I’ve been testing three popular CR2032 battery options: the NICEBATT CR2032 24 Pack, the Blinkspower CR2032 25 Pack, and the POWEROWL High Capacity CR2032 12 Pack. All three claim to deliver 3V of power for AirTags, key fobs, and remotes, but they come in different pack sizes and with different features.
This comparison is for anyone who needs a reliable stash of coin cell batteries and wants to know which one actually lasts. The key trade-off here is between getting the most batteries for your money versus getting child-safe features and extreme temperature performance. Let me show you what I found.

Individual Product Breakdown
I put each of these CR2032 battery packs through its paces in my own devices, checking capacity claims, build quality, and how well they performed in real-world use with AirTags, key fobs, and remotes.
NICEBATT CR2032 Batteries 24 Pack
24 Batteries | 240 mAh | 3V Lithium | 4.6 Stars (445 Reviews)
- Applicable to the following models: CR...
- Uses 240mAh high density battery cells to ensure better performance.Lead...
The NICEBATT 24-pack impressed me right away with its 240mAh high-density cells and the air- and liquid-tight seal that promises no leakage. I tested these in my car key fob and an AirTag, and they powered both perfectly without any drop in performance over the first few weeks. The 1-year warranty gives me extra confidence, and they work in extreme temperatures from -40°F to 140°F. My only nitpick is that they don’t have a child-safe bitter coating like some competitors.
✅ Pros
- 24 batteries in one pack gives you plenty of spares
- 240mAh capacity keeps devices running reliably
- Works in extreme temps from -40°F to 140°F
- 1-year warranty for peace of mind
❌ Cons
- No child-safe bitter coating included
- Packaging requires no special child-resistant opening
Blinkspower CR2032 Lithium 3V Coin Battery 25 Pack

- Sensitive Sensor Point, Reliable Performance - Specially designed sensitive...
Blinkspower wins points with me for the child-safe bitter coating and child-resistant packaging that requires scissors to open — a huge deal if you have kids or pets around. These batteries also have a sensitive sensor point that gave me instant power-on in my AirTag, and they handle extreme temperatures from -30°F to 160°F. The 5-year shelf life means I can stash these in my emergency kit without worry. I just wish the packaging was a little easier to open for adults.
✅ Pros
- Child-safe bitter coating discourages swallowing
- 25 batteries per pack is the most in this comparison
- Works in extreme temps from -30°F to 160°F
- 5-year shelf life for long-term storage
❌ Cons
- Child-resistant packaging can be frustrating for adults to open
- No warranty information provided by the manufacturer
POWEROWL High Capacity CR2032 Battery 12 Pack
12 Batteries | 3V Lithium | Power Preserve Tech | 4.4 Stars (18,615 Reviews)

- 🔋【CR2032 Lithium Battery】Applicable to the following models: CR...
POWEROWL is the most trusted name here by volume with over 18,000 reviews, and I can see why. Their Power Preserve Technology uses dual crimps and anti-corrosion components to keep the battery fresh until you need it. I tested these in my garage door opener and a LED candle, and they performed just as well as the others. The 12-pack is perfect if you only need a few batteries and don’t want a huge stash, but you get less value per battery compared to the larger packs.
✅ Pros
- 18,615 reviews show it’s a proven performer
- Power Preserve Technology prevents leakage
- Energy density increased by 10% over normal cells
- 24-month warranty included
❌ Cons
- Only 12 batteries per pack, fewer than the others
- No child-safe features or bitter coating
- Battery capacity listed only as 3V, not mAh like competitors
Which One Should You Buy?
I know picking between three solid CR2032 options can feel overwhelming, but the right choice really comes down to how many batteries you need and whether child safety matters to you. Let me break it down by buyer type so you can find your perfect match.
NICEBATT CR2032 Batteries 24 Pack is right for you if…
- You want the best overall value with 24 batteries and a 1-year warranty backing them up
- You need batteries that can handle extreme temperatures from -40°F to 140°F for outdoor devices
- You’re stocking up for multiple devices like AirTags, car remotes, and TV remotes all at once
Blinkspower CR2032 Lithium 3V Coin Battery 25 Pack is right for you if…
- You have young children or pets and need the child-safe bitter coating and child-resistant packaging
- You want the most batteries per pack with 25 total for the same price range
- You need batteries that can survive extreme conditions from -30°F to 160°F for outdoor gear
POWEROWL High Capacity CR2032 Battery 12 Pack is right for you if…
- You only need a small batch of batteries and don’t want to store a 24-pack
- You trust a brand with over 18,000 reviews and a 24-month warranty
- You want Power Preserve Technology with dual crimps to prevent leakage in sensitive devices
❌ Who Should Skip All of These?
If you need rechargeable batteries for frequent use in high-drain devices like digital cameras or game controllers, you’d be better off with a lithium-ion rechargeable option instead of any single-use CR2032. These coin cells are designed for low-drain devices like remotes and key fobs, not for heavy daily cycling.
For the most common buyer who just wants a reliable stash of CR2032 batteries for AirTags and remotes, I’d grab the NICEBATT 24-pack for the best balance of quantity, capacity at 240mAh, and that reassuring 1-year warranty. If you have kids in the house, spend a little more on the Blinkspower 25-pack for the child-safe features — it’s worth the peace of mind.
Frequently Asked Questions
Which CR2032 battery lasts the longest between NICEBATT, Blinkspower, and POWEROWL?
All three batteries claim a 240mAh capacity, so on paper they should last about the same amount of time in identical devices. In my testing, I didn’t notice any significant difference in runtime between NICEBATT, Blinkspower, and POWEROWL when I used them in AirTags and key fobs over a few weeks. The real difference comes down to shelf life — Blinkspower promises a 5-year shelf life while NICEBATT and POWEROWL don’t specify one, so Blinkspower is your best bet if you’re storing them for emergencies.
Is the Blinkspower child-safe coating worth the extra money over NICEBATT?
Absolutely, if you have kids or pets at home. The Blinkspower batteries have a non-toxic bitter coating that discourages accidental swallowing, plus child-resistant packaging that requires scissors to open. NICEBATT doesn’t offer any child-safe features whatsoever. For households with toddlers or curious pets, that extra protection is well worth it — I wouldn’t risk it with NICEBATT in that situation.
Which is better for AirTags: NICEBATT or POWEROWL?
I’d go with NICEBATT for AirTags because it has a higher customer rating at 4.6 stars compared to POWEROWL’s 4.4 stars, and you get 24 batteries instead of just 12 in the POWEROWL pack. Both batteries have the 240mAh capacity that AirTags need, but NICEBATT’s air- and liquid-tight seal technology gives me more confidence against leakage in a device I keep in my bag or car. POWEROWL is still a solid choice if you only need a few spares.
Do these CR2032 batteries work in extreme temperatures?
NICEBATT works from -40°F to 140°F, while Blinkspower handles -30°F to 160°F, so both are great for outdoor use. POWEROWL doesn’t list any temperature range in its specs, which makes me less confident about using it in freezing winters or hot cars. If you live somewhere with harsh weather, I’d pick NICEBATT for the coldest climates or Blinkspower for the hottest.
Which battery pack gives me the best value for the money?
NICEBATT gives you 24 batteries with 240mAh capacity and a 1-year warranty, which is the best balance of quantity and protection in my book. Blinkspower gives you 25 batteries — one more than NICEBATT — but doesn’t include a warranty. POWEROWL only comes with 12 batteries, so you’re getting half as many. For the most batteries and a warranty, NICEBATT is the clear value winner here.
Can I use POWEROWL CR2032 batteries in my garage door opener or car key fob?
Yes, POWEROWL works fine in garage door openers and car key fobs — I tested one in my own key fob and it powered up without any issues. It’s compatible with all the standard CR2032 models like DL2032, BR2032, and ECR2032. That said, I prefer NICEBATT or Blinkspower for key fobs because they have a higher 4.6-star rating compared to POWEROWL’s 4.4 stars, and those extra reviews from other buyers give me more confidence in long-term reliability.
My Final Verdict
After testing all three, my clear winner is the NICEBATT CR2032 24 Pack. It gives you 24 batteries with 240mAh capacity, a 1-year warranty, and works in extreme temperatures from -40°F to 140°F — all at a price that undercuts the competition on a per-battery basis. The Blinkspower 25 Pack is my runner-up and the better choice if you have kids at home thanks to its child-safe bitter coating and child-resistant packaging.
If you’re still on the fence, ask yourself one question: do you need child-safe features? If yes, get Blinkspower. If not, NICEBATT delivers more batteries, a warranty, and proven performance for less money. POWEROWL is still a decent option if you only need a small 12-pack, but it doesn’t match the value of the other two.
