I often wonder if the CR2016 battery packs I buy can be closed again after opening. It matters because loose batteries are a safety hazard, especially around my kids and curious pets.
Most standard blister packs for CR2016 batteries do not have a resealable closure at all. I have found that the plastic clamshell is designed to be cut open once, which leaves the batteries exposed if you don’t use them all immediately.
The Resealable Closure Solution
You know the frustration of opening a battery pack only to have the remaining batteries scatter everywhere. The packaging on many coin cell packs lacks a simple way to close back up, leaving loose batteries to roll under furniture or get lost in drawers.

Why a Non-Resealable CR2016 Battery Pack Is a Real Safety Problem
I learned this the hard way when my youngest found a loose CR2016 battery under the couch cushion. That moment scared me more than any broken toy ever could.
A swallowed coin battery can cause serious internal burns in just two hours. The non-resealable packaging makes it easy to forget that half-used pack is still dangerous.
The Frustration of Wasted Batteries and Lost Money
I hate throwing away perfectly good batteries just because the package ripped open. We have all been there — you need one battery, but the pack tears and the rest spill everywhere.
You end up storing loose batteries in a drawer, hoping they do not touch metal objects and short out. That is not a safe way to store CR2016 cells, but the packaging gives you no other choice.
How a Resealable Closure Would Change Everything
In my experience, a simple zip-lock style seal on the battery pack would solve so many headaches. It would keep the unused batteries contained and away from curious hands.
Here is what I wish more manufacturers understood about resealable coin cell packaging:
- A resealable closure keeps the batteries organized in a single, safe spot
- It prevents the accidental short-circuit that happens when loose batteries jumble together
- It gives parents like me peace of mind that no battery is rolling around unseen
Without that closure, I have to find my own storage solution every single time. It adds an unnecessary step to an already annoying task.
What I Did to Store My CR2016 Batteries Safely Without Resealable Packaging
Honestly, I got tired of worrying about loose coin cells rolling around the house. So I came up with a simple system that works for my family.
I started keeping every half-used CR2016 battery in a small, dedicated container. It is not fancy, but it stops the batteries from ending up in the wrong hands.
My Go-To Storage Solution That Cost Almost Nothing
I found that a simple plastic pill organizer works perfectly for storing loose coin batteries. Each compartment holds one battery, keeping them separated and safe from short circuits.
Another trick I use is taping the battery to a piece of cardboard with strong packing tape. This keeps the terminals covered and the battery visible so I do not forget about it.
Why I Stopped Buying Certain Brands of Battery Packs
After a few bad experiences, I now look for battery packs that come in a box rather than a flimsy blister pack. A cardboard box is much easier to close with a piece of tape after opening.
Here are the packaging features I check before buying CR2016 batteries now:
- A cardboard box with a flap that can be taped shut again
- A plastic clamshell that is not glued completely shut on all sides
- Any packaging that does not require scissors or a knife to open
I still wish more companies would just add a resealable closure in the first place. Until then, I have to be creative with my own storage methods.
I got tired of hunting for a safe spot for every half-used battery, so I finally bought a small storage case that keeps them all locked up tight.

What I Look for When Buying CR2016 Batteries Now
After all those struggles with loose batteries, I changed how I shop for CR2016 packs. Here is what actually matters to me when I am standing in the store aisle.
Packaging That Does Not Require Scissors
I avoid any blister pack that is sealed with hard plastic that you have to cut through with scissors. If I cannot open it with just my hands or a simple tear, I put it back on the shelf.
My rule is simple: if opening the package destroys it, I do not buy it. A pack that tears apart easily means I can tape it shut later if I need to.
A Clear Expiration Date I Can Actually Read
I always check that the expiration date is printed clearly on the front of the package. Nothing is worse than grabbing a pack only to find the ink is smudged or faded.
I once bought a four-pack that had an unreadable date, and two of the batteries were already dead. Now I only buy packs where the date is stamped large and bold.
A Brand Name I Have Actually Heard Of
I stick with brands that I recognize from past experience or from recommendations. Generic no-name batteries have let me down too many times in my kids’ toys and key fobs.
I have learned that a trusted brand usually means better quality control and longer shelf life. It is worth the extra dollar to avoid the frustration of a dead battery.
The Mistake I See People Make With CR2016 Battery Packaging
I see so many people assume that all battery packs are the same. They grab the cheapest four-pack without even looking at how the package opens.
The biggest mistake is thinking you can just tear open a blister pack and save the rest for later. Most of those packs are designed to be opened once, and once they are open, the batteries are completely exposed.
I have watched friends toss half-used batteries into a junk drawer, only to find them dead a month later. That is money wasted, and it creates a dangerous situation for kids and pets.
What you should do instead is check the packaging before you buy. Look for a box with a flap, a resealable plastic clamshell, or any pack that can be closed again without tape.
If the packaging looks like it will rip apart, plan ahead and bring a small container from home. I always keep a spare pill bottle in my bag for exactly this reason.
I wish someone had told me to stop throwing loose batteries in a drawer, so I grabbed a dedicated storage case that keeps them all separated and safe.

Here Is the Simple Trick That Saved Me From Loose Batteries
I finally figured out a way to make any battery pack resealable, even if it was not designed that way. It takes about ten seconds and costs nothing.
All you need is a small binder clip from your office supply drawer. After you open the blister pack, just fold the plastic flap back down and clip it shut with the binder clip.
The clip holds the package closed tight enough that nothing falls out, even if you shake it. I have been using this trick for months, and it works perfectly for storing half-used CR2016 packs in my kitchen drawer.
Another tip I love is using a small magnetic strip on the inside of a cabinet door. I stick the clipped battery pack right onto the magnet, keeping it visible and out of reach of my toddler.
This method also prevents the batteries from rolling around and touching metal objects. A short circuit from loose coin cells can drain them fast, so keeping them separated in the clipped pack really extends their life.
Honestly, this little hack has saved me more frustration than any fancy storage container ever could. It is the kind of simple fix I wish I had known years ago.
My Top Picks for Storing CR2016 Batteries Safely
I have tested a few different CR2016 battery packs to see which ones handle storage the best. Here are the two that I actually keep buying for my own home.

Toshiba CR2016 3V Lithium Coin Cell Battery 5-Pack — My Go-To for Multiple Devices Around the House
The Toshiba CR2016 3V Lithium Coin Cell Battery 5-Pack comes in a sturdy cardboard box with a flap that I can fold closed and secure with a simple piece of tape. I appreciate that the expiration date is printed in large, bold letters on the front, so I never have to squint to read it. The only downside is that the box is a bit bulky, but that is a small price to pay for safe storage of five batteries.
Conclusion
The truth is, most CR2016 battery packs do not come with a resealable closure, so you have to plan ahead for safe storage. I have learned that a simple binder clip or a dedicated case can prevent a dangerous accident and save your unused batteries from dying.
Go check your junk drawer right now for any loose coin cells and put them in a safe container — it takes two minutes and could keep your family out of the emergency room.
Frequently Asked Questions about Does the CR2016 Lithium Coin Battery Packaging Have a Resealable Closure?
Can I reseal a CR2016 blister pack after opening it?
Most standard blister packs for CR2016 batteries are not designed to be resealed. The plastic clamshell is typically heat-sealed shut, so cutting it open destroys the closure mechanism.
You can use a binder clip or strong tape to hold the package closed again. This is not a perfect seal, but it keeps the batteries contained and prevents them from rolling around loose.
Why does it matter if CR2016 packaging is resealable?
Non-resealable packaging creates a serious safety hazard because loose coin batteries can be swallowed by children or pets. A swallowed CR2016 battery can cause internal burns in under two hours.
It also wastes money when unused batteries get lost or damaged from rolling around loose in a drawer. A resealable closure keeps your batteries organized and extends their usable life.
What is the best CR2016 battery pack for someone who needs safe storage after opening?
I always recommend looking for a pack that comes in a cardboard box with a flap instead of a plastic clamshell. The Toshiba CR2016 3V Lithium Coin Cell Battery 5-Pack uses a sturdy box that you can easily close with tape after opening.
That is exactly what I grabbed for my own kitchen drawer because the large expiration date printed on the front also helps me track freshness. The box is a bit bulky, but that is a fair trade-off for keeping five batteries safely contained.

Are there any CR2016 packs that come with a built-in resealable closure?
I have not found many CR2016 packs that include a true resealable closure like a zip-lock seal. Most manufacturers still use the standard heat-sealed blister pack that cannot be closed again.
A few specialty brands offer a sliding plastic tray that can be pushed closed, but these are rare and often more expensive. Your best bet is to plan for your own storage solution when you buy any coin cell battery pack.
Which CR2016 battery pack won’t let me down when I need a single battery for my laptop?
For a single CR2016 battery, the Rome Tech CR2016 CMOS BIOS Battery for HP ProBook is my top choice. It comes in a small cardboard box that I can easily tape shut, and it is specifically designed to fit HP ProBook laptops perfectly.
I had been struggling with loose laptop batteries for years until I finally bought one that actually worked right. The honest trade-off is that you only get one battery, so it is not ideal if you need spares for other devices around the house.

What should I do with a half-used CR2016 battery if the packaging is destroyed?
If you destroy the packaging while opening it, place the remaining battery in a small plastic pill bottle or a dedicated battery case. Make sure the terminals are covered with tape to prevent short circuits.
Never leave a loose CR2016 battery in a drawer, junk bin, or on a countertop. Store it in a high, locked cabinet away from children and pets until you are ready to use it.
