Sony battery for DSC h50

Hi guys. I have DSC H50 which was released in 2008. I have not been using it for many years like maybe from the past 10 - 12 years. I am looking for an original sony battery but couldn't find it anywhere online or in stores. They are giving some 3rd party batteries and chargers. Not sure about the sony website as well, can't even see that model. How could I possibly get the original one? Not sure if I'm posting this in the right sector.
