Hi Jag11300,
Welcome to Sony Community!
We're sorry to hear about what happened to your battery. We can only replace a battery if it's still in warranty, otherwise you have to purchase the replacement.
You may refer to this link for further assistance, https://sony.encompass.com/model/SONSVT15112CXS/_/_/Sony/SVT15112CXS/Vaio_T_Series_15_Ultrabook.
Regards,
