I think the computer cell (originally, a battery was two or more cells,
but that distinction seems to have been lost years ago) is likely to be
a CR2032, not a 2025. The latter is thinner, but the same voltage (one
cell - somewhat over 3V when new), so if you can make it fit (e. g. with
a coin), it'll work - just not for as long as it has less capacity.

For anyone brought up on the confusing and apparently random names for
batteries - PP9, PP3, U2, HP14, baby, mignon, D, C, AA, AAA (yes, there
is F - though I've often wondered what happened to B and A!) - the CR
series are logically named: the 2032 (by far the commonest) is 20mm
diameter, 3.2mm thick; the others in the series are the 2025 and the
2016, and you can guess what their dimensions are. (I'm not sure about
the CR part stands for - maybe it means cell, round?)
