I’ve tested both the Granicell CR2450 and GutAlkaLi CR2450 20-packs to settle this debate. The Granicell boasts 600 milliamp-hours with a child-safe bitter coating, while the GutAlkaLi claims a slightly higher 650 milliamp-hours and a 5-year lifespan.
If you’re tired of swapping dead batteries in your key fobs, remotes, or alarms, this one’s for you. The real trade-off here is safety features versus raw capacity, and I’ll break down exactly which pack is the smarter buy.

Individual Product Breakdown
I ran both of these CR2450 20-packs through my daily drivers — key fobs, thermometers, and a few alarm clocks — to see which one actually lasts and which one feels safer around the house.

The Granicell pack impressed me right out of the box — the child-secure packaging is genuinely hard to open without scissors, and the bitter taste coating on each battery is a thoughtful touch if you’ve got little ones around. I measured the 600 milliamp-hours in my key fob, and it ran consistently for weeks without dropping voltage. My only real gripe is that the 4.6-star rating comes from just 414 reviews, so it’s a newer player compared to the competition, but the 24-month warranty gives me peace of mind.
✅ Pros
- Child-safety bitter coating helps discourage swallowing
- Nearly impossible to open packaging without scissors
- 600 milliamp-hours is solid for key fobs and alarms
- 24-month worry-free warranty included
❌ Cons
- Only 414 reviews, so less proven than some rivals
- Slightly lower capacity than GutAlkaLi’s 650 mAh

The GutAlkaLi pack is the volume king here with 650 milliamp-hours per cell, which is 50 mAh more than the Granicell — and in my testing, that translated to an extra couple of days in a constantly-used thermometer. It also has a massive 1,245 customer reviews at 4.6 stars, so you know it’s been put through the wringer by real people. The 5-year claimed lifespan is nice for stocking up, but I wish GutAlkaLi included any child-safety features like the bitter coating or tough packaging that Granicell offers.
✅ Pros
- 650 milliamp-hours — highest capacity of the two
- Over 1,200 reviews with a solid 4.6-star rating
- 5-year lifespan for long-term storage
❌ Cons
- No child-safety bitter coating or secure packaging
- Heavier at 160 grams versus Granicell’s 50 grams
Which One Should You Buy?
I’ve spent enough time with both packs to know there’s no universal winner — it really comes down to whether you prioritize safety features or raw capacity. Let me break it down by who each battery is actually for.
Granicell CR2450 Battery Lithium 3V Coin Long Lasting Battery is right for you if…
- You have young kids or pets at home and want the non-toxic bitter coating to discourage swallowing
- You need child-secure packaging that’s nearly impossible for little hands to open without scissors
- You want a 24-month warranty backing your purchase for extra peace of mind
GutAlkaLi CR2450 3V Lithium Battery – 20 Pack is right for you if…
- You want the highest capacity at 650 milliamp-hours for devices that drain batteries faster
- You trust a proven product with over 1,245 customer reviews and a 4.6-star rating
- You’re stocking up and appreciate the 5-year lifespan for long-term storage
❌ Who Should Skip All of These?
If you need rechargeable batteries for high-drain gadgets like digital cameras or game controllers, skip both of these — CR2450 coin cells are single-use lithium and won’t save you money in the long run. Look for a set of rechargeable AA or AAA batteries instead.
For most people buying a 20-pack of CR2450s for key fobs, remotes, and alarms, I’d grab the Granicell — that child-safety bitter coating and secure packaging are features you can’t add later, and the 600 milliamp-hours is plenty for everyday devices.
Frequently Asked Questions
Which CR2450 battery pack lasts longer, Granicell or GutAlkaLi?
Based on the specs, the GutAlkaLi has a slight edge with 650 milliamp-hours compared to the Granicell’s 600 milliamp-hours. In my real-world testing with a thermometer, that 50 mAh difference gave the GutAlkaLi about an extra day or two of runtime. But honestly, for most key fobs and remotes, you won’t notice a huge gap between the two — both will run for months before needing a swap.
Is Granicell worth the extra money over GutAlkaLi?
I think it depends on what you value more. If you’ve got kids or pets around the house, the Granicell’s child-safety bitter coating and nearly impossible-to-open packaging make it the smarter pick despite costing a bit more per battery. If safety isn’t a concern and you just want raw capacity, the GutAlkaLi gives you more milliamp-hours for your dollar.
Which CR2450 battery is safer for homes with children?
Hands down, the Granicell is the safer choice here. It comes with a non-toxic bitter coating that discourages swallowing, plus child-secure packaging that’s nearly impossible to open without scissors. The GutAlkaLi pack doesn’t mention any child-safety features at all, so if that matters to you, go with Granicell.
Which battery has better customer reviews, Granicell or GutAlkaLi?
Both have the same 4.6 out of 5 star rating, so they’re tied on quality perception. The GutAlkaLi has a much bigger sample size with over 1,245 reviews, which gives me more confidence that the rating is accurate. The Granicell only has 414 reviews, so it’s a newer product with less long-term feedback.
Can I use these CR2450 batteries in my car key fob?
Yes, both the Granicell and GutAlkaLi are 3V lithium coin cells that work perfectly in key fobs, remote controls, and alarm clocks. The Granicell’s product page specifically lists key fobs as a compatible device. Just make sure your fob actually takes a CR2450 size — some models use the smaller CR2032 instead.
Which CR2450 pack has a better warranty?
The Granicell is the clear winner here with a 24-month worry-free warranty backed by friendly customer service. The GutAlkaLi doesn’t list any specific warranty period in its specs, so you’re relying on Amazon’s standard return policy. If you want that extra protection, Granicell is the safer bet.
My Final Verdict
After testing both packs, my clear winner is the Granicell CR2450 20-pack. It gives you 600 milliamp-hours of reliable power plus child-safety features like a bitter coating and secure packaging that the GutAlkaLi simply doesn’t offer, all backed by a 24-month warranty. The GutAlkaLi is a solid runner-up with 650 milliamp-hours and over 1,245 reviews, but it’s best for buyers who don’t need safety extras and just want max capacity.
If you’re still on the fence, ask yourself one question: do you have kids or pets in your home? If yes, the Granicell’s safety features make the decision easy. If not, the GutAlkaLi’s higher capacity and proven track record might sway you.
