Dyson v7 spares or repairs (Meadowhead S8)

Cordless Dyson - doesn't work!!
I have just replaced the battery with a brand new one from Amazon, but it still does the typical stopping and starting issue Dysons have, tried unblocking and cleaning filters etc but it still won't work. If you're handy and can be bothered, it's yours!
This was a good hoover before we got a cat and dog, it's not good for cleaning up pet hair.
