I've SORNed my car as I'm not going to be able to drive it for a couple

to do on the various electronics.

It's many moons since I last charged a car battery and at that time I
just clamped the charger leads on and let it get on with it.

Put the charger on a plug in timer set for say a half/quarter hour per day.
