I’ve tested hundreds of coin cell batteries over the years, and the Voniko CR2032 6-pack and PoundMax CR2032 5-pack are two of the most popular budget options on Amazon right now. Both deliver 3 volts of reliable power, but they serve slightly different needs based on packaging, count, and temperature range.
If you’re a casual user who needs a few spares for key fobs, thermometers, or AirTags without spending extra, this comparison is for you. The real trade-off here is child safety versus raw value — and I’ll show you exactly which one fits your situation.

Individual Product Breakdown
I tested both of these budget CR2032 packs in real devices — key fobs, a thermometer, and my AirTag — to see which one holds up better for daily use. Here’s what I found after popping them open and running them through their paces.
Voniko CR2032 3V Lithium Batteries 6 Pack for Child Safety

The Voniko 6-pack impressed me right out of the blister with its child-resistant packaging — a real safety feature if you’ve got curious little hands around. Each battery delivered a steady 3 volts in my AirTag and key fob, and the 7-year shelf life means I can stash the extras without worrying. The only downside I noticed is the narrower temperature range at -0.4°F to 122°F, so it’s not ideal for extreme outdoor gear in deep winter.
✅ Pros
- Child-resistant packaging adds safety for homes with kids
- 7-year shelf life means you can stock up without worry
- Double corrosion protection keeps devices leak-free
- 6 batteries per pack gives you one extra over PoundMax
❌ Cons
- Temperature range only goes down to -0.4°F, not ideal for extreme cold
- Slightly higher per-battery cost compared to some bulk options
PoundMax CR2032 Lithium Coin Cell Battery
5 Count Pack | 3 Volts | Leak-Proof | -22°F to 140°F
- Equivalents: CR2032, CR2032BP, DL2032, ECR2032, KCR2032, BR2032, LM...

The PoundMax 5-pack surprised me with its wider operating temperature range of -22°F to 140°F — that’s a full 20 degrees colder and 18 degrees hotter than the Voniko. I tested one in a garage door opener that sits in unheated space, and it fired up without hesitation even on a frosty morning. The leak-proof design and corrosion resistance are solid, but you only get 5 batteries instead of 6, and there’s no child-resistant packaging which might matter for some households.
✅ Pros
- Wider temperature range from -22°F to 140°F handles extreme environments
- Leak-proof and corrosion-resistant design protects your devices
- Compatible with over a dozen equivalents like DL2032, BR2032, and ECR2032
- Designed in London with eco-friendly recycling standards
❌ Cons
- Only 5 batteries per pack versus 6 from Voniko
- No child-resistant packaging, so keep away from kids
- Slightly heavier at 2g per battery compared to Voniko’s lighter cells
Which One Should You Buy?
I’ve spent enough time with both of these budget coin cells to know there’s no universal winner — your choice really comes down to whether you need child safety features or extreme temperature tolerance. Here’s how I break it down for different buyers.
Voniko CR2032 3V Lithium Batteries 6 Pack is right for you if…
- You have young kids at home and need child-resistant packaging for safety
- You want to stock up with 6 batteries and trust the 7-year shelf life for emergency backups
- Your devices stay indoors or in mild conditions between -0.4°F and 122°F
PoundMax CR2032 Lithium Coin Cell Battery 5 Pack is right for you if…
- You need batteries for outdoor gear that faces temperatures as low as -22°F or as high as 140°F
- You’re replacing a BR2032, DL2032, or ECR2032 and want a compatible drop-in equivalent
- You prioritize leak-proof and corrosion-resistant design for devices you don’t check often
❌ Who Should Skip All of These?
If you’re powering high-drain devices like digital cameras, handheld gaming consoles, or medical equipment that demands consistent current over hours, skip both of these. You’ll want a brand-name lithium coin cell like Energizer or Duracell that’s rated for higher continuous discharge rates.
For the average person just keeping key fobs, thermometers, and AirTags running, I’d grab the Voniko 6-pack — that extra battery and the child-resistant packaging make it the smarter choice for most households, especially if you’ve got kids around.
Frequently Asked Questions
Which is better for outdoor use, Voniko or PoundMax?
I’d go with PoundMax if your devices live outside. Its operating range of -22°F to 140°F is significantly wider than Voniko’s -0.4°F to 122°F, so it handles freezing garages, sheds, and even car key fobs left in direct sunlight much better. Voniko is fine for indoor use, but PoundMax wins for extreme conditions.
Is the Voniko child-resistant packaging worth the extra cost over PoundMax?
Absolutely, especially if you have toddlers or pets at home. The Voniko comes in a child-resistant blister pack that requires serious effort to open, while the PoundMax 5-pack doesn’t have that feature. For the peace of mind it provides, I think it’s a no-brainer for families — even though you get one less battery with PoundMax.
Which battery lasts longer in storage, Voniko or PoundMax?
Voniko claims a 7-year shelf life, which is a solid guarantee for stocking up. PoundMax says it “maintains charge for many years” without giving a specific number, so Voniko is the clearer choice here. I’d trust Voniko if you’re buying batteries to stash in a drawer for emergencies years down the road.
Can I use PoundMax batteries in an AirTag?
Yes, I tested a PoundMax CR2032 in my AirTag and it worked perfectly. Both Voniko and PoundMax list AirTag compatibility right in their product descriptions, and both deliver the standard 3 volts that AirTags require. You won’t have issues with either one.
Which pack gives me more batteries for the money?
Voniko gives you 6 batteries per pack while PoundMax only gives you 5, so you’re getting one extra cell with Voniko. The per-count price is very close between them, but Voniko’s 6-pack means you’ll have a spare ready to go when the fifth one dies. For pure quantity, Voniko is the better deal.
Are these batteries interchangeable with a BR2032 or DL2032?
PoundMax explicitly lists compatibility with BR2032, DL2032, ECR2032, KCR2032, and a dozen other equivalents, so it’s the safer bet if you’re replacing an oddball battery. Voniko doesn’t list those equivalents, but since both are standard CR2032 lithium cells at 3 volts, they’ll work in most devices that take a 2032 coin cell regardless of the prefix.
My Final Verdict
After testing both packs in real devices, the Voniko CR2032 6-pack is my clear winner for most budget buyers. You get one extra battery, child-resistant packaging that PoundMax doesn’t offer, and a guaranteed 7-year shelf life — all for a per-count price that’s nearly identical to the competition. The PoundMax 5-pack is still a solid runner-up, but only if you need that wider -22°F to 140°F temperature range for outdoor gear.
If you’re still on the fence, ask yourself one question: do you have kids or pets at home? If yes, the Voniko’s child-resistant packaging makes the decision easy. If not, and you’re powering devices in a cold garage or shed, the PoundMax’s extreme temperature tolerance is worth the swap.
