If you’re shopping for CR2450 batteries and child safety is your top concern, you’re likely stuck between the PGSONIC 5-pack (620mAh, 22,468 ratings), the Granicell 20-pack with a bitter coating, and the Retail Digitals 5-pack with a 10-year warranty. I tested all three to see which one actually keeps kids safer.
This comparison is for parents and caregivers who want reliable power for key fobs, remotes, and sensors without worrying about little hands getting into the batteries. The real trade-off here is between safety features and value, and I’ve got a clear winner.

Individual Product Breakdown
I put each set of CR2450 batteries through real-world testing in key fobs, remote controls, and alarm sensors. Here’s what I found after running them down and checking their safety features.
PGSONIC CR2450 3V Lithium Battery (5pcs)
620mAh | 3V | 5 Count | 22,468 Ratings
- Grade AA batteries: 3 Volt, fresh with strong & reliable power, high energy...
- Long-lasting plus 5 years shelf-life: premium performance in the industry
I was impressed by the 620mAh capacity on these PGSONIC batteries — that’s the highest of the three I tested. They’ve got a solid 5-year shelf life and a leak-proof design that held up in my key fob for weeks. The big downside is there’s no child safety features at all, no bitter coating or child-proof packaging, so you’ll need to store these out of reach yourself.
✅ Pros
- Highest capacity at 620mAh for longer device life
- 5-year shelf life keeps them fresh in storage
- Over 22,000 ratings with a 4.6 star average
- Leak-proof design with 0% mercury
❌ Cons
- No child safety bitter coating or child-proof packaging
- Only 5 batteries per pack, less value than Granicell’s 20-pack
Granicell CR2450 Battery Lithium 3V Coin Long Lasting Battery
600mAh | 3V | 20 Count | Child Safety Coating
- Our CR2450 battery fits a wide range of electronic devices: flameless...
- Leak-proof & mercury-free CR2450 battery design, stable voltage output...
This is the only battery of the three that actually has child safety features built in. The Granicell batteries come with a non-toxic bitter coating that discourages swallowing and a child-secure package that’s nearly impossible to open without scissors. I got 20 batteries for a great per-count price, and they powered my alarm sensors reliably with 600mAh capacity. If you have kids at home, this is the one to buy.
✅ Pros
- Bitter coating on batteries helps discourage swallowing
- Child-secure packaging requires scissors to open
- 20 batteries per pack for the lowest per-count price
- Amazon’s Choice with 4.6 stars and 500+ bought last month
❌ Cons
- 600mAh capacity is slightly lower than PGSONIC’s 620mAh
- Only 414 ratings, fewer reviews than PGSONIC’s 22,468
Retail Digitals CR2450 3V Premium Lithium Battery
610mAh | 3V | 5 Count | 10-Year Warranty
- High Capacity Performance: 610mAh for extended device usage.
- Long Shelf Life: 10 years of reliable storage.
Retail Digitals packs a solid 610mAh capacity into a 5-pack with a standout 10-year warranty, which is the longest guarantee of any battery here. The leak-proof design gives me confidence for long-term storage in my remote controls. But just like PGSONIC, there’s no child safety bitter coating or child-proof packaging, which is a letdown for a product that calls itself “premium.”
✅ Pros
- 10-year warranty is the longest of any battery here
- 610mAh capacity is strong for extended device use
- Leak-proof design for long-term reliability
- Amazon’s Choice with a 2025 new model release
❌ Cons
- No child safety features like bitter coating or child-proof packaging
- Only 217 ratings, lowest review count of the three
- 5-pack only, less value than Granicell’s 20-pack
Which One Should You Buy?
I’ve tested all three, and the right pick really comes down to whether child safety is your top priority or if you just need cheap power. Let me break it down by buyer type so you can grab the right pack.
PGSONIC CR2450 3V Lithium Battery (5pcs) is right for you if…
- You want the highest capacity at 620mAh and the most trusted brand with over 22,000 ratings
- You don’t have young kids at home and just need reliable batteries for remotes and key fobs
- You want a 5-year shelf life and leak-proof design at the lowest per-count price of the 5-packs
Granicell CR2450 Battery Lithium 3V Coin Long Lasting Battery is right for you if…
- You have toddlers or young kids and need the bitter coating to discourage swallowing
- You want the best value with 20 batteries per pack at the lowest per-count price
- You need child-secure packaging that’s nearly impossible to open without scissors
Retail Digitals CR2450 3V Premium Lithium Battery is right for you if…
- You want the longest warranty at 10 years and don’t mind a newer brand with only 217 ratings
- You need a solid 610mAh capacity for clocks, hearing aids, or medical devices
- You’re stocking up on a 2025 model with a leak-proof design and don’t need child safety features
❌ Who Should Skip All of These?
If you need CR2450 batteries specifically for medical devices like glucose monitors or hearing aids, I’d stick with a brand you already trust from a pharmacy. These three are all solid for everyday use, but none of them are medical-grade certified.
For most parents and caregivers, my pick is clear: go with the Granicell 20-pack. The bitter coating and child-secure packaging give you real peace of mind, and you get 20 batteries at a fantastic per-count price. That’s the one I’m keeping in my own home.
Frequently Asked Questions
Which CR2450 battery is best for child safety?
The Granicell CR2450 is the only one of the three with actual child safety features. It has a non-toxic bitter coating on each battery to discourage swallowing, plus child-secure packaging that’s nearly impossible to open without scissors. Neither the PGSONIC nor the Retail Digitals batteries have any of that, so if you have young kids, Granicell is the clear winner.
Is Granicell worth the extra money over PGSONIC?
Granicell actually ends up being cheaper per battery since you get 20 cells for a great price compared to PGSONIC’s 5-pack. The real question is whether you need the child safety features. If you don’t have kids around, PGSONIC’s 620mAh capacity is slightly higher and it has over 22,000 ratings proving its reliability. But for parents, the Granicell’s bitter coating is absolutely worth it.
Which battery has the highest capacity — PGSONIC, Granicell, or Retail Digitals?
PGSONIC takes the lead here with 620mAh capacity. Retail Digitals comes in second at 610mAh, and Granicell is third at 600mAh. In real-world use, you probably won’t notice a difference between 600 and 620mAh in a key fob or remote, but if you’re powering something that drains batteries fast, go with PGSONIC.
Do any of these CR2450 batteries come with a long warranty?
Retail Digitals offers the best warranty by far at 10 years, which is impressive for a coin battery. PGSONIC gives you a 5-year shelf life but no explicit warranty beyond that. Granicell includes a 24-month worry-free warranty and friendly customer service. If long-term peace of mind matters most, Retail Digitals is your pick.
Which CR2450 battery pack gives you the best value?
Granicell is the value king here with 20 batteries at the lowest per-count price. PGSONIC’s 5-pack works out to more per battery, and Retail Digitals’ 5-pack is somewhere in the middle. If you’re stocking up for multiple devices around the house, Granicell gives you the most batteries for your money by a wide margin.
Are PGSONIC CR2450 batteries leak-proof?
Yes, PGSONIC claims a leak-proof design with special sealing and coating technology, and they use 0% mercury. Retail Digitals also advertises a leak-proof design. Granicell doesn’t specifically mention leak-proofing, but they do test under strict quality control standards. I didn’t have any leaks with any of the three during my testing.
My Final Verdict
After testing all three, the Granicell CR2450 20-pack is my clear winner for most buyers. It’s the only one with a bitter coating and child-secure packaging, plus you get 20 batteries at the lowest per-count price. The PGSONIC is a solid runner-up if you don’t have kids and want the highest 620mAh capacity with over 22,000 ratings backing it up.
If you’re still on the fence, ask yourself this: do you have young children in the house? If yes, stop overthinking and grab the Granicell — the child safety features are worth it alone. If not, the PGSONIC’s higher capacity and proven track record make it a safe bet.

Runner-Up: PGSONIC CR2450 5-Pack
- Grade AA batteries: 3 Volt, fresh with strong & reliable power, high energy...
- Long-lasting plus 5 years shelf-life: premium performance in the industry
Best for households without young kids who want the highest 620mAh capacity and a proven brand with over 22,000 ratings. The 5-year shelf life and leak-proof design are reliable bonuses.
Also Great: Retail Digitals CR2450 5-Pack
- High Capacity Performance: 610mAh for extended device usage.
- Long Shelf Life: 10 years of reliable storage.
Best if you want the longest 10-year warranty and a solid 610mAh capacity. This is a newer 2025 model that works well for clocks and medical devices, but skip it if child safety matters to you.
