1. The car is used once or twice a week, mostly for short trips.

2. Nearly every time we use it, the battery is too dead to turn the
engine over and it needs to be charged. In fact it's so dead that even
trying will produce nothing but a click and drop the voltage across the
electrical system so low that it resets the clock.

3. After 20 minutes or so of charging, it'll start without difficulty
(it's only a 1.2l engine).

4. Alternatively, a quick push will do the trick.

5. If it has just recently been on a long drive (in the previous day or
so), or has been used once that day already, it will start without
problems, though.

6. More than once recently though I've stopped the car for a few moments
after driving several miles, and will find that it doesn't start and
needs a push to get going again.

7. It's getting worse.

8. The battery is fairly new.

Thanks for the many replies.

On the basis of advice, I disconnected the battery five days ago
(Sunday), charged it up, and left it disconnected. This morning
(Thursday) I reconnected it; the engine started immediately without
issue (and the same for multiple subsequent starts).

The battery reads about 12.3v while connected and the same disconnected.
At idle, it reads just about 14.3v.

I couldn't read anything between the battery earth and the chassis.

So it sounds to me that the battery is fine.

What do you suggest for the next step in the investigation?

Well you have remade the connections.

It should be fine now as the lost likely explanation was a bad connection.
