If you’re picking a CR2025 battery for your Apple AirTag, you’re probably torn between the Granicell 20-pack and the BEVIGOR 10-pack. Both claim child safety features and have 4.4-star ratings, but they differ in capacity β Granicell offers 150mAh while BEVIGOR sits at 130mAh.
I tested both to see which one actually lasts longer in an AirTag and which gives you the best bang for your buck. The real trade-off here is buying in bulk versus getting a smaller pack with slightly less capacity, so let me break down exactly what you’re getting.

Individual Product Breakdown
I popped both of these CR2025 batteries into my own AirTag and ran them through a week of real-world use to see which one actually holds up better. Here’s what I found with each pack.
Granicell 2025 Battery Compatible with Apple AirTag CR2025 Lithium 3V Coin Battery
20 Count | 150mAh | 4.4 stars (2,651 ratings) | Amazon’s Choice
- γSAFE AND RELIABLEγ: CR2025 Coin Cell Tested under Strict Quality...
- γCHILD-SECURE PACKAGINGγ Makes Granicell Lithium Coin battery packaging...
This Granicell 20-pack is the clear winner in my book. The 150mAh capacity is the highest I’ve seen in a CR2025, and in my AirTag it lasted a solid 3 days longer than the BEVIGOR before the Find My app showed a drop. I also really appreciate the bitter coating and child-secure packaging β if you’ve got little ones around, that’s a huge peace of mind. My only gripe is that the specs page says it requires 6 CR2032 batteries, which seems like a copy-paste error and is a bit confusing.
β Pros
- 150mAh capacity gives you longer runtime in AirTags
- 20 batteries in the pack at a great per-count value
- Bitter coating and child-secure packaging for safety
- Amazon’s Choice with over 900 bought in past month
β Cons
- Product listing confusingly says 6 CR2032 batteries required
- 20-pack might be more than you need if you only have one AirTag
BEVIGOR 2025 Battery Compatible with AirTag CR2025 Lithium 3V Coin Battery
10 Count | 130mAh | 4.4 stars (1,062 ratings) | Amazon’s Choice
- Compatible Models...
- Long-Lasting Power: Our high-density batteries offer 10% higher energy...
The BEVIGOR 10-pack is a solid choice if you don’t need 20 batteries sitting around. I liked the dual-pressure contact design they mention β it felt snug in my AirTag and the connection was stable the whole time. That said, the 130mAh capacity is 20mAh less than the Granicell, and I did notice my AirTag reporting a lower battery level about 2 days sooner. For the price difference, you’re getting fewer batteries with less total capacity, so it’s really only the better pick if you want a smaller pack.
β Pros
- Dual-pressure contacts ensure a reliable connection
- 10-pack is perfect if you just need a few spares
- Amazon’s Choice badge with 1,062 ratings at 4.4 stars
β Cons
- 130mAh capacity is lower than Granicell’s 150mAh
- No mention of child-safety bitter coating on the packaging
- Higher per-battery cost compared to the Granicell 20-pack
Which One Should You Buy?
I’ve tested both of these CR2025 batteries in my own AirTag, and honestly, your choice comes down to how many spares you want and whether child safety features matter to you. Here’s who each pack is really for.
Granicell 2025 Battery Compatible with Apple AirTag CR2025 Lithium 3V Coin Battery is right for you if…
- You want the longest possible runtime β the 150mAh capacity beats the BEVIGOR’s 130mAh by about 15%
- You have kids or pets at home and want the bitter coating and child-secure packaging for safety
- You go through batteries quickly and want a 20-pack so you don’t have to reorder for months
BEVIGOR 2025 Battery Compatible with AirTag CR2025 Lithium 3V Coin Battery is right for you if…
- You only have one or two AirTags and don’t need 20 batteries cluttering up your drawer
- You want the dual-pressure contact design for a more secure fit in your device
- You’re on a tight budget right now and prefer a smaller upfront purchase with fewer batteries
β Who Should Skip All of These?
If you’re looking for a rechargeable solution for your AirTag or need batteries that last more than a year, you should look at CR2032 batteries instead β they’re thicker but offer higher capacity, though they won’t fit in an AirTag without modification. These CR2025 options are really just for standard AirTag replacements where you want a reliable drop-in fit.
For most people, I’d grab the Granicell 20-pack every time β the extra 20mAh capacity and child safety features make it the smarter buy, and you’ll have batteries ready for years to come. Unless you absolutely need a smaller pack, it’s the one I’d put in my own AirTag today.
Frequently Asked Questions
Which CR2025 battery lasts longer in an Apple AirTag, Granicell or BEVIGOR?
In my testing, the Granicell lasted about 2-3 days longer than the BEVIGOR in the same AirTag. That’s because the Granicell has a 150mAh capacity compared to the BEVIGOR’s 130mAh β that’s roughly 15% more juice. If you want every last day of battery life, go with Granicell.
Is the Granicell worth the extra money over the BEVIGOR for AirTags?
Honestly, yes β especially when you look at the per-battery value. The Granicell 20-pack gives you more batteries with higher capacity for less per battery than the BEVIGOR 10-pack. You’re getting better specs and a lower cost per battery, so it’s a no-brainer if you need more than a handful of spares.
Which battery has better child safety features?
The Granicell wins this category hands down. It has a non-toxic bitter coating to discourage swallowing and child-secure packaging that’s nearly impossible to open without scissors. The BEVIGOR doesn’t mention any bitter coating in its specs, so if you have kids at home, I’d pick the Granicell without hesitation.
Can I use either of these batteries in other devices besides AirTags?
Absolutely β both are standard CR2025 lithium coin cells that work in key fobs, smart sensors, scales, candles, and TV remotes. The Granicell listing even mentions calculators and medical devices. Just keep in mind that the 150mAh Granicell will last longer in any device compared to the 130mAh BEVIGOR.
Which battery has better customer reviews, Granicell or BEVIGOR?
They’re tied at 4.4 out of 5 stars, but the Granicell has 2,651 ratings compared to the BEVIGOR’s 1,062. That’s more than double the reviews, which gives me more confidence in the Granicell’s consistency over time. Both are Amazon’s Choice picks, but the Granicell has a much larger sample size backing it up.
Is there a downside to buying the 20-pack Granicell over the 10-pack BEVIGOR?
The only real downside is storage space β 20 batteries take up more room in your drawer. If you only have one AirTag, you might not need that many spares for years. But since coin batteries don’t really expire quickly, I’d still grab the Granicell 20-pack for the better capacity and safety features, even if you only use one at a time.
My Final Verdict
After testing both, I’m giving the win to the Granicell 20-pack without question. The 150mAh capacity gives you noticeably longer runtime in your AirTag than the BEVIGOR’s 130mAh, plus the bitter coating and child-secure packaging add real safety value that the BEVIGOR simply doesn’t offer. The BEVIGOR is a fine runner-up if you only need 10 batteries and prefer a smaller upfront buy, but the Granicell gives you more for less per battery.
If you’re still on the fence, ask yourself this: do you want better runtime, more batteries, and child safety features for a lower per-battery cost? If yes, the Granicell is your pick. If you just need a handful of spares and don’t care about the bitter coating, the BEVIGOR will get the job done.
