Duracell Duralock CR2032 Lithium Batteries – Our Top Pick
The Duracell Duralock CR2032 Lithium Batteries are “the best 2032 battery” on the market because they have super high quality.
They are reliable products that never leak and can even be used in medical devices. They are the best 2032 battery for a key fob.
What is a CR2032 3V lithium coin battery?
The CR2032 battery is a lithium coin cell battery that is 20mm in diameter and 3.2mm thick.
It’s widely used in daily used applications like calculators, watches, and automobile keys, and medical devices such as implantable cardiac defibrillators, artificial cardiac pacemakers, and hearing aids.
Compared with alkaline batteries, lithium batteries are slightly more expensive but weigh less while having a higher capacity and wider temperature range. They have the best performance compared with all competitive products in their size and voltage range. This is why it is easy to understand the reasons for the CR2032 batteries replacing batteries, such as the 5004LC 2032.
What to look for when selecting a CR2032 battery?
If you are looking for a CR2032 battery, the first thing you should remember is that the numbers after the “CR” stand for its size (as mentioned above). Also, a CR2032 battery provides 3 volts to support your electric device; it shouldn’t be mixed up with the Renata 751 which provides only 2 volts.
We urge you to be careful as there are a lot of replicas and fakes on the market. Generally, if you find a CR2032 battery priced lower than one dollar, this battery may be substandard or fake. To find quality products, you should focus on famous brand products and pay more attention to the capacity and battery life.
Furthermore, if you want to buy more batteries as backup, you should check their manufacturing date. Keep in mind that a recently produced battery certainly has a longer shelf life. After all, batteries will erode and discharge after long periods of inactivity.

Frequently asked questions on the best CR2032 3v
What does CR mean on the 2032 battery?
The C in CR means that the battery uses lithium chemistry. The letter R means that the battery has a Round shape. Note that the first two numbers (20) let you know the diameter of the battery in millimeters. The last two numbers tell you the height, again in millimeters.
Are all 2032 batteries the same?
Yes, all 2032 batteries are the same in terms of dimensions. They are 20mm in diameter and exactly 3.2mm thick. That’s why they are referred to be 2032 (20 for the diameter, and 32 for 3.2 mm thickness).
Now, you’ll find that you can buy two main models. The first one is the CR2032 batteries and the second is the BR2032. The only difference between the two types is found in the material used to manufacture the electrodes. The BR2032 has a carbon monofluoride-positive electrode. The CR2032 has manganese dioxide material for the positive electrode.
How do you dispose of CR2032 batteries properly?
When it comes to disposing of lithium-ion batteries such as the CR2032, proper handling is essential for both safety and environmental reasons.
The best way to dispose of CR2032 batteries is by recycling them or taking them to a local hazardous waste facility. This ensures that they are disposed of properly and in accordance with local regulations.
If this option isn’t available, then you can also dispose of the battery at a designated drop-off point where it will be recycled or safely disposed of. Furthermore, it’s important not to throw these types of batteries in the trash or incinerate them as they may cause harm if mishandled or damaged during disposal. Worse, if these are dumped into landfills, their dangerous substance will find their way into soils and waterways.

What is the best brand of CR2032 batteries?
The ones we recommend are described above. In fact, I summarized only the best cr2032 battery brand. Duracell and Panasonic are very strong brands and both highly competitive in terms of prices and offers.
The quality is excellent for both CR2032 brands. The two companies offer the cr2032 longest-lasting battery. So you are safe in using these. And they are also the CR2032 battery best buy in terms of quality versus price.
How many years does a lithium CR2032 battery last?
A standard lithium battery is said to be very good if it lasts for about 3 to 5 years. However, CR2032 batteries can last much longer than that. In many cases, it can last for up to 10 years of use. Note that the longest-lasting cr2032 is the Duracell followed by Panasonic. These are also the best quality cr2032 batteries.
How can I safely and properly dispose of CR2032 batteries?
The most sensible thing to do to safely dispose of CR2032 and any type of battery is to drop them at a specialized recycling center. You can also find some disposal units at supermarkets. There are also collection points for used batteries around cities and these are documented on the web. Aim at not disposing of batteries in your home trash as they may end up buried and may harm the environment.
How do you know if a CR 2032 battery is good?
Here is the best 2032 battery test to determine if your battery has still some life within it. The easiest way is to use a multimeter. Set the multimeter to “DC Voltage” mode. Now ensure your red lead/probe is touching the (+) sign of the battery. Put the black probe on the negative side of the battery (-).
A CR2032 battery is a 3-volt battery. So if your battery is about 2.7 volts and above, then it is still good to use. Anything below that voltage and it is best to change the battery as it does not hold enough power to support your watch or other equipment. Et voila, your cr2032 best battery is either really good or ready to be replaced.
Can a CR2032 be recharged?
Well yes and no. The vast majority of CR2032 is not rechargeable. So do not try to recharge the ones that are non-rechargeable.
The reason why manufacturers do not make them rechargeable is that they are really cheap to buy. As such, they do not bother to develop a charger because the leaders in this space do not believe people will buy the chargers.
The manufacturers believe that it is more cost-effective to get a replacement and longer battery lifetimes than investing in developing a charger and its associated batteries.
However, other manufacturers are now challenging this on the basis of environmental impact. These manufacturers have developed chargers and batteries that go with them. We have provided one of the best chargers and rechargeable CR2032 batteries (see above).
Overall, only you can make that decision. You now know, and have a choice between single-use or rechargeable batteries.
Where to buy the best CR2032 battery lithium coin cells?
All major retail outlets like Walmart, and small corner street shops carry CR2032s batteries in store. You can also find these online via Amazon or other online e-commerce platforms.
In addition, many drugstores and electronics stores also stock them in their stores. Purchasing from these large retailers is generally more convenient since they offer either same-day pick-up or next-day delivery services depending on your location.
Note that you can find different packs of four, six, or eight. We believe buying a 4-pack is the best option as these are mostly reliable CR2032 batteries with a minimum of 3-year shelf life.
Do CR2032 batteries contain higher toxic chemicals than other batteries?
This is a difficult question and the answer is “it depends”. What we mean is that this depends on the manufacturer. Any battery will have some harmful chemicals and compounds. That’s the negative side of batteries and we cannot really do something about it. The only good thing we can do is to ensure that we dispose of them at the right locations with the right recycling companies to deal with them.
So, some companies will use more harmful chemicals than others to keep costs low. So the rule of thumb to use is to go for a branded battery product. Why? Because a brand works really hard to keep a good image. And as part of their image, they need to ensure that they work positively towards solving environmental issues such as the disposal of batteries.
Now, it is important that you do not consume or get into contact with the compounds and chemicals that make up a battery. So ensure these are not accessible to children.
Manufacturers are working towards non-toxic batteries. But these are still at an early stage.
