The Best CR2032 Battery
Duracell says it makes its CR2032 batteries with high-purity lithium for long life. Duralock Power Reserve Technology gives the batteries a 10-year guarantee in storage. And they even have a bitter-tasting coating to help keep children from swallowing them.
High-purity lithium would ostensibly be preferable to a contaminated variant. We can’t corroborate whether Duracell’s lithium is particularly special or not. But the CR2032s do enjoy a reputation for being long-lasting, especially in smaller devices. Most verified buyer write-ups use Duracell CR2032’s for car key fobs. In this capacity, they seem satisfactory.

Sony serves up a 20-pack of pedestrian CR2032 batteries at a bargain price. Sony makes no claims that the batteries are particularly special; the deal leads with quantity. As well, the manufacturer has since discontinued the item, leading to a unique availability situation. The 220 mAh capacity batteries come in 4 blister packs of 5 cells each. They are classic lithium manganese dioxide batteries.
Beyond that, there’s not much to tell. Notably, this appears to be some kind of wholesale or liquidation item from Sony. As of this writing, the brand no longer listed CR2032 batteries of any kind on its website. That means that packages of differently aged batteries are indiscriminately available.

LiCB may not be a household brand name, but it makes a case for respectability with its CR2032 batteries. The cells are CE and RoHS certified for product safety, have a 3-year shelf life, and come in 2 packs of 5. The batteries are very popular and overall, highly regarded.
The only quality complaints that exist are the typical ones: instances of batteries dead on arrival, or short life. But more or less, the complaints are as sparse as they are with most of the bigger brands.

Nightkonic leverages the quantity principle to deliver its CR2023 batteries. Interestingly, it doesn’t seem to sacrifice quality any more than most of its pricier competitors.
The Nightkonics are nothing special. Not nickel-coated, no special technology; just the thing itself. A 230 mAh capacity is the only semi-noteworthy spec.

XLUX’s rechargeable lithium coin battery set is a good place to start for those interested in reducing their CR2032 waste profile. The wall plug charger comes with 4 LIR2032 batteries (LIR = lithium ion, rechargeable). It’s compatible with both European and United States plug styles.
Increasingly, we’re paying the price for reducing our carbon footprint in increasing lithium extraction. The process is highly water-intensive, and lithium is a non-renewable resource.

Why Trust Us
Testing watches, electronics, and general home gear gives us a consistent need for CR2032 batteries. As we’ve gone about finding and reviewing the best gear on the market, some of the best supporting tech has come to the surface. We’ve tested some of the longest lasting CR2032 batteries, as well as some of the cheaper entries.
Who This is For
Anyone who uses CR2032 batteries and wants to find the ones that work best for them. Whether you want long CR2032 battery lifetime for your watch, or a rechargeable entry for your home lighting, it’s here.
How We Picked
2 qualities really stand out in CR2032 batteries: reliability and lifetime. As one of our experts succinctly said, “I just want a [expletive] battery that I can forget about for a year.” Wouldn’t that be nice? We also looked at reliability; it doesn’t matter how long a battery’s supposed to last if it burns out before then.
How We Tested
We’ve tested various lithium CR2032 batteries during the everyday process of reviewing gear. Our experience typically involves watches; we’ve performed most of our testing involving remotes, LED mood lighting, etc. off the clock. In our experience, we've never encountered an alarming situation like a leak, explosion, or early burnout.
Features to Look for in CR2032 Batteries
Capacity and Voltage — As a general rule, CR2032 battery voltage is 3V. It can vary by half a volt or so and might read differently depending on the battery’s age and use.
Capacity is measured in milliampere-hours (mAh). Many CR2032 batteries have between 190 and 225 mAh capacities. What does this mean? Essentially, a CR2032 with a 200 mAh capacity can deliver 200 milliamps of current for 1 hour. Or 400 for half an hour. Or 100 for 2 hours. And so on. Get the picture?
Here’s a handy resource to help demystify mAh.
Temperature Tolerance Levels — CR2032 batteries have a temperature tolerance from anywhere between -22- and 185-degrees Fahrenheit. Not every CR2032 battery will tolerate such extremes, but many can handle a very wide range of temperature.
We’ll list temperature tolerance in each product review.
Shelf Life — Passive discharge limits shelf life in batteries. CR2032 batteries generally discharge at about 1% per year. Under some conditions, the rate may be a little higher.
Regardless, shelf life is the amount of time it takes for the battery to lose 10% of its initial capacity.
Leak-Proof Lithium-Ion Batteries — It’s very rare that fluids leak from a CR2032 battery, especially if it’s not damaged.
Many brands specify that their CR2032s are leak-proof. But unless it’s somehow punctured, it should never leak.
CR2032 Battery FAQ
Q: What is a CR2032 battery?
A: A CR2032 battery, often called a button cell battery, is a 3V cell often used in small electronics. Watches, small remote controls, wireless doorbells, calculators, etc. usually use lithium CR2032 batteries.
CR2032 battery dimensions are about 20mm x 3mm.
Q: Do CR2032 batteries contain more toxic chemicals than other batteries?
A: Not really. Every battery uses chemicals and compounds that are harmful to us and the environment.
The difference is that generally, we don’t consume or come in direct contact with what’s inside the battery and isn’t supposed to get out.
Lithium is harmful and environmentally costly but very widely used. The world’s growing problem with lithium batteries is well-documented. CR2032 batteries also use an array of other common battery materials like zinc and manganese dioxide.
Interestingly, hemp batteries are non-toxic and have outperformed lithium batteries in tests. Just sayin’.
Q: How do you dispose of CR2032 batteries properly?
A: Any lithium battery should be recycled at a battery/device drop-off location. To find one near you, go here. Lithium and other toxic battery chemicals leech out of punctured batteries in landfills, making their way into soils and waterways.
Q: How long should a CR2032 battery last?
A: This is a moving target. Many last around 2 years, and some manufacturers claim a CR2032 will last up to 10 years in their devices. Say your smoke alarm uses a CR2032, and so does your watch.
The smoke alarm almost never draws any power, but your watch operates constantly — and, depending on the features, sometimes draws additional current. Clearly, the battery in the smoke alarm will last longer.
