I tested each of these CR2450 packs by looking at price per count, battery capacity, shelf life, and real customer feedback to see which one actually saves you money without sacrificing performance.
Energizer 2450 Lithium Coin Battery
2-Pack | 3 Volts | 12-Year Shelf Life | 6.8g per Battery
- Energizer 2450 Lithium Coin Battery with child resistant packaging
- Delivers long-lasting, dependable performance in specialty devices like...
The Energizer 2-pack is the most expensive per count here at check current price on Amazon per battery, but you’re paying for that 12-year shelf life and a brand name that 30,000+ people bought last month. I love that the child-resistant packaging makes it safer around kids, and with 4.8 stars from nearly 6,400 reviews, it’s easily the most trusted option. That said, the 2-count is really only practical if you need just a couple batteries for a glucose monitor or remote — it’s not a bulk buy. This is for folks who want the longest storage life and don’t mind paying a premium for peace of mind.
✅ Pros
- 12-year shelf life — best in class for storage
- 4.8 stars from 6,397 ratings — top rated here
- Child-resistant packaging for safety
- Amazon’s Choice badge with 30K+ bought this month
❌ Cons
- Highest price per count at check current price on Amazon each
- Only 2 batteries — terrible for bulk buyers
- No mAh capacity listed to compare against others
PGSONIC CR2450 3V Lithium Battery (5pcs)
5-Pack | 3 Volts | 620 mAh | 5-Year Shelf Life | 32g Total
- 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 5-pack hits a sweet spot at check current price on Amazon per battery with 620 mAh capacity and a 5-year shelf life — and over 22,000 ratings prove people trust it. I like that it’s leak-proof with special sealing and coating technology, plus 10,000+ buyers grabbed it last month. The only catch is the 5-year shelf life is half of Energizer’s 12-year, so if you’re stocking for a decade, this isn’t your pick. It’s ideal for someone who needs a few spares for remotes, key fobs, and sensors without overspending.
✅ Pros
- 620 mAh capacity — great for power-hungry devices
- 4.6 stars from 22,468 reviews — highly proven
- Leak-proof design with mercury-free construction
- 5 batteries at check current price on Amazon each is solid value
❌ Cons
- 5-year shelf life is short compared to Energizer’s 12
- No child-resistant packaging mentioned
- Still more expensive per count than MaxyCell’s 6-pack
MaxyCell 2450 CR2450 Lithium Coin Cell Battery 3V High-Capacity (6 Pack)
6-Pack | 3 Volts | 650 mAh | Leak-Proof | -22°F to +140°F Operating
- Equivalents: DL2450, ECR2450, GPCR2450, CR 2450, BR2450, BR2450-1W...
- Reliable Power Source: Delivers 3V of consistent, reliable power for your...
The MaxyCell 6-pack absolutely crushes the price-per-count competition at check current price on Amazon per battery with a 650 mAh capacity that’s actually higher than PGSONIC’s 620 mAh. I’m impressed it’s leak-proof and corrosion-resistant with an operating range from -22°F to +140°F, which means it handles extreme temperatures better than the others. The catch is it only has 282 ratings compared to Energizer’s 6,397, so the brand doesn’t have as much long-term proof. But for pure value — 6 batteries for less than the price of 2 Energizers — this is the clear winner for anyone buying in bulk.
✅ Pros
- Lowest price per count at check current price on Amazon each
- 650 mAh capacity — highest mAh of all three tested
- Leak-proof and corrosion-resistant with wide temp range
- Amazon’s Choice badge with 2K+ bought last month
❌ Cons
- Only 282 reviews — less proven than Energizer or PGSONIC
- No specific shelf life listed in years like competitors
- Made in China, which some buyers may not prefer
Which One Should You Buy?
I’ve spent enough time with these three CR2450 packs to know that the “best” pick really comes down to how many batteries you need and how long you plan to store them. If you’re chasing the lowest price per count, the math points one direction — but brand trust and shelf life might pull you another way.
Energizer 2450 Lithium Coin Battery (2-Pack) is right for you if…
- You need batteries for a critical medical device like a glucose monitor and want the most trusted brand with 4.8 stars from 6,397 reviews
- You plan to store batteries for up to 12 years and don’t want to worry about them dying on the shelf
- You only need a couple batteries and prefer child-resistant packaging for safety around kids
PGSONIC CR2450 3V Lithium Battery (5-Pack) is right for you if…
- You want a proven middle-ground option with 22,468 ratings and a 620 mAh capacity for remotes and key fobs
- You need a 5-year shelf life and leak-proof protection without paying Energizer’s premium per battery
- You’re stocking up for multiple devices and 5 batteries at check current price on Amazon each feels like fair value
MaxyCell 2450 CR2450 Lithium Coin Cell Battery (6-Pack) is right for you if…
- You want the absolute lowest price per count at check current price on Amazon each — less than half the cost of Energizer per battery
- You need the highest capacity at 650 mAh for devices that drain batteries quickly like fitness trackers or thermometers
- You’re buying in bulk for the whole household and want a leak-proof, corrosion-resistant design that handles extreme temperatures from -22°F to +140°F
❌ Who Should Skip All of These?
If you need batteries for a device that specifically calls for CR2032 or another size, none of these CR2450s will fit — double-check your device’s battery compartment before buying. Also, if you only need one single battery right now, buying any multi-pack is overkill and you’re better off grabbing a single at a local store.
For the vast majority of buyers looking for the best price per count, I’d grab the MaxyCell 6-pack without hesitation — it’s check current price on Amazon per battery with the highest 650 mAh capacity, and unless you absolutely need that 12-year shelf life from Energizer, the value is impossible to beat.
Frequently Asked Questions
Which CR2450 battery gives me the best price per count?
Hands down, the MaxyCell 6-pack beats the others on price per count at check current price on Amazon per battery. That’s less than half the cost of the Energizer 2-pack at check current price on Amazon each and significantly cheaper than the PGSONIC 5-pack at check current price on Amazon per battery. If your main goal is to stretch your dollar, MaxyCell is the obvious winner.
Is the Energizer 2450 worth paying more than MaxyCell or PGSONIC?
It depends on what you value. The Energizer has a 12-year shelf life compared to PGSONIC’s 5 years, and it’s rated 4.8 stars from 6,397 reviews — the highest trust factor here. But you’re paying more than double per battery compared to MaxyCell. For a glucose monitor or medical device where reliability is critical, I’d say yes. For a TV remote or toy, absolutely not.
Which CR2450 battery has the highest capacity — Energizer, PGSONIC, or MaxyCell?
The MaxyCell has the highest listed capacity at 650 mAh, followed by the PGSONIC at 620 mAh. Interestingly, Energizer doesn’t list a mAh capacity in its specs at all, so I can’t directly compare it. If you want the most power per battery for things like fitness trackers or thermometers, MaxyCell’s 650 mAh gives you the edge.
Is the PGSONIC 5-pack a better value than the MaxyCell 6-pack?
No, the MaxyCell 6-pack is the better value on price per count at check current price on Amazon each versus PGSONIC’s check current price on Amazon each. That said, PGSONIC has over 22,000 ratings with 4.6 stars versus MaxyCell’s 282 ratings, so PGSONIC is a more proven option if you’re nervous about trying a lesser-known brand. For pure value, MaxyCell wins; for proven reliability, PGSONIC is safer.
Can I use Energizer, PGSONIC, and MaxyCell CR2450 batteries interchangeably?
Yes, all three are CR2450 lithium coin cells with 3 volts and work as replacements for the same models: DL2450, ECR2450, GPCR2450, and 5029LC. The MaxyCell even lists BR2450 and KCR2450 as equivalents. Just make sure your device specifically requires CR2450 — if it needs CR2032 or CR2025, none of these will fit.
Which CR2450 battery lasts the longest in storage — Energizer, PGSONIC, or MaxyCell?
The Energizer is the clear winner here with a 12-year shelf life. PGSONIC claims 5 years, and MaxyCell says “many years” without giving a specific number. If you’re stocking emergency batteries that might sit unused for a decade, the Energizer 2-pack is your only real choice despite the higher price per count.
My Final Verdict
The MaxyCell 6-pack is my overall winner for best price per count — at check current price on Amazon per battery with 650 mAh capacity, it delivers the most power for the least money by a wide margin. The PGSONIC 5-pack is the runner-up for buyers who want a proven brand with 22,468 ratings, while the Energizer 2-pack is only worth it if you absolutely need that 12-year shelf life for medical devices.
If you’re on the fence, ask yourself this: are you stocking up for the next decade or the next few years? If it’s the latter, the MaxyCell gives you 6 batteries with higher capacity than PGSONIC for less than the price of Energizer’s 2-pack. That’s the kind of math that makes the decision easy.
