# CMOS Battery in MacBook Pro 2007

CMOS battery in my MacBook Pro (2007, pre-unibody) has died recently.

I am looking for a replacement, although all I could find so far was only used batteries off ebay.

It says following on the battery's shrink wrap:

CR2025/USTC
PW3+3V
7 8 21


Under the shrink wrap it says:

Panasonic
CR2025
3V
