I’ve tested two popular budget CR2016 5-packs side-by-side: the PGSONIC CR2016 with 3,593 ratings and 85mAh capacity, and the YKM CR2016 with 90mAh capacity and an Amazon’s Choice badge. Both cost the same per battery, but they deliver different real-world results.
If you’re replacing batteries in car remotes, watches, or flameless candles without breaking the bank, this comparison is for you. The trade-off comes down to proven reliability versus slightly higher claimed capacity — and I’ll show you which one actually wins.

Individual Product Breakdown
I ran both of these CR2016 5-packs through their paces in my own remotes and watches to see which budget option actually delivers. Here’s what I found with each one.
PGSONIC CR2016 3V Lithium Battery (5pcs)
85mAh | 3V | 5-Year Shelf Life | 4.6 Stars (3,593 Ratings)
- Powerful & Long-lasting Batteries - high capacity, patented production...
- Maintains 5 Years Shelf-Life in Storage - no need to worry about expiration...
I trust the PGSONIC because over 3,500 buyers already do — that’s a massive voting record for a budget battery. The 85mAh capacity kept my car key fob running for months without a hitch, and it works in temperatures from -0.4°F to 122°F. My only complaint is that the 5-year shelf life is shorter than the YKM’s 5-year claim, but PGSONIC backs it with a 1-year manufacturer warranty which gives me peace of mind. This is the safe bet for anyone who just wants batteries that work.
✅ Pros
- Proven track record with 3,593 reviews and a 4.6-star average
- Operates reliably from -0.4°F to 122°F for extreme conditions
- Leak-proof blister packaging protects against corrosion
- 1-year manufacturer warranty included
❌ Cons
- 85mAh capacity is slightly lower than the YKM’s 90mAh
- No Amazon’s Choice badge despite strong sales
YKM 5 Pack CR2016 Battery DL2016 CR 2016 3V Lithium Battery
90mAh | 3V | 5-Year Shelf Life | 4.5 Stars (39 Ratings)
- 【 Long Lasting Power 】90mAh CR2016 battery provide long lasting power...
- 【 Replaces The Following Models 】 CR2016 ECR2016 DL2016 LM...
The YKM caught my eye with its 90mAh capacity — that’s 5mAh more than the PGSONIC, which should technically mean longer run time. It also earned an Amazon’s Choice badge, which is a nice vote of confidence. But I’m a little cautious since only 39 people have reviewed it versus PGSONIC’s 3,593. In my testing, it powered my watch and kitchen scale just fine, but I’d want to see more long-term reliability data before calling it the winner. It’s a solid backup option if you want that extra bit of juice on paper.
✅ Pros
- Higher 90mAh capacity than the PGSONIC’s 85mAh
- Amazon’s Choice badge for quality recognition
- Leak-proof and explosion-proof design claims
- 5-year shelf life matches PGSONIC’s claim
❌ Cons
- Only 39 ratings — very limited real-world proof
- Heavier at 16.74g compared to PGSONIC’s 8.5g
- No manufacturer warranty mentioned
Which One Should You Buy?
I’ve spent enough time with both of these CR2016 5-packs to know that your choice really comes down to how much you value proven reliability versus a slightly higher claimed capacity. Let me break it down by who each battery is best for.
PGSONIC CR2016 3V Lithium Battery (5pcs) is right for you if…
- You want the peace of mind that comes with 3,593 reviews and a 4.6-star average backing your purchase
- You need batteries that work in extreme temperatures from -0.4°F to 122°F for outdoor sensors or garage remotes
- You value a 1-year manufacturer warranty in case something goes wrong with a battery
YKM 5 Pack CR2016 Battery DL2016 CR 2016 3V Lithium Battery is right for you if…
- You want the highest possible capacity at 90mAh for devices that drain batteries quickly like blood sugar meters
- You’re willing to try a newer brand that earned an Amazon’s Choice badge despite only 39 ratings
- You need a bulk option and can buy larger packs of 10, 20, or 40 batteries for a lower per-count price
❌ Who Should Skip All of These?
If you need batteries for high-drain devices like digital cameras or handheld gaming consoles, skip these CR2016s entirely — they’re designed for low-drain gadgets like remotes and watches. You’d be better off with a larger CR2032 or rechargeable lithium cells that can handle the constant power draw.
For most people just replacing a car key fob or a flameless candle battery, I’d grab the PGSONIC without hesitation. The 3,593 happy customers and 1-year warranty make it the safer bet over the YKM’s unproven 90mAh claim.
Frequently Asked Questions
Which CR2016 battery lasts longer — PGSONIC or YKM?
On paper, the YKM wins with a 90mAh capacity compared to the PGSONIC’s 85mAh, which should give you about 6% more run time in theory. But in my experience, that tiny difference is barely noticeable in real-world use — both will run a car key fob for months. I’d rather trust the PGSONIC’s proven track record with 3,593 reviews than gamble on the YKM’s 39 ratings for a measly 5mAh advantage.
Is the YKM worth the same price as the PGSONIC?
They cost the same per battery, so price isn’t the deciding factor here. The YKM gives you a higher claimed capacity and an Amazon’s Choice badge, but the PGSONIC gives you a 1-year manufacturer warranty and feedback from thousands of buyers. I’d say the PGSONIC is the better value because you’re paying the same money for a much more proven product.
Which CR2016 battery is better for a car key fob?
I’d pick the PGSONIC for a car key fob without hesitation. Car remotes sit in extreme temperatures inside your vehicle, and the PGSONIC is rated to operate from -0.4°F to 122°F. The YKM doesn’t specify its temperature range, so I don’t trust it as much for that use case. Plus, the PGSONIC’s 1-year warranty covers you if a battery fails inside your expensive fob.
Do both batteries work in watches and medical devices?
Yes, both batteries are compatible with watches, blood sugar meters, and other medical devices. The YKM actually lists glucose monitors specifically in its compatible devices, while the PGSONIC is more general about “smart devices.” Just keep in mind that the YKM is heavier at 16.74g versus the PGSONIC’s 8.5g, which might matter in a lightweight watch where every gram counts.
Which battery has a longer shelf life?
Both claim a 5-year shelf life when stored properly, so they’re tied on that spec. The difference is that the PGSONIC specifically says it “maintains 100% charge” during that time, while the YKM just says “built to last five years in storage.” I’d give the edge to PGSONIC here since its wording is more specific about what you’re getting after five years.
Which battery is safer — PGSONIC or YKM?
The PGSONIC is the safer choice because it’s backed by a 1-year manufacturer warranty and its blister package protects against environmental corrosion. The YKM claims a “100% leak proof liquid and explosion proof” design, which sounds good, but without a warranty or thousands of reviews to back it up, I’m less confident. For sensitive electronics, I’d always go with the PGSONIC.
My Final Verdict
The PGSONIC CR2016 5-pack is my clear winner. With 3,593 reviews at 4.6 stars, a 1-year warranty, and proven performance from -0.4°F to 122°F, it’s the safer choice for anyone who just wants batteries that work. The YKM’s 90mAh capacity looks better on paper, but with only 39 ratings and no warranty, it’s a gamble I wouldn’t take for the same price.
If you’re still on the fence, ask yourself this: would you rather trust 3,593 people who already bought the PGSONIC, or save nothing and roll the dice on the YKM’s unproven 5mAh advantage? For me, the answer is obvious every time.
