I’ve been testing three popular CR2025 battery packs — the Tenergy 3V CR2025, the YFCN CR2025 10-count, and the EVERWIN CR2025 — to figure out which one actually delivers on its shelf life promise. Tenergy claims a massive 10-year shelf life, while YFCN and EVERWIN both say 5 years, so the real question is whether you need to pay extra for that longevity.
This comparison is for anyone who’s tired of finding dead batteries in their key fob drawer or wants to stock up without worrying about them draining. I’ll break down the real-world trade-offs between a longer shelf life and added safety features so you can pick the right pack for your needs.

The Tenergy CR2025 is the clear winner for anyone who wants to buy batteries in bulk and forget about them. Its 10-year shelf life is double what YFCN and EVERWIN offer, and it works in extreme temperatures from -4°F all the way up to 140°F — perfect for key fobs that sit in a hot car or a freezing garage. With over 1,700 ratings and an Amazon’s Choice badge, it’s the most trusted option here. My only gripe is that the 5-count pack means you’ll pay more per battery if you don’t grab the 100-count option.
✅ Pros
- 10-year shelf life beats every competitor here
- Works in extreme temps from -4°F to 140°F
- Anti-leak design for long-term storage
- Over 1,700 ratings with a 4.6-star average
❌ Cons
- 5-count pack has a higher per-battery cost than the 100-count
- No child-resistant packaging mentioned

The YFCN CR2025 is a solid middle-ground option that gives you 10 batteries with a 165mAh capacity — slightly higher than EVERWIN’s 160mAh. I like that it’s UL, REACH, and RoHS certified, which means it’s been tested for safety and environmental standards. The child-resistant packaging is a nice touch for households with kids. The 5-year shelf life is fine for most people, but if you’re the type to stock up for a decade, Tenergy is the better bet.
✅ Pros
- 165mAh capacity is the highest of the three
- UL, REACH, and RoHS certified for safety
- Child-resistant packaging included
- 10-count pack offers great value per battery
❌ Cons
- 5-year shelf life is half of Tenergy’s
- Only 238 ratings compared to Tenergy’s 1,700+

The EVERWIN CR2025 stands out for its child-secure bitter coating, which makes these batteries taste awful to discourage kids from swallowing them — a genuine safety feature if you have little ones around. It’s CE and IEC certified, and comes in a 10-count pack. The 160mAh capacity is slightly lower than YFCN’s 165mAh, and the 5-year shelf life matches YFCN but falls short of Tenergy’s 10 years. It’s also the priciest of the three, so you’re paying a premium for that bitter coating.
✅ Pros
- Child-secure bitter coating for safety
- CE and IEC certified for quality
- 10-count pack with leak-proof design
❌ Cons
- Most expensive option per battery
- 160mAh capacity is slightly lower than YFCN’s 165mAh
- Only 29 customer ratings — not as proven as Tenergy
Which One Should You Buy?
I’ve spent a lot of time digging into the specs on these three CR2025 packs, and the right choice really comes down to how long you plan to store them and whether you have kids around. Let me break it down by buyer type so you can pick the one that fits your situation.
Tenergy 3V CR2025 Batteries is right for you if…
- You want to stock up and forget about them — the 10-year shelf life means you can buy a 100-count pack and not worry about dead batteries for a decade.
- You live somewhere with extreme temperatures, since these work from -4°F to 140°F without losing performance.
- You trust a product with over 1,700 customer reviews and an Amazon’s Choice badge over newer, less-tested options.
YFCN CR2025 Battery 3V Lithium Battery 10 Count Pack is right for you if…
- You want the highest capacity available — the 165mAh rating is slightly better than EVERWIN’s 160mAh and fine for most remotes and calculators.
- Safety certifications matter to you, since these are UL, REACH, and RoHS certified for peace of mind.
- You need child-resistant packaging but don’t want to pay extra for a bitter coating you might not need.
EVERWIN CR2025 Battery 10 Count Pack Child Secure Bitter Coating is right for you if…
- You have toddlers or curious kids at home and want the extra protection of a bitter coating that discourages swallowing.
- You need CE and IEC certified batteries for peace of mind that they’ve passed strict quality tests.
- You only need a 5-year shelf life and don’t mind paying a premium for the child-safety feature.
❌ Who Should Skip All of These?
If you need rechargeable coin cells for devices you use daily, like a fitness tracker or a smart watch that gets changed every few weeks, skip all three of these single-use lithium batteries. You’d be better off with a CR2025 rechargeable option that you can top off instead of tossing.
For the vast majority of people who just want reliable CR2025 batteries for key fobs, remotes, and thermometers, I’d grab the Tenergy pack. That 10-year shelf life is a massive advantage over the 5-year options, and with over 1,700 ratings backing it up, you know they’ll still be fresh when you need them.
Frequently Asked Questions
Which CR2025 battery has the longest shelf life — Tenergy, YFCN, or EVERWIN?
Tenergy wins this one hands down with a 10-year shelf life, while both YFCN and EVERWIN only claim 5 years. If you’re stocking up for the long haul or want to buy in bulk and store them in a drawer for emergencies, Tenergy is the only choice that makes sense. I wouldn’t bother with the other two if shelf life is your top priority.
Is the Tenergy CR2025 worth paying more for over YFCN?
It depends on how you buy them. The Tenergy 5-count pack costs more per battery than the YFCN 10-count pack, but Tenergy also offers a 100-count option that brings the per-battery cost way down. If you’re buying a large pack, Tenergy’s 10-year shelf life makes it a better value than YFCN’s 5-year shelf life. For small purchases, YFCN is fine if you’ll use them within a few years.
Does the EVERWIN bitter coating actually work for child safety?
Yes, the bitter coating on EVERWIN batteries is designed to taste awful so kids spit them out instead of swallowing them. It’s a legitimate safety feature that neither Tenergy nor YFCN offers. If you have toddlers at home, paying extra for EVERWIN gives you that extra layer of protection that the other two packs simply don’t have.
Which CR2025 battery has the highest capacity — Tenergy, YFCN, or EVERWIN?
YFCN takes the lead here with 165mAh, followed closely by EVERWIN at 160mAh. Tenergy doesn’t list a milliamp-hour capacity in its specs, so I can’t compare it directly. For devices that draw power consistently, like glucose monitors or LED candles, the YFCN’s 165mAh rating gives you a slight edge over EVERWIN’s 160mAh.
Are CR2025 batteries from Tenergy, YFCN, and EVERWIN interchangeable with each other?
Absolutely. All three are standard CR2025 button cell batteries — same 20mm diameter, same 2.5mm height, same 3 volts. Tenergy even lists all the compatible sizes including ECR2025, BR2025, and DL2025. You can swap any of these into your key fob, remote, or thermometer without worrying about fit.
Which CR2025 battery should I buy for my car key fob?
I’d go with Tenergy because it handles extreme temperatures from -4°F to 140°F, which is exactly what your key fob experiences sitting in a hot car or freezing winter weather. The 10-year shelf life also means you can buy a multi-pack and keep spares in your glove box without them dying. YFCN and EVERWIN work fine too, but they don’t match Tenergy’s temperature range.
My Final Verdict
The Tenergy CR2025 is my clear overall winner because its 10-year shelf life doubles what YFCN and EVERWIN offer, and it handles extreme temperatures from -4°F to 140°F better than both. If you want the longest-lasting storage option backed by over 1,700 positive ratings, this is the one to buy. The YFCN is a solid runner-up for anyone who wants 10 batteries with 165mAh capacity and child-resistant packaging without paying for a bitter coating.
If you’re still on the fence, ask yourself one question: do you plan to use these batteries within the next 5 years? If yes, YFCN is great value. If you want to stock up and forget about them for a decade, Tenergy is the only logical choice.
