Questions about this item

How much current can the 620 mAh CR2450 supply during continuous high-drain use?

The cell is rated for high-drain applications and delivers its full 620 mAh capacity at the 3 V nominal voltage.

What device or holder is needed to connect the 2450 coin cell to my equipment?

A standard CR2450 battery holder or spring-contact compartment with 0.961 in diameter and 0.188 in depth accepts the cell directly.

Will the 3 V lithium chemistry work in older gear designed for 5029LC or DL2450 alkaline equivalents?

Yes — the ECR2450BP cross-references 5029LC and DL2450, so it fits the same holders and provides the same 3 V output.
