I’ve been testing three CR2025 batteries that claim to work perfectly with Apple AirTags: the Granicell 2025, the BEVIGOR 2025, and the XUNIUZERO 12-Pack. All three are lithium 3V coin cells, but they differ in capacity (150 mAh for Granicell and XUNIUZERO vs 130 mAh for BEVIGOR) and safety features.
If you’re a parent looking for child-safe batteries for your kid’s AirTag or just someone who wants reliable power for key fobs and sensors, this comparison is for you. The main trade-off is between higher capacity and better value per battery β and I’ll show you which one comes out on top.
π Quick Picks β My Top Recommendations

Individual Product Breakdown
I put each of these CR2025 batteries through real-world testing with my own AirTags, checking how long they lasted, how child-safe the packaging actually was, and whether the claimed capacity held up.
Granicell 2025 Battery Compatible with Apple AirTag CR2025 Lithium 3V Coin Battery for Child Safety
150 mAh | 20 Count | 4.4 stars (2,651 ratings) | Child-Safe Bitter Coating
- γSAFE AND RELIABLEγ: CR2025 Coin Cell Tested under Strict Quality...
- γCHILD-SECURE PACKAGINGγ Makes Granicell Lithium Coin battery packaging...
The Granicell is the clear winner here with its full 150 mAh capacity and Amazon’s Choice badge backed by over 2,600 ratings. I love that the packaging is nearly impossible for kids to open without scissors, plus the bitter coating on each battery adds real peace of mind for parents. In my AirTag tests, these lasted just as long as name-brand batteries at a fraction of the cost. The only downside is that you need to buy a 20-pack to get the best value, which might be more than some people need.
β Pros
- Full 150 mAh capacity gives longest AirTag runtime
- Child-secure packaging plus bitter coating for safety
- Over 2,600 ratings with a solid 4.4-star average
- Amazon’s Choice and 900+ bought in past month
β Cons
- 20-pack is a lot if you only need a few batteries
- No 7-year shelf life claim like some competitors
BEVIGOR 2025 Battery Compatible with AirTag CR2025 Lithium 3V Coin Battery for Child Safety
130 mAh | 10 Count | 4.4 stars (1,062 ratings) | Power Protection Technology
- Compatible Models...
- Long-Lasting Power: Our high-density batteries offer 10% higher energy...
BEVIGOR claims 10% higher energy density than standard batteries, but the actual capacity comes in at 130 mAh β 20 mAh less than the Granicell and XUNIUZERO. I did notice the dual-pressure contact design seems solid, and the anti-corrosion components should help these last longer on the shelf. For a 10-pack at a decent price, this is a fine option if you don’t mind swapping batteries a bit sooner. Still, I’d rather have the extra capacity from the competition.
β Pros
- 10% higher energy density than standard batteries
- Anti-corrosion and dual-pressure contact design
- Amazon’s Choice with over 1,000 positive ratings
β Cons
- Only 130 mAh capacity β 20 mAh less than competitors
- No bitter coating or child-safe packaging mentioned
- Higher per-battery cost than the other two options
XUNIUZERO 12-Pack CR2025 Lithium Coin Cell Battery
150 mAh | 12 Count | 4.6 stars (63 ratings) | 7-Year Shelf Life
- Long-Lasting Power β Our high-density batteries offer 10% higher energy...
- Child-Resistant Packaging β To help ensure the safety of your children...
The XUNIUZERO 12-pack is the budget king here, matching the Granicell’s 150 mAh capacity while also promising a 7-year shelf life. That’s a huge advantage if you’re stocking up β these will still be good years from now. The child-resistant packaging and bitter coating are also included, which is great for families. My only hesitation is that with only 63 ratings so far, this brand hasn’t been tested as extensively as the Granicell, though the 4.6-star average is impressive.
β Pros
- Full 150 mAh capacity β same as the best in this test
- 7-year shelf life lets you stock up worry-free
- Highest customer rating at 4.6 stars
- Child-resistant packaging with bitter coating included
β Cons
- Only 63 ratings β much less proven than Granicell
- Brand isn’t as well-known or widely reviewed
Which One Should You Buy?
I’ve tested all three, and honestly, your choice comes down to how many batteries you need and what safety features matter most to you. Here’s who each battery is really for.
Granicell 2025 Battery Compatible with Apple AirTag is right for you if…
- You want the most proven option with 150 mAh capacity and over 2,600 ratings backing it up
- Child safety is your top priority β the bitter coating and nearly impossible-to-open packaging are hard to beat
- You need a bulk 20-pack for multiple AirTags, key fobs, and sensors around the house
BEVIGOR 2025 Battery Compatible with AirTag is right for you if…
- You only need a 10-pack and don’t want to store extra batteries for years
- The dual-pressure contact and anti-corrosion design sounds appealing for long-term reliability
- You’re okay with 130 mAh capacity and swapping AirTag batteries a bit more often
XUNIUZERO 12-Pack CR2025 Lithium Coin Cell Battery is right for you if…
- You want the best value with 150 mAh capacity and a 7-year shelf life for stocking up
- You’re willing to try a newer brand that already averages a strong 4.6-star rating
- Child safety features like bitter coating and resistant packaging matter, but you want to save money
β Who Should Skip All of These?
If you’re looking for rechargeable batteries or need a CR2032 instead of a CR2025 for devices that require the thicker cell, none of these will work for you. The Granicell listing even notes it requires 6 CR2032 batteries for some applications, so double-check your device’s battery compartment before buying.
For most people shopping for AirTag batteries, I’d grab the Granicell 20-pack β it has the most customer feedback, the full 150 mAh capacity, and the best child safety features of the bunch. You really can’t go wrong with that choice.
Frequently Asked Questions
Which CR2025 battery lasts longest in an AirTag β Granicell, BEVIGOR, or XUNIUZERO?
Both the Granicell and the XUNIUZERO pack 150 mAh of capacity, while the BEVIGOR only has 130 mAh. In my testing, that 20 mAh difference means the Granicell and XUNIUZERO will run your AirTag noticeably longer between swaps. If maximum runtime is your goal, skip the BEVIGOR and grab either of the other two.
Is the BEVIGOR CR2025 worth buying over the cheaper XUNIUZERO?
Honestly, I don’t think so. The XUNIUZERO costs less per battery, has a higher 150 mAh capacity versus BEVIGOR’s 130 mAh, and includes a 7-year shelf life that BEVIGOR doesn’t mention. The only reason to pick BEVIGOR is if you specifically want a 10-pack instead of 12 and trust a brand with over 1,000 ratings instead of just 63.
Which battery is safest for kids β Granicell or XUNIUZERO?
Both the Granicell and XUNIUZERO include child-resistant packaging and a non-toxic bitter coating to discourage swallowing, so they’re equally safe on paper. I give a slight edge to the Granicell because the listing explicitly says the packaging is “nearly impossible to open without scissors,” which is exactly what I want to hear as a parent. The BEVIGOR doesn’t mention any child safety features at all, so I’d skip it if kids are in the house.
Can I use any of these CR2025 batteries in my Apple AirTag?
Yes, all three are specifically designed to be compatible with Apple AirTags. The Granicell and BEVIGOR listings even say “Compatible with Apple AirTag” right in the product name. Just make sure you’re using a CR2025 and not a CR2032 β the AirTag takes the thinner CR2025 size, and the Granicell listing actually notes it requires 6 CR2032 batteries separately, so don’t get those mixed up.
Is the XUNIUZERO with 63 ratings as reliable as the Granicell with 2,651 ratings?
That’s the big question, and I’ll be straight with you β the Granicell is the safer bet simply because thousands of buyers have already tested it. The XUNIUZERO has a slightly higher 4.6-star average compared to Granicell’s 4.4 stars, but that’s based on only 63 reviews. I’d go with the Granicell if you want proven reliability, and the XUNIUZERO if you’re willing to save money and gamble on a newer brand.
Which 20-pack offers the best value for AirTag users?
The Granicell is the only one here that comes in a 20-pack, and it’s a great deal at that size. With 150 mAh per battery and child-safe features, you’re getting top-tier performance at a low per-battery cost. The XUNIUZERO 12-pack is the best budget option if you don’t need that many, but for bulk buyers, the Granicell 20-pack is the clear winner.
My Final Verdict
The Granicell 2025 is my overall winner β it delivers the full 150 mAh capacity, includes the best child safety features with bitter coating and secure packaging, and has over 2,600 ratings proving its reliability. The XUNIUZERO is the runner-up for budget shoppers who still want that same 150 mAh capacity plus a 7-year shelf life, while the BEVIGOR lags behind with only 130 mAh and no child safety features.
If you’re still on the fence, ask yourself this: do you want the most proven battery with the best safety features, or are you willing to try a newer brand to save money? The Granicell gives you peace of mind that’s worth every penny.
