IBM thinkpad 770E: which CMOS battery?

Dear all,

I've posted this in another group, but I am not sure which one is more
appropriate...

I have an old Thinkpad 770 E, where I need to replace the CMOS
battery, it won't boot otherwise.

Now I toke the battery off some long time ago, meant to go to the
shop....
AND LOST IT !!!!

I could not find anywhere in the imb web site or somewhere else about
the specs of this battery.

Can anyone tell me about it please?
Is it a 3 volts? or what else?
Which model?

I would really appreciate a lot any help.
thank you,
Mik

I don't have personal knowledge but vendors agree that it is a CR2025:

etc.
