Hi I am reposting this as the battery was missing from the photos. I have included any technical info for anyone who needs it.
As I said before it is only about 1 year old and has not been used very much. I accidentally ended up with an American hand held hoover (an Amazon fail on my part) so I had to buy a convertor as well.
