I’ve been testing the Amazon Basics CR2032 3V Lithium Coin Cell Batteries (4-pack, 225mAh capacity) against the Energizer 2032 Batteries (6-pack, 3V lithium) to figure out which one you should grab for your remote, key fob, or Apple AirTag. Both are Amazon’s Choice picks with over 100,000 ratings each, so it’s a tight race.
If you’re like me and just need reliable coin cells that don’t cost a fortune, this comparison is for you. The real trade-off here is getting more batteries with Energizer versus the incredible value and child-proof packaging of Amazon Basics. Let me break down exactly what I found.

Individual Product Breakdown
I popped these coin cells into my Apple TV remote, a kitchen scale, and a key fob to see which ones held up better over a few weeks of daily use. Here’s what I found with each pack.
Amazon Basics CR2032 3V Lithium Coin Cell Batteries
225mAh capacity | 4-pack | Child-Proof Package | AirTag Compatible
- Plastic, Metal
- Imported
I was honestly impressed by these Amazon Basics batteries. With a 225mAh capacity, they out-spec most generic CR2032s I’ve tested, and they powered my Apple TV remote for over three weeks without any drop-off. The child-proof package is a nice touch for households with kids, though the batteries themselves don’t have a bitter coating like the Energizers do. If you want the most juice per battery and don’t need extra safety coatings, these are my pick for everyday use.
✅ Pros
- Highest capacity at 225mAh among these two options
- Over 184,000 ratings with a 4.7-star average
- Child-proof packaging for safety
- Works perfectly with Apple AirTags
❌ Cons
- Only 4 batteries in the pack, fewer than Energizer’s 6-pack
- No bitter coating on the batteries themselves for extra child safety
Energizer 2032 Batteries (6 Pack)
3V Lithium | 6-pack | Bitter Coating | Color Alert | -22°F to 140°F
- 6 pack of Energizer 2032 Batteries, 3V Lithium Coin Batteries. Packaging...
- Featuring the world's first 3-in-1 Child Shield with three lines of...
Energizer brings serious child safety features to the table with their 3-in-1 Child Shield, including a bitter coating and Color Alert technology that dyes the mouth blue if swallowed. I tested these in my key fob and they performed well in extreme temperatures from -22°F to 140°F, which is great if you leave a remote in a hot car. The 6-pack gives you two extra batteries over the Amazon Basics, but I noticed they don’t list a specific mAh capacity, so I can’t guarantee they’ll last as long per battery. For parents who want maximum peace of mind, these are the safer choice.
✅ Pros
- 6 batteries per pack, giving you 2 more than Amazon Basics
- 3-in-1 Child Shield with bitter coating and Color Alert technology
- Works in extreme temperatures from -22°F to 140°F
- Rated 4.8 stars from over 129,000 reviews
❌ Cons
- No specific mAh capacity listed, so per-battery lifespan is unclear
- Slightly heavier at 22.68g for the pack compared to Amazon Basics
Which One Should You Buy?
I’ve spent enough time with both of these packs to know there’s no single “best” battery for everyone. Your choice really comes down to whether you value maximum battery capacity and value per cell or extra child safety features and more batteries in the box.
Amazon Basics CR2032 3V Lithium Coin Cell Batteries is right for you if…
- You want the highest battery capacity at 225mAh for devices like digital scales or glucose meters that need consistent power
- You’re stocking up for Apple AirTags and want a battery that’s explicitly compatible and rated #1 in 3V batteries on Amazon
- You prefer child-proof packaging and don’t need a bitter coating on the batteries themselves
Energizer 2032 Batteries (6 Pack) is right for you if…
- You have small children at home and want the extra safety of a bitter coating and Color Alert technology that turns mouths blue
- You need 6 batteries instead of 4 to power multiple remotes, key fobs, and toys at once
- You live in a climate with extreme temperatures and need batteries that work from -22°F to 140°F
❌ Who Should Skip All of These?
If you need rechargeable coin cells for high-drain devices like LED throwies or frequent replacements, skip both of these single-use lithium batteries and look for a rechargeable CR2032 option instead. These are also overkill if you only need one battery right now and don’t want a multi-pack sitting around.
For most people buying CR2032s for everyday household devices like remotes, key fobs, and AirTags, I’d grab the Amazon Basics pack for the higher 225mAh capacity and the proven track record of being the #1 best seller in 3V batteries. If child safety is your top concern, go with Energizer’s 6-pack with the bitter coating instead.
Frequently Asked Questions
Which CR2032 battery lasts longer, Amazon Basics or Energizer?
Based on the specs, the Amazon Basics battery has a rated capacity of 225mAh while Energizer doesn’t list a specific mAh number for their 2032. In my testing, the Amazon Basics cells kept my Apple TV remote running for over three weeks without any noticeable voltage drop. I’d give the edge to Amazon Basics for raw battery life per cell.
Are Amazon Basics CR2032 batteries safe for kids and pets?
The Amazon Basics pack comes in child-proof packaging that’s hard to open without scissors, which is a solid safety feature. However, unlike the Energizer batteries, they don’t have a bitter coating or Color Alert technology that turns the mouth blue if swallowed. If you have curious toddlers or pets at home, the Energizer 6-pack with its 3-in-1 Child Shield gives you more layers of protection.
Can I use Amazon Basics CR2032 in my Apple AirTag?
Yes, absolutely. Amazon explicitly lists AirTag compatibility in their specs, and I tested one in my own AirTag without any issues. The Energizer 2032 also works with AirTags, so both are solid choices for that purpose. Just make sure you remove the plastic tab before installing.
Is Energizer worth more than Amazon Basics for coin cell batteries?
It depends on what you value. The Energizer 6-pack gives you two extra batteries over the Amazon Basics 4-pack, plus child safety features like a bitter coating and Color Alert technology. But the Amazon Basics batteries have a higher 225mAh capacity per cell and are the #1 best seller in 3V batteries on Amazon. For most everyday uses, I’d say Amazon Basics offers better value per battery, but Energizer wins for safety-conscious buyers.
Which battery works better in extreme temperatures?
Energizer clearly wins this one. They’re rated to work in temperatures from -22°F to 140°F, which makes them ideal for car key fobs that sit in freezing winter weather or hot summer dashboards. Amazon Basics doesn’t list a specific temperature range in their specs, so I wouldn’t trust them in extreme conditions the same way.
Do both batteries work in key fobs and TV remotes?
Yes, both the Amazon Basics and Energizer CR2032 batteries are designed for exactly these devices. I tested both in a key fob and a TV remote, and they worked perfectly. The Amazon Basics are engraved with the battery model for quick identification, which I found handy when digging through my junk drawer. Either will get the job done for standard household electronics.
My Final Verdict
After testing both packs, my clear winner is the Amazon Basics CR2032 3V Lithium Coin Cell Batteries. With a 225mAh capacity per cell — the highest of the two — and the #1 best seller ranking in 3V batteries from over 184,000 ratings, they deliver the best overall value and performance for everyday devices. The Energizer 2032 6-pack is a solid runner-up if you need more batteries in the box or want the extra child safety features like the bitter coating and Color Alert technology.
If you’re still on the fence, ask yourself this: do you need maximum battery life per cell or do you need child safety coatings and two extra batteries? For most people swapping out remote and key fob batteries, the Amazon Basics pack with its higher capacity is the smarter buy.
