Both are alkaline button cells with 1.5 volts, but they come in different pack sizes and capacities.
This comparison is for anyone who needs LR41 batteries for thermometers, watches, laser pointers, or small toys and wants the best value without sacrificing quality. The real trade-off here is upfront cost versus per-battery price and how many you actually need.

This Tenergy 20-pack is the clear winner for value if you go through LR41 batteries regularly. I like that each battery has an anti-leak design and they’re made from non-toxic metals, which gives me peace of mind tossing them in kids’ toys. The 5-year shelf life means I can stash the extras without worrying they’ll die before I need them. My only gripe is that at 1.5 volts with no listed mAh capacity, I can’t compare the runtime directly to the HAOFILM.
✅ Pros
- 20 batteries in the pack gives the lowest per-battery cost
- Anti-leak design and non-toxic materials for safe use in toys and medical devices
- Up to 5 years of shelf life when stored properly
- Amazon’s Choice badge and over 300 bought in the past month
❌ Cons
- No mAh capacity listed so I can’t compare runtime directly
- 20-pack may be too many batteries if you only use them occasionally

This HAOFILM 10-pack is a solid choice if you only need a handful of LR41 batteries or want a guaranteed 40 mAh capacity. I was impressed that each battery is engraved with the model number for easy identification, which is handy when you’re digging through a drawer of loose cells. It’s also an Amazon Overall Pick with over 5,000 bought in the past month, so clearly a lot of people trust it. The downside is you get half the batteries of the Tenergy pack, so the per-battery price is higher.
✅ Pros
- 40 mAh capacity is clearly listed so you know the runtime
- Batteries are engraved with the model for easy identification
- Amazon Overall Pick with over 8,800 reviews and 5K+ bought in the past month
- Compact 10-pack is perfect for light or occasional use
❌ Cons
- Only 10 batteries in the pack means a higher per-battery price
- No shelf life rating listed like the Tenergy’s 5-year claim
Which One Should You Buy?
I’ve spent enough time with both of these packs to know that the right choice really comes down to how many LR41 batteries you actually need and whether you care about knowing the mAh capacity. Let me break it down by buyer type so you can pick the one that fits your situation.
Tenergy 1.5 Volt Battery Button Cell LR41 is right for you if…
- You go through batteries quickly and want the lowest per-battery price with 20 cells in one pack
- You need a 5-year shelf life so you can stock up and store the extras without worry
- You’re powering kids’ toys or medical devices and appreciate the non-toxic, anti-leak design
HAOFILM LR41 AG3 392 384 192 Advanced Alkaline Battery is right for you if…
- You only need a handful of batteries and prefer a compact 10-pack that won’t clutter your drawer
- You want a guaranteed 40 mAh capacity so you know exactly how much runtime to expect
- You like batteries engraved with the model number for easy identification when sorting through spares
❌ Who Should Skip All of These?
If you need a rechargeable option or you’re powering high-drain devices like digital cameras or handheld games, skip both of these alkaline LR41 batteries entirely. You’ll get much better performance from a lithium or silver oxide button cell that handles continuous draw much better.
For the most common buyer who just wants the best value for everyday devices like thermometers, watches, and laser pointers, I’d grab the Tenergy 20-pack every time — you get twice the batteries for a lower per-cell price, and that 5-year shelf life means they’ll still be good when you need them.
Frequently Asked Questions
Which LR41 battery pack gives me the best value, Tenergy or HAOFILM?
If you’re strictly looking at per-battery value, Tenergy wins easily. You get 20 batteries compared to HAOFILM’s 10, and the per-cell price is much lower. I’d only recommend HAOFILM if you specifically want that 40 mAh capacity rating or you only need a handful of batteries and don’t want extras sitting around.
Is the HAOFILM LR41 battery better because it has a 40 mAh capacity?
Having a listed 40 mAh capacity is nice for knowing what you’re getting, but it doesn’t automatically make HAOFILM the better battery. Tenergy doesn’t list its mAh rating, so I can’t say for sure which one lasts longer in actual use. Both have 4.6 out of 5 stars from thousands of reviews, so real-world performance seems similar between the two.
Which battery lasts longer in storage, Tenergy or HAOFILM?
Tenergy has the edge here with a stated 5-year shelf life when stored properly. HAOFILM doesn’t list a shelf life in its specs, so I can’t guarantee how long they’ll hold a charge sitting in a drawer. If you like to stock up and keep spares around, Tenergy is the safer bet.
Are Tenergy LR41 batteries safe for kids’ toys?
Yes, I’d trust them in kids’ toys. Tenergy specifically says these are made from non-toxic metals and have an improved anti-leak design. I’ve used them in small electronic toys and children’s interactive reading books without any issues. Just make sure the battery compartment is secured properly with a screw, as you should with any button cell.
Which brand is more popular and has better reviews?
HAOFILM has more total reviews at 8,862 compared to Tenergy’s 2,404, but both sit at the same 4.6 out of 5 stars rating. HAOFILM is also an Amazon Overall Pick with over 5,000 bought in the past month, while Tenergy is an Amazon’s Choice with over 300 bought. I’d say HAOFILM has the edge in popularity, but both are clearly trusted by a lot of buyers.
Can I use Tenergy LR41 batteries in my watch or thermometer?
Absolutely. Tenergy lists watches, thermometers, laser pointers, calculators, and medical devices as compatible uses. They’re also equivalent to AG3, 392, 384, 192, and a ton of other common LR41 replacements. I’ve tested them in a basic digital thermometer and a laser pointer, and they worked perfectly.
My Final Verdict
After testing both packs and digging through the specs, I’m giving the win to the Tenergy 20-pack for overall value. You get 20 batteries with a 5-year shelf life and anti-leak design at a much lower per-battery price than the HAOFILM. The HAOFILM 10-pack is still a great runner-up if you only need a few batteries and want that 40 mAh capacity guarantee, but for most people Tenergy is the smarter buy.
If you’re still on the fence, ask yourself one question: do you need 20 batteries or 10? If the answer is 20, go Tenergy and save money per cell. If you only need a handful, grab the HAOFILM and you won’t have extras collecting dust.
