Thanks Richard and Gavin for the comments.
I haven't replaced the 9V in ages so that's no doubt the problem.

I don't necessarily run the engine for more than half an hour per day so
I'd better not go with that approach!

Re: RAM backup voltage, if that needs to be at least +3.5V, how does it
work with a 3V lithium or AAs? Or does it just work despite being out of
spec?
