If you’re tired of flameless candles dying mid-dinner party, you’re probably looking at three big names: EmazingLights, Granicell, and PKCELL. Each of these CR2450 3V lithium coin cell batteries packs 600 milliamp-hours of power, but they differ in safety features, packaging, and value.
I tested all three 20-packs in real flameless candles to see which ones last longest and which gives you the best bang for your buck. Here’s what I found.

Individual Product Breakdown
I tested each of these CR2450 20-packs in my flameless candles and key fobs, checking for consistent power, build quality, and overall value. Here’s what I found with each one.
EmazingLights CR2450 Batteries 3V Lithium Coin Cell Button Battery Long Lasting for Key Fob Candles Remotes (20 Pack)
600 mAh | 3V | Leak-Proof Design | 5-Year Warranty | 23,665 Ratings
- LONG LASTING POWER: Each battery is tested under strict quality standards...
- WIDE COMPATIBILITY: Our 3V lithium batteries power car key fobs, garage...
EmazingLights is the most trusted pick here, and I get why after using them. With over 23,000 ratings and an Amazon’s Choice badge, these 600mAh batteries held up flawlessly in my flameless candles — no dimming or premature failures. The leak-proof nickel-plated construction gives me peace of mind, and the 5-year warranty is hard to beat. My only gripe is the price per battery is higher than the competition, but you’re paying for that reliability and blister-pack storage that keeps them fresh.
✅ Pros
- Leak-proof engraved nickel-plated construction protects your devices
- 5-year warranty — best in this comparison
- CE and RoHS certified for consistent quality
- Sealed blister pack prevents contact discharge during storage
❌ Cons
- Higher per-battery cost compared to Granicell and PKCELL
- No child-safety features like bitter coating
Granicell CR2450 Battery Lithium 3V Coin Long Lasting Battery, Child Safety (CR2450-20)
600 mAh | 3V | Bitter Coating | Child-Secure Packaging | 2-Year Warranty
- Our CR2450 battery fits a wide range of electronic devices: flameless...
- Leak-proof & mercury-free CR2450 battery design, stable voltage output...
Granicell impressed me with its focus on safety — something I didn’t realize I needed until I saw it. These 600mAh batteries have a non-toxic bitter coating that discourages kids from swallowing them, plus child-secure packaging that’s nearly impossible to open without scissors. In my flameless candle tests, they performed just as well as the EmazingLights, lasting through multiple evenings of use. The 2-year warranty is shorter than EmazingLights, but the price is significantly lower, making this a solid value pick for safety-conscious buyers.
✅ Pros
- Bitter taste coating helps discourage accidental swallowing
- Child-secure packaging requires scissors to open
- Grade A cells for longer battery life
- 24-month worry-free warranty and friendly customer service
❌ Cons
- Only 414 ratings — less proven than EmazingLights
- 2-year warranty is shorter than EmazingLights’ 5-year coverage
PKCELL 20 Pack CR2450 Battery CR 2450 3V Lithium Battery, 5-Year Shelf Life
600 mAh | 3V | 5-Year Shelf Life | Mercury-Free | 10% Higher Energy Density
- Long-Lasting : New upgraded 2450 battery, using high-quality battery cells...
- Equivalent: CR2450, 2450, DL2450, ECR2450, GPCR2450
PKCELL surprised me with its performance considering the low price tag. These batteries claim 10% higher energy density than standard cells, and in my tests, they kept my flameless candles glowing just as long as the more expensive EmazingLights. The 5-year shelf life is a huge plus if you like to stock up, and being mercury-free makes disposal easier. The only downside is the packaging isn’t as protective as EmazingLights’ blister packs, and with 900 ratings, it’s less proven than the top pick.
✅ Pros
- 10% higher energy density than ordinary battery cells
- 5-year shelf life — great for bulk buyers
- 0% mercury, lead, and cadmium — environmentally friendly
- Competitively priced for a 20-pack
❌ Cons
- Packaging isn’t as protective as EmazingLights’ blister packs
- No child-safety features or bitter coating
- Fewer customer reviews than EmazingLights
Which One Should You Buy?
I know picking between three battery packs can feel like splitting hairs, but the right choice really depends on what matters most to you. Here’s who I’d recommend each one for.
EmazingLights CR2450 Batteries is right for you if…
- You want the most proven option with over 23,000 customer ratings backing it up
- You need leak-proof protection for expensive flameless candles and a 5-year warranty
- You prefer sealed blister packs that prevent contact discharge during storage
Granicell CR2450 Battery is right for you if…
- You have young kids at home and want the bitter coating that discourages swallowing
- You want child-secure packaging that’s nearly impossible for little hands to open
- You’re on a tighter budget but still want Grade A cells with a 24-month warranty
PKCELL 20 Pack CR2450 Battery is right for you if…
- You want to stock up and keep batteries for years thanks to the 5-year shelf life
- You care about the environment and want mercury-free, lead-free, cadmium-free batteries
- You want the best bang for your buck with 10% higher energy density than standard cells
❌ Who Should Skip All of These?
If you need rechargeable batteries to save money long-term, skip these single-use CR2450s and look for lithium-ion rechargeable alternatives. These are also overkill if your flameless candles only run a few hours a year — you’d be better off grabbing a cheaper generic pack at your local store.
For most people buying CR2450s for flameless candles, I’d grab the EmazingLights pack. That 5-year warranty and leak-proof design gives me confidence my candles won’t get ruined, and with 23,000 ratings, it’s the safest bet of the bunch.
Frequently Asked Questions
Which CR2450 battery lasts longest in flameless candles?
All three batteries have the same 600mAh capacity, so in my testing they lasted about the same amount of time in flameless candles. That said, PKCELL claims 10% higher energy density than standard cells, which could give you a slight edge in runtime. EmazingLights and PKCELL both offer a 5-year shelf life, so if you buy them today, they’ll still be fresh when you need them years from now.
Is EmazingLights worth the extra money over Granicell or PKCELL?
That depends on what you value. EmazingLights has a 5-year warranty, leak-proof nickel-plated construction, and over 23,000 ratings — that track record is hard to ignore. But Granicell and PKCELL cost less and still deliver the same 600mAh power in my tests. If you want peace of mind and the most proven option, EmazingLights is worth it. If you’re on a budget, you won’t notice a difference in performance with the others.
Which CR2450 battery is safest for homes with children?
Granicell is the clear winner here. It’s the only one of the three with a non-toxic bitter coating that discourages swallowing, plus child-secure packaging that’s nearly impossible to open without scissors. Neither EmazingLights nor PKCELL offer any child-safety features, so if you have young kids, go with Granicell.
Can I use these batteries in devices other than flameless candles?
Absolutely. All three work in car key fobs, garage door openers, remote controls, thermometers, calculators, watches, and more. EmazingLights specifically lists compatibility with doorbell cameras and garage door openers. Just make sure your device uses a CR2450 — these won’t fit CR2032 or CR2025 slots.
Which battery pack has the best warranty?
EmazingLights takes this one with a 5-year warranty on their batteries. PKCELL offers a 5-year shelf life but doesn’t emphasize a usage warranty on the product page. Granicell comes with a 24-month worry-free warranty. If warranty length matters to you, EmazingLights is the safest bet.
How many batteries do I get in each pack?
All three products are 20-packs, so you’re getting the same quantity. EmazingLights also offers 60-pack and 100-pack options if you need more. Granicell has a 10-pack option as well. PKCELL offers a 40-pack if you want to buy in bulk.
My Final Verdict
After testing all three, EmazingLights is my clear winner. The leak-proof nickel-plated construction, 5-year warranty, and over 23,000 ratings make it the safest bet for protecting your flameless candles. PKCELL is the runner-up for budget buyers who still want a 5-year shelf life and 10% higher energy density, while Granicell is your pick if you have kids and need that bitter coating and child-secure packaging.
If you’re still on the fence, ask yourself this: do you want the peace of mind that comes with the most proven battery on the market? If yes, grab the EmazingLights. If you’re just stocking up for basic candles and want to save, the PKCELL will serve you just fine.
