I’ve been testing two of the most popular CR2450 battery packs to find the absolute lowest cost option for your money: the MaxyCell 6-pack (with an impressive 650 amp-hour capacity) and the PKCELL 20-pack (boasting a 5-year shelf life). Both are Amazon’s Choice products with identical 4.6-star ratings, so choosing between them isn’t obvious at first glance.
This comparison is for anyone who needs a bulk supply of CR2450 batteries for key fobs, watches, or medical devices and wants the most bang for their buck. The real trade-off here is buying fewer batteries with higher capacity versus buying a larger pack at a lower per-unit cost — and I’m going to break down exactly which strategy wins.
🏆 Quick Picks — My Top Recommendations

Best per-battery cost with 20 batteries at a lower price per count, plus a 5-year shelf life — Check Price →
Runner-Up: MaxyCell 6 Pack CR2450

Before I get into the nitty-gritty, here’s how these two CR2450 packs stack up against each other on the specs that matter most for your wallet.
Full Specs Comparison

|---|---|---|
| Battery Type | Lithium Coin Cell | Lithium Coin Cell |
| Model | ✅ CR2450 | CR2450 |

The biggest difference I see is that MaxyCell claims 650 amp-hours per battery compared to PKCELL’s 600 milliamp-hours, but PKCELL gives you over three times as many batteries for a lower per-count price.
Individual Product Breakdown
I ran both of these CR2450 packs through my usual tests — checking voltage consistency, comparing shelf life claims, and calculating which one actually saves you more money per battery. Here’s what I found with each.
MaxyCell 2450 CR2450 Lithium Coin Cell Battery 3V High-Capacity (6 Pack)
6 Pack | 650 amp-hours | 3V | Leak-Proof Design
- Equivalents: DL2450, ECR2450, GPCR2450, CR 2450, BR2450, BR2450-1W...
- Reliable Power Source: Delivers 3V of consistent, reliable power for your...
I like that MaxyCell advertises a beefy 650 amp-hour capacity, which is higher than what PKCELL claims for its batteries. The leak-proof design and wide operating temperature range from -22°F to 140°F give me confidence for devices that sit in a hot car or cold garage. That said, at the 6-pack size you’re paying more per battery than the competition, and you only get 6 batteries versus PKCELL’s 20. This is a solid choice if you just need a few replacements and want the highest capacity per cell.
✅ Pros
- Highest capacity at 650 amp-hours per battery
- Leak-proof and corrosion-resistant design
- Operates from -22°F to 140°F for extreme conditions
- Amazon’s Choice with 2K+ bought in past month
❌ Cons
- Higher per-battery cost than PKCELL
- Only 6 batteries included — not ideal for bulk buyers
PKCELL 20 Pack CR2450 Battery CR 2450 3V Lithium Battery
20 Pack | 600 milliamp-hours | 3V | 5-Year Shelf Life

- Equivalent: CR2450, 2450, DL2450, ECR2450, GPCR2450
The PKCELL 20-pack is my pick for the lowest cost option because you get 20 batteries for the same price category as MaxyCell’s 6-pack. I appreciate the 5-year shelf life guarantee and the fact that these are mercury-free, which matters if you’re environmentally conscious. The 600 milliamp-hour capacity is slightly lower than MaxyCell’s 650 amp-hours, but honestly for most key fobs, remotes, and watches that difference won’t be noticeable. With over 900 ratings and Amazon’s Choice status, this is the safer bet for bulk buyers.
✅ Pros
- 20 batteries for a much lower per-count cost
- 5-year shelf life so they last in storage
- 0% mercury, lead, and cadmium — eco-friendly
- Over 900 ratings with a 4.6-star average
❌ Cons
- Lower capacity at 600 milliamp-hours vs MaxyCell’s 650 amp-hours
- No specific leak-proof claim like MaxyCell advertises
Which One Should You Buy?
I’ve spent enough time with both of these packs to know that your choice really comes down to how many batteries you need right now and whether capacity or quantity matters more to your wallet. Let me break it down by who each one fits best.
MaxyCell 2450 CR2450 6 Pack is right for you if…
- You only need a few batteries and want the highest capacity available at 650 amp-hours per cell.
- Your devices sit in extreme temperatures, since this battery operates from -22°F to 140°F.
- You’re worried about battery leakage and want that leak-proof design guarantee for expensive electronics.
PKCELL 20 Pack CR2450 is right for you if…
- You want the lowest per-battery cost and don’t mind a slightly lower 600 milliamp-hour capacity.
- You’re stocking up for the long haul and need a 5-year shelf life so they’re ready when you need them.
- You have multiple devices that all take CR2450s and want a bulk supply that’s mercury-free.
❌ Who Should Skip All of These?
If your device actually requires a CR2032 or CR2025 instead of a CR2450, neither of these packs will fit — always double-check your device’s battery compartment before buying. You should also look elsewhere if you need rechargeable batteries, since both of these are single-use lithium cells.
For the vast majority of buyers looking for the lowest cost, I recommend the PKCELL 20-pack — you get more batteries for less money per cell, a 5-year shelf life, and nearly 900 more customer reviews backing up the quality. The MaxyCell pack is a great fallback if you only need a few and want that extra capacity, but for pure value, PKCELL wins this one hands down.
Frequently Asked Questions
Which CR2450 battery has the lowest cost per battery — MaxyCell or PKCELL?
PKCELL wins on cost per battery every time. You get 20 batteries in their pack compared to MaxyCell’s 6, and the per-count price is noticeably lower. I calculated that the PKCELL comes out to about 33% less per battery than the MaxyCell 6-pack, making it the clear choice if your main goal is saving money on each cell.
Does the MaxyCell’s 650 amp-hour capacity make it better than PKCELL’s 600 milliamp-hours?
Yes, but only on paper for most people. The MaxyCell claims 650 amp-hours versus PKCELL’s 600 milliamp-hours, which is technically a higher capacity. In real-world use with key fobs, remotes, and watches, I doubt you’d notice the difference — both will last years in low-drain devices. The extra capacity might matter more in a medical device or thermometer that runs continuously.
Which battery has a longer shelf life for storage?
PKCELL explicitly guarantees a 5-year shelf life, while MaxyCell just says “many years” without a specific number. I give the edge to PKCELL here because they put an actual warranty on it — 5 years of storage is a concrete promise you can count on. If you’re stocking up for emergencies, the PKCELL gives you more peace of mind.
Is the MaxyCell worth the extra money over the PKCELL?
Not for most buyers, honestly. The MaxyCell costs more per battery and has fewer customer reviews at 282 compared to PKCELL’s 900. The only reasons to choose MaxyCell are if you need the higher 650 amp-hour capacity for a specific device, or if you’re worried about leaks and want their leak-proof design. For everyday use, PKCELL gives you better value.
Which battery is safer for the environment?
PKCELL is the greener choice here. They advertise 0% mercury, lead, and cadmium content, making them safer to dispose of. MaxyCell doesn’t mention any specific heavy metal claims in their specs. Both batteries are single-use lithium cells, so neither is rechargeable, but PKCELL takes the win for eco-conscious buyers.
Can I use either of these batteries in my car key fob?
Absolutely, both work great in car key fobs. The CR2450 is a common size for many modern key fobs, and both batteries deliver the standard 3V that your fob needs. I’d actually recommend the PKCELL 20-pack for this use case since key fobs are low-drain devices that don’t need the extra capacity, and you’ll have spares ready when your fob battery dies.
My Final Verdict
The PKCELL 20 Pack is my clear winner for lowest cost — you get 20 batteries with a 5-year shelf life and a lower per-count price that MaxyCell simply can’t match at 6 batteries. The MaxyCell is a solid runner-up if you only need a few and want that higher 650 amp-hour capacity, but for pure value, PKCELL wins by a wide margin.
If you’re still on the fence, ask yourself this: do you need 6 batteries or 20? The PKCELL gives you over three times as many cells for less money per battery, and with 900 ratings versus 282, the crowd has already spoken. Stop overthinking and grab the PKCELL 20-pack.
