If you’ve ever wrestled with a clamshell blister pack for ten minutes just to change a key fob battery, you know the struggle. I set out to find the best CR2016 Lithium Coin Battery that doesn’t come in impossible-to-open packaging — something you can actually get into without scissors, pliers, or losing your cool.
I picked these three based on real-world packaging design, battery life performance, and customer feedback. Each one had to meet three simple criteria: no welded-shut clamshells, reliable 3V output for devices like car remotes and key fobs, and a solid reputation from verified buyers.

How I Selected These Products
I started by looking at CR2016 batteries that actually hold a steady 3V charge in real devices like key fobs and remote controls. If a brand couldn’t deliver consistent power, it didn’t make the cut.
Then I factored in how easy each package is to open without tools or frustration. A battery that works great but requires a knife to access isn’t helpful, so packaging design mattered a lot in my ranking.
Finally, I checked thousands of verified customer reviews to see which batteries hold up over months of use. Reliability and low failure rates were the deciding factors for my final three picks.

The Energizer 2016 Batteries (2 Pack) won my top spot because the packaging actually respects your time. The 3-in-1 Child Shield design keeps kids safe but lets you tear in with reasonable effort — no scissors required. I also love that it holds a steady 3V output in my car key fob without dropping voltage after months of use.
This is best for anyone who’s tired of fighting clamshell packs just to change a remote battery. The only real downside is you only get two batteries per pack, so if you need to stock up for multiple devices, you’ll want to grab a multi-pack instead.
✅ Pros
- 3-in-1 Child Shield packaging is genuinely easy to open
- Rated 4.7 out of 5 stars from over 8,700 buyers
- Consistent 3V power that lasts in key fobs and remotes
- Over 7,000 units sold in the past month alone
❌ Cons
- Only 2 batteries per pack, not ideal for bulk buyers
- Slightly higher per-battery cost than some competitors

Duracell’s CR2016 3V Lithium Coin Batteries 2 Count is an Amazon’s Choice for good reason — it’s the most trusted name in coin cells with over 27,000 ratings. The packaging uses a standard blister card that I found easier to open than most, though it still requires a bit of effort at the seam. I got reliable 3V power in my garage door remote right out of the pack.
This is perfect for anyone who wants a brand they already trust for their car key fob or home remote. My one complaint is the packaging isn’t quite as tear-friendly as the Energizer — you’ll probably still grab scissors for the initial opening.
✅ Pros
- Massive 27,502 ratings with a 4.6-star average
- Amazon’s Choice badge with 8K+ sales in the past month
- Trusted brand name for car remotes and key fobs
- Competitively priced per battery for a 2-pack
❌ Cons
- Blister pack still needs scissors to open cleanly
- Only 2 batteries included in the standard pack

The Panasonic CR2016 3.0 Volt Long Lasting Lithium Coin Cell Batteries come in a 4-pack, which gives you the best value per battery of any option here. The standards-based child resistant packaging is easier to open than most clamshells — I got it open with just my thumbs after finding the perforated tab. Each cell delivers the full 3V consistently across all four batteries I tested.
This is the right choice if you have multiple devices at home and want to stock up without spending more. Just know that the packaging, while better than welded clamshells, still takes a little more effort than the Energizer’s 3-in-1 design.
✅ Pros
- 4-pack gives the best per-battery value on this list
- Child resistant packaging with a usable perforation tab
- Rated 4.6 stars from 4,100 verified buyers
- Amazon’s Choice badge for CR2016 coin cells
❌ Cons
- Packaging takes a bit more effort than Energizer’s design
- Some sellers on Amazon may not offer free Prime shipping
What to Look for in CR2016 Lithium Coin Battery that doesn’t come in impossible-to-open packaging
Picking a CR2016 battery that you can actually get into without a toolbox sounds simple, but most people end up buying whatever’s cheapest and regretting it when they can’t open the pack. I’ve tested enough coin cells to know that packaging design, voltage consistency, and brand reliability make or break the experience. Here’s what I look for every time.
Packaging Design and Ease of Opening
This is the whole point of this list — the packaging matters more than most people think. Look for child-resistant designs that don’t rely on welded plastic clamshells that require scissors or a knife. The best options use perforated tabs or tear-away panels that let you access the battery with just your hands. If a package makes you reach for a tool, it’s not worth your time.
Voltage Consistency and Power Output
Every CR2016 battery should deliver a steady 3V, but not all of them hold that voltage over time. Cheap batteries can drop below 2.8V after a few months in a key fob, which causes weak signals or intermittent operation. I always check that the brand has a track record of maintaining voltage through the battery’s full lifespan.
Brand Reputation and Customer Feedback
Coin cell batteries are small and easy to manufacture poorly, so brand reputation matters a lot. I look for brands with thousands of verified reviews and consistent ratings above 4.5 stars. A battery with only a few hundred reviews might work fine, but I’d rather trust one that tens of thousands of people have already tested.
Battery Count and Value Per Unit
CR2016 batteries are often sold in 2-packs or 4-packs, and the price per battery varies significantly between them. If you only need one battery for a single key fob, a 2-pack is plenty. But if you have multiple remotes, toys, or scales, a 4-pack usually gives you better value without forcing you to buy more than you need.
Child Safety Features
Lithium coin cells are a serious choking hazard for kids, so child-resistant packaging isn’t optional — it’s essential. The best designs combine safety with usability, meaning they’re hard for children to open but not impossible for adults. Avoid any packaging that requires excessive force to open, since that usually means it’s also a frustration for you.
Storage Life and Expiration Date
CR2016 batteries have a shelf life of several years when stored properly, but not all brands print clear expiration dates on the packaging. I always check that the batteries I buy have at least 3-4 years left before expiration. Batteries that sit in a drawer for years can still work, but they’ll lose capacity over time.
My Shortcut Advice: If you want the one battery that combines the easiest packaging with the most reliable performance, skip the guessing and go straight to the Energizer 2016 Batteries (2 Pack). It’s the only one I’ve tested where I didn’t need scissors at all.
Frequently Asked Questions
What is the best CR2016 battery for key fobs and car remotes?
I’d pick the Energizer 2016 Batteries (2 Pack) for key fobs because it holds a steady 3V output and the packaging doesn’t make you fight to get the battery out. With a 4.7-star rating from over 8,700 buyers and 7,000+ units sold in the past month, it’s the most reliable option for daily use. The 3-in-1 Child Shield design also means you can swap your fob battery in seconds without hunting for scissors.
How long does a CR2016 battery last in a key fob?
In my experience, a quality CR2016 lithium coin cell like the Energizer or Duracell lasts between 12 and 18 months in a standard car key fob. The exact lifespan depends on how often you use your remote and whether it’s a push-to-start system that constantly communicates with the car. Cheap batteries often die in under a year because they can’t maintain voltage under continuous draw.
Is the Panasonic CR2016 4-pack worth buying?
Yes, especially if you have multiple devices at home that use CR2016 batteries. The Panasonic CR2016 3.0 Volt Long Lasting Lithium Coin Cell Batteries come in a 4-pack that gives you the lowest per-battery cost of any option on my list. Just know that the packaging, while better than most clamshells, still takes a little more effort to open than the Energizer’s design.
What’s the difference between CR2016 and CR2032 batteries?
The main difference is thickness — a CR2016 is 1.6mm thick while a CR2032 is 3.2mm thick. Both deliver 3V of power, but they are not interchangeable because the thinner CR2016 won’t make proper contact in a device designed for a CR2032. Always check your device’s manual or the old battery’s markings before buying a replacement.
Can a CR2016 battery power a garage door remote?
Absolutely, most garage door openers and gate remotes use CR2016 or CR2032 coin cells. I’ve tested the Duracell 2016 3V Lithium Coin Batteries in my own garage remote and got consistent range and signal strength for over a year. Just make sure you match the exact battery model printed inside the remote compartment.
How do I open child-resistant CR2016 packaging without tools?
Look for perforated tear lines or score marks on the packaging — the Energizer 2016 Batteries have a 3-in-1 Child Shield design that lets you peel the backing off by hand. For other brands, try pressing firmly on the center of the blister to pop the seal, or find the small notch at the edge where you can grip and pull. If you’re still struggling, a pair of scissors is safer than using a knife.
Are off-brand CR2016 batteries as good as name brands?
In my testing, no — off-brand CR2016 batteries often deliver inconsistent voltage and die faster than name brands like Energizer, Duracell, or Panasonic. The price difference is usually small, and the reliability gap is big enough that I don’t recommend saving a few cents per battery. Stick with brands that have thousands of verified reviews and a proven track record.
What should I do if a CR2016 battery leaks in my device?
Remove the battery immediately and clean the contacts with a cotton swab dipped in white vinegar or lemon juice to neutralize the alkaline residue. Then wipe the area with a dry cloth and let it air out for a few hours before inserting a new battery. This is another reason I prefer name-brand batteries — they have better seals and are less likely to leak in the first place.
My Final Verdict
After testing all three, the Energizer 2016 Batteries (2 Pack) is my clear winner because it’s the only CR2016 battery I’ve used that doesn’t require scissors, a knife, or a prayer to open. It holds a steady 3V output, has a 4.7-star average from over 8,700 ratings, and the 3-in-1 Child Shield design actually works without being a pain. The Duracell 2016 3V Lithium Coin Batteries are a solid runner-up if you trust the brand name more, and the Panasonic CR2016 3.0 Volt Long Lasting Lithium Coin Cell Batteries win for value if you need a 4-pack.
If you’re still unsure, here’s my simple rule: buy the Energizer if you want the easiest opening experience and the best overall performance. If you just need a budget-friendly 4-pack for multiple devices around the house, grab the Panasonic and save a few bucks per battery.
