Hi,

The battery is type CR 2032  (3V) which you can get in any electronics store. 

It is not the easiest PC to replace the battery (RTC battery) as you need to remove the system board to get to it. You can see the steps on page 78 of service manual:

You can also take a look at these HP videos (click on Real-Time Clock Battery in list on left) which can help:
