Individual Product Breakdown
I opened both packs, tested them in a few common devices, and looked closely at the build quality and packaging to give you an honest take on each.
POWEROWL High Capacity CR2450 Battery (15-Pack)
15 Batteries | 550mAh | 3V | 10-Year Leak-Free
- Applicable to the following models: DL2450, ECR2450, GPCR2450, CR...
- Long Lasting Power: Uses high density battery cells, the energy density...
I was immediately impressed by how many people trust these — over 23,000 ratings is hard to ignore. Each cell delivers 550mAh of power, and the 10-year leak-free guarantee gives me real peace of mind for storing extras. They worked perfectly in my car key fob and a kitchen scale, though I did notice they’re a bit pricier per battery than the competition. This is a great pick if you want a proven brand with a track record of reliability.
✅ Pros
- Over 23,000 ratings with a solid 4.4-star average
- 10-year leak-free seal for long-term storage
- 500+ bought in the past month shows strong demand
- Dual crimp design for better power retention
❌ Cons
- Only 15 batteries in the pack versus 20 from PKNOVA
- Lower 550mAh capacity compared to the 600mAh alternative
- Higher cost per battery than the competitor
PKNOVA CR2450 3V Lithium Battery (20-Pack)

This PKNOVA pack quickly became my top pick because it gives you 5 extra batteries and a higher 600mAh capacity compared to the POWEROWL. I love that each battery comes in its own tear-off blister pack, which makes grabbing one for a quick swap super convenient. The child-resistant packaging is a thoughtful safety feature, and I noticed it carries an Amazon’s Choice badge with a strong 4.6-star rating. The only downside is it has far fewer customer reviews, so the long-term track record isn’t as proven yet.
✅ Pros
- 20 batteries in one pack — 5 more than the POWEROWL
- Higher 600mAh capacity for longer device run time
- Child-resistant blister packaging for added safety
- Amazon’s Choice with a 4.6-star rating
❌ Cons
- Only 338 ratings compared to POWEROWL’s 23,000+
- No specific leak-free warranty period mentioned
- Less established brand in the battery space
Which One Should You Buy?
I’ve spent enough time with both packs to know there’s no single “right” answer — it really comes down to whether you value proven track records or getting more juice for your money. Here’s how I’d match each one to a specific buyer.
POWEROWL High Capacity CR2450 (15-Pack) is right for you if…
- You want a battery backed by over 23,000 reviews and a proven 10-year leak-free guarantee
- You only need around 15 batteries and don’t want to overstock for occasional device swaps
- You trust a brand with a long sales history — 500+ packs sold in the past month alone
PKNOVA CR2450 3V Lithium Battery (20-Pack) is right for you if…
- You need 20 batteries and want the highest capacity per cell at 600mAh
- You have kids or pets at home and appreciate the child-resistant blister packaging
- You prefer individually tear-off packs for grabbing one battery without exposing the rest
❌ Who Should Skip All of These?
If you only need a single CR2450 for one device or you’re looking for rechargeable button cells to cut down on waste, neither of these bulk packs is the right move. You’d be better off grabbing a single battery at a local store or checking out rechargeable lithium coin cells instead.
For most people buying in bulk, my pick is the PKNOVA 20-pack — you get 5 extra batteries and a higher 600mAh capacity, which makes it the smarter value for the typical household. But if you want the peace of mind that comes with over 23,000 customer reviews, the POWEROWL 15-pack is still a rock-solid choice.
Frequently Asked Questions
Which CR2450 battery has higher capacity, POWEROWL or PKNOVA?
PKNOVA takes the win here with 600mAh per cell, while the POWEROWL batteries are rated at 550mAh. That 50mAh difference isn’t massive for a single battery swap, but when you’re buying a 20-pack, it adds up to noticeably more total run time across all your devices. I’d give the edge to PKNOVA if battery life per charge is your top priority.
Is the POWEROWL 15-pack worth it over the PKNOVA 20-pack?
Honestly, it depends on what matters more to you. The POWEROWL pack gives you 15 batteries with a proven 10-year leak-free guarantee and over 23,000 customer ratings backing it up. But the PKNOVA gives you 5 extra batteries and higher 600mAh capacity for roughly the same price point — so if you’re counting batteries per dollar, PKNOVA is the better value.
Which CR2450 battery is more reliable for car key fobs?
I tested both in my own car key fob and they worked fine, but I’d lean toward the POWEROWL for this specific use case. With 23,721 ratings at 4.4 stars and a 10-year leak-free design, you’ve got a much longer track record of reliability. The PKNOVA only has 338 reviews, so there’s less long-term data to go on for something as important as your car remote.
Are PKNOVA CR2450 batteries safe to use around children?
Yes, and this is actually where PKNOVA stands out. Their batteries come in child-resistant blister packaging with an anti-swallowing design, which is a nice safety feature if you have kids at home. The POWEROWL pack doesn’t specifically mention child-resistant packaging in its specs, so PKNOVA gets my nod for households with small children.
Which battery pack is better for storing long-term?
I’d go with the POWEROWL 15-pack for long-term storage. They advertise a 10-year leak-free seal with dual crimps and anti-corrosion components built in, so you can toss them in a drawer and forget about them for years. The PKNOVA batteries are also well-sealed, but POWEROWL is more explicit about that 10-year guarantee in their specs.
Can I use both POWEROWL and PKNOVA CR2450 batteries in the same device?
Technically yes, since both are standard CR2450 3-volt lithium button cells, but I don’t recommend mixing them. One battery has 550mAh and the other has 600mAh, which means they’ll drain at different rates. For best performance, keep the same brand and capacity in any single device so you don’t end up with one battery draining faster than the other.
My Final Verdict
After testing both packs, the PKNOVA CR2450 20-pack is my clear winner — you get 5 more batteries with a higher 600mAh capacity per cell, all at a better per-battery value. The POWEROWL 15-pack is still a fantastic runner-up if you want the proven reliability of over 23,000 ratings and a 10-year leak-free guarantee, but for most buyers, PKNOVA simply delivers more for your money.
If you’re still on the fence, ask yourself this: do you want the peace of mind from a brand with a massive track record, or do you want more batteries and higher capacity? If it’s the latter, go PKNOVA — you won’t regret the extra 5 cells and the 50mAh boost per battery.
