CR1620 vs CR1632: What’s the Difference and Are They Interchangeable?
CR1620 vs CR1632: What’s the Difference and Are They Interchangeable? CR1620 and CR1632 batteries share the same chemistry, 3V nominal voltage and 16 mm diameter. The important difference is thickness: CR1620 is 2.0 mm thick, while CR1632 is 3.2 mm thick. That 1.2 mm gap affects capacity...Read more -
CR2016 vs CR2025: Size, Capacity, Battery Life and Compatibility
CR2016 vs CR2025: Size, Capacity, Battery Life and Compatibility CR2016 and CR2025 batteries look almost identical and both deliver a nominal 3 volts, but the 0.9 mm difference in thickness changes their capacity, runtime and physical fit. Choosing by diameter or voltage alone can lead to a lo...Read more -
CR927 vs CR1220: Best Coin Cell for Compact Devices
CR927 vs CR1220: Best Coin Cell for Compact Devices CR927 and CR1220 are small, non-rechargeable 3V lithium coin cells used in space-constrained electronics. They share similar chemistry and voltage, but their physical proportions are very different. CR927 has the smaller PCB footprint but is ...Read more -
CR2032 With Tabs vs Holder: Best Choice for OEM PCBs
CR2032 With Tabs vs Holder: Best Choice for OEM PCBs OEM engineers integrating a CR2032 battery into a printed circuit board typically choose between two approaches: a cell with factory-welded solder tabs or a replaceable CR2032 installed in a PCB battery holder. Both options can provide relia...Read more -
