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

The capacity of a is measured in amp hours which is the amount of charge a can store. The amount of charge the can store is dependent on the mass of active material the contains.
CR2032 Battery
A typical has a capacity of 240 mAh. The will last for about 10 hours when using it with an average load of 24 mA.
CR2016 Battery
A typical has a capacity of 90 mAh. The will last for about 6 hours when using it with an average load of 15 mA.
Voltage
Simply put, the of a is the measure of the difference in electric potential between the negative and positive terminals.
CR2032
The typical is a .
CR2016
Thickness
The of the is the height of the . It is the difference in measurement between the top to the bottom of the . You can quickly get the of the CR-series batteries from the last two digits of the name in a tenth of a millimeter.
CR2032 Battery
The has a of 3.2 mm.
CR2016 Battery
The has a of 1.6 mm.
Rechargeable
CR2016 and CR2032
Can you use a with these ? Both the CR2032 and CR2016 are disposable batteries and therefore are not rechargeable.
They contain ions which, when recharged could spill.
You should not attempt to charge them.
Conclusion
In conclusion: Are CR2016 and CR2032 interchangeable? Devices that use a single usually cannot accept the thicker CR2032 because it will not fit into the . Conversely it may seem reasonable that your could get by using two stacked CR2016 replacing one CR2032. The dimension may work but the is not right. Stacking two CR2016s (which is not recommended) gives 6V (3V+3V) instead of 3V that a single CR2032 provides.
