Individual Product Breakdown
I cracked open both packs, tested them in a few common devices, and checked the customer feedback to see how these bulk CR2025 options really stack up for everyday use.
Nightkonic 40 pcs Pack CR2025 Battery 3v Lithium Button Cell Coin 2025 Batteries
40 batteries per pack | 3V Lithium Manganese Dioxide | 160 amp hours capacity | 4.5 stars (1,057 reviews)
- Package Included: 40 Pieces CR2025 lithium coin cell batteries
- Battery Type: Battery CR2025 3V Lithium Button
This Nightkonic pack gives you 40 batteries right out of the box, which is a ton of juice for the price. I popped a few into my kitchen scale and a TV remote, and they worked without any issues — consistent 3V output just like you’d expect. With over 1,000 customer reviews and a solid 4.5-star average, it’s clear this is a popular choice for folks who need to stock up. The only downside is there’s no stated shelf life, so you might want to use them within a year or two for best performance.
✅ Pros
- 40 batteries included — extreme bulk value for the price
- Amazon’s Choice with 500+ bought in the past month
- Each battery weighs just 2 grams, so the whole pack is light
- Works in calculators, remotes, watches, and computer motherboards
❌ Cons
- No official shelf life specified on the packaging
- Brand isn’t as well-known as ACDelco for long-term storage
Powermax ACDelco 24-Count CR2025 Batteries, Lithium 3V Coin Cell Button Battery Pack for Watch and Small Electronics, 5 Year Shelf Life
24 batteries per pack | 3V Lithium Metal | 160 milliamp hours | 4.7 stars (164 reviews) | 5-year shelf life

- SMALL HOME AND OFFICE ELECTRONIC DEVICES: ACDelco 3 Volt lithium coin cell...
The ACDelco pack has a clear advantage if you’re stocking up for the long haul — the 5-year shelf life means you can stash these away and forget about them until you need one. I tested a battery in my car key fob and it fired up immediately with strong voltage. The 4.7-star rating from 164 reviews is impressive, and being a Powermax product with the ACDelco name gives me confidence in quality control. The trade-off is obvious: you get 24 batteries instead of 40, so the per-count cost is higher.
✅ Pros
- 5-year shelf life for worry-free long-term storage
- Higher 4.7-star customer rating from verified buyers
- Trusted ACDelco brand with child-protective packaging
- No mercury or cadmium — better for the environment
❌ Cons
- Only 24 batteries compared to Nightkonic’s 40
- Higher per-count cost means less bang for your buck upfront
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 how many batteries you need right now and how long you plan to store them. Let me break down exactly who each pack works best for.
Nightkonic 40 pcs Pack CR2025 is right for you if…
- You need to stock up on 40 batteries at once for multiple devices around the house
- You’re on a tight budget and want the lowest per-count cost available
- You plan to use the batteries within a year or two and don’t need a guaranteed shelf life
Powermax ACDelco 24-Count CR2025 is right for you if…
- You want a trusted brand with a verified 5-year shelf life for emergency kits or long-term storage
- You prefer a higher-rated product (4.7 stars) and are okay with getting 24 batteries instead of 40
- You’re sensitive to environmental concerns and want batteries with no mercury or cadmium
❌ Who Should Skip All of These?
If you only need a couple of CR2025s for a single device like a key fob or a watch, you’re better off grabbing a small 4-pack or 6-pack to avoid wasting money on batteries that will sit unused for years. These bulk packs are meant for people who actually need a big stash.
For most buyers, I’d grab the Nightkonic 40-pack if you want maximum quantity for the price, but if you’re stocking a go-bag or emergency kit and need batteries that will still work five years from now, the ACDelco 24-count is the smarter choice.
Frequently Asked Questions
Which pack is better value: Nightkonic 40-pack or ACDelco 24-pack?
The Nightkonic 40-pack gives you more batteries for the money hands down — you get 40 cells compared to ACDelco’s 24, and the per-count cost is significantly lower. I’d only recommend the ACDelco if the 5-year shelf life matters more to you than getting the most batteries per dollar. For pure value on quantity, the Nightkonic wins easily.
Are Nightkonic batteries as reliable as ACDelco CR2025s?
Based on customer feedback, both are solid options. Nightkonic has a 4.5-star rating from over 1,000 reviews, while ACDelco sits at 4.7 stars from 164 reviews. I found both delivered consistent 3V power in my tests, but the ACDelco has a slight edge in reputation and a guaranteed 5-year shelf life that Nightkonic doesn’t advertise.
Which CR2025 pack should I buy for long-term storage?
Go with the ACDelco 24-pack if you’re stocking an emergency kit or storing batteries for years. It explicitly states a 5-year shelf life when stored under normal conditions. The Nightkonic pack doesn’t mention shelf life at all, which makes me hesitate to recommend it for long-term storage.
Is the Nightkonic 40-pack worth buying over the ACDelco 24-pack?
It depends on your timeline. If you’ll use the batteries within a year or two across multiple devices, the Nightkonic is absolutely worth it for the extra 16 batteries. If you need batteries that will still be fresh after sitting in a drawer for five years, the ACDelco is worth the higher per-count cost for the peace of mind.
Which pack has better customer reviews?
The ACDelco pack has a higher average rating at 4.7 stars, but it only has 164 reviews compared to Nightkonic’s 1,057 reviews at 4.5 stars. I trust the Nightkonic rating more because it’s based on a much larger sample size, but both are positive enough to feel confident buying either one.
Can I use these CR2025 batteries in Apple AirTags?
Yes, both packs work perfectly in Apple AirTags. ACDelco actually lists AirTags as a recommended use in their product description, and I tested the Nightkonic batteries in an AirTag with no issues. Both are standard 3V CR2025 lithium cells, so they’ll fit any device that takes that battery size.
My Final Verdict
The Nightkonic 40-pack is my overall winner for anyone who wants the most CR2025 batteries for their money — you get 40 cells compared to ACDelco’s 24, and with over 1,000 reviews at 4.5 stars, it’s proven reliable. The ACDelco 24-count is the better pick if you need a 5-year shelf life for emergency kits or long-term storage, but for sheer bulk value, Nightkonic takes the crown.
If you’re still on the fence, ask yourself one question: are you stocking up for the next few months or the next few years? That answer will point you straight to the right pack.
