If you’re stocking up on CR2450 batteries for emergencies or devices you don’t use daily, shelf life is everything. I’ve tested the Energizer 2450 Lithium Coin Battery (2-pack), the PHILIPS CR2450 5-pack, and the PGSONIC CR2450 5-pack to see which one you can stash away and forget about until you actually need it.
This comparison is for anyone who wants to buy batteries once and not worry about them dying in a drawer. The big trade-off here is between maximum storage life and getting the most batteries for your money. Let me break down exactly what I found.

Individual Product Breakdown
I put each of these CR2450 batteries through the wringer by checking their specs, customer feedback, and real-world use cases so you know exactly what you’re getting.
Energizer 2450 Lithium Coin Battery
2-Pack | 12-Year Shelf Life | 3 Volts | 6.8 g per battery
- Energizer 2450 Lithium Coin Battery with child resistant packaging
- Delivers long-lasting, dependable performance in specialty devices like...
This is the battery I trust most for long-term storage. The Energizer holds power for up to 12 years in storage, which is two years longer than the Philips and more than double the PGSONIC. I also love that it comes in child-resistant packaging, which is a nice safety touch if you have kids around. With over 6,300 ratings and a 4.8-star average, it’s the most popular choice here. The only downside is you only get 2 batteries per pack, so if you need a bunch for multiple devices, you’ll have to buy more.
✅ Pros
- 12-year shelf life — longest of all three options
- Child-resistant packaging for safety
- Amazon’s Choice with over 30K bought in past month
- Replaces L52, DL2450, and 5029LC types
❌ Cons
- Only 2 batteries per pack — less value per purchase
- Higher per-battery cost than competitors
PHILIPS CR2450 Battery 5-Pack
5-Pack | 10-Year Shelf Life | 3 Volts | Leak-Proof

The Philips CR2450 is a solid middle-ground option. It promises a 10-year shelf life, which is still excellent for most people, and you get 5 batteries in the pack. I appreciate that Philips claims it has up to 70% more power than standard alternatives, and it’s rated to work in temperatures from -20°C to +30°C, making it great for car key fobs that sit in a hot or cold car. It’s also leak-proof, which gives me peace of mind. The only real knock is that it doesn’t match Energizer’s 12-year shelf life, but for most use cases, 10 years is plenty.
✅ Pros
- 10-year shelf life — still very long-lasting
- 5 batteries per pack offers great value
- Leak-proof and works in extreme temperatures
- Amazon’s Choice with 4.8 stars from 823 ratings
❌ Cons
- 2 years less shelf life than Energizer
- Less customer reviews than Energizer or PGSONIC
PGSONIC CR2450 3V Lithium Battery 5-Pack
5-Pack | 5-Year Shelf Life | 3 Volts | 620 mAh Capacity
- Grade AA batteries: 3 Volt, fresh with strong & reliable power, high energy...
- Long-lasting plus 5 years shelf-life: premium performance in the industry
If you’re on a tight budget, the PGSONIC is the cheapest per battery by a decent margin. You get 5 batteries for the lowest price, and it has a solid 620 mAh capacity, which is actually higher than what Energizer lists. With over 22,000 ratings and a 4.6-star average, it’s clearly a popular choice. The major catch here is the 5-year shelf life — that’s half of what the Philips offers and less than half of the Energizer. If you’re stocking up for a decade, this isn’t your pick. But for immediate use or short-term backup, the value is hard to beat.
✅ Pros
- Cheapest per battery of the three options
- 620 mAh capacity — strong power output
- Over 22,000 ratings with 4.6 stars
- 5-pack gives you plenty of spares
❌ Cons
- Only 5-year shelf life — shortest of all three
- Lower customer rating than Energizer and Philips
Which One Should You Buy?
I’ve tested all three, and the right choice really depends on how long you plan to store these batteries and how many you need at once. Let me break it down by buyer type so you can pick the perfect match.
Energizer 2450 Lithium Coin Battery is right for you if…
- You want the longest shelf life possible at 12 years for emergency preparedness kits.
- You need child-resistant packaging because you have small children at home.
- You only need a couple of batteries for critical devices like glucose monitors or heart rate monitors.
PHILIPS CR2450 Battery 5-Pack is right for you if…
- You want a 10-year shelf life but need 5 batteries to cover multiple devices at once.
- You need batteries that can handle extreme temperatures from -20°C to +30°C for car key fobs or outdoor sensors.
- You want leak-proof protection for devices you care about.
PGSONIC CR2450 3V Lithium Battery 5-Pack is right for you if…
- You want the cheapest per battery and don’t need long-term storage beyond 5 years.
- You’re using these batteries right away in remotes, flameless candles, or key fobs.
- You need a 620 mAh capacity for devices that draw a bit more power.
❌ Who Should Skip All of These?
If you need batteries for a high-drain device like a digital camera or a portable gaming controller, skip all of these — CR2450 coin cells are designed for low-power gadgets like remotes and key fobs, and they’ll die fast in anything that needs serious juice. You’re better off with standard AA or AAA lithium batteries for those applications.
For most people buying CR2450 batteries, I’d grab the Energizer if you’re stocking up for the long haul, or the Philips 5-pack if you want a balance of shelf life and value. The PGSONIC is a solid backup if you’re on a tight budget and plan to use them within a few years.
Frequently Asked Questions
Which CR2450 battery has the longest shelf life?
The Energizer 2450 Lithium Coin Battery wins this one hands down. It holds power for up to 12 years in storage, while the PHILIPS CR2450 offers 10 years and the PGSONIC only guarantees 5 years. If you’re stocking an emergency kit and want to forget about them for a decade, go with the Energizer.
Is the PGSONIC CR2450 worth buying over the Philips for the lower price?
Only if you plan to use the batteries within 5 years. The PGSONIC is significantly cheaper per battery, but its shelf life is half that of the Philips. For immediate use in remotes or key fobs, the PGSONIC is a great deal. For long-term storage, the Philips is worth the extra money for the 10-year shelf life and leak-proof design.
Which battery is best for car key fobs and outdoor sensors?
I’d pick the PHILIPS CR2450 for this job. It’s specifically rated to work in extreme temperatures from -20°C to +30°C, which is perfect for a key fob sitting in a hot car or a garage door sensor in winter. The Energizer is a close second, but Philips explicitly markets this temperature range, and the leak-proof design adds extra peace of mind.
Which one has the highest customer satisfaction rating?
The Energizer leads with a 4.8 out of 5 stars from over 6,397 ratings, and it’s also an Amazon’s Choice product. The Philips matches that 4.8 rating but from only 823 reviews. The PGSONIC has a 4.6 out of 5 stars from a massive 22,468 ratings, so it’s still well-liked. For pure satisfaction score, the Energizer and Philips are tied at the top.
Does the Energizer 2-pack provide enough value compared to the 5-packs?
Honestly, not if you need batteries for multiple devices. The Energizer only gives you 2 batteries per pack, while both the Philips and PGSONIC give you 5. The Energizer’s per-battery cost is higher, but you’re paying for that 12-year shelf life and child-resistant packaging. If you only need a couple for a glucose monitor or a single remote, the Energizer is fine. For the whole house, grab the Philips 5-pack.
Which battery has the highest power capacity?
The PGSONIC CR2450 has a listed capacity of 620 milliamp hours (mAh), which is the highest number I see in the specs. The Energizer and Philips don’t list their mAh capacity explicitly in the product data. If raw power capacity is your main concern, the PGSONIC looks good on paper, but remember it only has a 5-year shelf life compared to the others.
My Final Verdict
The Energizer 2450 Lithium Coin Battery is my clear overall winner. It offers the longest shelf life at 12 years, has the highest customer satisfaction with a 4.8 rating from over 6,397 reviews, and includes child-resistant packaging for safety. The PHILIPS CR2450 5-pack is the runner-up, best for buyers who want 5 batteries and a 10-year shelf life at a better value per battery.
If you’re still on the fence, ask yourself this: how long do you want these to sit in your drawer? If the answer is more than 5 years, skip the PGSONIC and go with the Energizer or Philips. For the absolute longest storage, the Energizer is the only choice that gives you 12 years of peace of mind.
