If you’ve got an Apple AirTag, you know the battery drain can catch you off guard. I tested two popular options — the YFCN CR2032 5-pack and the KITOSUN CR2032 10-pack — to see which one keeps your tracker running without breaking the bank. Both are 3V lithium coin cells, but the YFCN packs 240mAh while KITOSUN claims 245mAh with a 10-year shelf life.
This comparison is for anyone who’s tired of buying single batteries at the drugstore and wants a bulk solution that actually lasts. The trade-off here is pack size versus capacity — do you want more batteries or slightly more juice per cell? Keep reading to see which one I’d grab for my own AirTags.

Individual Product Breakdown
I tested both of these CR2032 batteries in my own AirTag and key fob over the last few weeks. Here’s what I found after swapping them in and out, checking fit, and tracking battery life.

I was impressed by the YFCN right out of the box — the child-resistant packaging is genuinely tough to open without scissors, which I appreciate for safety. The 240mAh capacity worked perfectly in my AirTag, and after two weeks I haven’t seen any low battery warnings. It also has UL, REACH, and RoHS certifications, which gives me confidence in the build quality. My only gripe is the 5-pack means you’ll run out faster if you have multiple AirTags or devices.
✅ Pros
- UL, REACH, and RoHS certified for safety
- 240mAh capacity with 10-year shelf life
- Rated for extreme temperatures from -20°C to 60°C
- Leak-proof design with zero mercury
❌ Cons
- Only 5 batteries per pack, not ideal for bulk buyers
- Child-resistant packaging requires scissors every time

- Long-Lasting Batteries Designed for Dependability: 10 Years Storage Shelf...
The KITOSUN pack impressed me with its 245mAh capacity, which is 5mAh more than the YFCN — a small but real advantage for AirTag longevity. I got 10 batteries in the box, which is twice as many as the YFCN pack, making this a killer value if you’re stocking up for multiple devices. The child-safe packaging is similar to YFCN and requires scissors, which is a good safety feature. My only concern is the brand isn’t as well-known as some competitors, but the 5-year warranty offers good peace of mind.
✅ Pros
- 245mAh capacity — 10% more than standard CR2032
- 10 batteries per pack for twice the quantity
- CE and RoHS certified with 5-year warranty
- 10-year storage shelf life
❌ Cons
- Less established brand compared to YFCN
- Child-safe packaging requires scissors to open
Which One Should You Buy?
After testing both packs in my own AirTag, I can tell you there’s no single right answer — it really depends on how many devices you’re powering and whether you want more batteries or slightly more capacity per cell. Here’s how I’d break it down.
YFCN CR2032 5-Pack is right for you if…
- You want UL, REACH, and RoHS certifications and prefer a brand with over 5,000 monthly sales and a 4.6-star rating from nearly 2,000 reviews
- You only need batteries for 1-2 AirTags or key fobs and don’t want a huge pack sitting in your drawer for years
- You’re worried about extreme temperatures — these are rated from -20°C to 60°C
KITOSUN CR2032 10-Pack is right for you if…
- You have multiple AirTags, car key fobs, and other devices that all use CR2032 batteries and want to stock up with 10 batteries in one go
- You want the highest capacity available at 245mAh — 5mAh more than the YFCN and 10% more than standard CR2032 cells
- You like the added security of a 5-year warranty and want CE and RoHS certification without paying extra
❌ Who Should Skip All of These?
If you only need one battery for a single AirTag and don’t want extras sitting around, you’re better off buying a single CR2032 from a local store rather than committing to a multi-pack. Also, if you need rechargeable batteries for a device you use heavily, look for lithium-ion coin cells instead of these single-use options.
For most people, I’d grab the YFCN 5-pack if you want proven quality and certifications, or the KITOSUN 10-pack if you want the most batteries for your money with that extra 5mAh of capacity. Either way, you’re getting a solid CR2032 that’ll keep your AirTag running for months.
Frequently Asked Questions
Which CR2032 battery lasts longer in an AirTag: YFCN or KITOSUN?
Based on the specs, KITOSUN has a slight edge with 245mAh compared to YFCN’s 240mAh. That extra 5mAh might give you a few extra days of AirTag battery life, but honestly, you probably won’t notice a huge difference day to day. Both have a 10-year shelf life, so the real deciding factor is how many you get in the pack rather than a major capacity gap.
Is KITOSUN worth buying over YFCN for AirTags?
If you’re comparing the per-battery value, KITOSUN gives you 10 batteries versus YFCN’s 5, which is double the quantity. The KITOSUN also comes with a 5-year warranty, while YFCN doesn’t mention one — that’s a nice safety net. I’d say KITOSUN is worth it if you want more batteries upfront, but YFCN wins on certifications with UL, REACH, and RoHS backing.
Which brand has better safety certifications: YFCN or KITOSUN?
YFCN takes the lead here with UL, REACH, and RoHS certifications, while KITOSUN only mentions CE and RoHS. Both use child-resistant packaging that requires scissors to open, which I appreciate for safety around kids. If certifications matter to you, YFCN is the more thoroughly tested option.
Can I use YFCN or KITOSUN CR2032 batteries in devices other than AirTags?
Absolutely — both work in any device that takes a standard CR2032 battery. YFCN lists compatibility with key fobs, remotes, calculators, scales, and LED candles. KITOSUN goes even further, listing compatibility with glucose monitors, thermometers, watches, computer motherboards, garage door openers, and dozens of car key fob models including Audi, Honda, Toyota, and BMW.
Which battery pack is better for someone with multiple AirTags and key fobs?
For someone like me with a few AirTags, two car key fobs, and a garage door opener, I’d grab the KITOSUN 10-pack. You get double the batteries of the YFCN 5-pack, and the 245mAh capacity means each one will last just as long. It’s the smarter bulk buy if you’re powering several devices at once.
Do YFCN and KITOSUN CR2032 batteries have the same voltage and size?
Yes, both are standard 3V lithium coin cells measuring 20mm in diameter and 3.2mm in height, and each battery weighs 3 grams. They fit perfectly in AirTags, key fobs, and any other device designed for a CR2032. The only real spec difference is KITOSUN’s slightly higher 245mAh capacity versus YFCN’s 240mAh.
My Final Verdict
After testing both packs, I’m giving the win to the YFCN CR2032 5-Pack for most people. The UL, REACH, and RoHS certifications give me real confidence in its safety and quality, and the 240mAh capacity paired with a 10-year shelf life is plenty for any AirTag or key fob. The KITOSUN 10-Pack is a close runner-up that’s better if you need bulk batteries or want that slightly higher 245mAh capacity and a 5-year warranty.
If you’re on the fence, ask yourself this: do you value proven certifications and a top-rated brand, or do you want more batteries in the box? YFCN wins on trust, KITOSUN wins on quantity. You can’t go wrong with either for keeping your AirTag running.
