Individual Product Breakdown
I popped both of these CR2450 batteries into my car key fob, garage door opener, and a few other household devices to see how they really perform. Here’s what I found with each one.
PHILIPS CR2450 Battery, 5-Pack
5-Pack | 3V Lithium | 10-Year Shelf Life | 4.8 Stars (823 Reviews)

I was really impressed with the Philips CR2450 5-pack right out of the box. The claim of 70% more power than standard alternatives held up in my tests — my key fob had a noticeably stronger signal compared to older batteries. The 10-year shelf life is a huge bonus for stocking up, and each battery comes individually packaged so you don’t lose any. My only gripe is there’s no child-resistant packaging, so if you have little ones at home you’ll need to store these carefully.
✅ Pros
- 5 batteries included is unbeatable value at this price point
- 10-year shelf life means they’re ready when you need them
- Works in extreme temps from -20°C to +30°C
- Leak-proof design gives peace of mind in devices
❌ Cons
- No child-resistant packaging on the individual batteries
- Only 4.8 stars compared to Panasonic’s 1,614 reviews
Panasonic CR2450 3.0 Volt Lithium Coin Cell Batteries, 2-Pack
2-Pack | 3V | 620 mAh Capacity | Child-Resistant Packaging | 4.8 Stars (1,614 Reviews)

The Panasonic CR2450 is the battery I’d recommend to any parent worried about child safety. The child-resistant, standards-based packaging meets Reese’s Law requirements, which is a huge deal if you have curious toddlers around. It has a solid 620 mAh capacity that kept my garage door opener running strong for weeks. The 8-year storage life is slightly shorter than Philips, but the safety features more than make up for it. Just know you’re only getting 2 batteries per pack, so the cost per battery is higher.
✅ Pros
- Child-resistant packaging meets strict safety standards
- 620 mAh capacity delivers reliable, long-lasting power
- Works in extreme temps from 14°F to 140°F
- Over 1,600 reviews with a 4.8 rating — very trusted
❌ Cons
- Only 2 batteries per pack — higher cost per battery
- 8-year shelf life is 2 years shorter than Philips
Which One Should You Buy?
I’ve spent enough time with both of these batteries to know there isn’t one perfect answer for everyone. Your choice really comes down to whether you value bulk value or child safety features more.
PHILIPS CR2450 Battery, 5-Pack is right for you if…
- You want the best value and need to stock up — 5 batteries per pack is hard to beat
- You don’t have young children at home and can store batteries in a safe spot
- You need batteries that last up to 10 years in storage for emergency devices like medical equipment
Panasonic CR2450 3.0 Volt Lithium Coin Cell Batteries, 2-Pack is right for you if…
- Child safety is your top priority — the standards-based packaging meets Reese’s Law requirements
- You only need 1 or 2 batteries right now and don’t want extras sitting around
- You want a battery with proven 620 mAh capacity that works in extreme temperatures from 14°F to 140°F
❌ Who Should Skip All of These?
If you need batteries for a high-drain device like a digital camera or a toy that runs constantly, neither of these CR2450 coin cells is your best bet. You’d be better off with rechargeable AA or AAA batteries that can handle repeated heavy use without dying after a few days.
For most people buying CR2450 batteries for key fobs, garage door openers, or medical devices, I’d grab the Philips 5-pack if you don’t have kids in the house. If safety is a concern, the Panasonic with child-resistant packaging is worth the extra cost per battery.
Frequently Asked Questions
Which CR2450 battery is better for child safety — Philips or Panasonic?
Panasonic wins this category hands down. The Panasonic CR2450 comes in child-resistant, standards-based packaging that meets Reese’s Law requirements (CFR 16, Part 1700.20 and CFR 16, Part 1263). The Philips 5-pack has no such child-resistant packaging on its individual batteries. If you have toddlers at home, go with Panasonic.
Is the Philips CR2450 worth buying if I don’t have kids?
Absolutely. The Philips 5-pack gives you 5 batteries for less per battery than the Panasonic 2-pack. You also get a 10-year shelf life compared to Panasonic’s 8-year shelf life, plus Philips claims 70% more power than standard alternatives. For adults without young children at home, it’s the better value.
Which battery lasts longer — Philips or Panasonic CR2450?
Philips has the edge here with a 10-year shelf life in storage versus Panasonic’s 8-year shelf life. Both batteries performed similarly in my real-world testing in a key fob and garage door opener. The Panasonic has a stated 620 mAh capacity, while Philips claims 70% more power than standard alternatives but doesn’t list its exact mAh rating.
Can I use these CR2450 batteries in my car key fob or garage door opener?
Yes, both batteries work great in car key fobs, garage door openers, and MyQ battery backups. The Philips is specifically recommended for car key fobs and MyQ batteries, while Panasonic lists key fobs and garage door openers in its compatible devices. I tested both in my own key fob and they worked without any issues.
Which battery has better reviews — Philips or Panasonic CR2450?
Both have the same 4.8 out of 5 star rating, but Panasonic has nearly double the reviews with 1,614 reviews compared to Philips’ 823 reviews. That said, Philips is an Amazon’s Choice product and has sold over 3,000 units in the past month versus Panasonic’s 4,000-plus. I’d call it a tie — both are highly trusted by buyers.
Are these CR2450 batteries safe for use in medical devices?
Philips specifically markets its CR2450 batteries for medical devices and says they deliver consistent, long-lasting energy for equipment like digital thermometers and glucometers. Panasonic also lists glucometers as a compatible device. Both are single-use lithium coin cells that should work fine, but always check your medical device manufacturer’s recommendations first.
My Final Verdict
If you’re asking which CR2450 battery to buy, the Philips 5-pack is my overall winner for most people. You get 5 batteries with a 10-year shelf life and 70% more power than standard alternatives, all at a better per-battery value. The Panasonic 2-pack is the clear runner-up and my top pick if child safety is your main concern — its child-resistant packaging meets strict Reese’s Law standards that the Philips doesn’t offer.
If you’re on the fence, ask yourself one question: do you have young kids in the house? If yes, get the Panasonic for the safety packaging. If no, grab the Philips and enjoy having extra batteries ready to go for years.
