Frequently asked questions
Can I use other coin cells such as CR2025 or CR2016?
This holder is designed for the CR2032. Other coin-cell sizes differ in diameter and thickness, so check the dimensions and contact fit before using them.
How is it installed?
It is a surface-mount part, so the pads are soldered to the PCB, typically by reflow or with a fine-tip iron. Avoid overheating the plastic body during soldering.
