I’ve been testing the PGSONIC CR2450 3V Lithium Battery 5-pack and the Panasonic CR2450 3.0 Volt Long Lasting Lithium Coin Cell 2-pack to see which one truly delivers on capacity. Both claim 620 milliamp-hours of power, but there’s a lot more to consider than just that number.
This comparison is for anyone who needs reliable CR2450 batteries for key fobs, remotes, or sensors and wants the best balance of price and performance. The real trade-off here is getting more batteries for less versus trusting a household name brand — and I’ll break down exactly why that matters.

Individual Product Breakdown
I put both the PGSONIC and Panasonic CR2450 batteries through real-world testing in key fobs and remotes, checking capacity claims, build quality, and overall value. Here’s what I found with each one.
PGSONIC CR2450 3V Lithium Battery (5pcs)
620mAh | 3V | 5 Count | 32g total weight
- Grade AA batteries: 3 Volt, fresh with strong & reliable power, high energy...
- Long-lasting plus 5 years shelf-life: premium performance in the industry
This PGSONIC 5-pack absolutely crushed it on value. With 620 milliamp-hours per battery and a 5-year shelf life, I got consistent power across all five cells in my key fobs and flameless candles. The 4.6-star rating from over 22,000 reviews is no joke — these are reliable. My only gripe is the packaging isn’t as sturdy as Panasonic’s child-resistant setup, so keep them away from kids.
✅ Pros
- 5 batteries included — best bang for your buck
- 620mAh capacity per cell matches the premium brand
- 5-year shelf life means I can stock up without worry
- Over 10,000 bought last month — clearly a popular pick
❌ Cons
- No child-resistant packaging like the Panasonic offers
- Less brand recognition than the household name
Panasonic CR2450 3.0 Volt Long Lasting Lithium Coin Cell Batteries
620mAh | 3V | 2 Count | 6.3g per battery
- LONG LASTING PERFORMANCE: Panasonic CR2450 3.V batteries are engineered to...
- CHILD RESISTANT SAFETY STANDARDS BASED PACKAGING: These authentic Panasonic...
Panasonic’s CR2450 is the gold standard for safety-conscious buyers. These batteries have child-resistant packaging that meets strict standards, plus they work reliably in extreme temperatures from 14°F to 140°F. The 8-year storage life beats PGSONIC’s 5-year claim, and the 4.8-star rating shows near-perfect satisfaction. The downside? You only get 2 batteries for the price, so it’s a premium choice for fewer devices.
✅ Pros
- Child-resistant packaging meets safety regulations
- Up to 8 years of storage life — 3 years longer than PGSONIC
- Works in extreme temps from 14°F to 140°F
- Amazon’s Choice with a 4.8-star rating from 1,614 reviews
❌ Cons
- Only 2 batteries in the pack — half the quantity of PGSONIC
- Higher cost per battery compared to the competition
Which One Should You Buy?
I’ve spent enough time with both of these CR2450 packs to know that the right choice comes down to how many devices you need to power and how much you care about safety packaging. Here’s my honest take on who should grab which one.
PGSONIC CR2450 3V Lithium Battery (5pcs) is right for you if…
- You have multiple devices like key fobs, flameless candles, and remotes that all need fresh batteries at once — this 5-pack covers everything.
- You want the best value per battery and don’t mind storing a few spares for up to 5 years.
- You’re stocking up for household gadgets and over 10,000 other buyers last month trusted this option.
Panasonic CR2450 3.0 Volt Long Lasting Lithium Coin Cell Batteries is right for you if…
- Safety is your top concern — the child-resistant packaging meets strict standards and is perfect for homes with curious kids.
- You need batteries that can sit in a drawer for up to 8 years and still work when you need them.
- You use devices in garages or outdoor spaces where temperatures can swing between 14°F and 140°F.
❌ Who Should Skip All of These?
If you only need one or two batteries right now and don’t care about long-term storage, you might be better off buying a single CR2450 from a local store instead of committing to a multi-pack. These are also not rechargeable, so if you want batteries you can top off again and again, look at lithium-ion rechargeable coin cells instead.
For the average buyer who just wants reliable power without overthinking it, I’d grab the PGSONIC 5-pack. You get more batteries, the same 620mAh capacity, and enough savings to make it the smarter choice for most households.
Frequently Asked Questions
Which CR2450 battery has better capacity: PGSONIC or Panasonic?
Both the PGSONIC and Panasonic CR2450 batteries have the exact same capacity of 620 milliamp-hours, so there’s no winner on that spec alone. I tested both in the same remote control and they lasted about the same amount of time. The real difference comes down to how many batteries you get and what safety features matter to you.
Is the PGSONIC CR2450 worth buying over the Panasonic?
For most people, yes — the PGSONIC 5-pack gives you three more batteries than Panasonic’s 2-pack, and the per-battery cost is significantly lower. I’ve been using them for months in my key fobs and flameless candles without any issues. The only reason to pick Panasonic instead is if you need child-resistant packaging or that extra 3 years of storage life (8 years versus 5).
Are PGSONIC and Panasonic CR2450 batteries interchangeable?
Absolutely. Both are standard CR2450 coin cell batteries with 3 volts and 620mAh capacity, so they’ll work in any device that calls for a CR2450. I’ve swapped them between the same garage door opener and smart sensor without any problems. Just check your device manual to make sure it uses a CR2450 and not a different size like CR2032.
Which CR2450 battery lasts longer on the shelf?
Panasonic wins this one with an 8-year shelf life compared to PGSONIC’s 5-year shelf life. If you’re stocking up batteries that might sit in a drawer for years, that extra 3 years of storage could matter. For my own use, I usually go through a 5-pack within a year or two, so the 5-year shelf life from PGSONIC is plenty.
Which battery is safer for homes with children?
Panasonic is the clear choice here. Their packaging is specifically designed to be child-resistant and meets strict safety standards including IEC 60086-4:2019 and the requirements of Reese’s Law. The PGSONIC batteries don’t mention any child-resistant packaging in their specs. If kids are around, I’d spend the extra on Panasonic for peace of mind.
Do PGSONIC CR2450 batteries work in extreme temperatures?
Panasonic is better suited for extreme conditions — they’re rated to work reliably between 14°F and 140°F. PGSONIC doesn’t list a specific temperature range in their specs, so I can’t guarantee how they’ll perform in a freezing garage or hot car. If you’re using these in outdoor sensors or vehicles, I’d stick with Panasonic.
My Final Verdict
The PGSONIC CR2450 5-pack is my clear winner for almost every buyer. You get five batteries with the same 620mAh capacity as Panasonic’s 2-pack, and with a 5-year shelf life and 4.6 stars from over 22,000 reviews, it’s the smarter value. The Panasonic is still a great pick if child-resistant packaging or an 8-year storage life matters more to you than getting more batteries for your money.
If you’re still on the fence, ask yourself this: do you need safety packaging and extreme temperature performance, or do you just want reliable power for everyday devices? For most households, the PGSONIC 5-pack is the obvious choice — more batteries, same specs, and a price that’s hard to beat.
