I spent some time yesterday re-calibrating the battery/laptop and now may be I do not need a new battery yet, it was showing 18% when I booted it up and lasted 20 min, and now after doing the re-cal (as in links above ) it is showing 45% and lasting 2 hrs

I've been buying them from eBay but only from seller in the UK and that are top rated. Find I can get one for around £20-30 which isn't too bad I don't think.
