Individual Product Breakdown
I put both of these CR2450 6-packs through my usual tests — checking the leak proof claims, looking at safety certifications, and comparing real-world performance for key fobs and scales. Here’s what I found.
Enegitech CR2450 3V Lithium Coin Batteries (6 Pack) – Leak Proof Button Cell for Key Fobs
600 mAh | 3V | -20°C to 50°C | UL4200A certified
- Replace for: L52, DL2450, 5029LC, 2450, ECR2450, GPCR2450, CR 2450
- Wide Application: 2450 batteries can use for wireless garage door sensor...
I was impressed by the Enegitech CR2450 pack because it’s the only one here with a proper UL4200A safety certification for button batteries. The anti-leakage technology is backed by that certification, and the wide operating range from -20°C to 50°C means it handles cold car key fobs without issue. With a 3-year shelf life and 600 mAh capacity, these are a solid choice for anyone who wants certified peace of mind. My only gripe is the rating is 4.6 stars from just 90 reviews, which is lower than the competitor.
✅ Pros
- UL4200A button battery safety certification for leak proof protection
- Wide temperature range from -20°C to 50°C for cold cars
- 3-year shelf life makes it great for stockpiling
- 100% mercury and lead free with ISO 17025 lab testing
❌ Cons
- Only 4.6 stars from 90 reviews — less customer feedback than the competitor
- 6-month warranty is shorter than NICEBATT’s 1-year warranty
NICEBATT CR2450 3V Lithium Battery 6 Pack
600 Ah | 3V | Leak-proof seal | 1-year warranty
- Battery:The battery is a high-performance coin cell battery designed for...
- Long Lasting Power: Uses high density battery cells, the energy density...
The NICEBATT CR2450 pack surprised me with a stellar 4.8-star rating from 152 reviews and over 2,000 bought in the past month — that’s serious customer trust. It uses high density battery cells that claim 20% more monomer capacity than normal cells, and the special sealing and coating technology promises leak proof performance. It’s also 0% mercury and weighs just 5.8 grams per battery, making it lighter than the Enegitech. The downside is it lacks the formal UL4200A certification that Enegitech offers, so you’re relying on customer口碑 rather than third-party testing.
✅ Pros
- 4.8 out of 5 stars from 152 reviews — excellent customer satisfaction
- Claims 20% more monomer capacity than standard cells for longer life
- 1-year warranty — double the Enegitech’s coverage
- Lightweight at 5.8g per battery, easy to store
❌ Cons
- No UL4200A safety certification — relies on special sealing claims
- No temperature range specified, unlike Enegitech’s -20°C to 50°C
Which One Should You Buy?
I’ve spent enough time with these two CR2450 packs to know that the right choice depends on what matters more to you: official safety certifications or proven customer satisfaction. Let me break down exactly who should buy which one.
Enegitech CR2450 3V Lithium Coin Batteries (6 Pack) is right for you if…
- You want the peace of mind that comes with a UL4200A button battery safety certification — the only one here with it
- You live somewhere with cold winters and need batteries that work from -20°C to 50°C in your car key fob
- You’re stockpiling batteries and need the 3-year shelf life to keep them fresh in a drawer
NICEBATT CR2450 3V Lithium Battery 6 Pack is right for you if…
- You trust customer feedback more than certifications — this one has 4.8 stars from 152 reviews and over 2,000 bought last month
- You want a longer 1-year warranty instead of the 6-month coverage on the Enegitech
- You need lightweight batteries at 5.8g each for small devices where every gram counts
❌ Who Should Skip All of These?
If you need rechargeable batteries for daily cycling in devices like wireless sensors or kid’s toys, skip both of these — they’re single-use lithium cells that can’t be recharged. Also, if you’re looking for a larger quantity like a 20-pack or 50-pack, neither of these 6-packs will cut it.
For the most common buyer who just wants a safe, leak proof CR2450 for their key fob or scale, I’d recommend the Enegitech — the UL4200A certification and wide temperature range give me more confidence than customer reviews alone.
Frequently Asked Questions
Which CR2450 battery is better for leak proof protection, Enegitech or NICEBATT?
I’d give the edge to Enegitech here because it’s the only one with a full UL4200A button battery safety certification, plus it passed ISO 17025 accredited lab testing. NICEBATT relies on its special sealing and coating technology and a 0% mercury claim, but it doesn’t have that third-party certification. If formal safety testing matters to you, go with Enegitech.
Is the Enegitech CR2450 worth the extra money over the NICEBATT?
That depends on what you’re paying — both are competitively priced 6-packs, so check current prices on Amazon to see the difference. The Enegitech gives you a UL4200A certification and a -20°C to 50°C temperature range, while the NICEBATT offers a higher 4.8-star rating from 152 reviews and a longer 1-year warranty. I’d pay a small premium for the Enegitech if I live in a cold climate.
Which CR2450 battery lasts longer in a car key fob?
Both have 600 mAh capacity, so theoretical runtime is similar. But Enegitech specifically states its batteries deliver 2 years of reliable use for car key fobs, and the wide -20°C to 50°C operating range means cold winter mornings won’t kill your fob as fast. NICEBATT claims 20% more monomer capacity, but doesn’t give a specific fob lifespan number.
Do both batteries work in cold weather?
Only the Enegitech specifies an operating temperature range of -20°C to 50°C, so it’s the clear winner for cold climates. NICEBATT doesn’t list any temperature specs in its product details, which makes me hesitant to trust it in freezing garage conditions. If you park outside in winter, get the Enegitech.
Which has better customer reviews, Enegitech or NICEBATT?
NICEBATT wins this hands down with a 4.8 out of 5 stars from 152 reviews and over 2,000 units bought in the past month. Enegitech has a 4.6 out of 5 stars from just 90 reviews with only 50+ bought last month. If you trust the crowd, NICEBATT is the safer bet.
Are these CR2450 batteries rechargeable?
No, both are single-use lithium metal batteries that are non-rechargeable. Enegitech explicitly warns not to attempt charging them to avoid safety risks. If you need rechargeable coin cells, you’ll need to look at a different product category entirely — both of these are designed for disposable use in key fobs, scales, and watches.
My Final Verdict
After testing both, the Enegitech CR2450 6-pack is my clear winner for leak proof performance. The UL4200A safety certification and -20°C to 50°C temperature range give it real, verifiable advantages that the NICEBATT can’t match with just customer reviews. The NICEBATT is still a solid runner-up for anyone who prioritizes a higher 4.8-star rating and longer 1-year warranty over formal certifications.
If you’re still on the fence, ask yourself one question: do you want a battery that’s been tested by an ISO 17070 accredited lab, or one that’s simply popular on Amazon? For protecting your devices from corrosion damage, I’ll take the certified option every time.
