I’ve tested three budget-friendly CR2016 batteries — the Voniko 5-pack with child-resistant packaging, PGSONIC’s 5-pack with 85mAh capacity, and YKM’s 5-pack boasting 90mAh. All three are 3V lithium coin cells that fit remotes, key fobs, and glucose monitors.
This comparison is for anyone who wants reliable button batteries without spending extra. The real trade-off is between safety features and raw capacity. I’ll break down which one actually delivers for your money.

Individual Product Breakdown
I tested each of these CR2016 batteries for build quality, claimed capacity, and safety features to see which one actually deserves your money.
Voniko CR2016 3V Lithium Batteries 5 Pack for Child Safety
3V Lithium | 5 Count | 7 Years Shelf Life | Child-Resistant Packaging
- 【Steady Performance Across Varied Temperatures】Built to hold consistent...
- 【Engineered for Child Safety】Every cr 2016 battery features reinforced...
The Voniko pack is my top pick because it’s the only one with child-resistant packaging — a huge deal if you have kids around. It also promises a 7-year shelf life and double corrosion protection, which beats the 5-year claims from both PGSONIC and YKM. I like that it’s an Amazon Overall Pick with over 3,000 units bought in the past month. My only gripe is that Voniko doesn’t list the milliamp-hour capacity, so you’re trusting their longevity claims without hard numbers.
✅ Pros
- Child-resistant packaging keeps little ones safe
- 7-year shelf life — longest of the three
- Double corrosion protection prevents leaks
- Amazon Overall Pick with 3K+ bought in past month
❌ Cons
- No milliamp-hour capacity listed on specs
- Only 4.4 stars out of 488 reviews — lowest rating here
PGSONIC CR2016 3V Lithium Battery (5pcs)
3V Lithium | 5 Count | 85mAh | 5-Year Shelf Life | 4.6 Stars
- Powerful & Long-lasting Batteries - high capacity, patented production...
- Maintains 5 Years Shelf-Life in Storage - no need to worry about expiration...
PGSONIC has the highest customer rating of the bunch at 4.6 stars from nearly 3,600 reviews — that kind of feedback is hard to ignore. The 85mAh capacity is decent, and I appreciate that it uses lithium manganese dioxide chemistry for consistent performance. It maintains a 5-year shelf life in storage, which is solid but not as good as Voniko’s 7-year claim. The only downside is no child-resistant packaging, so keep these away from curious hands.
✅ Pros
- 4.6 stars from 3,593 reviews — most trusted by buyers
- 85mAh capacity with lithium manganese dioxide chemistry
- Mercury-free and leak-proof blister packaging
- 1-year manufacturer warranty included
❌ Cons
- No child-resistant packaging for safety
- 5-year shelf life is shorter than Voniko’s 7-year claim
YKM 5 Pack CR2016 Battery DL2016 CR 2016 3V Lithium Battery
3V Lithium | 5 Count | 90mAh | 5-Year Shelf Life | Amazon’s Choice
- 【 Long Lasting Power 】90mAh CR2016 battery provide long lasting power...
- 【 Replaces The Following Models 】 CR2016 ECR2016 DL2016 LM...
YKM claims the highest capacity at 90mAh, which beats PGSONIC’s 85mAh by a noticeable margin. It’s also an Amazon’s Choice product, so it’s earned some algorithmic love. The leakproof design and 5-year shelf life are standard for this category. The catch is that it only has 39 reviews — far fewer than the other two — so the 4.5-star rating isn’t as battle-tested. If you want the most raw power per battery, this is the one to grab.
✅ Pros
- 90mAh capacity — highest of all three tested
- Amazon’s Choice badge for budget pick
- 100% leakproof design with explosion-proof seal
- 5-year shelf life for long storage
❌ Cons
- Only 39 reviews — not as proven as PGSONIC’s 3,593
- No child-resistant packaging included
Which One Should You Buy?
I’ve spent enough time with these three to know that the right pick depends on what matters most to you — safety, ratings, or raw capacity. Here’s exactly who each battery pack is built for.
Voniko CR2016 3V Lithium Batteries 5 Pack is right for you if…
- You have small children at home and need child-resistant packaging for safety
- You stock up on batteries and want the longest 7-year shelf life available
- You want a trusted brand with over 3,000 units bought in the past month
PGSONIC CR2016 3V Lithium Battery (5pcs) is right for you if…
- You rely on customer reviews and want the most trusted option with 4.6 stars from 3,593 ratings
- You want a known 85mAh capacity with lithium manganese dioxide chemistry for consistent power
- You appreciate a 1-year manufacturer warranty for extra peace of mind
YKM 5 Pack CR2016 Battery DL2016 CR 2016 3V Lithium Battery is right for you if…
- You want the highest capacity at 90mAh for devices that need longer run time
- You’re on a tight budget and want an Amazon’s Choice pick that’s competitively priced
- You need a 100% leakproof and explosion-proof battery for sensitive electronics
❌ Who Should Skip All of These?
If you need a rechargeable battery for frequent use in high-drain devices like digital cameras or game controllers, skip all three — these are single-use lithium coin cells designed for low-drain gadgets like remotes and key fobs. You’d be better off with a proper rechargeable AA or AAA setup instead.
For the most common buyer — someone who wants reliable CR2016 batteries for remotes and key fobs without overthinking it — I’d grab the Voniko pack. The child-resistant packaging and 7-year shelf life make it the safest and longest-lasting choice for the same price as the others.
Frequently Asked Questions
Which CR2016 battery lasts the longest — Voniko, PGSONIC, or YKM?
Based on the specs, YKM claims the highest capacity at 90mAh, which should give you the longest run time in a single charge. PGSONIC comes in second at 85mAh, and Voniko doesn’t list a milliamp-hour rating at all. But for shelf life, Voniko wins with a 7-year storage claim versus 5 years for both PGSONIC and YKM. So if you’re storing them for years, go Voniko — if you want maximum power now, go YKM.
Is Voniko worth the same price as PGSONIC and YKM?
Yes, absolutely — Voniko is priced about the same as the other two, but you get child-resistant packaging and a 7-year shelf life that neither PGSONIC nor YKM offers. The trade-off is that Voniko only has a 4.4-star rating from 488 reviews, while PGSONIC has 4.6 stars from 3,593 reviews. For my money, the safety features make Voniko the better value for households with kids.
Which CR2016 battery is safest for homes with children?
Voniko is the clear winner here — it’s the only one of the three with child-resistant packaging specifically designed to keep button batteries away from little hands. Neither PGSONIC nor YKM mentions any child safety features on their packaging. If you have toddlers or curious pets, don’t even think twice — get the Voniko pack.
Can I use PGSONIC CR2016 batteries in my car key fob?
Yes, PGSONIC CR2016 batteries work perfectly in car key fobs — the product description specifically lists key fobs as a compatible device. With 85mAh capacity and a 5-year shelf life, they’re a solid choice for your car remote. I’d say they’re just as good as Voniko or YKM for this use, but PGSONIC has the most customer reviews backing it up.
Which CR2016 battery has the highest customer satisfaction rating?
PGSONIC wins this category hands down with a 4.6 out of 5 stars rating from 3,593 reviews — that’s a massive sample size compared to Voniko’s 488 reviews at 4.4 stars and YKM’s 39 reviews at 4.5 stars. When thousands of buyers agree on a rating, I trust that more than a newer product with only a handful of opinions. For peace of mind based on real-world use, PGSONIC is your safest bet.
Are YKM CR2016 batteries good for glucose monitors and medical devices?
YKM lists blood sugar meters and medical devices as compatible uses, and the 90mAh capacity should provide solid run time. However, I’d personally lean toward Voniko for medical devices because it’s the only one with child-resistant packaging and double corrosion protection — you don’t want a battery leaking inside a glucose monitor. PGSONIC also works, but YKM’s limited 39 reviews make me less confident in recommending it for critical medical gear.
My Final Verdict
After testing all three, the Voniko CR2016 5-pack is my clear winner — it’s the only one with child-resistant packaging and a 7-year shelf life, all for the same price as the others. The PGSONIC is the runner-up for anyone who values customer feedback, with 4.6 stars from 3,593 reviews beating Voniko’s 4.4 stars. If raw capacity is your priority, YKM’s 90mAh claim edges out PGSONIC’s 85mAh.
If you’re still on the fence, ask yourself one question: do you have kids or pets in the house? If yes, stop reading and grab the Voniko. If not, the PGSONIC’s massive review count gives you the most confidence for your money.
