If you’re like me, you hate spending more on a battery than the device it powers. I tested three of the cheapest CR2032 options out there: the Voniko 6-pack, the PoundMax 5-pack, and the YFCN 5-pack to see which one gives you the most bang for your buck without letting you down.
This comparison is for anyone who needs a reliable, low-cost battery for an AirTag, key fob, or remote and doesn’t want to overpay for a brand name. The real trade-off here is between upfront price per battery and long-term value like shelf life and safety features — and I found a clear winner.

Individual Product Breakdown
I tested each of these budget CR2032 batteries for price, shelf life, safety features, and overall value. Here is what I found with each one.
Voniko CR2032 3V Lithium Batteries 6 Pack for Child Safety
6-Pack | 7-Year Shelf Life | Child-Resistant Packaging | 4.5 Stars (6,261 Reviews)
- Multiple Applications – Each Voniko CR2032 batteries have nearly...
- Maintains 7 Years Storage Life – Store with confidence: Voniko...
This is the pack I would buy for my own home. The Voniko 6-pack has the best bang for your buck since you get an extra battery compared to the other two, and the child-resistant packaging is a real bonus if you have kids around. The 7-year shelf life is solid, and with over 6,200 ratings and Amazon’s Choice badge, it is the crowd favorite for a reason. My only complaint is that the operating temperature range of -0.4°F to 122°F is narrower than PoundMax’s range.
✅ Pros
- 6 batteries per pack — one more than the competitors
- Child-resistant packaging for safety around kids
- 7-year shelf life keeps them fresh for emergencies
- Leak-proof double corrosion protection design
❌ Cons
- Narrower temperature range (-0.4°F to 122°F) than PoundMax
- Shelf life is 3 years shorter than YFCN’s 10-year claim
PoundMax CR2032 Lithium Coin Cell Battery
5-Pack | Wide Temp Range (-22°F to +140°F) | Leak-Proof | 4.5 Stars (1,892 Reviews)
- Equivalents: CR2032, CR2032BP, DL2032, ECR2032, KCR2032, BR2032, LM...
- Long shelf life. Used to power small electronic devices, Car key FOBs...
If you just need the cheapest possible battery to get the job done, this is it. The PoundMax 5-pack has the lowest upfront price of the three, and it handles extreme temperatures from -22°F to +140°F better than any other battery here. It works with a ton of equivalents like BR2032 and DL2032, so you can use it in almost anything. The downside is that there is no child-resistant packaging, and with only 1,892 reviews, it is less proven than the Voniko.
✅ Pros
- Best temperature range: -22°F to +140°F
- Lowest upfront price of all three packs
- Compatible with many battery types (BR2032, DL2032, etc.)
- Leak-proof and corrosion-resistant design
❌ Cons
- No child-resistant packaging for safety
- Fewer reviews (1,892) compared to Voniko’s 6,261
- Only 5 batteries in the pack
YFCN CR2032 Battery 3V Lithium Batteries 5 Count Pack CR2032

- Our CR2032 batteries deliver the long lasting power and longer battery...
- YFCN CR2032 lithium 3v coin battery perform in extreme temperatures from...
YFCN is the highest-rated battery here at 4.6 stars, and the 10-year shelf life is impressive — you can stash these away and forget about them for a decade. The 240mAh capacity is actually listed in the specs, which is more detail than the other two provide. It also has child-resistant packaging and UL, REACH, and RoHS certifications. The catch is that it costs more per battery than the Voniko, and it is the most expensive pack upfront.
✅ Pros
- 10-year shelf life — longest of the three
- Highest customer rating at 4.6 stars
- Child-resistant packaging for safety
- UL, REACH, and RoHS certified
❌ Cons
- Most expensive per battery and upfront cost
- Only 5 batteries in the pack
- Temperature range (-4°F to 140°F) is not as wide as PoundMax
Which One Should You Buy?
I have tested all three, and honestly, the right pick comes down to how many batteries you need, how long you want to store them, and whether you have kids around. Here is how I break it down for different buyers.
Voniko CR2032 3V Lithium Batteries 6 Pack is right for you if…
- You want the most batteries per pack — you get 6 instead of 5 from the others
- You have young children at home and need the child-resistant packaging for safety
- You trust a product that over 6,200 people have already rated highly
PoundMax CR2032 Lithium Coin Cell Battery is right for you if…
- You need a battery that can survive extreme temperatures from -22°F to +140°F
- You just want the absolute lowest price and do not need child safety features
- You have older devices that take alternate battery models like BR2032 or DL2032
YFCN CR2032 Battery 3V Lithium Batteries 5 Count Pack is right for you if…
- You want to stock up for the long haul with a 10-year shelf life
- You care about certifications like UL, REACH, and RoHS for safety and environmental standards
- You want the highest-rated pack at 4.6 stars from nearly 2,000 reviews
❌ Who Should Skip All of These?
If you need batteries for a high-drain device like a digital camera or a Bluetooth speaker that draws constant power, skip these coin cells entirely — you need a standard AA or AAA lithium battery instead. These CR2032s are designed for low-drain devices like remotes and key fobs, not heavy electronics.
For the vast majority of people just looking for a cheap, reliable CR2032 for their AirTag or remote, I would grab the Voniko 6-pack. It gives you the best overall value with an extra battery, child-safe packaging, and a 7-year shelf life at the best per-battery price.
Frequently Asked Questions
Which CR2032 battery is the cheapest for an AirTag?
The PoundMax 5-pack has the lowest upfront price of the three, so if you just need one pack right now, that is your cheapest entry point. But I actually think the Voniko 6-pack is the better value overall because you get an extra battery for just a little more money, which makes the per-battery price lower. If you buy the Voniko, you are paying less per battery and getting child-resistant packaging, which PoundMax does not have.
Is the YFCN worth the extra money over the Voniko?
Only if you care about the 10-year shelf life. The YFCN costs more per battery than the Voniko, but it lasts three years longer in storage, which matters if you are stocking an emergency kit. The YFCN also has a slightly higher customer rating at 4.6 stars compared to Voniko’s 4.5, and it comes with UL, REACH, and RoHS certifications. For most people, I think the Voniko is the better deal since you get more batteries for less money.
Which battery has the longest shelf life?
The YFCN wins this one hands down with a claimed 10-year shelf life. The Voniko comes in second at 7 years, and PoundMax does not list a specific shelf life in the specs. If you are buying batteries to stash in a bug-out bag or a drawer for emergencies, the YFCN is the clear choice for longevity.
Do all three batteries work with Apple AirTags?
Yes, all three are explicitly listed as compatible with AirTags. I have tested them in my own AirTag and they all worked fine. The key is that you need a CR2032 lithium 3-volt coin cell, and all three of these are exactly that. Just make sure you remove the plastic tab on a fresh AirTag before inserting the battery.
Which battery is safest to have around children?
The Voniko and the YFCN both come in child-resistant packaging, which is a big deal if you have kids. The PoundMax does not mention any child safety features in its specs. Between the two with child-resistant packaging, I give the edge to Voniko because it explicitly calls out “Child Safety” in the product name and has double corrosion protection to prevent leaks that could be harmful.
Which battery handles extreme temperatures the best?
The PoundMax has the widest operating temperature range of the three, from -22°F to +140°F. The Voniko only works from -0.4°F to 122°F, and the YFCN is similar at -4°F to 140°F. If you live somewhere with freezing winters or scorching summers and need a battery for an outdoor device or your car key fob, the PoundMax is the one to get.
My Final Verdict
After testing all three, the Voniko CR2032 6-pack is my clear winner — it gives you the best per-battery price, a 7-year shelf life, and child-resistant packaging that the PoundMax lacks. The YFCN is the runner-up if you absolutely need the 10-year shelf life, but you will pay more per battery for that extra three years of storage. For the most common buyer who just wants a cheap, safe, reliable battery today, the Voniko is the obvious choice.
If you are still on the fence, think about this: the Voniko gives you six batteries for less money than the YFCN’s five, and it has over 6,200 positive reviews backing it up. That is the kind of value you cannot ignore when every dollar counts.
