Yes this could be the case.  
It seems a PP400 powerpanel and the ordering code for a new cmos battery is:

See manual in following link:

for instructions of replacing this battery.

Hi there,

while this /could/ be a cmos battery, your post is lacking a lot of details, starting with the actual thing people are supposed to see on the picture. Please note that the information you actively give is the only one people can operate on.

It’s good on Corne’s part that he probably recognized it and was able to help but I advice for future posts to provide as much details as possible, not as few as possible.

Thanks and best regards  
Michael
