I do usually use short cycles, but I tried a full discharge a few
times in the hope that it would help recalibrate.

I suspected as much. I think this one still has a fair bit of life
left in it, but I'll probably get one off ebay in the not-too-distant
future. Unless, that is, anyone knows of somewhere else in the UK to
get batteries at a reasonable price?

Thanks for your help,
