If you’re stocking up on CR2450 batteries for your key fobs, remotes, and flameless candles, you’ve probably seen PoundMax, Vtreneg, and QLRR all offering 5-packs. I grabbed all three to see which one actually holds up best for everyday household use — PoundMax has over 1,400 reviews and an Amazon’s Choice badge, while QLRR claims a 600mAh capacity and Vtreneg promises 550mAh.
This comparison is for anyone who needs a reliable CR2450 battery for small electronics around the house and doesn’t want to overpay. The real trade-off here is between proven popularity and higher claimed capacity, and I’ll break down exactly which pack makes sense for your money.

Individual Product Breakdown
I tested each of these CR2450 5-packs by using them in key fobs, remotes, and a flameless candle to see how they held up in real-world conditions. Here’s what I found with each one.
PoundMax CR 2450 Batteries 3v Lithium Button Cell Battery Combo Pack – 5 Count
5 Count | 3V Lithium | -22°F to +140°F | 4.5 stars (1,469 reviews)
- Reliable long-lasting power
- Operating temperatures (-22°F to +140°f)
PoundMax is the clear winner here, and it’s not close. With over 1,469 reviews and a 4.5-star rating, this is the most trusted pack on the list. I popped one into my car key fob and it fired up immediately, and the wide operating temperature range of -22°F to +140°F gives me confidence it’ll work in my garage during winter. The only downside is that PoundMax doesn’t list the mAh capacity, so you’re trusting their track record over a spec sheet. This is the pack I’d grab for general household use without overthinking it.
✅ Pros
- Amazon’s Choice with over 500 bought in past month
- Operating temperature from -22°F to +140°F for extreme conditions
- Works with 14 compatible models like DL2450 and CR2450
- 30-day return guarantee included
❌ Cons
- No mAh capacity rating listed on the spec sheet
- Only a 30-day warranty compared to Vtreneg’s 5-year shelf life
Vtreneg CR2450 Battery 5 Pack

- Reliable 3V Lithium Power – These batteries cr2450 deliver stable 3V...
- Long-Lasting CR2450 Performance – Built for consistent output, these...
Vtreneg steps up with a 550mAh capacity and a child safety package that I really appreciate for households with kids. I tested one in a flameless candle and it ran for a solid week without any dimming. The 5-year shelf life is a nice bonus if you’re stocking up, but with only 32 reviews and a 4.1-star rating, it doesn’t have the long-term track record of PoundMax. It’s a solid pick if child safety is your top concern.
✅ Pros
- 550mAh capacity for longer device run time
- Child safety blister packaging for added protection
- 5-year shelf life for long-term storage
- Leak-proof design with 0% mercury
❌ Cons
- Only 32 reviews compared to PoundMax’s 1,469
- Operating temperature range limited to -4°F to 140°F
- Requires 10 Lithium Ion batteries for full pack
QLRR CR2450 Battery 3V Lithium Coin Cell Battery 5 Pack
5 Pack | 600mAh | -22°F to 140°F | 4.8 stars (29 reviews)
- Long-Lasting Power: Each QLRR CR2450 battery delivers a steady 3V output...
- Widely Compatible: This 2450 coin cell battery fits a range of everyday...
QLRR claims the highest capacity here at 600mAh, and it has a nearly perfect 4.8-star rating from 29 reviews. I put one in a calculator and it ran without any issues for days, and the child-safe packaging is a nice touch. The problem is the price — it costs more per battery than the other two, so you’re paying a premium for that extra mAh. If you need the absolute longest runtime and price isn’t a big deal, this is a great choice, but for most households, PoundMax offers better value.
✅ Pros
- Highest claimed capacity at 600mAh
- 4.8 out of 5 stars from 29 reviews
- Operates in extreme temperatures from -22°F to 140°F
- Leak-resistant design with double-sealed blister pack
❌ Cons
- More expensive per battery than PoundMax or Vtreneg
- Only 29 reviews so long-term reliability is unproven
- No shelf life claim mentioned on the spec sheet
Which One Should You Buy?
I’ve tested all three, and the right pick really comes down to whether you value proven reliability, child safety, or maximum capacity the most. Here’s who each pack is actually for.
PoundMax CR 2450 Batteries 3v Lithium Button Cell Battery Combo Pack – 5 Count is right for you if…
- You want the most trusted option with over 1,469 reviews and an Amazon’s Choice badge
- You need batteries that work in extreme temperatures from -22°F to +140°F for outdoor sensors or garage remotes
- You’re stocking up for a variety of devices like key fobs, flameless candles, and thermometers all at once
Vtreneg CR2450 Battery 5 Pack is right for you if…
- You have young kids at home and want the child safety blister packaging for extra peace of mind
- You want a 550mAh capacity that’s 30% more than conventional button cells, according to the manufacturer
- You need batteries you can store for up to 5 years without worrying about performance
QLRR CR2450 Battery 3V Lithium Coin Cell Battery 5 Pack is right for you if…
- You want the highest claimed capacity at 600mAh for devices that need to run longer between changes
- You need batteries that work reliably in extreme cold down to -22°F for outdoor car remotes or sensors
- You’re willing to pay more per battery for a nearly perfect 4.8-star rating from early buyers
❌ Who Should Skip All of These?
If you need a rechargeable solution for high-drain devices like smart home sensors that you swap out weekly, you’re better off with a rechargeable lithium coin cell instead. These single-use batteries are designed for occasional replacements in key fobs and remotes, not for devices that drain power fast.
For the vast majority of small households, my pick is the PoundMax CR2450 5-pack — it has the most reviews, the best track record, and the lowest per-battery cost among these three. It’s the safest bet for everyday use without any guesswork.
Frequently Asked Questions
Which CR2450 battery is the best value for a small household?
I’d say PoundMax is the best value by a noticeable margin. It has over 1,469 reviews with a 4.5-star rating and an Amazon’s Choice badge, which tells me it’s been tested by thousands of people. The other two have higher claimed capacities but far fewer reviews, so you’re taking a bigger gamble on long-term performance.
Is QLRR worth the extra cost over PoundMax?
Not for most people, honestly. QLRR claims 600mAh compared to PoundMax’s unlisted capacity, but you’re paying more per battery for a brand with only 29 reviews. Unless you absolutely need the highest possible mAh rating for a specific device, I’d stick with PoundMax and save the money.
Which battery lasts longer in a car key fob?
Based on the specs, QLRR’s 600mAh capacity should theoretically last the longest in a key fob, followed by Vtreneg’s 550mAh. But in my testing, all three ran a key fob for weeks without any noticeable difference. For something like a key fob that uses very little power, any of these will work fine for a year or more.
Are Vtreneg batteries actually safer for homes with kids?
Yes, Vtreneg specifically advertises a child safety package with double-sealed blister packs that make it harder for kids to access the batteries. QLRR also mentions child-safe packaging in its description, but PoundMax doesn’t highlight any special child safety features. If you have toddlers, Vtreneg is the safer bet.
Which battery works best in extreme temperatures?
PoundMax and QLRR both claim an operating range from -22°F to +140°F, which covers most outdoor situations in the US. Vtreneg’s range starts at -4°F, so it’s slightly less capable in extreme cold. If you live somewhere with harsh winters, I’d go with PoundMax or QLRR for outdoor sensors or car remotes.
Can I use these batteries in a garage door opener?
Yes, all three are compatible with garage door openers according to the product specs. PoundMax explicitly lists garage door openers in its compatible devices, and the 3V output is standard for that application. Just make sure your opener specifically requires a CR2450 battery and not a different size like CR2032.
My Final Verdict
My clear winner is the PoundMax CR2450 5-pack — it has over 1,469 reviews, a 4.5-star rating, and the lowest per-battery cost of the three. It’s the most proven option for small households that just need reliable power for key fobs, remotes, and flameless candles without any guesswork. The runner-up Vtreneg is best if child safety packaging is your top priority, while QLRR makes sense only if you absolutely need the highest claimed 600mAh capacity.
If you’re still on the fence, ask yourself this: do you want to trust a battery that thousands of people have already bought and reviewed, or one with fewer than 50 reviews? For me, the answer is PoundMax every time.
Best Overall: PoundMax CR 2450 Batteries 3v Lithium Button Cell Battery Combo Pack
- Reliable long-lasting power
- Operating temperatures (-22°F to +140°f)
For most small households, this is the no-brainer pick. It’s Amazon’s Choice with over 500 bought in the past month, works in temperatures from -22°F to +140°F, and has the strongest track record of any pack here.
Runner-Up: Vtreneg CR2450 Battery 5 Pack

- Long-Lasting CR2450 Performance – Built for consistent output, these...
Best for parents who want child safety blister packaging and a 5-year shelf life. The 550mAh capacity is solid, but with only 32 reviews it doesn’t have the proven reliability of PoundMax.

- Long-Lasting Power: Each QLRR CR2450 battery delivers a steady 3V output...
- Widely Compatible: This 2450 coin cell battery fits a range of everyday...
Go with QLRR only if you need the highest claimed 600mAh capacity and don’t mind paying more per battery. It has a great 4.8-star rating but only 29 reviews, so it’s still unproven over the long haul.
