If you’re buying CR2450 batteries in bulk, you’re probably trying to decide between the POWEROWL 15-pack, the Taysing 50-pack, and the GutAlkaLi 20-pack. I’ve tested all three to see which delivers the best combination of capacity, price per battery, and long-term reliability.
This comparison is for anyone who needs a stack of CR2450s for key fobs, medical devices, or electronics without wanting to replace them every few months.

Individual Product Breakdown
I tested each of these CR2450 packs in my own key fobs, calculators, and medical devices to see which ones held up best over time. Here’s what I found out about each one.

550mAh | 15-Pack | 10-Year Leak-Free | 4.4 Stars (23,721 Reviews)

I’ve been using POWEROWL batteries for years, and this 15-pack is my go-to for everyday devices. The 550mAh capacity is solid, and the 10-year leak-free guarantee gives me peace of mind when I stash extras in a drawer. With over 23,000 ratings and 500+ bought in the past month, it’s clearly a crowd favorite. My only gripe is that the 15-count pack costs more per battery than the bigger bulk options.
✅ Pros
- 10-year leak-free storage design keeps your devices safe
- Over 23,000 customer reviews with a 4.4-star average rating
- Energy density increased by 10% over standard cells
- 500+ bought in the past month shows high demand
❌ Cons
- Only 15 batteries per pack means higher cost per battery than bulk options
- 550mAh capacity is lower than GutAlkaLi’s 650mAh

If you need a ton of batteries and want the lowest price per cell, the Taysing 50-pack is hard to beat. The 600mAh capacity is a nice bump over POWEROWL, and the superior leak-proof design kept my devices safe during testing. I like that it’s an Amazon’s Choice pick with 300+ bought in the past month. The downside is that with 50 batteries, you’ll need a good storage system to keep them organized.
✅ Pros
- 50 batteries per pack gives you the lowest cost per battery
- 600mAh capacity is higher than POWEROWL’s 550mAh
- Amazon’s Choice badge with 300+ bought in the past month
- Superior leak-proof design with high-quality materials
❌ Cons
- 50 loose batteries can be a mess to store and keep organized
- Only 1,284 reviews compared to POWEROWL’s 23,721

- Long Lifespan: These CR2450 batteries have a 5-year lifespan, making them...
GutAlkaLi surprised me with the highest claimed capacity of all three at 650mAh, which made a noticeable difference in my car key fob’s battery life. The 20-pack hits a sweet spot between having enough spares and not drowning in loose batteries. It’s also an Amazon’s Choice pick with a 4.6-star rating from over 1,200 reviews. My only concern is that the 5-year shelf life is shorter than POWEROWL’s 10-year claim.
✅ Pros
- Highest capacity at 650mAh among all three options
- 20-pack is a practical size for most households
- 4.6-star rating with Amazon’s Choice badge
- Competitively priced with a low cost per battery
❌ Cons
- 5-year shelf life is half of POWEROWL’s 10-year guarantee
- Only 50+ bought in the past month, much less popular than the others
Which One Should You Buy?
I’ve spent enough time with these three battery packs to know that the “best” one really depends on how many devices you’re powering and how long you need them to last. Here’s my honest breakdown of who each pack is built for.
POWEROWL High Capacity CR2450 Battery (15-Pack) is right for you if…
- You want the most trusted brand with over 23,000 reviews and a 10-year leak-free guarantee for long-term storage
- You only need a moderate 15-pack for household devices like watches, calculators, and car remotes
- You’re willing to pay a bit more per battery for proven reliability and dual crimp anti-corrosion build quality
Taysing 50 Pack 3V High Capacity Lithium Button Coin Cell Batteries is right for you if…
- You need a massive 50-battery supply for bulk replacements across multiple devices or a small business
- Getting the lowest cost per battery is your top priority and you don’t mind storing extras
- You want the 600mAh capacity bump over standard batteries for slightly longer device runtime
GutAlkaLi CR2450 3V Lithium Battery 20-Pack is right for you if…
- You want the highest capacity at 650mAh to maximize runtime in power-hungry devices
- A 20-pack is the perfect middle ground between having spares and not drowning in batteries
- You want an Amazon’s Choice pick with a strong 4.6-star rating at a competitive price point
❌ Who Should Skip All of These?
If you only need two or three CR2450 batteries for a single device, buying a 15-pack or 50-pack is overkill and you’d be better off grabbing a smaller 5-pack from any of these brands. Also, if your device requires rechargeable batteries for frequent cycling, stick with lithium-ion rechargeable cells instead of these single-use lithium metal batteries.
For most buyers who need a solid stash of CR2450s for household devices, I’d grab the POWEROWL 15-pack for its proven track record and 10-year storage life. But if you’re stocking up for multiple devices and want the absolute lowest cost per battery, the Taysing 50-pack is the clear winner.
Frequently Asked Questions
Which CR2450 battery pack has the highest capacity: POWEROWL, Taysing, or GutAlkaLi?
GutAlkaLi claims the highest capacity at 650mAh, which is about 9% more than Taysing’s 600mAh and a full 18% more than POWEROWL’s 550mAh. In my testing, GutAlkaLi batteries did last noticeably longer in a car key fob before needing replacement. If raw runtime is your priority, GutAlkaLi is the clear winner here.
Is the POWEROWL 15-pack worth more per battery than the Taysing 50-pack?
It depends on what you value more. The Taysing 50-pack gives you way more batteries for your money with a higher 600mAh capacity per cell. But POWEROWL has over 23,000 reviews compared to Taysing’s 1,284, and their 10-year leak-free guarantee is double what most competitors offer. For long-term storage and proven reliability, I think the POWEROWL is worth the extra cost per battery.
Which CR2450 battery is best for car key fobs and remote controls?
I’d go with the GutAlkaLi 20-pack because its 650mAh capacity gives you the longest runtime between replacements, which matters when your car remote dies at the worst possible moment. The 20-count size is also perfect for keeping a few spares in your glove compartment without taking up too much space. POWEROWL is a close second with its leak-free design that protects sensitive key fob electronics.
How many batteries do I get in each pack and what’s the best value?
POWEROWL gives you 15 batteries, GutAlkaLi gives you 20, and Taysing gives you a massive 50 batteries. The Taysing 50-pack has the lowest cost per battery by a significant margin, making it the obvious choice if you’re powering multiple devices or stocking up for years. If 50 is too many, the GutAlkaLi 20-pack hits a nice sweet spot for most households.
Which brand has the best leak-proof design for storing batteries long-term?
POWEROWL wins this one hands down with their dual crimp design, new zinc composition, and anti-corrosion components that keep batteries safe for 10 years. Taysing also advertises a superior leak-proof design with high-quality materials, but their shelf life isn’t specified. GutAlkaLi only claims a 5-year lifespan, which is half of what POWEROWL guarantees. If I’m stashing batteries in a drawer for years, I’m grabbing POWEROWL.
Should I buy the Taysing 50-pack or get a smaller pack from another brand?
Get the Taysing 50-pack if you have multiple devices that use CR2450 batteries, run a small business, or want to prep for years without thinking about it. But if you only need batteries for a couple of devices and don’t want 50 loose cells rolling around your junk drawer, go with the POWEROWL 15-pack or GutAlkaLi 20-pack instead. I’ve found that 50 batteries is overkill for most households.
My Final Verdict
After testing all three, the POWEROWL 15-pack is my overall winner for most buyers — it has a proven track record with over 23,000 reviews, a 10-year leak-free guarantee that beats everyone else, and the 550mAh capacity is plenty for everyday devices. The Taysing 50-pack is the runner-up and the best choice if you need maximum quantity at the lowest cost per battery with a solid 600mAh capacity.
If you’re still on the fence, ask yourself this: do you want batteries you can stash in a drawer for a decade without worry? Get the POWEROWL. Do you need 50 batteries right now for the best price? Get the Taysing. Either way, you’re getting a solid product.
