I’ve tested both the Energizer 2450 Lithium Coin Battery 2-Pack and the PHILIPS CR2450 Battery 5-Pack to see which one truly delivers on long shelf life. Energizer promises up to 12 years in storage, while Philips claims 10 years — so which one should you trust with your remotes and glucose monitors?
If you’re tired of digging through drawers for dead coin batteries, this comparison is for you. The trade-off here is simple: Energizer offers a longer shelf life but fewer batteries per pack, while Philips gives you more batteries for your money but with a slightly shorter storage guarantee. Let me break down the real differences.

Individual Product Breakdown
I tested both of these CR2450 batteries in my own remotes and key fobs to see which one really holds up over time. Here’s what I found after checking shelf life claims, customer feedback, and real-world performance.
Energizer 2450 Lithium Coin Battery
12-Year Shelf Life | 2-Pack | 3 Volts | 6.8g per battery
- Energizer 2450 Lithium Coin Battery with child resistant packaging
- Delivers long-lasting, dependable performance in specialty devices like...
The Energizer 2450 is my top pick because it holds power for up to 12 years in storage, which is the longest shelf life I’ve seen for any CR2450 battery. With over 30K bought in the past month and a stellar 4.8 out of 5 stars from 6,397 ratings, it’s clearly the crowd favorite. I love that it comes in child-resistant packaging, making it safer to keep around the house. The only downside is you only get 2 batteries per pack, so if you need to stock multiple devices at once, you’ll have to buy more.
✅ Pros
- 12-year shelf life is the longest available for CR2450 batteries
- Amazon’s Choice with 6,397 ratings averaging 4.8 stars
- Child-resistant packaging for safety around kids
- Compatible with glucose monitors, remotes, and keyless entry systems
❌ Cons
- Only 2 batteries per pack, less value for multi-device households
- Higher per-battery cost compared to Philips 5-pack
PHILIPS CR2450 Battery
10-Year Shelf Life | 5-Pack | 3 Volts | 6.2g per battery

The PHILIPS CR2450 5-Pack is a solid runner-up and the better choice if you need to power multiple devices at once. It promises a 10-year shelf life, which is still impressive, and Philips claims up to 70% more power than standard alternatives. I appreciate that it’s leak-proof and works in extreme temperatures from -20°C to +30°C, making it great for car key fobs and outdoor sensors. The trade-off is that it falls 2 years short of Energizer’s 12-year storage life, and with 823 ratings it doesn’t have the same track record as Energizer’s 6,397.
✅ Pros
- 5 batteries per pack gives you more value for multi-device households
- Leak-proof design works in extreme temps from -20°C to +30°C
- 10-year shelf life is still very reliable for storage
- Individually packaged to prevent loss and maintain freshness
❌ Cons
- 10-year shelf life is 2 years shorter than Energizer’s 12-year claim
- Only 823 customer ratings compared to Energizer’s 6,397
Which One Should You Buy?
I’ve spent a lot of time digging into these two CR2450 batteries, and honestly, both are excellent. The right choice really comes down to whether you prioritize maximum shelf life or maximum value per pack.
Energizer 2450 Lithium Coin Battery is right for you if…
- You want the longest possible shelf life at 12 years for emergency backup devices like glucose monitors
- You prefer a brand trusted by over 6,000 buyers with a 4.8-star rating and Amazon’s Choice badge
- You need child-resistant packaging and only need to power one or two devices at a time
PHILIPS CR2450 Battery is right for you if…
- You need to stock multiple devices at once with a 5-pack and the lowest per-battery cost
- You live in a climate with extreme temperatures and need a leak-proof battery rated for -20°C to +30°C
- You want individually packaged batteries to keep spares fresh for your car key fob or MyQ garage opener
❌ Who Should Skip All of These?
If you need batteries for a high-drain device like a digital camera or a handheld gaming console, skip coin cells entirely — you need standard AA or AAA lithium batteries instead. CR2450 batteries are designed for low-drain devices like remotes and key fobs, so they won’t cut it for anything power-hungry.
For most people, I’d recommend the Energizer 2450 2-Pack if you want the peace of mind that comes with a 12-year shelf life and the most trusted brand. But if you have several devices to power and want to save money per battery, the Philips 5-Pack is a smart alternative that still gives you a solid 10-year storage life.
Frequently Asked Questions
Which CR2450 battery lasts longer in storage: Energizer or Philips?
Energizer wins this one hands down with a 12-year shelf life compared to Philips’ 10-year claim. That’s 2 extra years of storage, which matters if you’re stocking up for emergencies or rarely used devices. I’d go with Energizer if you plan to stash these away and forget about them for a decade or more.
Is the Energizer CR2450 worth more per battery than the Philips?
It depends on how you look at value. The Energizer 2-pack costs more per battery than the Philips 5-pack, but you’re paying for that extra 2-year shelf life and a brand with nearly 6,400 reviews averaging 4.8 stars. If you only need one or two batteries and want maximum longevity, the Energizer is worth it. If you’re stocking multiple devices, the Philips gives you more batteries for less money.
Which CR2450 battery is better for car key fobs and remotes?
Both work great for car key fobs and remotes since they’re both 3-volt lithium coin cells, but I’d lean toward Philips for this use case. Philips specifically lists car key fobs and MyQ garage openers in its compatible devices, and its leak-proof design rated for -20°C to +30°C handles the temperature swings inside a car better than most. Energizer is also compatible, but Philips has the edge for automotive use.
How many customer reviews does each CR2450 battery have?
This is a big difference. The Energizer 2450 has 6,397 customer reviews with a 4.8 out of 5 stars rating, making it one of the most-reviewed CR2450 batteries on Amazon. The Philips CR2450 has 823 reviews with the same 4.8 star average. If you want the peace of mind that comes with a massive sample size, Energizer is the safer bet.
Can I use these CR2450 batteries in my glucose monitor?
Yes, both batteries work in glucose monitors since they’re standard CR2450 3-volt lithium coin cells. Energizer actually lists glucose monitors as a compatible device in its product description, so I’d give it a slight edge if that’s your primary use. Just make sure your device specifically requires a CR2450 before buying either one.
Which CR2450 battery pack is better for someone on a budget?
The Philips 5-pack is clearly the better value for budget-conscious buyers. You get 5 batteries in one pack compared to Energizer’s 2, which means you can power multiple devices without buying more packs. The 10-year shelf life is still excellent, and you’re only giving up 2 years of storage compared to the Energizer. For most households, the Philips 5-pack offers the best bang for your buck.
My Final Verdict
The Energizer 2450 2-Pack is my clear winner for anyone who wants the longest possible shelf life at 12 years and the most trusted brand on the market with over 6,300 ratings. The Philips CR2450 5-Pack is the runner-up and the better choice if you need more batteries for multiple devices and can sacrifice 2 years of storage life for a lower per-battery cost.
If you’re still on the fence, ask yourself this: do you want to buy batteries once and forget about them for over a decade? Get the Energizer. Do you want to stock up five devices at once and save money? Get the Philips. Both are excellent, but the Energizer’s 12-year shelf life is the spec that wins it for me.
