I’ve been there ā your key fob dies at the worst moment, or the remote for your LED holiday lights goes silent. So I grabbed this YFCN CR2016 Battery 3V Lithium Battery 10 Count Pack to see if it lives up to the 5-year shelf life and 90mAh capacity claim.
These coin cells are ideal for anyone juggling multiple devices like watches, calculators, or door chimes. They’re certified UL, REACH, and RoHS, and the child-resistant packaging is a thoughtful touch. My only gripe? You’ll need scissors to open that packaging ā it’s secure but not tear-friendly.

What Stands Out ā Key Features
- Long Shelf Life: YFCN claims a 5-year shelf life, and based on the packaging and build quality, I believe these will stay fresh in my drawer for years.
- Full 3V Charge: Each battery came with a full 3 volts when I tested them with a multimeter, so they’re ready to use right out of the pack.
- Safety Certifications: I appreciate that these are UL, REACH, and RoHS certified ā it gives me confidence they’re safe to use around the house.
- Leak-Proof Design: The advanced sealing technology and zero mercury design mean I don’t have to worry about corrosion in my devices.
- Child-Resistant Packaging: The packaging is tough to open without scissors, which is exactly what you want if kids are around. It’s a minor hassle for peace of mind.
- Extreme Temperature Performance: They work from -20Ā°C to 60Ā°C, so I can use them in outdoor LED lights or a cold garage without issues.
- 10-Pack Convenience: I got 10 batteries in a single pack, and the protective packaging lets me remove one at a time without losing the rest.

Pros & Cons ā The Honest Take
ā What I Like
- The 5-year shelf life means I can stash a pack in my drawer and forget about it until I need a replacement.
- Each battery delivered a full 3 volts right out of the package, with a 90mAh capacity that kept my key fob running for weeks.
- I love the UL, REACH, and RoHS certifications ā it’s rare to see this level of safety testing on coin cells.
- The leak-proof design with zero mercury gave me peace of mind when I put one in my expensive watch.
- They work reliably in extreme temperatures from -20Ā°C to 60Ā°C, which is perfect for my outdoor LED Christmas lights.
ā What Could Be Better
- The child-resistant packaging is so tough that I needed scissors every time ā no way to tear it open by hand.
- At only 1.7g each, the batteries are tiny and easy to lose if you drop one on a carpet.
Overall, the pros far outweigh the cons for me ā the safety certifications and long shelf life make these a solid choice for everyday devices, even if the packaging is a pain to open.
āļø How Does It Compare?
I picked the XUNIUZERO CR2016 and YKM 5 Pack CR2016 as the closest alternatives because they’re both 3V lithium coin cells in the same size, but each takes a slightly different approach to packaging and value. Let me break down how they stack up against the YFCN 10-pack.

- Child-Resistant Packaging ā To help ensure the safety of your children...
šµ Alternative 1: XUNIUZERO CR2016
Best for: Someone who wants a simple, no-fuss CR2016 without the child-resistant packaging hassle.
Key specs: 3V lithium | 90mAh capacity | 20mm x 1.6mm | single-use
Where it beats the main product: The packaging is easier to open by hand since it doesn’t use the same heavy-duty child-resistant design as YFCN.
Where it falls short: I couldn’t confirm any safety certifications like UL, REACH, or RoHS, which YFCN explicitly lists ā that matters to me for peace of mind.

āŖ Alternative 2: YKM 5 Pack CR2016
Best for: Someone who only needs a few batteries and doesn’t want to store a full 10-pack.
Key specs: 3V lithium | 90mAh capacity | 5-pack | single-use
Where it beats the main product: The smaller 5-pack is more economical if you just need a quick replacement for one device and don’t want extras sitting around.
Where it falls short: At only 5 batteries, you’re getting half the quantity of the YFCN 10-pack, and I couldn’t verify any shelf life claims or temperature ratings.
If you’re stocking up for multiple devices and want the peace of mind that comes with UL, REACH, and RoHS certifications plus a 5-year shelf life, I’d stick with the YFCN 10-pack. The XUNIUZERO is a decent backup if you hate struggling with child-resistant packaging, and the YKM 5-pack works fine for a single quick replacement ā but neither offers the same safety credentials or long-term storage confidence as the YFCN.
How It Actually Performs
Voltage Output ā Consistent 3V Right Out of the Box
I tested every single battery from the 10-pack with a multimeter before using them, and each one read a steady 3 volts. That’s exactly what YFCN promises, and it’s reassuring because some cheap coin cells I’ve tried in the past arrived at 2.8V or lower. The 90mAh capacity also held up in my key fob ā after three weeks of daily use, the remote still felt as responsive as day one. No voltage drop-off to report yet.
Real-World Device Compatibility
I swapped one into my car key fob, another into a small digital scale, and a third into a basic LED tea light remote. Every device fired up immediately without any hesitation. The 20mm diameter and 1.6mm height fit perfectly into each compartment ā no wobbling or loose connections. YFCN lists compatibility with watches, calculators, thermometers, and door chimes, and based on my testing, I’d trust these in any CR2016-powered gadget around the house.
Temperature Tolerance and Storage
I left one battery in my car’s glovebox for a week where temps fluctuated from near freezing at night to about 30Ā°C during the day. After that, the battery still read 3V on the multimeter and powered my remote without issues. YFCN claims these work from -20Ā°C to 60Ā°C, and while I didn’t test the extremes, the moderate range I tried didn’t phase them. The 5-year shelf life claim seems believable given the tight packaging and sealed design.
Packaging and Handling Experience
The child-resistant packaging is genuinely frustrating to open ā I needed scissors every single time, and even then, cutting through the thick plastic took some effort. On the plus side, the individual compartments keep each battery isolated, so I can grab one without worrying about the others rolling away. At just 1.7g per battery and a total pack weight of 1.28 ounces, the whole thing fits easily in a drawer or glovebox. Just keep those scissors handy.
Who Is This Battery Pack Best For?
After testing the YFCN CR2016 Battery 3V Lithium Battery 10 Count Pack across several devices, I’ve got a clear picture of who will love it and who might want to skip it. Here’s my honest breakdown.
ā This Is a Great Fit If You…
- Want a bulk supply of 10 batteries to keep in a drawer for emergencies ā the 5-year shelf life means you won’t waste them.
- Need certified safety with UL, REACH, and RoHS marks, especially if you’re putting these in devices kids or elderly relatives use.
- Own multiple CR2016-powered gadgets like key fobs, watches, calculators, and LED remotes and want a single pack to cover them all.
- Store devices in areas with temperature swings, since these work from -20Ā°C to 60Ā°C without losing their 3V charge.
ā You Might Want to Look Elsewhere If…
- You have arthritis or limited hand strength ā the child-resistant packaging requires scissors and some effort to open.
- You only need one or two batteries right now ā a smaller 5-pack might be more practical than storing 10.
- You prefer packaging you can tear open by hand ā this isn’t that kind of product, and that’s by design for safety.
If you’re someone who likes being prepared and values third-party safety certifications, this 10-pack is my top recommendation for keeping your key fobs and remotes running without hassle.

Common Issues & Fixes
After spending time with these CR2016 batteries, I ran into a few predictable hiccups. Here’s what I learned and how to work around them.
Battery Doesn’t Fit Snugly in the Device
The problem: You slide the new battery into your key fob or watch, but it feels loose or won’t stay in place.
My fix: Check that you’re using the correct side up ā the positive (+) side should face the contact spring. Also, make sure the device actually takes CR2016 (20mm x 1.6mm) and not a CR2032, which is thicker at 3.2mm. If it’s the right size but still loose, the metal contact tab inside might be bent; gently pry it up with a small flathead screwdriver.
Child-Resistant Packaging Is a Pain to Open
The problem: You try to tear the plastic pack open by hand and end up wrestling with it for five minutes.
My fix: Don’t bother trying to tear it ā grab a pair of scissors and cut along the edge of the individual battery compartment. I found that cutting close to the battery itself gives you the cleanest opening. Keep the remaining batteries in the uncut compartments so they stay protected.
Battery Doesn’t Work Right After Installation
The problem: You put in a fresh battery, but the device still won’t power on or acts glitchy.
My fix: First, wipe the battery contacts with a dry cloth ā sometimes a thin film from manufacturing can block the connection. If that doesn’t work, test the battery with a multimeter to confirm it’s delivering the full 3 volts. I tested all 10 in my pack and they read perfectly, but a dud is possible with any brand. If you get one, Amazon’s 30-day return policy should cover it.
Batteries Arrive With Low Voltage
The problem: You test a battery from the pack and it reads under 3V, making you question the 5-year shelf life claim.
My fix: This didn’t happen to me ā all mine read a solid 3V ā but if it does, double-check your multimeter settings and test a known good battery for comparison. If it’s genuinely low, contact YFCN through Amazon for a replacement. The shelf life only applies if you store them in a cool, dry place as instructed, so keep the pack away from heat and humidity.
Warranty & Support
Amazon offers a voluntary 30-day return guarantee on this product, so you can send it back if something’s wrong. For warranty details beyond that, you’ll need to check the product page on Amazon ā I didn’t find a specific YFCN warranty period listed, but the return policy gives you a solid safety net.

Frequently Asked Questions
Are these batteries compatible with my key fob or watch?
If your device uses a CR2016 battery, then yes ā these are exactly that size at 20mm diameter and 1.6mm height. I tested mine in a car key fob, a digital scale, and a remote for LED lights, and they all worked perfectly. Just double-check your device’s manual to confirm it takes CR2016 and not the thicker CR2032, since those won’t fit.
How long do these batteries actually last once installed?
That depends entirely on the device. In my key fob, the battery was still going strong after three weeks of daily use. For low-drain gadgets like a thermometer or a watch, you could easily get a year or more. The 90mAh capacity is standard for CR2016 cells, so expect typical runtimes for this battery size ā they won’t outlast a higher-capacity CR2032, but they’re right where they should be.
Is the child-resistant packaging really that hard to open?
Honestly, yes ā you’ll need scissors every time. I tried tearing it by hand and got nowhere. The plastic is thick and tough by design, which is great for safety but annoying for quick access. My advice is to cut along the edge of the individual compartment you need and leave the rest sealed. It’s a trade-off I can live with for the added child safety.
Can I store these in my car or garage?
Yes, within reason. YFCN rates these for temperatures from -20Ā°C to 60Ā°C, so a hot car in summer or a cold garage in winter shouldn’t be an issue. I left one in my glovebox for a week with temperature swings and it still read 3V on my multimeter. Just avoid direct sunlight or extreme heat above 60Ā°C, and they’ll hold their charge for the full 5-year shelf life.
What safety certifications do these batteries have?
YFCN lists UL, REACH, and RoHS certifications, which is more than I usually see on coin cell batteries at this level. That means they’ve been tested for safety standards, restricted substance compliance, and EU chemical regulations. I found them a reassuring choice for devices around kids, especially since they’re also zero mercury and leak-proof.
What if I get a defective battery ā can I return them?
Amazon offers a voluntary 30-day return guarantee on this product, so you can send the whole pack back if something’s wrong. I tested all 10 batteries in my pack and they all delivered the full 3 volts, so defects seem rare based on the 4.5-star rating from 209 reviews. If you do get a dud, just start a return on Amazon within 30 days of delivery.
My Final Verdict
After testing the YFCN CR2016 10-pack across multiple devices, I’m genuinely impressed with the consistent 3V output, the 90mAh capacity that kept my key fob running for weeks, and the peace of mind that comes with UL, REACH, and RoHS certifications. I’d recommend this pack to anyone who wants a reliable stockpile of batteries for watches, remotes, and key fobs, especially if you value safety certifications. If you only need one battery right now or struggle with tough packaging, you might prefer a smaller, easier-to-open alternative.
The child-resistant packaging is the biggest annoyance, but I understand why it’s there ā and a pair of scissors solves the problem in seconds. For the 5-year shelf life, the temperature tolerance from -20Ā°C to 60Ā°C, and the leak-proof design, I’d buy these again without hesitation.
