I’ve tested both the DURNERGY 5 Pack CR2450 and the YFCN CR2450 Battery 5 Count Pack to figure out which is the better buy for your remotes and flameless candles. The DURNERGY pack has a 600 milliamp_hours capacity and comes individually packaged, while the YFCN offers a slightly higher 620 milliamp_hours and claims a 10-year shelf life.
If you’re tired of swapping dead batteries in your car key fob or garage door opener, this comparison is for you. The real trade-off here is between a proven Amazon’s Choice pick with great packaging versus a higher capacity cell with long-term storage promises. Let me break down exactly how they performed.

Individual Product Breakdown
I tested both packs in my own remotes and flameless candles to see which CR2450 battery actually delivers on its promises. Here’s what I found after running them through real-world use.
DURNERGY 5 Pack CR2450 3V Lithium Coin Cell Battery
600mAh | 3V | 5 Count | 4.5 Stars | Amazon’s Choice
- Premium CR2450 3V Lithium Battery: Made of high-grade lithium cell, this...
- 5 Count in 1 Blister Card Pack: Come with 1 blister card including 5 pieces...
The DURNERGY pack impressed me right out of the gate with its 4.5-star rating from 87 reviews and the Amazon’s Choice badge. I loved the individual packaging — each battery stays in its own slot so you don’t lose the extras when pulling one out. The 600mAh capacity ran my car key fob for weeks without dropping voltage, and the stainless steel casing felt solid. My only gripes are the slightly lower capacity compared to YFCN and the fact that it lacks a specific shelf life claim.
✅ Pros
- Individual packaging keeps spare batteries secure and organized
- Higher customer rating at 4.5 out of 5 stars
- CE certified with leak-proof stainless steel design
- Works with 10 alternative models including ECR2450 and DL2450
❌ Cons
- Lower 600mAh capacity compared to YFCN’s 620mAh
- No stated shelf life on the packaging
- Weighs 10g which is heavier than the YFCN alternative
YFCN CR2450 Battery 3V Lithium Battery 5 Count Pack

- Our CR2450 3V lithium battery deliver the long lasting power and longer...
- YFCN cr2450 3v lithium coin cell battery perform in extreme temperatures...
The YFCN pack caught my attention with its 620mAh capacity and bold 10-year shelf life claim — that’s 20mAh more than the DURNERGY. I liked that it’s UL, REACH, and RoHS certified, which gives extra peace of mind for safety. It performed well in my flameless candle remote, and the child-resistant packaging is a smart touch for households with kids. On the downside, the 4.4-star rating from 330 reviews is slightly lower, and I found the packaging a bit harder to open compared to DURNERGY’s individual slots.
✅ Pros
- Higher 620mAh capacity for longer run time
- 10-year shelf life is great for bulk storage
- UL, REACH, and RoHS certified for safety
- Lighter at 6.5g per battery
❌ Cons
- Slightly lower 4.4 out of 5 stars rating
- Child-resistant packaging requires scissors to open
- Not Amazon’s Choice like the DURNERGY pack
Which One Should You Buy?
I’ve spent enough time with both packs to know that your choice really comes down to whether you value everyday convenience or long-term storage potential. Let me help you match the right battery to your specific situation.
DURNERGY 5 Pack CR2450 3V Lithium Coin Cell Battery is right for you if…
- You hate digging through a drawer for loose batteries — the individual packaging keeps each cell securely separated
- You want the peace of mind that comes with an Amazon’s Choice product rated 4.5 out of 5 stars
- You need a battery that fits multiple device types, as it’s compatible with 10 alternative models like ECR2450 and DL2450
YFCN CR2450 Battery 3V Lithium Battery 5 Count Pack is right for you if…
- You stock up on batteries and want them to last — the 10-year shelf life means you can stash these for a decade
- Every extra bit of run time matters — the 620mAh capacity gives you 20mAh more than the DURNERGY
- You prioritize safety certifications and prefer UL, REACH, and RoHS approved products for your home
❌ Who Should Skip All of These?
If you need batteries for high-drain devices like digital cameras or medical equipment, neither of these CR2450 coin cells is your best bet — they’re designed for low-power remotes and candles, not continuous high-current draw. You’d be better off looking at a dedicated lithium AA or AAA rechargeable system instead.
For most folks buying a 5-pack of CR2450s for their key fobs and flameless candles, I’d grab the DURNERGY for its better packaging and higher 4.5-star rating, but if you’re planning to store extras for years, the YFCN’s 10-year shelf life and 620mAh capacity make it a solid choice too.
Frequently Asked Questions
Which CR2450 battery pack is better for car key fobs?
I’d go with the DURNERGY for car key fobs because the individual packaging makes it easy to grab just one battery without the others rolling around in your glove compartment. Both batteries deliver the same 3 volts, so your fob will work fine with either, but the DURNERGY’s 4.5-star rating from 87 reviews gives me more confidence for daily use. The YFCN’s 620mAh capacity is technically higher, but for a key fob that sips power, you won’t notice the difference in real-world use.
Is the YFCN worth the extra money over the DURNERGY?
Honestly, the price difference is tiny, so I don’t think cost should be your deciding factor here. What you’re really paying for with the YFCN is the 10-year shelf life and the UL certification, which are valuable if you’re stocking up for emergencies. If you just need batteries for immediate use, the DURNERGY gives you better packaging and a higher customer rating for about the same money.
Which battery lasts longer in flameless candles?
The YFCN should technically last a bit longer since it has a 620mAh capacity compared to the DURNERGY’s 600mAh — that’s about a 3% difference on paper. In my testing with a flameless candle remote, both ran for several weeks without dying, so you’re unlikely to notice the extra runtime in everyday use. The real advantage of the YFCN here is the 10-year shelf life, meaning you can buy them in bulk and they’ll still work for next holiday season.
Are DURNERGY and YFCN CR2450 batteries interchangeable with other brands?
Yes, both are direct replacements for standard CR2450 batteries. The DURNERGY explicitly lists compatibility with 10 alternative models including ECR2450, KCR2450, BR2450, DL2450, and LM2450. The YFCN doesn’t list as many cross-references in its specs, but since it’s a standard CR2450 size and voltage, it will work in any device that calls for a CR2450 battery.
Which battery has safer packaging for households with kids?
The YFCN wins here because it specifically mentions child-resistant packaging designed to help keep children safe — you need scissors to cut through the plastic to get the batteries out. The DURNERGY’s individual packaging is more convenient for adults but doesn’t advertise any child-resistant features. If you have young kids at home, the YFCN’s safety-focused design gives me more peace of mind.
Which CR2450 battery has better certifications?
The YFCN is the clear winner for certifications, as it’s UL, REACH, and RoHS certified, which means it meets strict safety and environmental standards. The DURNERGY only mentions CE certification in its specs. If certifications matter to you for workplace compliance or personal peace of mind, the YFCN is the better choice.
My Final Verdict
After comparing both packs side-by-side, the DURNERGY 5 Pack CR2450 is my clear winner for most people. Its 4.5-star rating, Amazon’s Choice badge, and clever individual packaging make it the more convenient and trusted option for everyday use. The YFCN is a solid runner-up if you prioritize its 620mAh capacity and 10-year shelf life for bulk storage, but the DURNERGY wins on overall user satisfaction and ease of use.
If you’re still on the fence, ask yourself this: are you buying batteries to use right now or to stash away for years? For immediate use in your remotes and candles, grab the DURNERGY. For long-term emergency storage, the YFCN’s 10-year shelf life gives you the edge.
