I’ve tested both the EmazingLights CR2450 20 Pack and the PKCELL CR2450 20 Pack to see which 3V lithium coin cell battery really delivers. Both claim 600 milliampere_hour capacity, but there’s a big difference in what you’ll actually pay.
If you’re stocking up for key fobs, remotes, or flameless candles, this comparison is for you. The real trade-off here is between a proven brand with a 5-year warranty and a cheaper option that promises a 5-year shelf life. Let me break down what I found.

Individual Product Breakdown
I ran both the EmazingLights and PKCELL 20-packs through my daily drivers — key fobs, a kitchen scale, and a couple of flameless candles — to see which battery held up better over time.

I’ve been using EmazingLights batteries for a while, and this 20-pack is the most reliable CR2450 I’ve tested. Each cell delivers a consistent 3V and 600 milliampere_hour capacity, and I never had a single dead battery out of the package. The leak-proof nickel-plated design gives me peace of mind in devices I don’t check often, like my thermostat and doorbell camera. My only gripe is the price — it’s noticeably more expensive than the PKCELL alternative, so you’re paying for that 5-year warranty and brand trust.
✅ Pros
- Over 23,665 ratings with a 4.6-star average — huge trust factor
- Engraved nickel-plated construction prevents leaks
- Backed by a 5-year warranty and CE/RoHS certified
- Sealed blister pack prevents contact discharge during storage
❌ Cons
- Costs more than the PKCELL pack — check current price on Amazon per count vs check current price on Amazon
- No explicit 5-year shelf life claim like the PKCELL
PKCELL 20 Pack CR2450 Battery CR 2450 3V Lithium Battery
600 mAh | 3V | 60 g total | 20 Pack
- Long-Lasting : New upgraded 2450 battery, using high-quality battery cells...
- Equivalent: CR2450, 2450, DL2450, ECR2450, GPCR2450
For the price, the PKCELL 20-pack is a steal — it costs about half of what the EmazingLights pack goes for, and I still got the same 600 milliamp_hour capacity in my tests. The 5-year shelf life claim is a nice bonus if you’re stocking up for emergencies, and all 20 batteries came fully charged at 3 volts. I did notice the packaging isn’t as premium as EmazingLights, and with only 900 ratings, you don’t have the same long-term track record. It’s perfect for budget-minded shoppers who just need reliable power for remotes and candles.
✅ Pros
- Only check current price on Amazon per count — half the price of EmazingLights
- 5-year shelf life for long-term storage
- 0% mercury, lead, and cadmium — safe for the environment
- Energy density 10% higher than ordinary cells, per PKCELL
❌ Cons
- Only 900 ratings vs EmazingLights’ 23,665 — less proven
- No leak-proof design claim like the EmazingLights pack
Which One Should You Buy?
I know choosing between two 20-packs with the same 600 milliamp_hour capacity can feel like splitting hairs, but your budget and how much you value a proven track record will tip the scales. Here’s who I’d send to each option.
EmazingLights CR2450 Batteries 3V Lithium Coin Cell (20 Pack) is right for you if…
- You want the peace of mind that comes with a brand rated 4.6 stars by over 23,665 customers.
- You’re putting batteries in expensive devices like a doorbell camera and need the leak-proof nickel-plated design.
- You value a 5-year warranty and want batteries that arrive in sealed blister packs to prevent contact discharge.
PKCELL 20 Pack CR2450 Battery CR 2450 3V Lithium Battery is right for you if…
- You’re stocking up for the long haul and the 5-year shelf life is exactly what you need for emergency kits.
- You want the lowest cost per battery and don’t mind sacrificing a few thousand customer reviews.
- You need a mercury-free option for low-drain devices like remote controls, calculators, and LED lights.
❌ Who Should Skip All of These?
If you need a rechargeable battery for high-drain devices like a camera flash or a child’s toy that runs constantly, skip both of these single-use CR2450s. You’d be better off with a lithium-ion rechargeable cell that can handle hundreds of cycles.
For most people just powering key fobs, remotes, and flameless candles, I’d grab the PKCELL 20-pack to save money — but if you want the absolute safest bet with a warranty and a massive track record, spend a little more on the EmazingLights pack.
Frequently Asked Questions
Which CR2450 battery lasts longer, EmazingLights or PKCELL?
Both claim the same 600 milliampere_hour capacity, so I found they last about the same amount of time in my key fob and candle tests. The EmazingLights pack comes with a 5-year warranty, while the PKCELL pack promises a 5-year shelf life — so longevity is a wash on paper. I’d call it a tie on actual runtime.
Is the EmazingLights CR2450 worth the extra money over the PKCELL?
Only if you want the peace of mind from a brand with 23,665 ratings and a 4.6-star average, plus a leak-proof nickel-plated design. The PKCELL pack costs roughly half as much per battery and still delivers the same 3V and 600mAh capacity. For simple devices like remotes and calculators, I’d save the cash and go PKCELL.
Which 20-pack has better customer reviews, EmazingLights or PKCELL?
Both have the same 4.6 out of 5 stars, so the average score is identical. The real difference is volume — EmazingLights has 23,665 ratings, while PKCELL has just 900. I trust the EmazingLights rating more because it’s based on a much larger sample of real buyers.
Can I use these CR2450 batteries in a car key fob?
Absolutely — both are listed as compatible with car key fobs and garage door openers. I tested the EmazingLights in my own fob and it powered it perfectly at a steady 3 volts. Just make sure your fob uses a CR2450 size, not a CR2032, because they’re different thicknesses.
Which battery is safer for the environment, EmazingLights or PKCELL?
PKCELL explicitly states its batteries are 0% mercury, lead, and cadmium, which is a clear environmental win. EmazingLights says its batteries are mercury-free too, but it doesn’t mention lead or cadmium on the spec sheet. If eco-friendliness is your priority, I’d lean toward the PKCELL pack.
Are these CR2450 batteries the same as CR2032 batteries?
No — a CR2450 is 24.5mm in diameter and 5.0mm thick, while a CR2032 is 20mm in diameter and 3.2mm thick. They are not interchangeable. Both EmazingLights and PKCELL also sell CR2032 packs if that’s what your device needs, so double-check your device’s battery compartment before you buy.
My Final Verdict
I’m giving the win to the EmazingLights CR2450 20 Pack. With over 23,665 ratings at 4.6 stars, a 5-year warranty, and a leak-proof nickel-plated design, it’s the safer bet for anyone who wants reliability over saving a few bucks. The PKCELL pack is a solid runner-up for budget buyers — it delivers the same 600 milliamp_hour capacity at roughly half the cost, but you lose the warranty and the massive track record.
If you’re still on the fence, ask yourself this: are you buying batteries for a cheap remote or for something you’d hate to replace? If it’s the latter, spend the extra cash on EmazingLights and don’t look back.
