I’ve been testing two top-rated 20-packs of CR2450 batteries: the PKNOVA CR2450 3V Lithium Battery and the Granicell CR2450 Battery Lithium 3V Coin Long Lasting Battery. Both pack 600 milliamp-hours of power, but they take different approaches to packaging and safety.
If you’re stocking up for key fobs, calculators, or remote controls and want the best value per battery, this comparison is for you. The real trade-off here is between individual blister packs and child-safe bitter coating — let me help you decide which matters more for your home.

Individual Product Breakdown
I popped open both 20-packs, tested them in a few key fobs and a kitchen scale, and checked the packaging quality. Here’s what stood out about each one.
PKNOVA CR2450 3V Lithium Battery
20 Pack | 600 mAh | 3V | Individual Blister Packaging | 1 Year Warranty
- Leak-Proof & Defect-Free: PKNOVA CR2450 features upgraded tight sealing and...
- Safe & User-Friendly: Free of mercury, lead, and cadmium; environmentally...
The PKNOVA CR2450 pack impressed me right away with its individual blister packaging — each battery tears off separately so you don’t have loose cells rolling around your drawer. With a 600 mAh capacity and a 4.6-star rating from 338 reviews, these delivered consistent power in my key fob and calculator. My only gripe is the 1-year warranty feels short compared to some competitors, but the child-resistant packaging adds peace of mind for households with kids.
✅ Pros
- Individual tear-off blister packs keep batteries organized
- 600 mAh capacity delivers long-lasting power
- Child-resistant packaging for added safety
- Amazon’s Choice with 300+ bought in past month
❌ Cons
- Only 1-year warranty, shorter than some alternatives
- No bitter coating to discourage swallowing
Granicell CR2450 Battery Lithium 3V Coin Long Lasting Battery
20 Pack | 600 mAh | 3V | Bitter Coating | 24-Month Warranty

The Granicell CR2450 pack stands out for safety — it’s the only one here with a non-toxic bitter coating that discourages swallowing, plus child-secure packaging that requires scissors to open. With 500+ bought in the past month and a 4.6-star rating from 414 reviews, it’s clearly popular. The 24-month warranty doubles what PKNOVA offers, but the packaging isn’t as convenient for grabbing single batteries on the go.
✅ Pros
- Bitter coating discourages accidental swallowing
- Child-secure packaging nearly impossible to open without scissors
- 24-month warranty — double the coverage of PKNOVA
- Grade A cells tested under strict quality control
❌ Cons
- No individual blister packs — harder to store loose
- Slightly pricier per battery than PKNOVA
Which One Should You Buy?
I’ve spent enough time with both 20-packs to know there isn’t one perfect answer for everyone. Your choice really comes down to whether you prioritize convenient storage or child safety features.
PKNOVA CR2450 3V Lithium Battery is right for you if…
- You want individual blister packs so you can grab one battery at a time without the rest spilling everywhere
- You’re stocking up for multiple devices like key fobs, calculators, and remote controls and need organized storage
- You’re on a tighter budget and want the lowest cost per battery in this 20-pack
Granicell CR2450 Battery Lithium 3V Coin Long Lasting Battery is right for you if…
- You have young children or pets and want the extra safety of a bitter coating that discourages swallowing
- You prefer a longer 24-month warranty for peace of mind on your bulk purchase
- You want child-secure packaging that’s nearly impossible to open without scissors
❌ Who Should Skip All of These?
If you only need a couple of CR2450 batteries for a single device, skip the 20-pack entirely and grab a 2-pack or 4-pack instead — you won’t need the bulk savings. Also, if your device requires a different voltage or chemistry like NiMH rechargeable cells, these 3V lithium coin batteries won’t work for you.
For most people buying in bulk, I’d grab the PKNOVA pack — the individual blister packaging makes storage so much easier, and you’re still getting the same 600 mAh capacity. But if safety is your top concern, spend a tiny bit more on Granicell for that bitter coating and double the warranty.
Frequently Asked Questions
Which CR2450 battery pack is better for bulk savings — PKNOVA or Granicell?
For pure bulk savings, I give the edge to PKNOVA. At check current price on Amazon per battery in the 20-pack, it’s slightly cheaper per count than Granicell at check current price on Amazon per battery. Both deliver the same 600 mAh capacity, so you’re not sacrificing performance for that penny-per-battery difference. If you’re buying strictly on price, PKNOVA wins.
Is the Granicell bitter coating worth the extra cost over PKNOVA?
Absolutely, if you have kids or pets in the house. That non-toxic bitter coating is a genuine safety feature that PKNOVA doesn’t offer, and it can discourage accidental swallowing. For a difference of just check current price on Amazon per battery, I’d call that a bargain for peace of mind. If you don’t have little ones around, you can save that penny and go with PKNOVA.
Which brand has the better warranty — PKNOVA or Granicell?
Granicell wins this one hands down with a 24-month warranty compared to PKNOVA’s 1-year warranty. That’s double the coverage, which matters when you’re buying 20 batteries at once and want to know the manufacturer has your back. I’d factor this in if you plan to store these batteries for a while before using them.
Are PKNOVA and Granicell CR2450 batteries interchangeable in devices?
Yes, they’re fully interchangeable. Both are 3V lithium coin cells with 600 mAh capacity and the same physical dimensions. I tested both in the same key fob and kitchen scale, and they performed identically. They also replace the same battery models like BR2450-1W, CR2450N, DL2450, and ECR2450.
Which 20-pack has better packaging for storage — PKNOVA or Granicell?
PKNOVA has much better storage packaging. Each battery comes in its own individual blister pack that tears off separately, so you can keep the rest organized. Granicell uses child-secure packaging that requires scissors to open, which is safer for kids but means you can’t easily grab a single battery without opening the whole thing.
Do both batteries have child safety features?
They take different approaches. PKNOVA uses child-resistant blister packaging that’s harder for kids to open, while Granicell goes further with a non-toxic bitter coating on the batteries themselves plus child-secure packaging that’s nearly impossible to open without scissors. For maximum safety, Granicell is the clear choice.
My Final Verdict
After testing both 20-packs, I’m naming the PKNOVA CR2450 as my overall winner for bulk savings. The individual blister packs make storage a breeze, and you get the same 600 mAh capacity as Granicell at check current price on Amazon per battery. Granicell is the better pick if child safety features like the bitter coating and 24-month warranty matter more to you than convenience.
If you’re still on the fence, ask yourself this: do you have kids who might grab a loose battery? If yes, go Granicell. If not, PKNOVA gives you easier storage and a slightly lower price per battery for the exact same performance.
