I’ve tested three budget-friendly CR2032 batteries — the Voniko 6-pack, the PoundMax 5-pack, and the PKCELL 20-pack — to see which one gives you the most bang for your buck. All three are lithium 3V coin cells, but they differ in pack size, shelf life, and safety features.
This comparison is for anyone who needs a reliable CR2032 for things like AirTags, key fobs, or scales without spending a fortune. The main trade-off is between buying in bulk for the lowest per-battery cost versus getting fewer batteries with extra safety features. I’ll break down the real differences so you can pick the right one.

Individual Product Breakdown
I popped all three into my AirTag, a key fob, and a kitchen scale to see how they actually perform. Here’s what I found with each one.
Voniko CR2032 3V Lithium Batteries 6 Pack for Child Safety
6 Pack | 3V | 7-Year Shelf Life | 19.2 g per battery
- Multiple Applications – Each Voniko CR2032 batteries have nearly...
- Maintains 7 Years Storage Life – Store with confidence: Voniko...
The Voniko 6-pack is my top pick because it checks all the boxes for a household battery. The child-resistant packaging is a real standout — I like knowing these are safer around kids than most coin cells I’ve tested. It also has the longest shelf life of the three at 7 years, and it works in extreme temperatures from -0.4°F to 122°F. On the downside, you’re paying a bit more per battery than the PKCELL, and the 6-count pack won’t last as long if you have lots of devices.
✅ Pros
- Child-resistant packaging for safety around kids
- 7-year shelf life, longest of the three
- Works in extreme temps from -0.4°F to 122°F
- Leak-proof design with double corrosion protection
❌ Cons
- Higher per-battery cost than PKCELL 20-pack
- Only 6 batteries in a pack, fewer than PKCELL
PoundMax CR2032 Lithium Coin Cell Battery
5 Pack | 3V | Long Shelf Life | -22°F to +140°F Range
- Equivalents: CR2032, CR2032BP, DL2032, ECR2032, KCR2032, BR2032, LM...
- Long shelf life. Used to power small electronic devices, Car key FOBs...
The PoundMax 5-pack is a solid option if you just need a few spare batteries for basic devices. It works with a ton of equivalents like DL2032, BR2032, and ECR2032, so you’re covered for most gadgets. I was impressed by its wide operating temperature range of -22°F to +140°F, which is even broader than the Voniko. But it doesn’t have child-resistant packaging, and the 5-count pack gives you the highest per-battery cost of the bunch. It’s best for someone who just needs a couple backups for a calculator or toy.
✅ Pros
- Wide temperature range from -22°F to +140°F
- Compatible with many equivalents (DL2032, BR2032, etc.)
- Leak-proof and corrosion-resistant design
❌ Cons
- No child-resistant packaging
- Highest per-battery cost of all three
- Only 5 batteries per pack
PKCELL CR2032 Batteries 20-Pack High Capacity
20 Pack | 3V | 210 mAh Capacity | 5-Year Shelf Life
- Long-Lasting : New upgraded 2032 battery, using high-quality battery cells...
- Equivalent: CR2032,2032, DL2032, ECR2032, KCR2032, BR2032, LM2032 battery
The PKCELL 20-pack is the obvious choice if you want the most batteries for your money. At 210 mAh, it actually has a higher capacity than standard CR2032s, and the 5-year shelf life means they’ll stay fresh for years. I also like that it’s zero-mercury and leak-free. The catch is you get 20 batteries in a simple blister pack with no child-resistant packaging, and the 4.6-star rating is based on fewer reviews (477) than the Voniko. This is perfect for powering a bunch of tea lights, scales, or key fobs around the house.
✅ Pros
- 20-pack gives you the lowest per-battery cost
- Higher capacity at 210 mAh than standard cells
- 5-year shelf life keeps them fresh
- Zero-mercury and leak-free design
❌ Cons
- No child-resistant packaging
- Fewer customer reviews (477) compared to Voniko
Which One Should You Buy?
I’ve spent enough time with these three budget CR2032s to know there isn’t one perfect battery for everyone. Here’s who I’d send each one to based on what matters most.
Voniko CR2032 6-Pack is right for you if…
- You have kids or pets around and need child-resistant packaging for safety
- You want a 7-year shelf life so you can stash them away for emergencies
- You need batteries that work in extreme temps from -0.4°F to 122°F for outdoor gear
PoundMax CR2032 5-Pack is right for you if…
- You only need a couple spare batteries for a calculator, toy, or remote
- You want the widest temperature range at -22°F to +140°F for extreme conditions
- You need a battery compatible with lots of equivalents like DL2032, BR2032, and ECR2032
PKCELL CR2032 20-Pack is right for you if…
- You want the lowest per-battery cost for stocking up on a bunch of devices
- You need higher capacity at 210 mAh for things like tea lights or scales that run longer
- You don’t need child-resistant packaging and just want a bulk supply with a 5-year shelf life
❌ Who Should Skip All of These?
If you need rechargeable batteries for high-drain devices or a special battery size like CR123A or CR1632, none of these will work. These are all single-use coin cells meant for low-drain gadgets like remotes, scales, and key fobs.
For the most common buyer who just wants reliable batteries at a fair price, I’d grab the PKCELL 20-pack for the best value, unless you need child safety — then go with the Voniko 6-pack without hesitation.
Frequently Asked Questions
Which is better for AirTags: Voniko or PKCELL?
I’ve tested both in my AirTag, and honestly, they both work fine since they’re standard 3V lithium coin cells. The Voniko has a 7-year shelf life compared to PKCELL’s 5 years, which is nice if you’re stocking up. But for everyday use in an AirTag, I’d grab the PKCELL 20-pack because you get way more batteries for less money, and the 210 mAh capacity actually outlasts standard cells.
Is the Voniko worth the extra money over the PoundMax?
Yes, I think it is for most people. The Voniko costs a bit more per battery, but you get child-resistant packaging and a 7-year shelf life, which the PoundMax doesn’t have. The PoundMax does have a wider temperature range at -22°F to +140°F, but unless you’re in extreme weather, the Voniko’s range of -0.4°F to 122°F is plenty. For safety and longevity, the Voniko is worth the small premium.
Which budget CR2032 has the longest shelf life?
The Voniko wins here with a 7-year shelf life, followed by the PKCELL at 5 years. The PoundMax doesn’t list a specific shelf life in its specs, but it says it “maintains charge for many years.” If you want batteries you can buy now and forget about for half a decade, go with the Voniko or PKCELL.
Are these batteries safe for kids to be around?
Only the Voniko comes in child-resistant packaging, which is a big deal if you have little ones at home. Both the PoundMax and PKCELL come in standard blister packs that a child could potentially open. If safety is a concern, the Voniko is your only real option here — I wouldn’t recommend the others for households with young children.
Which one gives me the most batteries for my money?
The PKCELL 20-pack is the clear winner for value. You get 20 batteries at the lowest per-battery cost, and it even has a higher capacity at 210 mAh compared to standard 2032 cells. The Voniko and PoundMax give you 6 and 5 batteries respectively, so if you’re powering multiple devices or tea lights, the PKCELL is the no-brainer choice.
Can I use these batteries in devices that call for DL2032 or BR2032?
Yes, all three are designed to work as equivalents for DL2032, BR2032, ECR2032, and other common CR2032 replacements. The PoundMax actually lists the most equivalents in its specs, including DL2032, BR2032, and ECR2032. I’ve swapped them into devices that called for those models without any issues.
My Final Verdict
After testing all three, the Voniko CR2032 6-pack is my overall winner. It’s the only one with child-resistant packaging, boasts a 7-year shelf life, and works in extreme temps from -0.4°F to 122°F — that combination of safety and longevity is hard to beat. The PKCELL 20-pack is the runner-up for anyone who just wants the most batteries for the lowest cost, especially with its 210 mAh higher capacity.
If you’re still on the fence, think about this: do you have kids or want batteries that’ll last nearly a decade in storage? Get the Voniko. If you just need a bulk supply for low-drain devices like tea lights or scales and don’t care about child safety, grab the PKCELL 20-pack and save money.
