CR2450 battery equivalent

CR2450 is a lithium manganese dioxide coin cell, 24.50 mm across and 5.00 mm tall, rated 3.0 V and 620 mAh. Energizer’s datasheet also prints the ANSI / NEDA designation 5029LC next to the IEC name.

Two makers, one answer

Energizer’s datasheet and Panasonic’s catalogue give the same figure for all five fields below, so there is no disagreement block on this page. The capacity is each maker’s own rating: Energizer rates it to 2.0 V at 7.5 kΩ, Panasonic at standard drain down to 2.0 V, and the number is the same.

Same name, other number?

5029LC is not a second cell. On Energizer’s sheet it is the ANSI / NEDA name for the CR2450, printed on the same line as the IEC name (the exact line is quoted in the codes list further down).

DL2450 is also searched for, but it is not printed on any maker sheet or cross-reference page this site cites, and we hold no Duracell or Renata CR2450 sheet, so we don’t list it.

Not a CR2032

The CR2450 and the CR2032 are both 3 V lithium cells, but they are different sizes on the datasheets, so the datasheets give no basis for swapping one for the other:
