There are 2023,2032 and 2025 batteries. My blood test meter calls for 2023. Don't know if the others will work equally well even though they are the same diameter.

First two digits are the width of the cell in MM, last two digits are
the thickness in fractional MM

2023 = 20mm x 2.3 mm thick.

2032 = 20mm x 3.2 mm thick.

the voltages are the same in all, the thicker cells last longer and
provide more current if needed.

you should be able to use the 2032 cell if it isn't too thick to
close the cover.
