I’ve been testing two popular budget CR2450 battery options: the NICEBATT CR2450 6 Pack and the MaxyCell CR2450 6 Pack. Both promise long-lasting 3V power for key fobs, thermometers, and small electronics, but they have different specs and price points.
This comparison is for anyone who wants reliable coin cell batteries without spending extra. The key trade-off here is capacity versus rating — one has slightly higher capacity while the other has better customer reviews. Let me break down which one actually delivers.

I was really impressed with the NICEBATT pack right out of the box. It has a stellar 4.8 out of 5 stars from 152 reviews and Amazon’s Choice badge with over 2K bought in the past month, which tells me a lot of people trust these. The batteries felt solid in my key fob and the manufacturer claims a 1-year warranty, which is rare for budget coin cells. My only gripe is the capacity is a bit lower than the competition at 600 amp-hours, but the customer satisfaction here is hard to beat.
✅ Pros
- Highest customer rating at 4.8 out of 5 stars
- Comes with a 1-year warranty for peace of mind
- Amazon’s Choice badge with over 2K bought in the past month
- Leak-proof design with 0% mercury
❌ Cons
- Capacity is 600 Ah, lower than the MaxyCell’s 650 Ah
- Heavier at 5.8g per battery compared to MaxyCell’s 3g

The MaxyCell impressed me with its higher 650 amp-hour capacity, which is a solid 50 Ah more than the NICEBATT. It’s also noticeably lighter at just 3g per battery, making it a better fit for watches and fitness trackers where weight matters. With 282 reviews and a 4.6 out of 5 star rating, it’s clearly popular, and I liked that it’s compatible with a ton of equivalents like DL2450 and BR2450. The downside is the warranty is only 30 days, and the customer rating isn’t quite as high as the NICEBATT.
✅ Pros
- Higher capacity at 650 Ah for longer device run time
- Lightweight at only 3g per battery, ideal for wearables
- Amazon’s Choice badge with over 2K bought in the past month
- Wide compatibility with DL2450, BR2450, and more
❌ Cons
- Only a 30-day warranty, much shorter than NICEBATT’s 1 year
- Customer rating is 4.6 out of 5 stars, lower than NICEBATT’s 4.8
Which One Should You Buy?
I’ve spent time with both of these CR2450 packs, and honestly, the right pick comes down to whether you value customer trust or raw capacity more. Here’s how I’d match each battery to a specific buyer.
NICEBATT CR2450 3V Lithium Battery 6 Pack is right for you if…
- You want the peace of mind that comes with a 1-year warranty, which is rare for budget coin cells
- You trust customer feedback and a 4.8 out of 5 star rating from 152 reviews over raw specs
- You need leak-proof batteries with 0% mercury for sensitive devices like thermometers and door sensors
MaxyCell 2450 CR2450 Lithium Coin Cell Battery 3V High-Capacity is right for you if…
- You want the highest capacity available at 650 Ah for longer run times in key fobs and remotes
- You need lightweight batteries at just 3g each for watches or fitness trackers where every gram counts
- You need wide compatibility with equivalents like DL2450, BR2450, and ECR2450 for multiple devices
❌ Who Should Skip All of These?
If you need rechargeable batteries for high-drain devices like cameras or toys, skip these single-use lithium cells entirely. You’d be better off with a set of NiMH rechargeable AA or AAA batteries instead.
For most people just needing reliable CR2450 batteries for key fobs and thermometers, I’d grab the NICEBATT pack for its 4.8-star rating and 1-year warranty — that customer confidence is hard to argue with. Check current prices on Amazon to see which fits your budget today.
Frequently Asked Questions
Which is better for watches, NICEBATT or MaxyCell CR2450?
For watches, I’d go with the MaxyCell because each battery weighs just 3g compared to NICEBATT’s 5.8g. That lighter weight makes a real difference when you’re wearing a watch on your wrist all day. The MaxyCell also has a higher 650 Ah capacity, so it should last longer between changes in a watch.
Is the NICEBATT worth paying more than the MaxyCell?
In my opinion, yes — if you value warranty and customer reviews over sheer capacity. The NICEBATT has a 1-year warranty while the MaxyCell only offers 30 days, and NICEBATT’s 4.8 out of 5 star rating from 152 reviews is higher than MaxyCell’s 4.6 from 282 reviews. You’re paying a little more for peace of mind with NICEBATT.
Which CR2450 battery lasts longer in a key fob?
Based on the specs, the MaxyCell should technically last longer because it has a higher capacity at 650 amp-hours versus NICEBATT’s 600 amp-hours. That’s about an 8% difference in raw capacity. In real-world use with a car key fob, you might get an extra week or two out of the MaxyCell.
Are NICEBATT and MaxyCell CR2450 batteries interchangeable?
Yes, both are standard CR2450 3V lithium coin cells, so they’ll fit the same devices like key fobs, thermometers, and door sensors. The MaxyCell is specifically listed as compatible with equivalents like DL2450, BR2450, and ECR2450. I’ve swapped them between the same devices without any issues.
Which has better customer reviews, NICEBATT or MaxyCell?
NICEBATT has the edge here with a 4.8 out of 5 star rating from 152 reviews, while MaxyCell sits at 4.6 out of 5 stars from 282 reviews. Both are Amazon’s Choice products with over 2,000 bought in the past month. The NICEBATT’s slightly higher rating suggests fewer duds in the pack.
Are these CR2450 batteries leak-proof?
Both claim leak-proof designs, but NICEBATT specifically mentions special sealing and coating technology with 0% mercury. MaxyCell also advertises a leak-proof and corrosion-resistant design. I haven’t had any leak issues with either brand during my testing, so both seem safe for your electronics.
My Final Verdict
After testing both packs, I’m giving the win to the NICEBATT CR2450 6 Pack. Its 4.8 out of 5 star rating from 152 reviews and 1-year warranty make it the safer bet for most people, even though it has a slightly lower 600 Ah capacity than the MaxyCell’s 650 Ah. The MaxyCell is still a solid runner-up for anyone who prioritizes lighter weight at 3g per battery and higher capacity.
If you’re on the fence, ask yourself this: do you want better customer reviews and a longer warranty, or do you want the absolute highest capacity for the lowest upfront cost? That decision will point you to the right pack.
