The battery of my laptop swelled

A year ago and a few months ago I bought a Razer Blade 15 Base Model which has a GTX1060 (Excellent laptop, I can't be happier with my purchase) poer I noticed that the touchpad area swells up a little bit, you can tell it's the battery and I'd like help buyingr the best spare part possible. (I don't know if they have service centers but I can't send it because I live in the Caribbean and all time sent an article to the USA).
