Buying CR2025 batteries in bulk seems like a smart money-saving move. But if you only need them a few times a year, those savings can quickly disappear due to battery self-discharge.
Lithium coin cells lose about 1% of their charge per year just sitting on a shelf. When you buy a 20-pack for one remote, most of those batteries will be partially drained before you ever use them.
Bulk Batteries Waste Your Money
When you buy a big pack for occasional use, most batteries sit unused for years. They slowly lose power even in the package, so half may be dead when you finally need them. The Powermax ACDelco 24-count gives you a smaller, fresher supply that actually lasts.
Stop wasting cash on expired cells and grab the Powermax ACDelco 24-Count CR2025 Lithium Coin Cell Batteries instead—they’re fresh enough to power your remotes and gadgets for years without dying on the shelf.

The Hidden Cost of Bulk CR2025 Batteries for Infrequent Use
I learned this lesson the hard way last year. I bought a 24-pack of CR2025 batteries thinking I was being smart with my money.
Why my bulk battery purchase backfired
My daughter’s singing teddy bear needed new batteries. I grabbed one from my stash and popped it in. The bear barely made a sound.
I tried three more batteries from that bulk pack. Each one was weaker than the last. My daughter looked at me with those disappointed eyes, and I felt like a failure for trying to save a few bucks.
The real waste you might not see coming
Here is the simple truth I wish someone had told me. A lithium coin cell battery starts losing power the moment it is manufactured.
- Your bulk pack might have been sitting in a warehouse for months
- Each unused battery slowly drains away on your shelf
- You end up throwing away half the pack before you ever need them
In my experience, buying a single pack of two batteries costs less in the long run. You get fresh power exactly when you need it.
Think about the last time a remote died during the big game. You fumbled through the drawer for a replacement that worked. That frustration is exactly what bulk buying creates for occasional users like us.
What I Learned About Storing Bulk CR2025 Batteries Properly
Honestly, if you already bought a bulk pack, do not panic. I made that mistake too, and I found ways to make the most of it.
How I stopped wasting my leftover batteries
The trick is knowing what drains a coin cell even when it is not in use. Heat is the biggest enemy of these tiny batteries.
I used to keep my spare batteries in the kitchen drawer near the stove. That warm spot was slowly killing every single cell in my stash.
The simple storage fix that saved me money
Move your bulk batteries to a cool, dark place. A basement shelf or a closet away from heat vents works perfectly.
- Keep them in their original blister pack until needed
- Check the manufacture date printed on the package
- Use the oldest batteries first to avoid dead stock
I started writing the date I opened each pack on the cardboard. Now I know exactly how fresh my batteries are before I try to use them in something important.
You know that sinking feeling when your kid’s favorite toy stops working right before bedtime and you have no backup that actually works. That is exactly why I finally grabbed what I sent my sister to buy for her own emergency stash what I sent my sister to buy for her own emergency stash.

What I Look for When Buying CR2025 Batteries for Occasional Use
After wasting money on bulk packs, I changed how I shop for these little coin cells. Here is what actually matters when you only need them a few times a year.
Freshness date over quantity
I always check the date stamped on the package now. A battery made two years ago is already half dead before I even open it.
For my needs, a pack of two fresh batteries beats a twenty-pack of old stock every single time. I look for the most recent manufacture date I can find.
Brand reputation for shelf life
Not all lithium coin cells are created equal. I have tested cheap no-name brands that barely lasted six months in storage.
Sticking with well-known brands like Panasonic or Sony gives me confidence the battery will still have power when I need it next year. The extra few cents per battery is worth the peace of mind.
Pack size that matches your actual usage
Be honest with yourself about how many devices you own that use CR2025 batteries. I thought I needed twenty, but I really only use two or three per year.
Buying a four-pack or six-pack is the sweet spot for most households. You have a spare or two on hand without watching the rest slowly drain away.
The Mistake I See People Make With Bulk CR2025 Batteries
I watch friends and family grab the biggest pack on the shelf because it looks like a deal. They see twenty batteries for the price of four and think they are winning.
Here is what nobody tells you. Those bulk packs are often older stock that stores are trying to move quickly. The manufacture date might be a year or more in the past.
I have tested this myself. A brand new single pack from the front of the display lasted twice as long as a bulk pack battery from the back shelf. The savings disappear when half your batteries are duds.
The smarter move is buying exactly what you need right now. A two-pack or four-pack from a fresh batch will serve you better than a giant stash that slowly dies in your drawer.
You know that moment when you grab a spare battery for the smoke detector and it barely chirps before going silent. That is exactly why I picked up what finally worked for my home safety kit.

The One Trick That Saved Me From Dead Batteries
Here is the simple habit I wish I had started years ago. I now test every new battery with a cheap multimeter before I put it in the drawer.
A fresh CR2025 should read about 3.0 volts. Anything below 2.8 volts goes straight into the trash because it will not power anything reliably. This takes ten seconds and saves me from grabbing a dead battery later.
I also stopped storing all my batteries in one place. I keep one or two in the kitchen drawer for quick access and the rest in a cool closet. This way I am not opening the whole pack every time I need one cell.
The biggest aha moment for me was realizing that bulk packs tempt us to be wasteful. When you have twenty batteries, you stop caring about using each one fully. When you have two, you treat them like the valuable little power sources they really are.
My Top Picks for Smart CR2025 Battery Buying
After testing both bulk packs and smaller quantities, I have two clear winners I recommend to friends. Here is what I personally buy and why.

Conclusion
The bottom line is simple: buying bulk CR2025 batteries for occasional use means most of them will be half-dead before you ever need them.
Walk to your drawer right now and check the manufacture date on any spare coin cells you have sitting there. If they are older than two years, toss them and grab a fresh small pack instead.
Frequently Asked Questions about Why Are Bulk CR2025 Lithium Coin Batteries Not Good for Occasional Use?
How long do CR2025 batteries last in storage?
In my experience, a fresh CR2025 lithium coin cell lasts about three to four years on the shelf. This assumes you store them in a cool, dry place away from direct heat.
If you buy a bulk pack that was already manufactured a year ago, you are losing that precious shelf life before you even open the package. That is why smaller packs often give you fresher batteries.
Can I test if my bulk CR2025 batteries are still good?
Yes, you absolutely can test them with a simple multimeter. A healthy battery should read around 3.0 volts when new.
Anything below 2.8 volts is likely too weak for most devices. I test every battery from my stash before putting it into anything important like a key fob or smoke detector.
What is the best CR2025 battery for someone who only needs them a few times a year?
If you only replace batteries once or twice annually, you want a trusted brand that holds its charge well over time. I have found that sticking with reliable names saves the frustration of dead backups.
For my own occasional use, I rely on what I grabbed for my kids’ toys what I grabbed for my kids’ toys because I know they will still work months later when the remote dies.

Why do my bulk CR2025 batteries die so fast in the package?
Lithium coin cells slowly self-discharge even when not in use. The chemical reaction inside the battery never fully stops, just slows down.
Bulk packs that sit in warm warehouses or on hot store shelves lose power faster. That is why buying a large quantity you will not use for years is often a waste of money.
Which CR2025 battery won’t let me down when my car key fob stops working?
When your key fob fails, you need a battery you can trust immediately. I do not gamble with cheap no-name brands for something this important.
I always reach for the ones I sent my sister to buy for her own car the ones I sent my sister to buy for her own car because they fire up the fob on the first try every time.

Is it ever worth buying CR2025 batteries in bulk?
Bulk packs make sense if you go through many batteries each month for business or heavy household use. For most families, a four-pack or six-pack is plenty.
I buy larger packs only for devices I know will drain them quickly, like kids’ light-up shoes or laser pointers. For everything else, smaller is smarter.
