Questions about this item

What does the 220mAh rating mean for a device like a key fob or glucose monitor?

The 220mAh capacity indicates how much charge the cell holds; in low-drain devices such as key fobs or glucose monitors it typically provides months to years of service before voltage drops below the useful level.

Does the CR2032 designation guarantee it will fit every holder labelled CR2032?

Yes — CR2032 is an IEC size code that fixes the diameter at 20.0mm and height at 3.2mm, so any compliant holder will accept this cell.

What physical space is needed to mount these cells in a device?

Each cell measures 20.0mm in diameter and 3.2mm in height; the battery compartment must accommodate those exact dimensions for proper contact and closure.
