Makita 12 volt cordless drill - needs new batteries (Horsley GL6)

This has been great for me to use outside - but I'm finding that there sometimes isn't enough power for some of the jobs that I have to tackle. I went to the Repair Cafe on Sunday to check out the batteries, as they don't seem to be able to charge any more, and wanted to check whether it was battery charger or the batteries themselves that were the problem. Apparently it is the batteries.

On Ebay they are £10 for a single and only a little more for 2. I think I need to put my dosh towards a new more powerful drill. Does anyone want to take this 12 volt on?
