After a couple of weeks received one laptop battery of the two batteries I ordered. (Missing battery was refunded. Unfortunately the rather expensive new Li ion (??) battery had a life measured in minutes and has been completely rubbish. The old laptop battery it was supposed to be replacing lasted longer !! I suspect it is a fake Li ion battery and there has been no reply to my e-mails. Don't trust there 2 year guarentee. It's worthless.
