DL2032 vs. CR2032 vs. BR2032: A coin batteries comparison

Small devices like remote controls, watches, and calculators might seem insignificant to the eye, but they play a huge role in your everyday life. So naturally, their maintenance is essential to ensure your day goes smoothly. 

Apart from ensuring the hardware is clean and proper, replacing batteries on time is also crucial for maintaining these gadgets. And with so many options on the shelves, it can get hard to decide which one would be best for your device. 

Most people are confused between DL2032, CR2032, and BR2032 batteries. If you are too, the following guide will be beneficial for you. 

Overview

People who don’t have knowledge and experience regarding batteries often find it hard to differentiate between these three products. To them, they might seem the same. However, there are significant differences between each of them. Knowing these differences can help you decide which one will be best suitable for you: 

CR2032 vs. DL2032

The most significant difference between the CR2032 and DL2032 batteries is their manufacturing companies. Apart from that, they are pretty much the same. Both have dimensions of 3.2 mm thickness and 20 mm diameter. Both offer 3 volts and are made from lithium manganese dioxide. In fact, their operating temperatures are also the same: -22°F to 185°F. They are also pretty similar in terms of prices. So, if you want to use one instead of the other, they will work fine. 

The only difference between DL2032 and CR2032 is that the former is manufactured by Duracell, while the latter has multiple manufacturers (CR is a generic IEC prefix). Plus, DL2032 has a capacity of 240 mAh while CR2032 supports 220 mAh. This difference in power might be insignificant to some people. However, it means that Duracell will last significantly longer than CR2032, which will have to be replaced sooner. 

CR2032 vs. BR2032

People usually get confused between these two batteries because they are sized pretty similarly. Both C42032 and BR2032 have 3.2 mm thickness and 20 mm diameter, so their physical appearance is the same. Some other similarities include a similar price range and voltage. CR2032 offers 3 volts, while B42032 supports 2.8 volts to 3 volts. Whether you consider this a similarity or a difference is entirely based on your perspective. So, you see, most people view CR2032 and BR2032 as pretty much the same. However, their construction is different, as the former is slightly weaker than the latter; BR2032 is more robust.

Along with this difference, there are some other reasons why it is not recommended that you interchange these two types of batteries. First, they have different capacities: the former offers 220 mAh while the latter comes with 180 to 190 mAh. Second, CR2032 has a lithium manganese dioxide positive electrode. On the other hand, BR2032 hosts a lithium carbon monofluoride positive electrode. Lastly, the former has an operating temperature of -4 degrees Fahrenheit to + 158 degrees Fahrenheit, whereas the latter works best at -22 degrees Fahrenheit to + 185 degrees Fahrenheit. 

BR2032 maintains a constant voltage for an extended period before degrading. However, once the degradation process starts, it proceeds very fast. In contrast, CR2032 batteries have a much more gradual degradation of voltage. For this reason, the latter is deemed ideal for devices that require more current to operate. Such gadgets include remote devices, key fobs, etcetera. On the other hand, BR2032 batteries work better for devices that demand a constant voltage over elongated periods. These would include memory backup applications and watches, etc. 

FAQ

Apart from the prominent differences between these batteries, there are some other frequently asked questions. The most popular ones are the following: 

1. Can I use a DL2032 battery instead of a CR2032 battery?

If you want to replace an old discharged DL2032 battery with a new CR2032 battery, or vice versa, you can. The two have the exact specifications, dimensions, and performances, meaning that you can use them interchangeably without any harm. Remember: the only difference between them is that they have different manufacturers. So, if you are a loyal, satisfied customer of Duracell, and you don’t want to take a chance with another company, you might want to stick to DL2032. 

2. Why does a CR2032 battery work and a DL2032 battery doesn’t?

As mentioned above, you can easily use the two batteries to replace each other without noticing any significant differences in performance. However, sometimes, it doesn’t seem to work. And in scenarios like such, there are explanations as to why it’s not working: 

  • You have placed the batteries incorrectly. 
  • There is something wrong with the terminals; they might be dirty, flawed, malfunctioning, or broken. 
  • You are using a dead or malfunctioning battery. 

So, if, at times, the DL2032 battery is not working as a replacement for the CR2032, it doesn’t mean you can’t use them interchangeably. It means there is something wrong with the batteries you are using or how you are using them. Take a step back; figure out what you are doing wrong. 

3. Are BR2032 and CR2032 batteries interchangeable?

Because of the significant differences mentioned earlier, replacing one of these with the other is never a good idea. Even though they have similar sizes, they are not meant to be used on the same devices or for similar purposes. A Cr2032 battery is ideal for appliances you use periodically, while BR2032 is more suitable for devices demanding constant voltage.

However, you should not be scared of replacing these with each other, nor is there a hazardous disadvantage of doing so. If you are in a tough spot where a suitable battery replacement is unavailable, you can temporarily interchange them. Of course, you must make sure there is a temporary hack. It’s not a permanent solution, nor should you do it very frequently. 

Final Thoughts

Understanding all your options makes it easier for you to make the best decision and choose the product that fits your requirements. Ensuring that you get suitable batteries for your devices and gadgets is as crucial as getting the right engine for your vehicle and the right shampoo for your hair. Because simply replacing a product is not enough, choosing the right one is just as important.
