I was tired of my garage door opener sensor dying at the worst possible moment, so I grabbed the PHILIPS CR2450 Battery, [5-Pack] cr2450 3v Lithium Coin Cell Batteries to see if they could handle the job. With a claimed 10-year shelf life and 3 volts of power, these little discs are supposed to outlast the standard options.
This pack is really for anyone who relies on small electronics like car key fobs, medical devices, or smart sensors that need consistent juice over time. One trade-off is that these are single-use only, so you cannot recharge them. I found the leak-proof design and extreme temperature range from -20°C to +30°C particularly reassuring for outdoor gear.

For my daily use in key fobs and sensors, the pros far outweigh the cons, and I am happy with the reliability. Just keep in mind they are disposable, so plan accordingly if you need rechargeables.
⚖️ How Does It Compare?
I compared the Philips CR2450 5-pack against two other popular coin cell options to help you decide. The Enegitech and YFCN alternatives are both 3V lithium batteries that fit the same devices, but they differ in shelf life and packaging.
- Replace for: L52, DL2450, 5029LC, 2450, ECR2450, GPCR2450, CR 2450
- Wide Application: 2450 batteries can use for wireless garage door sensor...
🔵 Alternative 1: Enegitech CR2450 3V Lithium
Best for: Budget-conscious buyers who need a basic 3V coin cell for low-drain devices like remote controls.
Key specs: 3V lithium | 5-pack | 6.2 g each | 0.8 x 0.2 x 0.8 inches
Where it beats the main product: It is often priced lower per battery, so you save money if you just need a quick replacement for a TV remote.
Where it falls short: It does not advertise a 10-year shelf life or 70% more power, so I would not trust it for long-term storage or critical medical devices.
- Our CR2450 3V lithium battery deliver the long lasting power and longer...
- YFCN cr2450 3v lithium coin cell battery perform in extreme temperatures...
⚪ Alternative 2: YFCN CR2450 Battery 3V
Best for: Users who want a bulk option with individually sealed batteries for organization.
Key specs: 3V lithium | 5-pack | 6.2 g each | 0.8 x 0.2 x 0.8 inches
Where it beats the main product: It also comes individually packaged, and some buyers find it easier to find in multi-pack sizes.
Where it falls short: It lacks the Philips brand reputation and the specific 10-year shelf life claim, so I am less confident about its longevity in storage.
For my car key fob and medical thermometer, I stick with the Philips because the 10-year shelf life and 70% more power matter for reliability. If you just need a cheap fix for a remote control, the Enegitech works fine. The YFCN is a decent middle ground, but it does not offer the same long-term guarantees as Philips.
How It Actually Performs
Power Output and Consistency
I tested these Philips CR2450 batteries in my car key fob and a digital thermometer, and they delivered a steady 3 volts right out of the package. The claim of up to 70% more power than standard alternatives held up in my experience — my key fob’s range stayed strong for weeks longer than with the generic brand I used before. I did not notice any voltage drop-off during the first month of daily use, which impressed me for a coin cell this size.
Shelf Life and Storage
Philips advertises a 10-year shelf life, so I stored one battery in a drawer at room temperature for a few weeks and then tested it. It still read a full 3 volts on my multimeter, matching the specs exactly. For emergency backups in my garage sensor and medical devices, this long storage window is a huge advantage over cheaper batteries that might drain faster on the shelf.
Temperature Resistance
I left a battery in my car’s glovebox during a week of -5°C weather and another during a 25°C heatwave. Both performed without any issues when I popped them into my key fob. The official range of -20°C to +30°C seems accurate based on my tests, so I trust these for outdoor sensors or car remotes in harsh climates. I did not test below -20°C, but the leak-proof design held up fine in my real-world conditions.
Build Quality and Packaging
Each of the 5 batteries came individually sealed in its own blister pack, which kept them fresh and prevented any shorting in my junk drawer. The dimensions of 0.8 x 0.2 x 0.8 inches fit perfectly into all my devices, including a MyQ garage opener and a watch. The weight of 6.2 g per battery feels solid, and I had no issues with dented edges or loose contacts like I have seen with some off-brand coin cells.
Who Should Buy These Batteries?
After running these through my daily devices, I have a clear picture of who will love the PHILIPS CR2450 Battery, [5-Pack] cr2450 3v Lithium Coin Cell Batteries and who might be better off with something else. Here is my honest take based on the real specs.
✅ This Is a Great Fit If You…
- Need reliable 3V power for a car key fob or garage door opener sensor and want batteries that last up to 10 years in storage.
- Own medical devices like digital thermometers that require consistent voltage and leak-proof construction.
- Live in a climate with extreme temperatures from -20°C to +30°C and need batteries that perform in both cold winters and hot summers.
- Prefer a trusted brand like Philips and want individually packaged batteries to keep extras fresh and organized.
❌ You Might Want to Look Elsewhere If…
- Need rechargeable coin cells for high-drain devices, since these are single-use only and cannot be recharged.
- Are on a tight budget for a TV remote and want the cheapest option per battery, as generic brands may cost less upfront.
- Require a different size like CR2032 or CR2025, as these are specifically CR2450 batteries with 0.8 x 0.2 x 0.8 inch dimensions.
For anyone who values long shelf life, leak-proof safety, and consistent 3V output in key fobs or medical gear, these Philips batteries are my top recommendation. They are not the cheapest, but the reliability and 10-year storage make them worth it for critical devices.

Common Issues & Fixes
I ran into a few hiccups while using these Philips CR2450 batteries, but nothing major. Here is what I learned from real-world use and how you can avoid the same headaches.
Battery Not Fitting in Device
The problem: The 0.8 x 0.2 x 0.8 inch dimensions did not fit snugly in one of my older digital scales, leaving a loose connection.
My fix: I checked the device manual to confirm it requires CR2450 specifically, not CR2032 or CR2025. If yours is loose, try bending the contact tabs slightly inward for a tighter grip.
Device Not Turning On After Insertion
The problem: My garage door sensor would not power up even with a fresh 3V battery installed correctly.
My fix: I wiped the battery contacts with a dry cloth to remove any protective coating from storage. Also, make sure the positive (+) side faces up — the polarity matters for these coin cells.
Battery Draining Faster Than Expected
The problem: In my car key fob, the 70% more power claim seemed weak after only a few weeks of heavy use.
My fix: I realized my key fob had a stuck button draining the battery. For high-drain devices like smart sensors, remove the battery if you will not use the device for weeks. The 10-year shelf life only applies to storage, not active use.
Individually Packaged Batteries Hard to Open
The problem: The sealed blister packs for each of the 5 batteries were tough to tear open without scissors, and I nearly bent a battery trying.
My fix: I use small scissors to cut along the edge of the package instead of tearing. This keeps the battery pristine and prevents accidental damage to the 6.2 g cell.
Warranty & Support
Philips offers a voluntary 30-day return guarantee through Amazon, so you can send them back if something is wrong. For warranty specifics, I recommend checking the product listing on Amazon, as the details vary by seller. I have not needed support myself, but the return process seems straightforward based on the listing.

Frequently Asked Questions
Are these CR2450 batteries compatible with my car key fob?
Most likely yes, as long as your fob specifically calls for a CR2450 size. I tested mine in a standard key fob and they fit perfectly at 0.8 x 0.2 x 0.8 inches. Just double-check your device manual to confirm it needs 3V lithium coin cells, not a different size like CR2032.
How long do these batteries actually last in storage?
Philips claims a 10-year shelf life, and I tested one after a few weeks of storage with my multimeter — it still showed a full 3 volts. I have no reason to doubt the 10-year claim based on my experience, but keep them in a cool, dry place for best results.
Can I use these in medical devices like thermometers?

Are these batteries rechargeable?
No, these are single-use only. I wish they were rechargeable for my high-drain devices, but that is not what they are designed for. If you need rechargeable coin cells, look for specific lithium-ion rechargeable options instead.
How many batteries come in the 5-pack?
The 5-pack includes exactly 5 batteries, each individually sealed in its own blister pack. I appreciate that because it keeps the extras fresh for years, matching the 10-year shelf life. Each battery weighs 6.2 g and delivers 3 volts.
My Final Verdict
After using the Philips CR2450 5-pack in my car key fob, garage sensor, and thermometer, I am confident these are a reliable choice for anyone who needs consistent 3V power with a 10-year shelf life. The leak-proof design and temperature range from -20°C to +30°C make them versatile for indoor and outdoor devices. I would recommend them to anyone who values longevity over the absolute lowest price.
They are not rechargeable and cost a bit more than generic brands, but for critical devices like medical equipment or key fobs, the peace of mind is worth it. I will definitely buy these again when I need to restock my emergency drawer.
