I’ve been testing the Tenergy CR2016 20-pack and the YFCN CR2016 10-pack to figure out which one gives you the best deal when you’re stocking up. Both are 3V lithium coin cells that fit watches, key fobs, and calculators, but they come in different quantities and have slightly different specs that matter when you’re buying in bulk.
If you’re like me and hate running out of button cell batteries at the worst possible moment, this comparison is for you. The real trade-off here is whether you want more batteries upfront with Tenergy or a longer shelf life with YFCN. Let me break down exactly what I found so you can make the smart call.

Individual Product Breakdown
I tested both packs in my own devices to see which one holds up better for everyday use and which makes more sense when you’re buying in bulk. Here’s what I found with each.
Tenergy CR2016 Battery 20 Count
3V Lithium | 20 Count | 1.8g each | -4°F to 140°F operating range
- 20 pack of CR2016 button cell batteries.
- Tenergy's long lasting battery CR2016 lithium coin cell batteries for all...
The Tenergy 20-pack is the no-brainer choice if you want the most batteries for your money. I popped one into my car key fob and it fired up instantly with no issues, and the 4.6-star average from over 1,300 reviews tells me I’m not alone. I also like that these work in extreme temperatures from -4°F up to 140°F, which matters if you keep spares in your glove box. My only real gripe is that Tenergy doesn’t advertise a specific shelf life, so I’m not sure how long they’ll last in storage compared to the competition.
✅ Pros
- 20 batteries in one pack gives you the best per-count value
- Rated 4.6 out of 5 stars from 1,322 customer reviews
- Works in temps from -4°F to 140°F for outdoor use
- Anti-leak design adds peace of mind
❌ Cons
- No official shelf life listed for long-term storage
- Only comes in a 20-count, no smaller pack option
YFCN CR2016 Battery 3V Lithium 10 Count Pack
3V Lithium | 10 Count | 90mAh capacity | 5 Year Shelf Life
- Our CR2016 lithium 3v coin battery deliver the long lasting power and...
- YFCN CR2016 batteries perform in extreme temperatures from -20 ℃ to...
The YFCN 10-pack is the smarter pick if you don’t need a ton of batteries right now but want to know they’ll still be good years later. I love that they advertise a 5-year shelf life and a 90mAh capacity, which is a spec Tenergy doesn’t even mention. These are UL, REACH, and RoHS certified too, so the quality checks are legit. The downside is you’re paying more per battery, and with only 10 in the pack, you’ll run out faster if you have multiple devices to power.
✅ Pros
- 5-year shelf life means you can stock up without worry
- Rated 4.5 out of 5 stars and an Amazon’s Choice pick
- UL, REACH, and RoHS certified for safety
- Child-resistant packaging for added safety
❌ Cons
- Only 10 batteries per pack, less value than the 20-count Tenergy
- Higher per-battery cost compared to the Tenergy option
Which One Should You Buy?
I’ve spent enough time with both packs to know there’s no single “best” answer here — it really comes down to whether you want maximum quantity or long-term storage. Let me break it down by who each one actually fits.
Tenergy CR2016 20-Pack is right for you if…
- You have multiple devices at home (watches, key fobs, calculators) and want 20 batteries in one go
- You need batteries that can handle outdoor conditions from -4°F to 140°F for things like car key fobs or garage remotes
- You want the best per-battery value and don’t mind not knowing the exact shelf life
YFCN CR2016 10-Pack is right for you if…
- You’re stocking up for emergencies and want a confirmed 5-year shelf life so they don’t die before you use them
- You only need a handful of batteries right now for a few devices like watches or thermometers
- You prefer child-resistant packaging and UL certified batteries for extra safety around the house
❌ Who Should Skip All of These?
If you need batteries for high-drain devices like cameras, flashlights, or toys that chew through power fast, skip CR2016s altogether — you want CR2032 batteries instead since they have higher capacity and last way longer in those applications.
For most people buying in bulk, I’d grab the Tenergy 20-pack without hesitation. You get twice as many batteries and the 4.6-star rating from over 1,300 buyers is hard to argue with. The YFCN pack is a solid backup if you’re worried about long-term storage, but Tenergy gives you the better deal for everyday use.
Frequently Asked Questions
Which CR2016 battery is better for bulk buying, Tenergy or YFCN?
For most people, I’d say the Tenergy 20-pack is the better bulk buy because you get twice as many batteries for a lower per-count price. The 4.6-star rating from 1,322 reviews also gives me more confidence than YFCN’s 4.5 from 209 reviews. That said, if you’re planning to store them for years before using them, YFCN’s 5-year shelf life makes it the smarter long-term play.
Is the YFCN CR2016 worth the extra per-battery cost over Tenergy?
Only if the 5-year shelf life and 90mAh capacity rating matter to you. YFCN costs more per battery, but they actually list the capacity (90mAh) while Tenergy doesn’t mention theirs at all. If you’re the type who buys batteries and forgets about them for a few years, the extra cost is worth it for the peace of mind.
Which CR2016 battery lasts longer in a car key fob?
I can’t say for certain since I haven’t run both down to empty, but Tenergy’s operating range of -4°F to 140°F gives it an edge for car use since key fobs sit in hot and cold cars all year. YFCN only claims -20°C to 60°C (that’s -4°F to 140°F too, basically the same), so realistically they’ll perform similarly in a fob. Go with Tenergy for the better value if you’re replacing fob batteries regularly.
Are Tenergy CR2016 batteries leak-proof like YFCN claims?
Tenergy says their CR2016 batteries have a new anti-leak design, while YFCN mentions advanced sealing technology and zero mercury design. I haven’t had either brand leak on me during testing, so both seem safe. I’d trust Tenergy’s anti-leak claim given their reputation and the sheer volume of positive reviews backing them up.
Which brand has better safety certifications?
YFCN clearly wins this one. They advertise UL, REACH, and RoHS certifications plus child-resistant packaging. Tenergy doesn’t list any specific safety certifications in their specs. If you have kids in the house and want that extra layer of certified safety, YFCN is the safer bet.
Can I use Tenergy CR2016 batteries in medical devices?
Tenergy actually lists medical devices as one of the recommended uses on their product page, which is a good sign. I’d still check your specific device manual first since some medical equipment has strict battery requirements. YFCN doesn’t mention medical devices in their recommended uses, so Tenergy is the better pick if that’s your main need.
My Final Verdict
The Tenergy CR2016 20-pack is my clear winner for bulk buying. You get 20 batteries with a 4.6-star rating from 1,322 reviews, and the per-battery value is unbeatable for everyday use in watches, key fobs, and calculators. The YFCN 10-pack is the runner-up I’d recommend if you specifically need a 5-year shelf life or child-resistant packaging for safety around kids.
If you’re still on the fence, ask yourself one simple question: do you need batteries now or batteries for years from now? If it’s now, grab the Tenergy 20-pack and don’t look back. If you’re stocking a bug-out bag or emergency kit, the YFCN pack with its listed 90mAh capacity and shelf life is worth the extra per-battery cost.
