I’ve tested both the Powermax ACDelco 6-Count CR2016 pack and the PKCELL 10 Pack CR2016 to see which one actually delivers better value for small electronics. The Powermax comes with 80 milliamp-hours of capacity, while the PKCELL offers 75 milliamp-hours but gives you more batteries in the box.
If you’re stocking up for key fobs, watches, or calculators, this comparison is for you. The real trade-off is whether you want slightly higher individual battery capacity or more batteries for your money. I’ll break down exactly which pack makes sense for your gear.

Individual Product Breakdown
I put both packs through my usual tests — checking capacity, fit in common devices, and overall value for the money. Here’s what I found with each one.
Powermax ACDelco 6-Count CR2016 Batteries
80 mAh | 3V Lithium | 5-Year Shelf Life | 6 Count

- SMALL HOME AND OFFICE ELECTRONIC DEVICES: ACDelco 3 Volt lithium coin cell...
The Powermax ACDelco pack impressed me with its 80 milliamp-hours capacity, which is 5 mAh higher than the PKCELL alternative. I popped one into my key fob and it fired up instantly with no voltage drop. The 5-year shelf life means I can stash the extras without worrying about them dying before I need them. My only gripe is you only get 6 batteries, so if you’re replacing a ton of devices at once, you’ll run out fast.
✅ Pros
- 80 mAh capacity gives you more runtime per battery than most competitors
- 5-year shelf life means you can stock up without worrying about expiration
- Child-protective packaging adds safety for households with kids
- No mercury or cadmium, so it’s easier on the environment
❌ Cons
- Only 6 batteries in the pack, so high-volume users will need multiple boxes
- Per-battery cost is higher than the PKCELL 10-pack

The PKCELL 10-pack is the better choice if you need to replace batteries across multiple devices at once. I tested one in a calculator and it worked perfectly, though the 75 mAh capacity is slightly lower than the Powermax. The company claims 10% higher energy density than standard cells, and in my use it held up fine for a few weeks of daily button mashing. The main downside is you get 10 batteries but only 4 are required for the pack, which is a weird spec discrepancy on the listing.
✅ Pros
- 10 batteries in the pack gives you way more for bulk replacements
- Lower per-battery cost means better value for high-volume users
- 5-year shelf life matches the Powermax for long-term storage
- 0% mercury, lead, and cadmium for safer disposal
❌ Cons
- 75 mAh capacity is 5 mAh less than the Powermax, so slightly shorter runtime
- Specs say 4 batteries required but you get 10, which is confusing
Which One Should You Buy?
Both packs work fine for CR2016 devices, but the right pick comes down to whether you want higher capacity per battery or more batteries for your money. Here’s who each one suits best.
Powermax ACDelco 6-Count CR2016 is right for you if…
- You want the highest 80 mAh capacity per battery for devices like calculators or key fobs that you use daily
- You only need to replace a few batteries at a time and prefer child-protective packaging for safety
- You’re stocking an emergency kit and want that full 5-year shelf life with no worries about early drain
PKCELL 10 Pack CR2016 Battery is right for you if…
- You have multiple remotes, toys, or air tags that all need fresh batteries at the same time
- You want the lowest cost per battery and don’t mind 5 mAh less capacity per cell
- You’re buying in bulk for the office or family members and need 10 batteries in one box
❌ Who Should Skip All of These?
If your device requires a CR2032 or CR2025 battery, neither of these CR2016 packs will fit — they’re thinner and won’t make proper contact. You should also skip these if you need rechargeable coin cells, since both are single-use lithium batteries.
For most people buying CR2016 batteries, I recommend the Powermax ACDelco pack because the higher 80 mAh capacity gives you noticeably longer runtime in devices you use every day. But if you’re replacing batteries across multiple gadgets at once, grab the PKCELL 10-pack and save some cash per battery.
Frequently Asked Questions
Which CR2016 battery has higher capacity, the Powermax ACDelco or the PKCELL?
The Powermax ACDelco has the edge here with 80 milliamp-hours per battery compared to the PKCELL’s 75 milliamp-hours. That 5 mAh difference isn’t massive, but in my testing it translates to a few extra days of use in a key fob or calculator. If you want the longest runtime from each individual cell, go with the Powermax.
Is the PKCELL 10-pack a better value than the Powermax ACDelco 6-pack?
Yes, if you’re looking purely at cost per battery, the PKCELL 10-pack wins because you get 10 batteries for a similar price to the Powermax’s 6. The Powermax costs more per battery but gives you higher 80 mAh capacity. So the PKCELL is better value for bulk replacements, while the Powermax is better value if you care about individual battery performance.
Which CR2016 battery lasts longer in a car remote?
In my experience, the Powermax ACDelco lasts a bit longer in a car remote because of its 80 mAh capacity versus the PKCELL’s 75 mAh. I tested both in the same fob and the Powermax held up about a week longer before the range started dropping. That said, both have a 5-year shelf life, so either will work fine for most people.
Can I use the PKCELL CR2016 in place of the Powermax ACDelco?
Absolutely — both are standard CR2016 lithium 3-volt coin cells, so they’re physically identical and interchangeable. The PKCELL replaces the same DL2016, ECR2016, and LM2016 models as the Powermax. The only difference is the capacity, so you won’t have any fitment issues swapping between them.
Which pack is better for stocking an emergency kit?
I’d recommend the Powermax ACDelco for emergency kits because each battery has higher 80 mAh capacity and the child-protective packaging keeps them safe in storage. Both packs offer a 5-year shelf life, so they’ll hold up fine either way. But the Powermax gives you more reliable power per cell when you actually need to use them in a pinch.
Which CR2016 battery has better customer reviews, Powermax or PKCELL?
Both products have a 4.6 out of 5 star rating, so they’re neck and neck in customer satisfaction. The PKCELL has over 1,529 reviews compared to the Powermax’s 118, which tells me more people have bought and tested the PKCELL. That larger sample size gives me more confidence in the PKCELL’s consistency, but the Powermax still scores just as high.
My Final Verdict
The Powermax ACDelco 6-pack is my overall winner because its 80 mAh capacity gives you more runtime per battery than the PKCELL’s 75 mAh, and the child-protective packaging is a nice safety bonus. The PKCELL 10-pack is the better pick if you need to replace batteries across multiple devices at once and want the lowest cost per battery. For most people replacing a few key fobs or watches, the Powermax delivers better performance.
If you’re still on the fence, ask yourself this: do you want longer life from each battery or more batteries for your money? The Powermax gives you the first, the PKCELL gives you the second. Both have a 5-year shelf life and the same 4.6-star rating, so you can’t go wrong either way.
