EDIT: The title is incorrect but I can't change it. The model is Early 2021 not early 2015

I got my Blade 15 from the States but now I'm in the UK and am in need of a replacement battery due to swelling. I contacted US support and they can't ship me one being out of the country. At the moment my laptop is essentially a desktop having to be plugged in to be used as I have already removed the battery as it was preventing the touch pad from functioning correctly (stop gluing the batteries down please it benefits no one). 

Can I buy/get one from Razer UK? No where I look can I find a genuine replacement. Not offering battery replacements seems wrong to me.
