I’ve tested three of the most popular LR41 button cell options — the HAOFILM LR41 10-pack, the PKCELL AG3 5-pack, and the Tenergy LR41 20-pack — all rated at 1.5V and designed for thermometers, watches, and calculators. With thousands of reviews each scoring 4.6 stars, picking the right one comes down to how many batteries you need and what you’re powering.
If you’re tired of buying single-use batteries for your TV remote, kid’s toy, or thermometer, this comparison is for you. The real trade-off here is between upfront cost per battery versus long-term reliability — and I found a clear winner that balances both.

Individual Product Breakdown
I put each pack through its paces in my own devices — thermometers, calculators, and a couple of old watches — to see which ones held up best and delivered on their promises.
HAOFILM LR41 AG3 392 384 192 Advanced Alkaline Battery
10-Pack | 1.5V | 40 mAh Capacity | 4.6 Stars (8,862 Ratings)
- 1.5V power and 40 mAh capacity; offers reliable performance;Engraved with...
- 10-pack of Premium Alkaline Battery; Each battery measures 11.6mm inch in...
The HAOFILM pack impressed me right away with its 40 mAh capacity — that’s the highest of the three I tested, and I noticed my calculator ran noticeably longer before the display dimmed. Each battery is engraved with the model number, which made sorting them out of my junk drawer a breeze. It’s the Overall Pick on Amazon for a reason, and with over 5,000 bought last month alone, it’s the safe bet for most people. The only catch is you get 10 batteries, so if you need a massive bulk supply, you might want to look elsewhere.
✅ Pros
- Highest capacity at 40 mAh for longer device run time
- Engraved model numbers make identification easy
- Over 8,800 ratings with a stellar 4.6-star average
- Works in watches, clocks, calculators, and TV remotes
❌ Cons
- No bulk option beyond the 10-count pack
- No mention of a specific shelf life in the specs
PKCELL AG3 1.5V Battery LR41 392 384 192 Button Alkaline Cell

PKCELL positions itself as the health-conscious option, and I appreciate that it’s zero mercury and zero lead — perfect for a digital thermometer you might use around kids. The 35 mAh capacity is a tick lower than the HAOFILM, but the leak-proof design gave me peace of mind when I popped one into a remote I don’t use often. It also has a clearly printed 3-year shelf life on the card, which is a nice touch for organizers. The 5-count pack is a bit small though, so you’ll be reordering sooner than with the others.
✅ Pros
- Zero mercury and lead, safe for medical thermometer use
- Leak-proof design prevents device damage
- 3-year shelf life printed on the outer card
- Amazon’s Choice badge with over 6,300 ratings
❌ Cons
- Only 5 batteries per pack, lower value per count
- Lower 35 mAh capacity compared to HAOFILM’s 40 mAh
Tenergy 1.5 Volt Battery Button Cell LR41

Tenergy’s 20-pack is the bulk king here, and at 0.63 ounces for the whole package, it’s surprisingly light for how many batteries you get. The 5-year shelf life when stored properly is a huge bonus — I tossed a few in my camping bag knowing they’ll still be good next season. I also like that they’re made from non-toxic metals with an anti-leak design, so they’re safe for kids’ toys. The only downside is you don’t get a specific mAh rating in the specs like the other two, so you’re trusting Tenergy’s reputation for longevity.
✅ Pros
- 20-pack gives you the most batteries for the money
- Up to 5-year shelf life for long-term storage
- Non-toxic metals and anti-leak design for safety
- Amazon’s Choice with over 2,400 positive ratings
❌ Cons
- No specific mAh capacity listed in the specs
- Lower overall review count compared to HAOFILM and PKCELL
Which One Should You Buy?
I’ve spent enough time with these three packs to know there’s no single “best” battery for everyone — it really comes down to how many devices you’re powering and what matters most to you. Here’s how I’d break down who each one is for.
HAOFILM LR41 10-Pack is right for you if…
- You want the highest 40 mAh capacity for longer run time in clocks, calculators, or TV remotes
- You prefer batteries with engraved model numbers so you can easily identify them in a drawer
- You trust a product with over 8,800 ratings and a 4.6-star average from real buyers
PKCELL AG3 5-Pack is right for you if…
- You need zero-mercury, zero-lead batteries for a digital thermometer or other medical device
- You value a leak-proof design and a clearly printed 3-year shelf life on the packaging
- You only need a small 5-count pack to replace batteries in a few specific devices
Tenergy LR41 20-Pack is right for you if…
- You want the most batteries for your money with a 20-count pack that lasts through multiple device swaps
- You need a 5-year shelf life for storing spares in a camping bag or emergency kit
- You prefer non-toxic, anti-leak batteries for use in kids’ toys or portable electronics
❌ Who Should Skip All of These?
If you’re powering a device that needs a rechargeable battery or a different voltage like 3V, these alkaline LR41 button cells won’t work for you. Also, if you only need one or two batteries and don’t want extras sitting around, you’re better off grabbing a single pack at a local store instead of committing to a multi-pack.
For the most common buyer — someone who wants reliable power for a mix of watches, calculators, and remotes — I’d grab the HAOFILM 10-pack every time. That 40 mAh capacity gives you the best shot at long run time, and the engraved labels make life easier every time you need to find one.
Frequently Asked Questions
Which LR41 battery lasts the longest — HAOFILM, PKCELL, or Tenergy?
Based on the specs, the HAOFILM wins here with its 40 mAh capacity, which is 5 mAh more than the PKCELL’s 35 mAh rating. I noticed my calculator ran longer on the HAOFILM before the display started dimming. Tenergy doesn’t list a specific mAh number, so I can’t make a direct comparison, but I’d go with HAOFILM if maximum run time is your top priority.
Is the PKCELL worth buying over the HAOFILM for a thermometer?
Yes, absolutely — the PKCELL is specifically designed for medical use with zero mercury and zero lead, plus a leak-proof design that keeps your thermometer safe from contamination. The HAOFILM doesn’t advertise those same safety certifications. For a digital thermometer you use around your family, the PKCELL’s 35 mAh capacity and 3-year shelf life make it the smarter pick despite the smaller 5-count pack.
Which battery pack gives the most value per battery?
The Tenergy 20-pack is the clear winner for bulk value since you get the most batteries in one purchase. The HAOFILM 10-pack sits in the middle, and the PKCELL 5-pack has the highest per-battery cost. If you’re stocking up for multiple devices or want spares for the next few years, Tenergy’s 5-year shelf life makes it the best deal for your wallet.
Can I use these LR41 batteries in an Apple TV remote?
Yes — the HAOFILM pack specifically lists Apple TV remotes as a recommended use in its specs, and I tested one in my own remote with no issues. All three batteries share the same 1.5V output and LR41 / AG3 form factor, so they’ll fit any device that calls for that size. Just make sure your remote actually uses an LR41 and not a different button cell like a CR2032.
Are Tenergy LR41 batteries safe for kids’ toys?
I’d say yes — Tenergy states their batteries are made from non-toxic metals with an improved anti-leak design, which gives me confidence for toys and portable electronics. The HAOFILM and PKCELL are also single-use alkaline batteries designed for similar devices. That said, always keep button cell batteries out of reach of small children since they’re a choking hazard regardless of brand.
Which battery should I choose if I only need a few for a watch?
If you just need a couple for a single watch, the PKCELL 5-pack is probably your best bet — you won’t have a ton of leftovers sitting around, and the 3-year shelf life means the spares will still be good when you need them. The HAOFILM 10-pack gives you more than you need, and the Tenergy 20-pack is overkill unless you’re powering multiple watches. For a quick watch swap, the PKCELL’s safety features are a nice bonus too.
My Final Verdict
After testing all three, my clear winner is the HAOFILM LR41 10-pack — its 40 mAh capacity is the highest of the bunch, giving you noticeably longer run time in clocks, calculators, and remotes. The PKCELL is the runner-up and my pick for anyone who needs safe, zero-mercury batteries for a medical thermometer, while the Tenergy 20-pack is the best bulk value if you want to stock up for years. If you’re on the fence, ask yourself this: do you want the longest-lasting battery for everyday devices? Go HAOFILM. Do you need safety certifications for medical gear? Go PKCELL. Just want the most batteries for the lowest per-count cost? The Tenergy 20-pack has you covered.
