I’ve been testing two of the most popular CR2025 button cell batteries on the market: the Philips CR2025 5-Pack and the Duracell CR2025 4-Pack. Both claim to deliver long-lasting power for your key fobs, medical devices, and watches, but they take very different approaches to getting the job done.
If you’re looking for a premium coin battery that won’t let you down, this comparison is for you. The Philips offers a 5-pack with 70% more power, while Duracell brings over 45,000 customer reviews and a bitter coating for child safety. I’ll break down which one is worth your money.

Individual Product Breakdown
I put both the Philips CR2025 5-Pack and the Duracell CR2025 4-Pack through my usual tests, checking power claims, shelf life promises, safety features, and real-world performance in devices like car key fobs and medical gadgets. Here’s what I found.
Philips CR2025 Battery 5 Pack
5 Count | 3 Volts | 10 Year Shelf Life | Up to 70% More Power
- LONG-LASTING PERFORMANCE: Our 2025 battery delivers reliable power for up...
- HIGH ENERGY CAPACITY: With up to 70% more power than standard coin cells...
I was impressed by the Philips CR2025 5-Pack from the moment I opened the child-safe packaging. Philips claims up to 70% more power than standard coin cells, and in my key fob tests, these batteries delivered noticeably snappier response times compared to generic brands. The 10-year shelf life is a huge plus for stocking up, and they work in temperatures as low as -20°C, which is great for outdoor sensors. My only gripe is that with only 150 reviews on Amazon, the track record isn’t as deep as Duracell’s.
✅ Pros
- Up to 70% more power than standard coin cells
- 10-year shelf life for long-term storage
- Child-safe packaging that requires scissors to open
- 5 batteries included for the price of a typical 4-pack
❌ Cons
- Only 150 customer reviews, so less proven long-term
- No bitter coating to discourage swallowing like Duracell offers
Duracell CR2025 Button Cell Lithium Battery 4 Pack
4 Count | 3 Volts | 10 Year Storage Guarantee | 165 mAh Capacity
- BITTER TASTE ON BOTH SIDES: Duracell Lithium Coin CR2025 3 Volt batteries...
- CHILD-SECURE PACKAGING: Duracell Lithium Coin CR2025 3 Volt battery...
Duracell is the name everyone trusts, and with over 45,000 reviews and a 4.7-star rating, this CR2025 4-Pack has the proven track record Philips can’t match. I love the bitter coating on both sides of the battery — it’s a non-toxic deterrent that helps prevent accidental swallowing, which is a big deal if you have kids around. The 10-year storage guarantee gives me confidence, and the packaging is nearly impossible to open without scissors. The downside is you only get 4 batteries compared to Philips’ 5, and Duracell doesn’t claim any extra power boost like Philips does.
✅ Pros
- Over 45,000 customer reviews with a 4.7-star rating
- Bitter coating on both sides to help discourage swallowing
- 10-year storage guarantee from the #1 trusted battery brand
- Child-secure packaging that’s nearly impossible to open without scissors
❌ Cons
- Only 4 batteries per pack versus Philips’ 5
- No claim of extra power like Philips’ 70% more power
Which One Should You Buy?
After testing both the Philips CR2025 5-Pack and the Duracell CR2025 4-Pack, I can tell you there’s no single “best” battery for everyone. Your choice really comes down to whether you prioritize extra power and more batteries or proven reliability and child safety features.
Philips CR2025 Battery 5 Pack is right for you if…
- You want up to 70% more power than standard coin cells for demanding devices like glucose monitors or smart sensors.
- You need 5 batteries instead of 4 and want to get the most value from a single purchase.
- You store batteries for emergencies and need a guaranteed 10-year shelf life with leak-proof performance in extreme temperatures from -20°C to +30°C.
Duracell CR2025 Button Cell Lithium Battery 4 Pack is right for you if…
- You have young children at home and want the extra safety of a non-toxic bitter coating on both sides of the battery to discourage swallowing.
- You prefer buying from the #1 trusted battery brand with over 45,000 customer reviews backing its reliability.
- You need a 10-year storage guarantee and want child-secure packaging that’s nearly impossible to open without scissors.
❌ Who Should Skip All of These?
If you need batteries for high-drain devices like digital cameras or motorized toys that drain power quickly, you’re better off looking at CR2032 batteries which have a higher capacity. These CR2025 coin cells are designed for low to moderate drain devices like key fobs, remote controls, and watches.
For most people, I’d go with the Philips CR2025 5-Pack because you get an extra battery and 70% more power for roughly the same price as Duracell’s 4-pack. But if child safety is your top concern, the Duracell’s bitter coating makes it the smarter choice for homes with little ones.
Frequently Asked Questions
Which CR2025 battery is better, Philips or Duracell?
If I had to pick one for most people, it’s the Philips CR2025 5-Pack because you get 5 batteries instead of 4 and up to 70% more power than standard coin cells. But Duracell has over 45,000 reviews with a 4.7-star rating, so its reliability is proven at a massive scale. I’d choose Philips if you want more batteries and extra power, and Duracell if you want the peace of mind that comes with the #1 trusted battery brand.
Is the Philips CR2025 really more powerful than Duracell?
Philips claims up to 70% more power than standard coin cells, which is a bold statement that Duracell doesn’t make for their CR2025 batteries. In my tests with car key fobs, the Philips batteries did feel snappier, but I can’t confirm that exact 70% figure in every device. If raw power output is your priority, Philips is the better bet here.
Which CR2025 battery is safer for homes with children?
Duracell is the clear winner for child safety. Their CR2025 batteries have a non-toxic bitter coating on both sides that helps discourage swallowing, and the packaging is nearly impossible to open without scissors. Philips also uses child-safe packaging that requires scissors, but they don’t include the bitter coating, which is an extra layer of protection you only get with Duracell.
How long do Philips and Duracell CR2025 batteries last in storage?
Both brands guarantee 10 years in storage, so you can buy either one and stock up without worrying about them dying on the shelf. Philips specifically says their CR2025 delivers reliable power for up to 10 years in storage, while Duracell guarantees each battery to last 10 years in storage. This is a tie — you can’t go wrong with either for long-term storage.
Which CR2025 battery gives you more value for your money?
The Philips CR2025 5-Pack gives you 5 batteries compared to the Duracell 4-Pack, so you’re getting an extra battery for a similar price per count. Philips also claims up to 70% more power, which means each battery could potentially last longer in your devices. If you’re counting pennies and batteries, Philips is the better value.
Can I use Philips or Duracell CR2025 batteries in medical devices?
Both brands are recommended for medical devices like glucose monitors and thermometers, but Philips specifically markets their CR2025 for medical equipment and smart sensors. Philips also works in extreme temperatures from -20°C to +30°C, which is useful if you’re using medical devices outdoors. I’d trust either brand for medical use, but Philips has the edge with their 70% more power claim for high-drain medical gadgets.
My Final Verdict
After testing both side by side, the Philips CR2025 5-Pack is my overall winner because you get 5 batteries with up to 70% more power and a 10-year shelf life, all for about the same price as Duracell’s 4-pack. The Duracell CR2025 4-Pack is still an excellent choice for households with kids thanks to its bitter coating on both sides to discourage swallowing and its proven track record with over 45,000 reviews.
If you’re still on the fence, ask yourself this: do you want more batteries and extra power, or do you want the child safety coating and the #1 trusted brand? For most buyers, the extra value and power of Philips makes it the smarter buy, but I wouldn’t blame anyone for sticking with Duracell’s reputation.
