Google says:  capacity i / operate tempature is difference


TLDR

Br- -30C to 80C 165ma
Cr- -30C to 60C 225ma

To get operational at higher temp you give up capacity

Articles cited:

*BR2325's operating temperature is -30°C~80°C, while CR2032 is -30°C~60°C*.
The voltage of BR2325 and CR2032 are all 3V. The capacity of BR2325 and
CR2032 are not the same. The capacity of BR2325 is 165mAh, while the CR2032
is 225mAh.




CR type batteries are slightly less robust than the BR type when exposed to
temperatures at the high end of the operating temperature range and can
experience a rapid increase in self-discharge at the high end of its
temperature rating.
