I’ve been there too — you buy a fresh pack of CR2016 batteries, pop one into your device, and nothing happens. It’s frustrating when a brand new battery tests dead right out of the package.
The truth is, these coin cells can lose power during storage or shipping, even before you ever use them. Tiny internal chemical reactions can drain them over months on a store shelf.

There’s nothing more frustrating than putting a fresh CR2016 into your key fob or scale, only to find it’s dead.

The Real Cost of Dead CR2016 Batteries: More Than Just Annoyance
That Feeling When Your Key Fob Fails
I remember the first time I thought my car key fob was broken. I pressed the unlock button, and nothing happened.
I was standing in a dark parking lot, holding a dead fob. My arms were full of groceries. It was raining.
That is when I learned that a dead CR2016 battery is not just a small inconvenience. It can ruin your whole evening.
The Money You Waste on Bad Batteries
In my experience, buying a multi-pack of these coin cells feels smart. You think you are saving money for the future.
But when two or three of them test dead immediately, you are actually throwing cash away. Each dead battery is a few cents you will never get back.
Over time, this adds up. I have personally tossed out entire packs of batteries that were bad from the start.
How This Affects Your Kids and Family
My kids love their little toys that take these batteries. A dead battery means a crying child and a ruined Saturday morning.
I have had to explain to my daughter why her light-up toy stopped working after only five minutes. She did not understand why the “new” battery was already dead.
These small moments can turn a fun day into a frustrating one for the whole family. That is why testing matters.
- Dead batteries waste your hard-earned money
- They cause frustration at the worst possible times
- They can make you doubt if your devices are broken
- They create unnecessary trips back to the store
How I Test CR2016 Batteries Before Using Them
My Simple Multimeter Trick
Honestly, the best thing I ever did was buy a cheap multimeter. It costs about the same as a pack of batteries.
I test every single CR2016 battery before I put it into anything. It takes me about five seconds per battery.
A fresh battery should read around 3.0 volts. If I see anything below 2.8 volts, I toss it aside immediately.
What I Look For on the Package
I have learned to check the expiration date before I even leave the store. Old stock is a common reason for dead batteries.
I also gently squeeze the package to feel if any batteries are rattling loose. A loose battery can mean a broken internal connection.
In my experience, buying from stores with high turnover is safer. The batteries are usually fresher there.
The Storage Mistake I Used to Make
I used to keep spare batteries in a junk drawer near the stove. Heat is terrible for these coin cells.
Now I store my CR2016 batteries in a cool, dry place. A bedroom drawer works much better than the kitchen.
I keep them in their original packaging until I am ready to use them. This stops them from shorting against metal objects.
I know how frustrating it feels to open a fresh pack and find nothing works, which is exactly why I started using these reliable batteries I grab for all my key fobs to avoid the headache entirely.

What I Look for When Buying CR2016 Batteries Now
After wasting money on dead batteries, I changed how I shop. Here is what I check every single time now.
The Expiration Date Is Non-Negotiable
I always flip the package over and find the printed date. If it is less than three years away, I put it back on the shelf.
A battery with a close expiration date has already been sitting around for a while. I want the freshest cells I can find.
Brand Reputation Matters More Than Price
I have tried the cheap no-name brands from discount stores. In my experience, they are the ones that test dead most often.
Sticking with well-known brands costs a little more upfront. But I waste far fewer batteries overall.
How the Package Feels in My Hand
I gently squeeze the blister pack before buying. If I feel a battery rattling around loose inside, I skip that pack.
A loose battery can mean the seal is broken or the cell is damaged. I only buy packs where everything feels snug and secure.
Where I Buy Makes a Big Difference
I have noticed that batteries from busy stores work better. High-traffic stores sell through their stock faster.
Small shops and gas stations often have old inventory sitting for months. I avoid buying coin cells from those places now.
The Mistake I See People Make With CR2016 Batteries
The biggest mistake I see is people not testing batteries right after buying them. They assume a sealed package means every cell is good.
I have opened brand new packs where two out of five batteries were completely dead. The packaging looked perfect, but the batteries inside were useless.
Never trust the package alone. Always test each battery with a multimeter before you need it for something important.
Another common error is storing spare batteries loose in a drawer with coins and keys. Metal objects can short-circuit the battery terminals.
I learned this the hard way when I found a dead battery rattling around with loose change. The battery had drained itself against a penny.
Keep your spare CR2016 cells in their original blister pack. If you must remove them, store them in a plastic bag or separate container.
I also see people buying the cheapest multipack online without checking reviews. Low prices often mean old stock that has been sitting in a warehouse for years.
Those batteries might look fine, but the chemical shelf life is ticking down. You are not saving money if half the pack is dead on arrival.
Spend the extra dollar for fresh batteries from a reputable seller. Your devices will thank you.
When you have already wasted money on dead batteries and just want something that actually works, these are the ones I personally buy now to stop the frustration.
The Simple Test That Saved Me Dozens of Dead Batteries
Here is the trick that changed everything for me. I now test every CR2016 battery the second I open the package.
I keep a small multimeter in my kitchen drawer right next to where I store my spare batteries. It takes me five seconds to check a cell.
A fresh battery should read between 3.0 and 3.2 volts. Anything below 2.8 volts goes straight into the recycling bin.
I used to think testing was unnecessary. I assumed new meant working. Now I know better.
I have found dead batteries in brand new packs from major retailers. The packaging was sealed and the expiration date was years away, but the cell was empty.
Testing immediately means I can return the bad pack while I still have the receipt. Waiting a month makes that return much harder.
The real “aha” moment for me was learning that battery self-discharge happens even on the shelf. A battery can lose power sitting in a warehouse for a year.
That is why some cells in the same pack work fine while others are dead. They all age differently depending on storage conditions.
Testing each one is the only way to know for sure. Do not trust the package. Trust your multimeter.
My Top Picks for CR2016 Batteries That Actually Work

Frequently Asked Questions about Why Are Some CR2016 Lithium Coin Batteries Dead when I Test Them Immediately?
Can a brand new CR2016 battery really be dead right out of the package?
Yes, absolutely. I have personally opened sealed blister packs where one or two cells tested at zero volts.
This happens because batteries slowly self-discharge during storage. A battery sitting on a shelf for a year can lose significant power.
How long do CR2016 batteries last on the shelf before going bad?
Most manufacturers say these batteries last about three to five years from the production date. That is only true if stored properly.
Heat and humidity speed up the self-discharge process. A battery stored in a hot garage might die in under a year.
What is the best CR2016 battery for someone who needs one that works every time?
If you are tired of dead batteries ruining your day, I understand completely. That frustration is exactly why I switched to a brand I trust completely.
For a consistent experience, I personally recommend the ones I rely on for all my key fobs because they always test above 3.0 volts fresh out of the pack.

Does the brand of CR2016 battery affect how often they arrive dead?
In my experience, yes, brand matters a lot. Cheap no-name brands are much more likely to have dead cells in the pack.
Well-known brands have better quality control and fresher stock. Spending a little more upfront saves you from wasted batteries later.
Which CR2016 battery won’t let me down when I need it for my car key fob?
I know that feeling of standing in a parking lot pressing a dead fob button. That is a stressful moment nobody wants to repeat.
For my own car, I only use what I grabbed for my own key fob emergency kit because they have never let me down when I needed them most.

How can I test if my CR2016 battery is good without special tools?
Unfortunately, there is no reliable way to test these batteries without a multimeter. Your eyes cannot tell if a cell is dead.
You can try putting the battery in a device that uses a very small amount of power. But a multimeter is the only accurate test.
