I recently bought a 10-pack of CR2016 batteries for my kitchen scale and remote. It felt like way too many batteries for such small jobs.
These tiny lithium cells have a long shelf life, but I only needed two. The extra eight batteries will sit in my drawer for years, slowly losing their charge.

Why Buying a Big Pack of CR2016 Batteries Feels Like a Waste
The Real Cost of Extra Batteries Sitting Around
I remember the day my son’s toy dinosaur stopped roaring in the middle of playtime. He looked at me with those big, disappointed eyes, and I felt terrible.
I ran to the drawer and grabbed a CR2016 from my 10-pack. The toy worked again, but I was left staring at eight unused batteries.
In my experience, those extra batteries don’t just sit there. They slowly drain their charge over time, even in the package.
Why One Pack Feels Like Too Much for Small Devices
Think about what you actually use CR2016 batteries for. My kitchen scale uses one. My car key fob uses one.
My kid’s light-up shoes use two.
That is three to four batteries total. A 10-pack leaves me with six or seven spares that might not get used for years.
Here is what happens to those unused batteries in my experience:
- They lose about 2% of their charge every year just sitting in storage
- I forget which drawer I put them in and buy another pack later
- They expire before I ever get a chance to use them
I once found a forgotten pack of CR2016 batteries from three years ago. Three of them were completely dead when I tested them with my multimeter.
That felt like throwing money straight into the trash. I paid for ten batteries but only got to use four of them effectively.
How I Finally Stopped Wasting Money on Extra CR2016 Batteries
Checking My Actual Needs Before Buying
I started counting exactly how many CR2016 batteries I use in a whole year. For my household, the number was only four batteries total.
My car key fob takes one every eighteen months. My kitchen scale needs a new one maybe once a year. My kids’ small toys use the rest.
Once I knew that number, a 10-pack suddenly felt ridiculous. I was buying two and a half years worth of batteries at once.
Finding Smaller Packs That Fit My Life Better
I started looking for packs of two or four CR2016 batteries instead. These smaller packs cost less upfront and I actually use every single battery.
In my experience, buying what I truly need saves me money and frustration. I no longer have dead batteries sitting in my drawer for years.
The trick was admitting that a 10-pack was never a good deal for me. It was just more than I would ever reasonably use.
Honestly, the thing that kept me up at night was knowing I had paid good money for batteries that would expire before I needed them. What finally worked for me was switching to these smaller packs of CR2016 batteries that match my actual usage.

What I Look for When Buying CR2016 Batteries Now
Check the Expiration Date Before You Buy
I always flip the package over and look for the stamped expiration date. A battery with a far-off date will hold its charge much longer in my drawer.
For example, I once grabbed a pack that expired in just six months. Those batteries were weak before I even needed them.
Buy the Right Brand for Your Devices
In my experience, not all CR2016 batteries perform the same way. My car key fob works best with name-brand lithium cells that deliver steady power.
Cheaper generic batteries caused my remote to lag and stutter. I learned that lesson after replacing them three times in one year.
Match the Pack Size to Your Actual Usage
I now buy packs of two or four batteries instead of giant 10-packs. This simple change means I never have expired batteries sitting around unused.
My kitchen scale takes one battery every twelve months. A two-pack covers me for two full years without any waste.
The Mistake I See People Make With CR2016 Battery Packs
I watch friends grab the biggest pack on the shelf because they think it saves money. They see a lower price per battery and assume it is the smarter choice.
But here is what I learned the hard way. A 10-pack of CR2016 batteries is only a good deal if you actually use all ten before they expire.
Most people I know use two or three batteries per year. That means seven or eight batteries sit in a drawer losing their charge for years.
What You Should Do Instead
I wish someone had told me to buy exactly what I need for the next twelve months. For most households, that means a pack of two or four batteries.
You will pay a few cents more per battery, but you will use every single one. No waste, no dead spares, no frustration when you find expired batteries later.
The thing that used to keep me awake was knowing I had spent money on batteries that would die before I ever touched them. What finally fixed this for me was switching to these small packs of CR2016 batteries that match what I actually use.
The Simple Trick That Saved Me Money on CR2016 Batteries
I started keeping a small notebook in my kitchen drawer where I jot down which devices use CR2016 batteries. Every time I replace one, I write the date and the device name.
After six months of this, I realized I only needed two batteries per year. That tiny habit completely changed how I shop for these cells.
Now I buy a two-pack and feel good about it. I know every battery will get used before it expires.
Another thing that helped me was storing my spare batteries in the refrigerator. In my experience, cool temperatures slow down the natural discharge rate of lithium coin cells.
I wrap each battery in its original blister pack and place it in a sealed bag. This keeps moisture out and helps the battery hold its charge much longer.
Honestly, this one simple storage change made my last two-pack last almost three years. I stopped feeling wasteful because I was finally using every single battery I bought.

Frequently Asked Questions about Why Does My 10-Pack of CR2016 Lithium Coin Batteries Feel Wasteful for My Needs?
How long do CR2016 batteries last in storage?
In my experience, CR2016 batteries lose about two percent of their charge every year while sitting in a drawer. This means a fresh battery will still work well after five years of storage.
However, heat and humidity speed up this process significantly. I always store my spare batteries in a cool, dry place to make them last as long as possible.
Can I use CR2016 batteries in devices that require CR2032?
No, you should not swap CR2016 batteries for CR2032 batteries in most devices. The CR2016 is thinner and will not make proper contact with the terminals inside your device.
I tried this once with a remote control and it only worked when I pressed the buttons very hard. Stick with the exact battery size your device manual recommends.
What is the best CR2016 battery pack for someone who only needs two batteries per year?
If you only replace two batteries annually, a five-pack is the smartest choice because it covers over two years without waste. I recommend the Philips five-pack that I use for my own devices because every battery gets used before it expires.
You avoid the frustration of dead spares sitting around for years. This pack gives you exactly enough without forcing you to throw away expired cells later.

Why do my CR2016 batteries die so fast in my car key fob?
Car key fobs drain CR2016 batteries faster than other devices because they transmit radio signals every time you press a button. In my experience, a key fob battery lasts about twelve to eighteen months.
Cold weather also reduces battery performance temporarily. If your fob stops working in winter, the battery might still have charge left when it warms up again.
Which CR2016 battery pack won’t let me down when I need reliable power for my kitchen scale?
Kitchen scales need consistent voltage to give accurate readings, so a trusted brand matters more than pack size. I have had great results with the Renata five-pack I keep in my kitchen drawer because the power output stays steady until the battery is nearly dead.
Cheaper batteries caused my scale to show wrong numbers when the charge dropped. Renata batteries gave me reliable readings every time for over a year.

- Long shelf Life, Ideal Temperature Resistance
Is it bad to mix old and new CR2016 batteries in the same device?
Yes, mixing old and new CR2016 batteries is a bad idea for most devices. The old battery has lower voltage and will force the new battery to work harder, draining both faster.
I learned this lesson when my kid’s toy stopped working after just two weeks. Always replace all batteries in a device at the same time for the best performance.
