The Best CR2032 Battery


Duracell CR2032 Batteries

Current Check: Best CR2032 Batteries – Gear Hungry (4)

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.

Duracell deploys its proprietary Duralock Power Reserve Technology to make its batteries last in storage (and to give users the confidence to buy in bulk.) The tech, first released in 2012, consists of claimed ingredient purity, a unique separator to protect the anode and cathode, and a highly corrosion-resistant exterior.

Finally, Duracell coats each lithium CR2032 battery with something that tastes bitter, to deter children. One reviewer went so far as to taste it — that individual was disappointed, unfortunately, because the initial shock of tonguing the battery precluded the bitter taste. Despite the results, we have to admire their commitment to testing.

Duracell’s CR2032 batteries promise to keep well on the shelf and perform solidly when installed. Though a few quality control issues seem to exist, they’re bound to pop up when you sell this many batteries. Duracell’s CR2032s are among the internet’s most popular.

Sony CR2032 Batteries 20-Pack

Current Check: Best CR2032 Batteries – Gear Hungry (5)

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.

The situation generates an interesting roulette effect in terms of the remaining shelf life of Sony CR2032’s purchased online. The “use by” date is printed on the back of the package; it seems the best you can hope for is a high number.

However, among a multitude of Amazon reviewers, results seem consistent. Scouring the available information, it looks like a few batteries have occasionally aged out by the time they get to the user. However, the same thing appears true for many confirmed new packs of CR2032’s.

Apples to apples? We don’t know. Either way, at the time of this writing, you couldn’t beat the deal on Sony’s remaining CR2032 batteries. Are you sold and only wish you could get more in one fell swoop? Check out the bulk 500 pack, of which 2 remain on Amazon.

LiCB CR2032 Batteries

Current Check: Best CR2032 Batteries – Gear Hungry (6)

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.

As with any unknown brand, it’s reasonable to expect less consistent quality and worse customer service. Big brands have more to protect; some small electronics manufacturers just don’t care. Although LiCB makes no promises when it comes to warranty or troubleshooting, it does seem to deliver a reasonably reliable product.

Put it like this: if you’re shopping for a CR2032 battery to run a critical item like a medical device, you’d do best to stick with the experts. But if all you need is to power your tea lights, the LiCBs may be worth a shot.

Nightkonic CR2023 Batteries

Current Check: Best CR2032 Batteries – Gear Hungry (7)

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.

The brand differentiates the product with quantity at the price point. As of this writing, you couldn’t get more relatively reliable CR2032 batteries for cheaper unless you perhaps went through illicit channels. Even then, I’m not convinced — if you made your product much cheaper than the Nightkonics, the crime wouldn’t be worth the payoff.

At any rate, the vast majority of all negative comments are typical: short or no life in some pieces on delivery. Complaints are similarly dispersed as more expensive competitors. For your money, Nightkonic might be the way to go if you want a lot of extra ammo.

XLUX Rechargeable LIR2023 Set CR2032 Batteries

Current Check: Best CR2032 Batteries – Gear Hungry (8)

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.

Instead of churning through CR2032 batteries (dropping the dead ones off at an approved recycling center), try a rechargeable LIR2032. Be aware, there are a couple critical performance differences between the two.

First, rechargeable LIR2032s sometimes achieve higher voltage than CR2032s. That means they may not be compatible with every device. LIR2032s use higher voltage because their capacity is not as high as CR2032s. That being said, they won’t last as long. Users should calibrate their expectations accordingly; the trade-off is a re-usable, lower performing item versus a single-use, potentially highly performing item.

The charger indicates battery status with LED lights. Some users are skeptical about the charger. It’s important to note it’s possible to misuse the charger: putting regular CR2032s in it can cause a short circuit.

All things being equal, XLUX’s LIR2032 rechargeable battery set promises better sustainability than single-use CR2032s. There is a difference in performance, but it could definitely save heavy coin battery users money over the long haul.

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 resourceto 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 batteriesare 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.

Are all 2032 coin batteries the same? ›

This is the case when it comes to CR batteries like the CR2032 and DL2032. The main difference between CR and DL batteries is just the maker. CR is basically a generic designation just like AA and AAA. It is used by almost all battery makers.

What battery is better CR2032 or 2025? ›

The CR2025 is slightly better suited for use in products that have less available mounting space than those that would use a CR2032. On the other hand, the lower capacity (mAh) of the CR2025 will give a slighlty shorter service life than a CR2032 when used in similar applications.

What voltage is too low for a CR2032 battery? ›

Of course, if a circuit can't function below 2.0 or 2.4 volts, the added drain makes an even starker reduction in useable battery capacity. If the CR2032 battery must contend with a pattern of pulsed demand for current, that, too will cause a derating of the optimal 225 mAh figure.

Can CR2032 batteries be thrown away? ›

Lithium-ion batteries and devices containing these batteries should NOT go in household garbage or recycling bins. Lithium-ion batteries SHOULD be taken to separate recycling or household hazardous waste collection points .

Which battery is no 1? ›

In addition, it also provides home UPS systems, integrated power backup systems, solar solutions, e-rickshaw vehicles and demineralised water. Exide manufactures batteries with a capacity ranging from 2.5Ah to 20,600Ah.

Which battery is best quality? ›

Lithium, an exceptionally light metal, gives lithium batteries the highest energy density of any battery cell. Thus, they can store more energy than alkaline batteries or any single-use battery of a comparable size. And they are superb performers in extreme temperatures, both hot and cold.

What is the leading battery brand? ›

The top three battery makers (CATL, BYD, LG) collectively account for two-thirds (66%) of total battery deployment. Once a leader in the EV battery business, Panasonic now holds the fourth position with an 8% market share, down from 9% last year.

Which battery brand lasts the longest? ›

In the end my hypothesis was correct and the Energizer outlasted the other two types tested. It ran for 309 hours, where Duracell ran for 247 hours, and Panasonic ran for 176 hours. Based on my findings I would strongly recommend using Energizer batteries.

Which battery has the longest lifespan? ›

Like lead-acid batteries, for example. Lithium batteries currently have the longest lifespan of all available deep-cycle batteries. Many can last between 3,000 and 5,000 partial cycles. For comparison, lead-acid batteries typically give 500 -1,000 partial cycles.

What is the alternative to Duracell 2032 battery? ›

The CR2025 battery is an extremely common lithium coin cell battery and is used in similar amounts and in similar applications as the CR2032. The CR2025 is slightly better suited for use in products that have less available mounting space than those that would use a CR2032.

Are Maxell batteries good? ›

I'm happy with the power and function of these batteries and the box is great to store them in. They have as much power as most standard batteries, except perhaps Energizers, and they go about as long. I like them better than Ray-O-Vacs personally, and they are much better than most generic batteries.
