Why does the idea appeal to you?

It appeals as it is easier to plug something into an exposed socket than to
keep lifting the bonnet.
It's the cold mornings that cause the starting troubles. Both battery and
charging have been tested and are ok. There may of course be a permanent
drain elsewhere.

Many years ago, I put a cigarette lighter plug on my battery charger
so I could just plug it into the cigarette lighter socket, and leave
it sitting in the dry car (in the footwell) whilst it was charging.
That charger was only 4A max.

However, I don't recall ever needing to charge my own car batteries - it
was always someone else's.
