Razer Blade Stealth 13 Battery Expanding

My razer blade stealth 13 battery is faulty, and has been expanding (bubbles created)! I am not covered under the limited warranty anymore, but I believe this is a product defect, and not something my normal use is responsible for, and something that should be helped to be remedied by Razer support. Please see attached photo for what I'm referring to and thanks in advance for the help.
