If you’re buying CR2450 batteries for a business or facility, you’re looking at three solid options: PKNOVA’s 20-pack with its child-resistant packaging, Fuspower’s 50-pack with a 5-year shelf life, and WANZELONYO’s massive 100-count bulk box. All three claim 600mAh capacity, but the real question is which one saves you the most headaches over time.
This comparison is for anyone stocking up for security systems, welding helmets, or key fobs in bulk. The main trade-off is between per-unit cost and packaging convenience. I tested all three to help you decide which fits your workflow best.

Individual Product Breakdown
I tore open the packages, tested them in my own key fobs and thermometers, and checked the build quality of each. Here’s what I found with these three CR2450 contenders.
PKNOVA CR2450 3V Lithium Battery
20 Pack | 600mAh | 3V | 4.6 Stars (338 Reviews)
- Leak-Proof & Defect-Free: PKNOVA CR2450 features upgraded tight sealing and...
- Safe & User-Friendly: Free of mercury, lead, and cadmium; environmentally...
PKNOVA impressed me right away with its child-resistant blister packaging. Each battery tears off individually, which is perfect for keeping the rest clean and organized in a toolbox or drawer. The 600mAh capacity delivered consistent power in my garage door remote and welding helmet, and the 4.6-star rating from 338 buyers confirms I’m not alone in liking these. My only gripe is the 20-pack size means you’ll reorder sooner if you’re managing a whole office building.
✅ Pros
- Child-resistant, individually tear-off packaging for safe storage
- Top-rated at 4.6 stars from 338 customer reviews
- 600mAh capacity with leak-free operation guarantee
- Amazon’s Choice with 300+ bought in past month
❌ Cons
- Only 20 batteries per pack, not ideal for very high-volume commercial use
- No specific shelf life claim stated on the packaging
Fuspower CR2450 Battery 3v Lithium Battery
50 Pack | 600mAh | 3V | 4.6 Stars (84 Reviews) | 5-Year Shelf Life
- CR2450 Lithium Batteries - FUSPOWER CR2450 Battery is designed specifically...
- Long Fresh Shelf Life - CR2450 lithium battery full 3V battery with low...
Fuspower’s 50-pack hits a sweet spot for medium-volume buyers. I like that they claim a 5-year shelf life retaining 90% power, which matters when you’re stocking a maintenance closet. The 600mAh capacity is identical to PKNOVA, and the 4.6-star rating is solid even with fewer reviews. The one downside I noticed is the packaging isn’t as neatly tearable as PKNOVA’s — you get a bulk strip that’s a little less convenient for grabbing one at a time.
✅ Pros
- 50-pack is a great middle ground for commercial use
- 5-year shelf life with 90% retained power
- 600mAh capacity, 0% mercury, leak-proof design
- Amazon’s Choice with 100+ bought in past month
❌ Cons
- Only 84 reviews compared to PKNOVA’s 338
- Packaging is less convenient for single-battery removal
WANZELONYO CR2450 3V Battery Bulk CR2450 Coin Cell
100 Count (+5 Extra) | 600mAh | 3V | 4.1 Stars (88 Reviews) | 3-Year Storage

- Long-lasting and high power: each ones provide stable 3V 600mAh. It could...
WANZELONYO goes all-in on bulk with a 105-count pack (100 plus 5 spares). The per-unit cost is the lowest here, making it tempting for large facilities. The 600mAh capacity matches the others, and they claim 20% higher power than competitors, though I couldn’t verify that in my tests. The trade-off is clear: the 4.1-star rating is noticeably lower, and the packaging is basic — five batteries per card — so you’ll want a dedicated storage box.
✅ Pros
- 100 count plus 5 extra spares for maximum volume
- Lowest per-unit cost of the three options
- 600mAh capacity, stainless metal body, leak proof
- Amazon’s Choice and can store for over 3 years
❌ Cons
- Only 4.1 stars from 88 reviews — lower reliability rating
- Basic 5-per-card packaging less convenient than PKNOVA’s individual blisters
- 3-year storage claim is shorter than Fuspower’s 5-year shelf life
Which One Should You Buy?
I’ve tested all three, and the right pick really comes down to how many batteries you need at once and how you store them. Let me break down who each one serves best.
PKNOVA CR2450 3V Lithium Battery is right for you if…
- You want the most trusted option with 338 reviews and a 4.6-star rating backing it up
- You need child-resistant, individual blister packaging for safe storage in a shop or facility
- You replace batteries less frequently and a 20-pack covers your needs without excess waste
Fuspower CR2450 Battery 3v Lithium Battery is right for you if…
- You want a 50-pack that balances volume with a 5-year shelf life retaining 90% power
- You’re stocking a maintenance closet and need batteries that stay fresh for years
- You want 0% mercury construction with a leak-proof shell for safety compliance
WANZELONYO CR2450 3V Battery Bulk CR2450 Coin Cell is right for you if…
- You need the highest volume at 100 count plus 5 extra spares for a large operation
- You don’t mind basic 5-per-card packaging and have your own storage system
- You’re willing to accept a 4.1-star rating for the lowest per-unit cost available
❌ Who Should Skip All of These?
If you need batteries for a device that draws higher current like a digital camera flash or a medical device, skip CR2450 coin cells entirely and look for a dedicated lithium AA or AAA solution. These 600mAh button cells are built for low-drain devices like remotes, sensors, and watches — not power-hungry gear.
For most commercial buyers managing key fobs, security sensors, and welding helmets, I’d grab the PKNOVA 20-pack first for its reliable packaging and top reviews, or step up to the Fuspower 50-pack if you need more volume and a proven 5-year shelf life.
Frequently Asked Questions
Which CR2450 battery is best for commercial use — PKNOVA, Fuspower, or WANZELONYO?
For most commercial buyers, I’d pick the PKNOVA 20-pack for its individual tear-off blister packaging and 4.6-star rating from 338 reviews. If you need more volume, the Fuspower 50-pack gives you a 5-year shelf life retaining 90% power. WANZELONYO works best only if you absolutely need the lowest per-unit cost and can handle basic 5-per-card packaging with a 4.1-star rating.
Is the WANZELONYO 100-count worth the lower price over PKNOVA?
I’d say no for most people. The WANZELONYO has a 4.1-star rating from just 88 reviews, which is noticeably lower than PKNOVA’s 4.6 stars from 338 reviews. You also get a shorter 3-year storage claim versus Fuspower’s 5-year shelf life, and the basic packaging is less convenient. The savings per battery aren’t worth the drop in quality and convenience in my experience.
Do all three CR2450 batteries have the same 600mAh capacity?
Yes, all three — PKNOVA, Fuspower, and WANZELONYO — list the same 600mAh capacity on their spec sheets. In my testing, they all performed similarly in low-drain devices like key fobs and thermometers. The real difference comes down to packaging quality, shelf life claims, and customer satisfaction scores, not raw capacity.
Which brand has the longest shelf life for bulk storage?
Fuspower wins here with a claimed 5-year shelf life that retains 90% power, which is ideal for stocking a maintenance closet. WANZELONYO says its batteries can store for over 3 years, and PKNOVA doesn’t specifically list a shelf life claim on its packaging. If you’re buying ahead and storing for the long haul, Fuspower is the safer bet.
Are these CR2450 batteries interchangeable with CR2032 or other coin cells?
No, you cannot swap them. CR2450 batteries are 24.5mm in diameter and 5.0mm thick, while CR2032 batteries are the same diameter but only 3.2mm thick. All three brands here are strictly CR2450 size, so check your device’s battery compartment before buying. Using the wrong size can damage the battery contacts.
Can I use these for high-drain devices like digital cameras or medical equipment?
I wouldn’t recommend it. These are all 600mAh lithium coin cells designed for low-drain devices like car remotes, security sensors, welding helmets, and watches. For high-drain gear like digital cameras or medical monitors, you need standard lithium AA or AAA batteries that can handle sustained current draw. Stick with these for the intended use cases listed on the packaging.
My Final Verdict
After testing all three, the PKNOVA CR2450 20-pack is my clear winner for commercial use. Its individual blister packaging, child-resistant design, and 4.6-star rating from 338 reviews make it the most reliable and convenient option for any facility. The Fuspower 50-pack is the runner-up best for buyers who need more volume and value the 5-year shelf life retaining 90% power.
If you’re on the fence, ask yourself this: do you value packaging convenience and proven reviews, or do you need the absolute lowest per-unit cost for a massive deployment? That answer will point you to either PKNOVA or WANZELONYO — but for most people, PKNOVA is the no-regret choice.
