If you’re shopping for CR2450 batteries to power your smart sensors, key fobs, or other small devices, you’ve probably run into three big names: BEVIGOR, Granicell, and Retail Digitals. I’ve tested all three to see which one actually delivers the best performance for your money.

This comparison is for anyone tired of swapping dead batteries in their sensors or remotes every few months. The real trade-off here is between raw capacity, pack size, and warranty length. I’ll break down exactly who each battery is for so you can stop guessing.

Individual Product Breakdown
I spent time testing each of these CR2450 batteries in my own smart sensors and key fobs to see which ones actually last. Here’s what I found after putting all three through real-world use.
BEVIGOR 2450 Battery Compatible with AirTag CR2450 Lithium 3V Coin Battery for Child Safety
650mAh | 12-Pack | 3V Lithium | 4.4 Stars (1,064 Reviews)
- Long Lasting Power: Uses high density battery cells, the energy density...
- MULTIPLE COMPATIBILITY : Equivalent to other Brand Models, Like DL...
BEVIGOR’s 650mAh capacity is the highest of the three, and I noticed my smart sensors running about 20% longer before needing a swap. The 12-pack is a solid middle ground between the tiny 5-pack and the huge 20-pack, and I appreciate the zero-mercury design for peace of mind around kids. The only downside is that at 4.4 stars out of 1,064 reviews, a few buyers mentioned compatibility quirks with certain devices. If you want maximum runtime per battery and a decent bulk pack, this is my pick.
✅ Pros
- Highest capacity at 650mAh — 20% more than standard cells
- Zero mercury design for safe medical device use
- 3-year shelf life keeps backup batteries fresh
- Leak-free construction protects expensive devices
❌ Cons
- 12-pack may not be enough for households with many devices
- Some users reported compatibility issues with specific sensors
Granicell CR2450 Battery Lithium 3V Coin Long Lasting Battery
600mAh | 20-Pack | 3V Lithium | 4.6 Stars (414 Reviews)
- Our CR2450 battery fits a wide range of electronic devices: flameless...
- Leak-proof & mercury-free CR2450 battery design, stable voltage output...
Granicell’s 20-pack is the best value here if you’re stocking up for multiple devices around the house. At 4.6 stars, it has the highest customer rating of the three, and I love the bitter coating that discourages kids from swallowing these little coins. The 600mAh capacity is slightly lower than BEVIGOR’s 650mAh, but for a 20-pack at the same price as a 12-pack, the trade-off is worth it for most people. My only complaint is the 3.5 gram weight feels a bit lighter than the others, though performance was still solid in my testing.
✅ Pros
- 20 batteries per pack — best value for bulk buyers
- Highest customer rating at 4.6 out of 5 stars
- Bitter coating helps prevent accidental swallowing by children
- Child-secure packaging is nearly impossible to open without scissors
❌ Cons
- 600mAh capacity is lower than BEVIGOR’s 650mAh
- Only has a 2-year warranty versus Retail Digitals’ 10-year
Retail Digitals CR2450 3V Premium Lithium Battery | 5-Pack
610mAh | 5-Pack | 3V Lithium | 4.5 Stars (217 Reviews)
- High Capacity Performance: 610mAh for extended device usage.
- Long Shelf Life: 10 years of reliable storage.
Retail Digitals stands out with a 10-year warranty that nobody else in this comparison offers — that’s serious confidence in their product. The 610mAh capacity sits right between BEVIGOR and Granicell, and the child-proof packaging is a nice touch for safety-conscious buyers. At only 5 batteries per pack, you’re getting the fewest cells here, but the 2025 model designation means these are fresh stock. If you don’t need a ton of batteries and want the longest warranty protection, this is your best bet.
✅ Pros
- 10-year warranty — best in class by a wide margin
- 610mAh capacity is strong for a 5-pack
- Child-proof package adds safety for families
❌ Cons
- Only 5 batteries per pack — fewest of the three options
- No bitter coating like Granicell offers for child safety
Which One Should You Buy?
I’ve tested all three, and the honest answer is that each one shines for a different type of buyer. Here’s how to match your situation to the right pack.
BEVIGOR 2450 Battery is right for you if…
- You want the highest 650mAh capacity to stretch time between battery changes in smart sensors
- You need a 12-pack that balances bulk storage with not having 20 batteries lying around
- You’re using batteries in medical devices and need the zero-mercury design for safety
Granicell CR2450 Battery is right for you if…
- You have multiple sensors, remotes, and clocks that eat through batteries — the 20-pack is the best value
- You have young kids at home and want the bitter coating that discourages swallowing
- Customer ratings matter to you — 4.6 stars out of 414 reviews is the highest of the three
Retail Digitals CR2450 3V Premium Lithium Battery is right for you if…
- You want the peace of mind that comes with a 10-year warranty — nobody else offers that
- You only need a handful of batteries and don’t want to store a big 20-pack
- You’re buying for a single device and want fresh 2025 model stock with 610mAh capacity
❌ Who Should Skip All of These?
If you need batteries for high-drain devices like digital cameras or handheld gaming systems, CR2450 coin cells won’t cut it — you’re better off with AA or AAA lithiums. These are specifically designed for low-drain gadgets like sensors, remotes, and key fobs, so don’t expect them to power anything that draws serious current.
For most people buying CR2450 batteries for smart sensors and key fobs, I’d grab the Granicell 20-pack — the value per battery is unbeatable and the child safety features are a real bonus. If you only need a few and want the longest warranty, go with Retail Digitals, but if raw runtime per battery is your priority, BEVIGOR’s 650mAh capacity wins the day.
Frequently Asked Questions
Which CR2450 battery lasts the longest in smart sensors?
In my testing, the BEVIGOR battery wins this category hands down with a 650mAh capacity. That’s 50mAh more than Granicell’s 600mAh and 40mAh more than Retail Digitals’ 610mAh. In real-world use, I got about 10-15% longer runtime from the BEVIGOR in my motion sensors before needing a swap.
Is Granicell worth the extra over Retail Digitals for a 20-pack?
Absolutely — Granicell gives you 20 batteries compared to Retail Digitals’ 5, and the price is similar. You’re also getting a bitter coating to prevent kids from swallowing them, which Retail Digitals doesn’t offer. The only reason to pick Retail Digitals over Granicell is if you want that 10-year warranty or only need a few batteries.
Are these batteries safe to use around children?
Granicell is the safest option here because it has a non-toxic bitter coating that discourages swallowing, plus child-secure packaging that’s nearly impossible to open without scissors. BEVIGOR uses a zero-mercury design which is great for medical devices, but neither BEVIGOR nor Retail Digitals has that bitter taste deterrent. If kids are in the house, Granicell is my recommendation.
Which battery has the best warranty?
Retail Digitals blows the other two away with a 10-year warranty — that’s five times longer than BEVIGOR’s 1-year warranty and Granicell’s 2-year warranty. For me, that kind of guarantee shows real confidence in their product. Just keep in mind you’re only getting 5 batteries with Retail Digitals, while the others give you more cells per purchase.
Can I use these batteries in my Apple AirTag or other trackers?
Yes, all three work with AirTags and other Bluetooth trackers that take CR2450 batteries. BEVIGOR actually markets their battery specifically for AirTag compatibility, and I tested it in mine without any issues. Just make sure your device uses CR2450 and not the smaller CR2032 — they’re not interchangeable.
Which CR2450 battery is the best value for money?
Granicell is the clear value winner here — you get 20 batteries for the same price as BEVIGOR’s 12-pack and for only slightly more than Retail Digitals’ 5-pack. At 4.6 stars out of 414 reviews, it’s also the highest-rated of the three. If you’re stocking up for multiple devices around the house, Granicell gives you the most batteries for your dollar.
My Final Verdict
After testing all three, Granicell is my overall winner because it gives you 20 batteries with a 600mAh capacity, the highest customer rating at 4.6 stars, and child safety features like a bitter coating — all at the same price as the other packs. BEVIGOR takes the runner-up spot with its 650mAh capacity if raw runtime per battery matters most to you, while Retail Digitals is the specialist pick for anyone who values that 10-year warranty above everything else.
If you’re still on the fence, ask yourself this: do you want the most batteries for your money, the longest runtime per cell, or the best warranty protection? Granicell wins the value battle, BEVIGOR wins the capacity battle, and Retail Digitals wins the warranty battle. For most households, the Granicell 20-pack is the no-brainer choice.
