That sounds like a car battery charger.

Thanks (and to the others who said the same).

I don't have any instructions: should I just attach the clamps and
switch on?

yes

Do I need to disconnect the car's own connecting leads

no

And how can I tell when the battery is sufficiently charged?

when the terminal voltage is over 13V


Many thanks.
