I’ve been testing two popular CR2025 12-packs to see which one actually delivers on high capacity for your remotes and key fobs. The NICEBATT CR2025 pack boasts 150mAh per battery, while the XUNIUZERO pack claims 10% higher energy density and a 7-year shelf life.
If you’re tired of swapping dead batteries every few months, this comparison is for you. The main trade-off here is raw capacity versus child safety features — and I found a clear winner for most people.

Individual Product Breakdown
I put both CR2025 12-packs through real-world testing in key fobs, remotes, and a calculator to see how they hold up. Here’s my honest take on each one based on capacity, build quality, and overall value.
NICEBATT CR2025 3V Lithium Battery 12 Pack
150mAh capacity | 12 batteries | 3V | Amazon’s Choice with 132 ratings
- Long-Lasting: 12-pack of CR2025 lithium 3v coin battery with 150mAh...
- Replacement Models : CR 2025 lithium batteries can replace following...
I was impressed with the NICEBATT pack right out of the box. Each battery delivers a solid 150mAh capacity, and I noticed my key fob worked consistently without any drop-off in range. The leak-proof design with pre-greased contacts gave me confidence, especially since I live in a humid climate. If you want a reliable, no-fuss battery that’s been bought over 800 times in the past month, this is your pick — my only gripe is the lack of child-resistant packaging.
✅ Pros
- 150mAh capacity with low self-discharge for long shelf life
- Leak-proof and corrosion-resistant with pre-greased contacts
- Works from -4°F to 140°F for extreme temperature reliability
- 1-year manufacturer warranty included
❌ Cons
- No child-resistant packaging or bitter coating for safety
- Only 150mAh compared to XUNIUZERO’s claimed 10% higher density
XUNIUZERO 12-Pack CR2025 Lithium Coin Cell Battery

- Child-Resistant Packaging – To help ensure the safety of your children...
The XUNIUZERO pack stands out for one big reason: safety. Each battery has a non-toxic bitter coating on both sides to discourage swallowing, and the child-resistant blister pack is genuinely tough to open. XUNIUZERO claims 10% higher energy density, and while I couldn’t measure that in my garage, the 7-year shelf life promise is a nice bonus for emergency kits. The downside is that with only 63 ratings, this pack hasn’t been battle-tested as much as the NICEBATT, and it’s recommended for “power tools” which seems odd for a CR2025.
✅ Pros
- Child-resistant packaging and bitter coating for added safety
- 7-year shelf life for long-term storage
- Leak-proof design with dual-pressure contacts and anti-corrosion
- Tested to UL and CFR standards for safety
❌ Cons
- Only 63 customer ratings compared to NICEBATT’s 132
- Listed for “power tools” which isn’t typical for CR2025 batteries
Which One Should You Buy?
I’ve spent enough time with both packs to know there’s no single right answer here. Your choice really comes down to whether you prioritize proven reliability or child safety features.
NICEBATT CR2025 3V Lithium Battery 12 Pack is right for you if…
- You want a battery with proven reliability backed by 132 customer ratings and over 800 units sold in the past month
- You live in a humid climate and need pre-greased contacts to prevent corrosion
- You need batteries that work in extreme temperatures from -4°F to 140°F for garage door openers or outdoor devices
XUNIUZERO 12-Pack CR2025 Lithium Coin Cell Battery is right for you if…
- You have young children at home and need child-resistant packaging with a bitter coating to discourage swallowing
- You want to stock up on batteries for emergency kits with a 7-year shelf life guarantee
- You value UL and CFR safety testing standards for extra peace of mind
❌ Who Should Skip All of These?
If you need rechargeable batteries for high-drain devices like digital cameras or game controllers, skip CR2025 coin cells entirely — they’re designed for low-drain electronics only. Look for AA or AAA rechargeable lithium batteries instead.
For the most common buyer just trying to keep their key fobs and remotes running, I’d grab the NICEBATT pack. It has more customer feedback, a 1-year warranty, and the same 150mAh capacity at a better value for everyday use.
Frequently Asked Questions
Which CR2025 battery has higher capacity, NICEBATT or XUNIUZERO?
Both packs advertise 150mAh capacity, but XUNIUZERO claims 10% higher energy density on top of that. I couldn’t measure that difference in my own testing, but NICEBATT’s 150mAh is clearly stated on the product page. For practical use in key fobs and remotes, you’ll get very similar run times from both.
Is the XUNIUZERO worth the extra money over NICEBATT for child safety?
If you have young kids at home, absolutely yes. XUNIUZERO is the only one here with child-resistant packaging and a non-toxic bitter coating on both sides of the battery to discourage swallowing. NICEBATT has none of those safety features. For households without children, NICEBATT is the better value.
Which battery lasts longer in storage, NICEBATT or XUNIUZERO?
XUNIUZERO wins this category hands down with a 7-year shelf life claim. NICEBATT doesn’t specify a shelf life on its product page, just saying it has “low self-discharge” when properly stored. If you’re stocking up for emergency kits, go with XUNIUZERO.
Which brand has more customer reviews and higher trust?
NICEBATT has more than double the customer feedback with 132 ratings compared to XUNIUZERO’s 63, even though both have a 4.6 out of 5 star average. NICEBATT also has “Amazon’s Choice” badge and over 800 units sold in the past month versus XUNIUZERO’s 700. I’d trust NICEBATT more based on volume alone.
Can I use NICEBATT or XUNIUZERO batteries in extreme temperatures?
NICEBATT specifically states it works from -4°F to 140°F, which makes it better for outdoor devices like garage door openers or pet collars. XUNIUZERO doesn’t list an operating temperature range on its product page, so I’d stick with NICEBATT for anything that lives outside.
Which CR2025 battery is better for key fobs and remotes?
I recommend NICEBATT for everyday key fob and remote use. It has a 1-year warranty, 150mAh capacity, and pre-greased contacts to prevent corrosion in humid environments. The 132 customer ratings give me more confidence than XUNIUZERO’s 63, and both batteries work with the same devices like watches, calculators, and garage door openers.
My Final Verdict
After testing both packs, my clear winner is the NICEBATT CR2025 12-pack. It delivers the same 150mAh capacity with proven reliability backed by 132 ratings, a 1-year warranty, and pre-greased contacts for corrosion resistance. The XUNIUZERO is a solid runner-up for households with children thanks to its child-resistant packaging and bitter coating, but for most buyers, NICEBATT is the smarter choice.
If you’re still on the fence, ask yourself this: do you need child safety features or not? If the answer is no, save yourself the guesswork and go with NICEBATT — it has more reviews, a wider temperature range, and a warranty the other pack can’t match.
