FAQs:

Can i use cr2032 instead of cr2030?

The thickness of R2032 is 3.2 mm while that of CR2030 is 3.0 mm. In addition, CR2032 usually has higher capacity than CR2030.

You can use CR2032 batteries instead of CR2030 batteries, as long as the added thickness does not cause device compatibility issues. However, it's a good idea to check your device's user manual or contact the manufacturer to make sure the substitution won't affect the performance or safety of your device.

will a cr2032 work for cr2016?

CR2032 and CR2016 batteries have the same diameter (20 mm) but different thicknesses; the CR2032 is 3.2 mm thick while the CR2016 is 1.6 mm thick. Therefore, due to the thickness difference, the CR2032 battery cannot be used in devices that require the CR2016, as its thickness may cause damage or incompatibility with the internal components of the device.
