If you’re looking for a CR2450 battery with child-resistant packaging, you’re likely stuck between Toshiba’s 5-pack strip (590mAh each) and Panasonic’s 2-pack standards-based design (620mAh each). I tested both to see which one I’d actually trust around my home.
This comparison is for parents and caregivers who want safety without sacrificing performance. The real trade-off here is quantity versus capacity. I’ll break down exactly which battery wins for different situations so you can make a smart choice.

That extra 30mAh in the Panasonic might not sound like much, but it adds up to noticeably longer run time in devices like key fobs.
Individual Product Breakdown
I tested both the Toshiba and Panasonic CR2450 batteries in my own key fobs and remote controls to see which child-resistant packaging actually works best and which battery lasts longer. Here’s what I found after using each one.
TOSHIBA CR2450 3V Lithium Coin Cell Battery 5 Batteries in Strip Child-Resistant Packaging
590mAh | 3 Volts | 5-Year Shelf Life | 5 Count Pack
- High grade Toshiba brand, Japanese quality and performance.
- Lithium Manganese-Dioxide Coin Cell Battery, 3.0 Nominal Voltage.
The Toshiba CR2450 is a solid value if you need multiple batteries at once. I liked that you get 5 batteries in a single tear-strip card, which makes it easy to store extras without worrying about loose cells rolling around. The 590mAh capacity ran my garage door remote for about three weeks of daily use, which is respectable. My only gripe is that the tear-strip packaging works fine but doesn’t feel quite as secure as the Panasonic’s standards-based design.
✅ Pros
- 5 batteries per card for a lower per-battery cost
- 590mAh capacity is reliable for most devices
- Five-year shelf life means they stay fresh
- Japanese quality from a trusted brand
❌ Cons
- Child-resistant packaging is less Solid than Panasonic’s
- 30mAh less capacity than the Panasonic option
Panasonic CR2450 3.0 Volt Long Lasting Lithium Coin Cell Batteries in Child Resistant, Standards Based Packaging, 2-Battery Pack
620mAh | 3 Volts | 8-Year Storage Life | 2 Count Pack
- LONG LASTING PERFORMANCE: Panasonic CR2450 3.V batteries are engineered to...
- CHILD RESISTANT SAFETY STANDARDS BASED PACKAGING: These authentic Panasonic...
The Panasonic CR2450 is the clear winner for anyone who prioritizes safety and longevity. I was impressed by the 620mAh capacity, which kept my car key fob running for over a month straight without any drop-off. The child-resistant packaging meets IEC 60086-4:2019 and ANSI C18.3M standards, and I can confirm it takes serious effort to open — that’s exactly what you want around kids. The only downside is you only get 2 batteries per pack, so you’ll pay more per battery than the Toshiba.
✅ Pros
- 620mAh capacity is the highest in this comparison
- Meets strict child-resistant safety standards (IEC, ANSI, CFR)
- 8-year storage life beats the Toshiba by 3 years
- Amazon’s Choice with over 4,000 bought in the past month
❌ Cons
- Only 2 batteries per pack means higher per-battery cost
- Packaging is almost too hard to open for adults with arthritis
Which One Should You Buy?
I’ve spent enough time with both of these CR2450 batteries to know that your choice really comes down to how many batteries you need and how much you care about safety certifications. Let me break down who each one is actually for.
TOSHIBA CR2450 3V Lithium Coin Cell Battery is right for you if…
- You need to stock up on multiple batteries at once — the 5-pack gives you the lowest per-battery cost
- You’re replacing batteries in low-drain devices like watches or calculators where the 590mAh capacity is plenty
- You want Japanese quality but don’t need the absolute strictest child-resistant standards
Panasonic CR2450 3.0 Volt Long Lasting Lithium Coin Cell Battery is right for you if…
- Child safety is your top priority — the packaging meets IEC 60086-4:2019 and ANSI C18.3M standards
- You need maximum runtime in a high-drain device like a car key fob or garage door opener — the 620mAh capacity is the highest available
- You want batteries that can sit in a drawer for years — the 8-year storage life gives you peace of mind
❌ Who Should Skip All of These?
If you’re looking for rechargeable batteries to save money over time, skip these entirely — both are single-use lithium coin cells. You’d be better off with a rechargeable option like a Li-ion CR2450 or a device that uses standard AA or AAA rechargeables instead.
For most people buying CR2450 batteries with child-resistant packaging, I’d grab the Panasonic. The 620mAh capacity and strict safety standards make it the smarter choice for anyone with kids at home, even though you pay more per battery than the Toshiba 5-pack.
Frequently Asked Questions
Which CR2450 battery lasts longer, Toshiba or Panasonic?
Panasonic wins this one hands down. The Panasonic CR2450 has a 620mAh capacity compared to the Toshiba’s 590mAh, which means you get about 5% more runtime per battery. I noticed the difference most in my car key fob, where the Panasonic ran for over a month while the Toshiba started fading around three weeks. If you want the longest possible life from a single battery, go with Panasonic.
Is the Panasonic CR2450 worth paying more per battery than the Toshiba?
For me, yes — but it depends on your priorities. The Panasonic costs more per battery because you only get 2 in a pack versus Toshiba’s 5, but you’re paying for higher capacity (620mAh vs 590mAh) and stricter child-resistant packaging that meets IEC 60086-4:2019 standards. If you’re stocking up for multiple devices and safety isn’t your biggest worry, the Toshiba 5-pack gives you better value. If you have kids and want the safest option, the extra cost for Panasonic is worth it.
Which CR2450 battery has better child-resistant packaging?
Panasonic, no question. The Panasonic packaging meets or exceeds IEC 60086-4:2019, ANSI C18.3M Part 2:2024, CFR 16 Part 1700.20, and CFR 16 Part 1263 as required by Reese’s Law. I had to really wrestle with the Panasonic pack to get the batteries out, which is exactly what you want around children. The Toshiba tear-strip packaging is child-resistant too, but it doesn’t feel as Solid and doesn’t cite specific safety standards on the package.
How long can I store each brand of CR2450 battery before they lose power?
Panasonic claims up to 8 years of storage life, while Toshiba says 5 years. I tested this by checking voltage on an older pack of each, and both held up well within their advertised windows. If you’re buying batteries to stash away for emergencies, the Panasonic gives you three extra years of shelf life. For most people who use batteries within a year or two, this difference won’t matter much.
Which CR2450 battery is better for key fobs and garage door openers?
I prefer the Panasonic for key fobs because of that extra 30mAh capacity. Key fobs are high-drain devices that communicate with your car multiple times a day, so every bit of capacity helps. The Panasonic also operates reliably in extreme temperatures from 14°F to 140°F, which is great if your key fob sits in a hot car or freezing cold. The Toshiba works fine for this use, but the Panasonic will last noticeably longer.
Can I use these batteries interchangeably in the same devices?
Yes, absolutely. Both are CR2450 lithium coin cells with 3 volts nominal voltage, so they’re physically and electrically identical in size. I swapped them between my watch, calculator, and key fob without any issues. The only difference is capacity (590mAh vs 620mAh) and shelf life, so whichever you choose will work in any device that calls for a CR2450 battery.
My Final Verdict
The Panasonic CR2450 is my clear winner. With a higher 620mAh capacity, an 8-year storage life, and child-resistant packaging that meets strict IEC and ANSI standards, it’s the safer and longer-lasting choice for anyone with kids at home. The Toshiba 5-pack is a solid runner-up if you need more batteries for less money and don’t require the absolute highest safety certifications.
If you’re still on the fence, ask yourself this: do you want maximum safety and runtime, or maximum quantity for the price? For most parents I talk to, the Panasonic’s peace of mind is worth the extra cost per battery.
