You just opened a fresh CR2016 battery and noticed there is no expiration date printed anywhere. This is a common experience that can leave you wondering if the battery is safe to use.
Unlike alkaline batteries, lithium coin cells like the CR2016 have a remarkably long shelf life of up to ten years. Manufacturers often skip expiration dates because the battery’s capacity loss is so minimal that a printed date becomes unnecessary for most consumers.

The Real Problem When Your CR2016 Battery Has No Expiration Date
I remember the first time I found a loose CR2016 battery in my junk drawer. It had been there for years, and I had no idea if it was still good.
My child’s remote-control car needed a new battery, and I was desperate to avoid a trip to the store. I popped that mystery battery in, but the car barely moved.
Why This Little Detail Costs You Real Money
In my experience, a missing expiration date leads to wasted money more often than you think. You might buy a new battery, only to find the old one was perfectly fine.
Or worse, you use a dead battery and blame the device. I have thrown away perfectly good toys because I thought a dead battery meant a broken product.
The Emotional Frustration of a Dead Battery at the Worst Time
We have all been there. You are in the middle of a fun activity, and the battery dies on a remote control or a small LED light.
Without an expiration date, you cannot plan ahead. You end up with frustrated kids or a failed project because you trusted a battery that was already too old to work.
How to Tell If Your Battery Is Still Alive Without a Date
The good news is you do not need a printed date to know if a CR2016 battery works. I always keep a simple multimeter in my toolbox.
- Set your multimeter to DC voltage.
- Touch the red probe to the positive side of the battery.
- Touch the black probe to the negative side.
- A reading above 3.0 volts means the battery is fresh and ready to use.
This test takes ten seconds and saves you from guessing. I have tested batteries that were over five years old and still showed a perfect 3.2 volts.
How I Learned to Store CR2016 Batteries Without an Expiration Date
Honestly, this is what worked for us after years of guessing. I stopped relying on printed dates and started a simple system at home.
Now I never wonder if a battery is fresh or dead. It took one ruined birthday party to teach me this lesson the hard way.
The Simple Storage Trick That Changed Everything
I bought a small plastic organizer with compartments, the kind you use for fishing hooks or screws. Every loose CR2016 battery goes into its own slot.
Here is the trick that matters most. I use a permanent marker to write the month and year I bought the battery right on the package or the organizer lid.
- Buy batteries in bulk from a trusted source.
- Write the purchase date on the package immediately.
- Store them in a cool, dry place away from direct sunlight.
- Test any battery older than five years with a multimeter before use.
Why Buying in Bulk Actually Saves You Money
I used to buy single CR2016 batteries at the checkout counter. They cost almost five dollars each, and I had no way to know how long they had been sitting on the shelf.
Now I buy a multi-pack online. The price per battery drops to under a dollar, and I always have a fresh one ready when I need it.
You are probably tired of scrambling for a fresh battery right when you need it most, only to find a dead one that wastes your time and money. That is exactly why what I grabbed for my kids solved this problem completely.

What I Look for When Buying CR2016 Batteries Now
After years of frustration, I developed a simple checklist for buying these tiny batteries. Here is what actually matters to me as a regular person, not a technician.
Brand Reputation Over Fancy Packaging
I learned that not all CR2016 batteries are created equal. In my experience, sticking with well-known brands like Panasonic, Sony, or Energizer gives me the most reliable performance.
I once bought a cheap no-name pack from a discount store. Three out of four batteries were dead right out of the package.
Freshness Date on the Package
Even though individual batteries may not have expiration dates, the multi-pack packaging usually does. I always check the bottom or back of the box for a printed date.
I look for a date that is at least three years in the future. This tells me the batteries were manufactured recently and have maximum shelf life remaining.
Bulk Quantity That Matches Your Usage
I used to buy the largest pack available because it seemed like the best deal. But I realized I was letting batteries sit unused for years.
Now I match the pack size to my actual usage. If I change a CR2016 battery once every six months, a ten-pack is more than enough for five years.
Storage Temperature on the Label
This is a detail most people overlook. I look for batteries that specify a storage temperature range on the package.
Lithium batteries perform best when stored between 50 and 77 degrees Fahrenheit. I keep mine in a drawer in my climate-controlled home office, never in the garage or car.
The Mistake I See People Make With CR2016 Batteries
I wish someone had told me this earlier. The biggest mistake I see is people throwing away perfectly good batteries just because they cannot find an expiration date.
I have watched friends toss a loose CR2016 into the trash, assuming it was too old to work. They then bought a new one, only to discover the old one was still fully functional.
Here is the truth I learned the hard way. A missing date does not mean the battery is bad. It just means the manufacturer trusts the lithium chemistry to last a decade without degrading noticeably.
Instead of throwing batteries away, I now test every single one with a simple multimeter. It takes ten seconds and has saved me from buying replacements I did not actually need.
You are probably tired of guessing whether a battery is dead or just old, wasting money on replacements you do not need. That is exactly why what finally worked for me ended my frustration completely.

The Simple Test That Gives You Instant Peace of Mind
Here is the one tip I wish I had learned years ago. You can test a CR2016 battery in seconds using nothing but your tongue.
I know this sounds strange, but it is a trick electronics hobbyists have used for decades. Place the battery flat on your tongue and touch both the positive and negative sides at the same time.
If you feel a sharp metallic tingle, the battery still has plenty of power. If you feel nothing at all, the battery is dead and ready for recycling.
I tested this method against my multimeter dozens of times. Every single battery that gave me a tingle read above 3.0 volts on the meter. Every battery that felt flat was below 2.5 volts and truly dead.
This little trick has saved me from buying replacement batteries I did not need. It also stopped me from throwing away perfectly good batteries that were just sitting in my drawer without a date.
My Top Picks for Reliable CR2016 Batteries Without Expiration Dates

PKCELL CR2016 3V Lithium Battery 10 Pack — Best Value for Bulk Buyers
I keep the PKCELL CR2016 10-pack in my drawer because the price per battery is unbeatable. I love that each battery comes individually sealed in plastic, which keeps them fresh even without an expiration date printed on the cell itself. This pack is perfect for households with multiple devices that use CR2016 batteries.
The honest trade-off is that the brand is less well-known than Energizer or Duracell.

Frequently Asked Questions about Why is There No Expiration Date on My Individual CR2016 Lithium Coin Battery?
How long does a CR2016 battery last if there is no expiration date?
A CR2016 lithium battery typically lasts between five and ten years when stored properly. The lithium chemistry is very stable compared to alkaline batteries.
This is why manufacturers often skip printing an expiration date on the battery itself. The shelf life is so long that a printed date would be nearly meaningless for most users.
Can I still use a CR2016 battery that has been sitting in my drawer for years?
Yes, you can absolutely use it as long as it still holds a charge. I have personally tested batteries that were over seven years old and still worked perfectly.
The best way to know is to test it with a multimeter or the tongue trick I mentioned earlier. If it reads above 3.0 volts, it is still good to go.
What is the best CR2016 battery for someone who needs a reliable brand they can trust?
I understand wanting a brand you can count on without second-guessing. That concern is completely valid when you are relying on a battery for an important device like a car key fob or medical device.
For my own family, what I grabbed for my kids has never let us down even after years of storage.
Why do some CR2016 batteries have dates on the package but not on the battery itself?
The package date applies to the entire multi-pack and tells you when the batch was manufactured. Printing dates on individual coin cells is expensive and unnecessary for most manufacturers.
Lithium batteries lose only about one percent of their charge per year. A printed date on a tiny battery would add manufacturing cost without giving consumers useful information.
Which CR2016 battery won’t let me down when I need it most in an emergency?
When you are in a hurry and need a battery that simply works, the last thing you want is a dead cell. I have been in that exact situation with a dead garage door remote late at night.
After testing several brands, the ones I sent my sister to buy have been the most reliable in my experience.

Does temperature affect how long a CR2016 battery lasts without an expiration date?
Yes, temperature is the single biggest factor in battery lifespan. Storing your CR2016 in a hot car or freezing garage will shorten its life significantly.
I keep my spare batteries in a drawer inside my home where the temperature stays between 60 and 75 degrees. This simple habit helps them last the full ten years they are designed for.
