Hi All, I need a good quality replacement battery for my laptop. The laptop is an HP Envy Notebook 15-as050na. The battery part number is VS03XL. iFixit does not seem to stock this part. I have previously bought replacement laptop batteries both locally and online, and the experience was not good. Google finds various suitable batteries ranging from £26.95 to £69.99, but can anybody here help me identify a reputable supplier? Thanks.
