Questions about this item

How do I install the CR2450 coin cell and which orientation mistake should I avoid?

Slide the 24.5 mm diameter cell into the holder with the marked positive side facing the contact indicated by the device; reversing the 3 V lithium cell will prevent the glucometer, calculator or car remote from powering on.

What replacement will the CR2450 need after its service life?

The 620 mAh lithium coin cell is a primary battery, so when the voltage drops below the level required by your medical or security device you simply replace it with another CR2450 or DL2450 equivalent.

What limit appears first when the CR2450 powers a device continuously?

The 620 mAh capacity determines runtime; under sustained drain the cell will reach its end-of-life voltage before the 10-year storage guarantee becomes relevant.
