@albertemc2 there are no official replacement parts available for any Pixel. Looks like the battery is a Toshiba model. There is a company that is already shrouded in mystery, black helicopters and even more secretive than Apple. So it will be up to you to try and find one based on the actual battery. The Toshiba battery model is PA5280U-1BRS
