CR1620 Battery Equivalent
Given below are some batteries that can be replaced with CR1620.
Here, it is evident that only the alphabets are different. The last four numerals are the same. Hence all these equivalents are replaceable with CR1632 but they differ in performance.
Note: The other chemistries may not offer the same features as the lithium-manganese dioxide chemistry. So it is necessary to verify the power requirements of the device before using an equivalent in the place of CR1632.
