I am trying to find a replacement battery for a Librem 15 laptop, I know the model number is U753-TS44-111 but can't find it anywhere :(

The Purism site page for it https://shop.puri.sm/shop/librem-15-battery/ says it does not ship outside the USA, so seems like I am locked out of options...

Has anyone had similar issues before? How did you solve it?
