You've done the customary simple test to make sure it is the battery

If it started the car on Saturday, but wouldn't on Tuesday, then I
agree that I would suspect the charging circuit rather than the battery.

Remember starting my car normally and driving to the shops. After shopping
and going to the cinema - say about 3 hours, battery totally flat. And it
was just the battery knackered.

I had a similar result with the battery that came with the brand new car.

After about 5 years, I started to get the result you got. But with a
different
effect where the battery would come good after waiting for a while.
Definitely
wasn’t the connection to the battery, removing and cleaning and replacing
the connection made no difference. Couldn't jumper start the car either.

Eventually it didn’t come good after waiting for a while, so got a mate
to come and pick me up and go and get a replacement battery. When
we got back, the car started fine, again. Replaced the battery anyway
once I had driven it home. Never had the problem again. He actually
took the faulty battery and used it on his solar panel for years.

The battery presumably had an internal crack in the connection
between the cells.

At one time a battery would usually give warning before failing. This one
didn't.

Bet it had the same fault as mine.
