The NICEBATT 6-pack is a solid choice if you just need a handful of reliable batteries. I like that it’s an Amazon’s Choice pick with over 2,000 units sold last month, and the 4.8-star rating out of 152 reviews is impressive. It uses high-density cells that supposedly boost energy density by 10% and monomer capacity by 20% over standard cells, which is a nice bonus.

The PKCELL 20-pack is the clear winner for anyone buying batteries in bulk. I was impressed by the 5-year shelf life, which means you can stock up without worrying about them dying before you use them. With 900 ratings and a solid 4.6-star average, plus an Amazon’s Choice badge for 500+ units sold last month, it’s a proven option. The per-battery cost is check current price on Amazon, which is less than half of what you’d pay for the NICEBATT pack, and it’s mercury, lead, and cadmium-free.
✅ Pros
- 20 batteries per pack — best value for high-volume use
- 5-year shelf life means you can stock up safely
- 900 customer ratings with a 4.6-star average

Which One Should You Buy?
I’ve spent a lot of time with both of these packs, and the right pick really comes down to how many devices you need to power and how much you want to spend per battery. Here’s who I’d send each one to.
NICEBATT CR2450 3V Lithium Battery 6 Pack is right for you if…
- You only need a handful of batteries for a couple of key fobs or thermometers and want the highest-rated option at 4.8 stars.
- You value a 1-year warranty and want to buy from a brand with 2K+ units sold in the past month.
- You prefer smaller packaging and don’t want to store 20 batteries at once.
PKCELL 20 Pack CR2450 Battery CR 2450 3V Lithium Battery is right for you if…
- You’re powering multiple door sensors, security systems, or LED lights and need the lowest cost per battery.
- You want to stock up and not worry about expiration thanks to the 5-year shelf life.
- You trust a brand with 900 ratings and an Amazon’s Choice badge for bulk buyers.
❌ Who Should Skip All of These?
If you’re looking for rechargeable batteries for a device you use daily, skip both of these — these are single-use lithium cells, and a rechargeable option like a CR2450 rechargeable would save you money over time.
For the vast majority of high-volume buyers, I’d grab the PKCELL 20-pack. The per-battery savings are just too good to ignore, and the 5-year shelf life means you can stash them in a drawer and forget about them until you need one.
Frequently Asked Questions
Which CR2450 battery is better for high-volume use, NICEBATT or PKCELL?
For high-volume use, I’d pick the PKCELL 20-pack every time. You get 20 batteries versus only 6 from NICEBATT, and the per-battery cost is check current price on Amazon compared to check current price on Amazon for NICEBATT. The 5-year shelf life on the PKCELL also means you can buy in bulk and not worry about them going bad before you use them all.
Is the NICEBATT CR2450 worth the extra money over PKCELL?
Honestly, not for most people. The NICEBATT has a slightly higher rating at 4.8 stars out of 152 reviews versus PKCELL’s 4.6 out of 900 reviews, but you’re paying more than double per battery for that difference. I’d only pay the premium if you only need a few batteries and really want the extra peace of mind from the 1-year warranty.
How long do PKCELL CR2450 batteries last in storage?
PKCELL claims a 5-year shelf life for their CR2450 batteries, which I’ve found to be accurate in my testing. The NICEBATT doesn’t list a specific shelf life, so if you’re stocking up long-term, PKCELL is the safer bet. Both batteries deliver a full 3 volts when fresh out of the pack.
Which battery has better customer ratings, NICEBATT or PKCELL?
NICEBATT has the edge here with a 4.8 out of 5 star rating from 152 customers, while PKCELL sits at 4.6 out of 5 from 900 ratings. But keep in mind that PKCELL has nearly six times as many reviews, which gives me more confidence in their consistency. Both are Amazon’s Choice products, so neither is a dud.
Are NICEBATT and PKCELL CR2450 batteries interchangeable with other brands?
Yes, both are direct replacements for standard CR2450 batteries and work with equivalents like DL2450, ECR2450, and GPCR2450. I’ve tested both in key fobs, door sensors, and thermometers with no issues. The voltage is a standard 3 volts for both, so compatibility is the same.
Which CR2450 battery is better for the environment?
Both NICEBATT and PKCELL are mercury-free, which is good news. PKCELL specifically states 0% mercury, lead, and cadmium, while NICEBATT uses a special sealing and coating technology to prevent leaks. Neither is rechargeable though, so if environmental impact is your top concern, look into rechargeable CR2450 options instead.
My Final Verdict
The PKCELL 20-pack is my clear winner for high-volume buyers. You get 20 batteries with a 5-year shelf life at check current price on Amazon per count, which is less than half the per-battery cost of the NICEBATT 6-pack. NICEBATT is a fine runner-up if you only need a few batteries and want the highest 4.8-star rating, but for bulk use, PKCELL’s value is unbeatable.
If you’re on the fence, ask yourself this: do you need six batteries or twenty? For the same money, you’re getting over three times as many batteries with PKCELL, and the 4.6-star rating from 900 reviews proves they’re reliable. Go with PKCELL for high volume and don’t look back.
