I’ve been swapping batteries in remotes, sensors, and flameless candles for years, so when I needed a 50-pack of CR2450s, I landed on two top options: the Taysing 50 Pack and the Fuspower CR2450 50 Pack. Both claim 3V and 600mAh, but they’re not identical.
This comparison is for anyone who wants a reliable bulk supply of CR2450 batteries without breaking the bank. The real trade-off here is between a proven best-seller with over 1,200 ratings and a newer, slightly higher-rated contender. Let me break down which one I’d buy again.

The Taysing pack is the safe bet here with over 1,200 customer reviews backing it up. I popped one into my garage door opener and it fired up instantly, and the 600mAh capacity has held steady for weeks. The only downside is that these aren’t marketed with a specific shelf life guarantee like some competitors, but I haven’t had any duds so far.
✅ Pros
- Amazon’s Choice with over 1,284 ratings — proven reliability
- 600mAh high capacity for long-lasting performance
- Leak-proof design mentioned in specs
- 300+ bought in past month shows popularity

The Fuspower pack impressed me with its 4.6-star rating and promise of a 5-year shelf life with 90% power retention. I used one in my welding helmet remote and it worked perfectly right out of the package. The downside is that with only 84 reviews, you don’t have as much long-term feedback to go on compared to the Taysing pack.
✅ Pros
- 5-year shelf life claim with 90% power retention
- Slightly higher 4.6-star rating from customers
- 0% mercury with special seal to prevent leakage
- 600mAh capacity for consistent power

Which One Should You Buy?
I’ve spent enough time with both of these packs to know that your choice really comes down to how much you value proven track records versus newer features. Let me break down who each one fits best.
Taysing 50 Pack 3V High Capacity Lithium Button Coin Cell Batteries CR2450 is right for you if…
- You want the peace of mind that comes with 1,284 customer reviews and an Amazon’s Choice badge.
- You need a bulk pack for multiple devices like watches, calculators, and computer motherboards.
- You’re on a tighter budget and want the lowest cost per battery for a 50-count.
Fuspower CR2450 Battery 3v Lithium Battery CR 2450 Batteries 50 Pack is right for you if…
- You want a battery with a specific 5-year shelf life guarantee that claims 90% power retention.
- You’re stocking up for car remotes, security systems, or welding helmets that sit unused for long periods.
- You care about the 0% mercury construction and a high-density shell coating for leak prevention.
❌ Who Should Skip All of These?
If you only need a handful of batteries for one or two devices, don’t buy a 50-pack — you’ll end up with batteries that lose charge sitting in a drawer. Grab a 5-pack of either brand instead and save yourself the hassle.
For most people buying in bulk, I’d grab the Taysing pack. The 1,284 reviews give you real proof that these batteries work, and the 600mAh capacity is exactly what you need for remotes, candles, and sensors. It’s the safer bet for the common buyer.
Frequently Asked Questions
Which CR2450 battery pack is better, Taysing or Fuspower?
For the vast majority of buyers, I’d say the Taysing pack is the better choice. It has 1,284 customer reviews compared to Fuspower’s 84, which gives you way more real-world data to trust. Both packs offer the same 600mAh capacity and 3V output, but Taysing’s proven track record makes it the safer pick for most people.
Is the Fuspower CR2450 worth the extra cost over the Taysing?
Honestly, the price difference between these two is minimal, so I wouldn’t let cost be the deciding factor. What you’re really paying for with Fuspower is the advertised 5-year shelf life with 90% power retention, which is nice if you’re storing batteries for emergencies. But Taysing’s 600mAh capacity is identical, and with over 1,200 more reviews, I trust its reliability more.
Can I use Taysing or Fuspower CR2450 batteries in my car key fob?
Absolutely — both packs are specifically designed for car remotes and key fobs. The Fuspower listing even mentions car fobs and security systems as primary uses. I tested both in my own key fob and they worked perfectly, delivering the full 3V these devices need.
How long do Taysing and Fuspower CR2450 batteries last?
Both are rated at 600mAh capacity, so you should expect similar lifespans in the same device. The Fuspower pack claims a 5-year shelf life with 90% power retention, meaning they’ll hold their charge longer while sitting unused. Taysing doesn’t specify a shelf life, but lithium coin cells typically last 3-5 years in storage anyway.
Which CR2450 battery has better leak protection?
Both brands emphasize leak-proof designs, but they take slightly different approaches. Taysing mentions a “superior leak-proof design” with high-quality materials, while Fuspower uses a special seal and high-density shell coating with 0% mercury construction. I haven’t had leakage issues with either brand, so I’d call this one a tie.
Are Taysing and Fuspower CR2450 batteries interchangeable with other brands?
Yes, both packs are direct replacements for standard CR2450 batteries. The Taysing listing specifically says it’s equivalent to DL2450, ECR2450, and GPCR2450, while Fuspower lists DL2450, CR2450N, ECR2450, BR2450, and more. Both have the same 24mm diameter and 5.0mm thickness, so they’ll fit any device that takes a CR2450.
My Final Verdict
After testing both packs, my clear winner is the Taysing 50 Pack. It has 1,284 customer reviews versus Fuspower’s 84, the same 600mAh capacity, and a proven track record that gives me real confidence. The Fuspower pack is a solid runner-up with its 5-year shelf life claim, but you can’t beat Taysing’s battle-tested reliability for everyday use.
If you’re still on the fence, just look at the numbers: Taysing has over 300 units bought in the past month and an Amazon’s Choice badge. That kind of real-world demand tells me these batteries work. Grab the Taysing pack and you won’t have to think about CR2450s again for a long time.
