A budget-friendly coin cell starts with the right code. CR2025 and CR2032 cells share a 20 mm diameter but differ in thickness, so the code your device asks for matters more than the logo on the pack.
I compared five brands using manufacturer pages and retailer listings, not hands-on tests.
Each pick earns its spot for something specific: clear model labelling, child-safety features, accessory compatibility, pack size, or written warranty terms.
Key Takeaways
- Our top pick lists exact dimensions and equivalent labels for both codes.
- Energizer’s Ultimate Child Shield packs add Color Alert and a bitter coating.
- Duracell’s bitter-coated 2032 is the cell Apple names for AirTag.
- Panasonic’s ten-pack suits homes with several CR2032 devices.
- Maxell backs its coin cells with a written 90-day defect warranty.
How we picked
I looked at model identification, useful pack sizes, packaging safety features and how easy each brand makes it to confirm the right cell.
Prices and ratings are page snapshots checked on October 19, 2026. They are not permanent offers or lab results.
Always match the code your device manufacturer specifies.
CR2025 and CR2032 differ in thickness, so never shim, stack, force or recharge disposable coin cells. Shelf-life claims describe storage, not runtime once installed.
Child-resistant packaging and bitter coatings don’t make a cell safe to swallow. Keep new and used batteries away from children.
If you suspect a child has swallowed one, get expert help right away. In the US, the 24-hour National Battery Ingestion Hotline is 1-800-498-8666.
1. GP Batteries
Pros
- Separate pages list both codes as 3V lithium, at 20 × 2.5 mm and 20 × 3.2 mm.
- Equivalent labels are shown: DL2025 and 2025, DL2032 and 2032.
- Childproof packaging that opens only with scissors.
Cons
- Listings are priced in Hong Kong dollars.
- Product pages don’t state the cell count per pack.
Why we picked it
GP Batteries makes the code check simple. Its Hong Kong store lists CR2025 CR2032 cells side by side, each with exact dimensions and equivalent labels, so you can compare the two thicknesses before buying.
The manufacturer also claims up to 10 years of shelf life and an operating range of -20°C to +60°C.
Pricing
Both the CR2025 and CR2032 listings showed HKD 14.00 on October 19, 2026. Confirm pack quantity and delivery to your region at checkout.
2. Energizer
Pros
- Ultimate Child Shield cells add Color Alert, a bitter coating and child-resistant packaging.
- Color Alert dyes the mouth blue seconds after contact with saliva.
- Rated from -22°F to 140°F.
Cons
- Child Shield features appear only on select packs.
- The retailer rating mixes in reviews from other pack sizes.
Why we picked it
Energizer is the strongest pick here for safety features. Its Ultimate Child Shield range pairs Color Alert with Ingestion Burn Protection and a bitter coating, which gives caregivers an extra warning sign.
Packaging varies by listing, so check the pack front for the Child Shield name.
Pricing
Home Depot’s CR2032 two-pack, model 2032BP-2N, showed USD 6.87 (USD 3.44 per cell) and 4.7/5 from 5,418 reviews.
3. Duracell
Pros
- Non-toxic bitter coating on both sides of the CR2032 cell.
- Child-secure packaging that’s nearly impossible to open without scissors.
- Guaranteed for 10 years in storage.
Cons
- Packaging needs scissors every time.
- Not every coated cell suits every device, so check the pack wording.
Why we picked it
Duracell is the easy choice for AirTag owners. Apple’s own battery guide names the Duracell 2032 with Bitter Coating and tells buyers to look for packs marked “Compatible with Apple AirTag.” Apple also notes some coated CR2032 cells may not work, so the pack label matters.
Pricing
H-E-B’s CR2032 two-pack showed USD 7.26 (USD 3.63 per cell). In-store and delivery prices may vary.
4. Panasoni
Pros
- Ten cells per pack for multi-device homes.
- Child-resistant, tear-resistant packaging.
- Rated from -22°F to 140°F.
Cons
- Panasonic confirms these cells have no bitter coating.
- Shelf life is listed at up to 8 years, shorter than others here.
Why we picked it
Panasonic suits homes with several CR2032 devices, like key fobs, scales and remotes.
The ten-pack (model PCR2032P/10W) brings the per-cell cost well below any two-pack in this list.
Count your devices first, since a bulk pack only saves money if you use the cells. A practical frugal living guide can help you spot where small household purchases add up.
Pricing
Home Depot’s ten-pack showed USD 6.49 (USD 0.65 per cell) and 4.6/5 from 60 reviews.
5. Maxell
Pros
- US product page lists both CR2025 and CR2032.
- Designed for stable voltage under long-term low load.
- Written 90-day defect warranty.
Cons
- Warranty excludes normal wear, misuse and commercial use.
- No bitter coating or child-shield features are listed.
Why we picked it
Maxell earns its place with clear product codes and written warranty terms.
The brand positions its coin cells for memory and clock backup, where steady low-drain power matters. Its warranty covers defects for 90 days from purchase, though it doesn’t promise a set battery life.
Pricing
Maxell USA doesn’t list prices, and the US listings I found came from third-party marketplace sellers. Compare cell count and the delivered total before buying.
Conclusion
The best budget coin cell is the one that matches your device’s code.
Our top pick makes that check easy, with exact dimensions and equivalent labels for both sizes.
For homes with young children, Energizer’s Child Shield packs add the most safety features.
AirTag owners should look for Duracell’s compatibility label, and multi-device homes will get the most from Panasonic’s ten-pack.
Whichever brand you choose, confirm the code, pack count and final price before paying.
FAQ
Can I use a CR2025 instead of a CR2032?
Both are 3V and 20 mm wide, but a CR2025 is 2.5 mm thick and a CR2032 is 3.2 mm.
Use the code your device specifies, and never shim or stack cells to make one fit.
Do bitter-coated batteries work in an AirTag?
Apple recommends a bitterant-coated CR2032, such as Duracell’s, in packaging marked “Compatible with Apple AirTag.” Apple also notes that some coated cells might not work, so check the pack label.
How long do CR2032 batteries last in storage?
It depends on the brand. Manufacturer claims in this list range from up to 8 years to 10 years. These figures describe storage, not how long a cell lasts once installed.
What should I do if a child swallows a coin battery?
Get help immediately. In the US, call the 24-hour National Battery Ingestion Hotline at 1-800-498-8666, and have the battery’s ID number from the package ready if you can.
