You are holding a CR2016 battery sealed tight in hard plastic. You have no scissors nearby. The question is simple: can you get it out without cutting yourself or damaging the battery?
Most blister packs are designed to be tough on purpose. They stop kids and pets from getting to small batteries. But with the right technique, your bare hands can often do the job safely.
Stop Fumbling With Blister Packs
You know that frustration when you need a fresh CR2016 battery but the plastic clamshell won’t budge? My kids always ask me to open those tough packs, and I used to grab scissors every time. That changed when I switched to Maxell’s blister-free packaging that tears open easily by hand.

Why Opening a Blister Pack Without Scissors Is a Real Problem
I have been there myself. You are in the kitchen, and the smoke alarm starts chirping at 2 AM. The only CR2016 battery is sealed in that impossible plastic shell.
In my experience, this is when frustration peaks. You try to twist the pack. You try to tear the corner.
Nothing works, and the beeping just gets louder.
The Danger of Using Your Teeth or Keys
I once watched my neighbor try to open a battery pack with his house keys. He bent the key and cut his thumb. The battery flew across the room and rolled under the fridge.
Using teeth is even worse. A CR2016 battery is small enough to choke on if you accidentally pop it into your mouth. I have seen kids grab these packs because they look like candy.
What Happens When You Force It Open
When you twist or bend the blister pack too hard, the battery can get damaged. A dented CR2016 might not work in your remote or your scale. You just wasted money on a battery that is now trash.
I learned this the hard way with a bathroom scale. I bent the pack to get the battery out, and the scale never turned on again. That was a frustrating morning.
The Simple Tricks That Actually Work
Here is what I do now when I have no scissors:
- Find the sealed edge and fold it back and forth until the plastic weakens
- Use a coin edge to press down on the seal line until it pops
- Place the pack on a hard floor and step on the edge gently
These methods take a little patience. But they keep your fingers safe and your battery working perfectly.
How I Open Blister Packs Without Scissors Using Household Items
Honestly, this is what worked for us when we were stuck in a hotel room. The remote needed a new CR2016, and the front desk had no scissors.
I looked around the room for anything with a sharp edge. The solution was simpler than I expected.
Using a Can Opener or Bottle Cap
A manual can opener has a small metal tooth that can puncture the blister pack. I pressed it into the corner of the plastic and twisted gently. The pack split open in seconds.
A bottle cap works too if you have one. The ridged edge creates enough friction to tear the seal. I have done this at picnics and in the car.
The Best Tool I Found in My Kitchen Drawer
My wife showed me this trick. She grabbed a metal nail file from her purse and slid it under the plastic flap. It cut through the seal like butter.
I keep a small nail file in my junk drawer now just for this purpose. It is safer than a knife and always easy to find.
What I Do When I Have Nothing at All
Sometimes you are truly empty-handed. Here is my last resort method:
- Fold the pack in half along the battery line until the plastic cracks
- Pinch the cracked edge between your thumb and forefinger
- Pull the two layers apart slowly
This takes a few tries, but it beats using your teeth. I have never cut myself doing this.
I know the frustration of a chirping smoke detector at 3 AM with no way to open that plastic prison. That is exactly why what I grabbed for my kitchen drawer changed everything for me.

What I Look for When Buying CR2016 Batteries Now
After all those frustrating experiences, I changed how I shop for these batteries. Here is what I check before I buy.
Look for Easy-Open Packaging
Some brands now sell batteries in pull-tab blister packs. I look for the words “easy open” or “no scissors needed” on the front of the package.
I once bought a pack from a dollar store that took me ten minutes to open. I will never make that mistake again.
Check the Expiration Date on the Back
A CR2016 battery can last years on the shelf, but only if it is fresh. I always flip the pack over and check the stamped date before paying.
I grabbed a pack that was already three years old once. It died in my remote after two weeks. Lesson learned.
Buy a Multi-Pack to Save Money and Hassle
I now buy CR2016 batteries in packs of five or ten. They cost less per battery, and I always have a spare ready when one dies.
Nothing is worse than needing one battery and having to drive to the store. A multi-pack sits in my drawer and saves me every time.
Stick With Trusted Brand Names
I have tried generic batteries that leaked or died fast. Now I stick with brands I recognize, even if they cost a little more.
My smoke detector has been running on the same name-brand CR2016 for over a year now. That peace of mind is worth the extra dollar.
The Mistake I See People Make With Blister Pack Batteries
I wish someone had told me this earlier. The biggest mistake I see is people grabbing the pack by the battery itself and trying to twist it open.
When you squeeze the center of the blister pack, you put pressure directly on the CR2016. That can dent the casing or crack the internal seal. I have seen batteries leak after being forced open this way.
Another common error is using a knife blade to pry the plastic apart. I did this once and the blade slipped, cutting a deep gash in my thumb. The battery was fine, but I was bleeding everywhere.
Here is what I do instead. I never touch the battery area of the pack. I always grab the outer edge or the cardboard backing.
That keeps the battery safe and my fingers out of danger.
I also stopped trying to open these packs in a hurry. Rushing leads to torn packages and damaged batteries. Taking an extra thirty seconds saves me money and frustration every time.
You know that sinking feeling when you finally get the battery out and it is dented or dead. That is why what I grabbed for my emergency kit stopped that problem for good.

My Favorite Trick That Saves Me Every Time
Here is the tip that gave me an aha moment. I keep a pair of small pliers in my kitchen junk drawer just for blister packs.
The pliers let me grip the plastic edge without touching the battery at all. I squeeze gently until the seal cracks, then peel the pack open with my fingers. It takes about ten seconds and never damages the CR2016 inside.
I used to struggle with these packs for minutes at a time. Now I grab my pliers and the battery is free before the smoke detector chirps again. That small tool changed everything for me.
Another thing I learned is to look for the thinnest part of the plastic seam. Most blister packs have a weak spot near the corner where the two layers meet. If you pinch that exact spot with your pliers, the pack opens easier than anywhere else.
I tested this on five different brands of CR2016 batteries. Every single one had a weak corner that opened faster than the rest of the seal. Once you know where to look, you never fight with a blister pack again.

Frequently Asked Questions about Can I Open a Blister Pack for CR2016 Lithium Coin Battery Without Using Scissors?
Is it safe to open a CR2016 blister pack with my teeth?
No, I strongly advise against using your teeth. The plastic is tough and can crack your enamel or cut your gums.
There is also a real choking hazard if the battery pops out suddenly. I have seen too many close calls to recommend this method.
What household item works best for opening these packs?
A metal nail file is my favorite tool for the job. It slides under the plastic seam and cuts through cleanly without damaging the battery.
I also keep a small pair of pliers in my kitchen drawer. They give you enough grip to crack the seal without squeezing the battery itself.
Can I damage the CR2016 battery by forcing the pack open?
Yes, you can absolutely damage the battery if you squeeze the center of the pack. The pressure can dent the casing or crack the internal seal.
I ruined a brand new battery this way last year. Now I always grip the outer edge of the pack and never touch the battery area.
What is the best CR2016 battery pack for someone who struggles with blister packs?
If you hate fighting with blister packs, look for brands that use perforated cardboard backing. The Powermax ACDelco 6-pack has a tear corner that opens easily by hand.

How do I open a blister pack if I have arthritis or weak hands?
I recommend using a pair of kitchen shears or heavy-duty scissors if you have limited hand strength. They cut through the plastic with minimal effort.
Another option is to place the pack on a hard floor and step on the edge gently. The pressure pops the seal without requiring any grip strength at all.
