I was looking for one of these to replace one in an old iMac. They normally retail for around £6 and I had bought one on EBay for £2.25. But I happened to be in Maplin today and saw one for 65p reduced in the closing down sale to 23p! I think these are a discontinued range because they sell and almost identical cell for £6.50 and this 23p one does not appear on the website. At this price I’d have bought every one they have, but sadly this was the all alone. If you deal with older computers it would be well worth checking your local Maplin and stocking up.
