Secondly, we have Manganese dioxide lithium batteries, which are mostly used by consumer and commercial purposes, and they have the prefix CR and are referred to as a CR lithium battery. Firstly we have the Poly carbon mono-fluoride lithium batteries, which we use when extended reliability and safety are needed, and they have the prefix BR and are referred to as BR batteries. It may interest you to know that there are two commonly used types of lithium batteries. Nevertheless, substituting one of the cells with another may not work in some devices and is not recommended. They may both be coin-type batteries, but a closer look at the CR2032 vs CR2016shows that they are not interchangeable. You can find these two cell batteries in a wide variety of electronic devices like watches, calculators, glucose monitors and computers. The significant difference between these two batteries is their power capacities and sizes. The CR2032 and the CR2016 are coin-type batteries that look similar and provide the same voltage.
