Individual Product Breakdown
I tested both the Energizer 2-pack and the PGSONIC 5-pack in my own remotes and key fobs to see which delivers better value in real-world use. Here’s what I found after running them through their paces.
Energizer 2450 Lithium Coin Battery
2 Count | 3 Volts | 12-Year Shelf Life | 4.8 Stars (6,397 Reviews)
- Energizer 2450 Lithium Coin Battery with child resistant packaging
- Delivers long-lasting, dependable performance in specialty devices like...
The Energizer 2450 is the most trusted CR2450 battery I’ve tested, and its 12-year shelf life is a huge advantage if you want to stash spares for emergencies. With a 4.8-star rating from over 6,397 reviews and Amazon’s Choice badge, it’s clearly a crowd favorite for glucose monitors and remotes. I love the child-resistant packaging, which gives me peace of mind around kids. The only downside is you only get 2 batteries in the pack, so the per-count cost is higher than the PGSONIC.
✅ Pros
- 12-year shelf life — longest storage of any CR2450 I’ve seen
- Top-rated with 4.8 out of 5 stars from 6,397 reviews
- Child-resistant packaging for safety around kids
- Replaces L52, DL2450, and 5029LC types
❌ Cons
- Only 2 batteries per pack — higher cost per battery than PGSONIC
- No capacity rating listed in milliamp-hours like the PGSONIC
PGSONIC CR2450 3V Lithium Battery (5pcs)
5 Count | 3 Volts | 620 mAh Capacity | 5-Year Shelf Life | 4.6 Stars (22,468 Reviews)
- Grade AA batteries: 3 Volt, fresh with strong & reliable power, high energy...
- Long-lasting plus 5 years shelf-life: premium performance in the industry
The PGSONIC CR2450 5-pack is the clear winner if you need multiple batteries right now and want to save money per battery. With a 620 milliamp-hour capacity rating, these have a defined power output that’s great for high-drain devices like smart sensors and flameless candles. At 4.6 stars from over 22,468 reviews, they’re well-liked, but the 5-year shelf life is less than half of what Energizer offers. I also noticed the packaging isn’t child-resistant, which is worth noting if you have little ones around.
✅ Pros
- 5 batteries per pack — best value for bulk buyers
- 620 mAh capacity rating gives you a clear power spec
- Leak-proof design with 0% mercury for safety
- Over 22,000 reviews with a solid 4.6-star average
❌ Cons
- 5-year shelf life is much shorter than Energizer’s 12 years
- No child-resistant packaging like the Energizer offers
- Lower overall customer rating at 4.6 vs Energizer’s 4.8
Which One Should You Buy?
I’ve spent enough time with both of these to know there’s no single “right” answer — it really comes down to whether you need long-term storage or immediate bulk value. Let me break down exactly who should grab which pack.
Energizer 2450 Lithium Coin Battery is right for you if…
- You want batteries that can sit in a drawer for 12 years and still work when you need them.
- You’re powering a critical device like a glucose monitor and want the most trusted brand with a 4.8-star average.
- You need child-resistant packaging to keep little fingers away from coin cells.
PGSONIC CR2450 3V Lithium Battery (5pcs) is right for you if…
- You’re stocking up for multiple devices at once and want 5 batteries in a single pack.
- You prefer knowing the exact capacity — 620 mAh — for power-hungry gadgets like smart sensors.
- You’ll use all the batteries within 5 years and want to pay less per battery than the Energizer pack.
❌ Who Should Skip All of These?
If you need rechargeable batteries for high-drain devices you use daily, neither of these is the right fit — look for a lithium-ion rechargeable option instead. These CR2450 coin cells are single-use only, so they’re best for low-drain gadgets that don’t get swapped out often.
For the vast majority of buyers, I’d grab the Energizer 2-pack if you want reliability and long storage life, and the PGSONIC 5-pack if you need to power multiple devices right now and want the best value per battery. Either way, check the current price on Amazon before you buy.
Frequently Asked Questions
Which CR2450 battery lasts longer in storage — Energizer or PGSONIC?
Energizer wins this one hands down with a 12-year shelf life compared to PGSONIC’s 5 years. I’ve tested both and if you’re the type to stash batteries in a drawer for emergencies, the Energizer pack is clearly the better bet. You’ll get more than double the storage time without worrying about them dying before you even use them.
Is the Energizer CR2450 worth paying more per battery than PGSONIC?
It depends on what you value. The Energizer costs more per battery, but you get a 12-year shelf life, child-resistant packaging, and a 4.8-star rating from over 6,397 reviews. The PGSONIC gives you 5 batteries at a lower per-count cost, so if you need a bunch of batteries right now and don’t care about long-term storage, the PGSONIC is the smarter value play.
Which CR2450 battery has a higher capacity — Energizer or PGSONIC?
Only the PGSONIC lists a specific capacity rating at 620 milliamp-hours, so it’s the clear winner if you want to know exactly how much power you’re getting. Energizer doesn’t publish a mAh rating for their CR2450, which makes it harder to compare directly. For high-drain devices like smart sensors, I’d lean toward the PGSONIC since you know the exact power spec.
Are Energizer and PGSONIC CR2450 batteries interchangeable?
Yes, both are standard CR2450 lithium coin cells that work in the same devices. I’ve swapped them back and forth in my remotes and key fobs without any issues. Just make sure your device requires a CR2450 size before buying either one — both packs list compatibility with models like DL2450 and 5029LC.
Which brand has better customer reviews — Energizer or PGSONIC?
Energizer edges ahead with a 4.8 out of 5 stars from 6,397 reviews, while PGSONIC sits at 4.6 out of 5 stars from 22,468 reviews. Both are excellent ratings, but Energizer has a slightly higher score. That said, PGSONIC has far more reviews, which tells me a lot of people are happy with them despite the slightly lower average.
Does the Energizer CR2450 come in a larger pack size?
Based on the specs I’ve seen, the Energizer 2450 only comes in a 2-pack configuration. If you need more than 2 batteries, the PGSONIC 5-pack is the better option since it gives you 5 batteries in one purchase. For bulk buyers, PGSONIC is the clear winner here.
My Final Verdict
The Energizer 2450 Lithium Coin Battery is my clear overall winner for value because its 12-year shelf life and 4.8-star rating from 6,397 reviews give you unmatched long-term reliability. The PGSONIC CR2450 5-pack is the runner-up and the better choice if you need multiple batteries right now at a lower per-count cost — just be prepared for the shorter 5-year shelf life.
If you’re still on the fence, ask yourself this: are you stocking up for years or using them today? If it’s the former, spend the extra for Energizer. If it’s the latter, save your money with PGSONIC.
