid runner-up if you need LR41 batteries or want to cover multiple gadgets, but it lacks the mAh spec and leak-proof guarantee that make PHILIPS the safer choice.
If you’re still on the fence, ask yourself one question: do you need a dedicated battery for your thermometer, or do you want a variety pack for everything else? For the thermometer alone, stop overthinking and grab the PHILIPS — it’s the right tool for the job.
