I have a 2007 Range Rover SC which has served me well thus far. However, found the car would not start and charged the battery. It started but leaving it overnight, found that the battery was too weak to start the car - switching the ignition on there were no lights and gearlever did not want to move from park.

I put the battery charger on, this time leaving the battery terminals on, and it seems that there is a drain somewhere as the battery doesn’t seem to be taking the charge. Also, when I closed the driver and front passenger windows, it went up very slowly and at some point even stopped. I then had to close the windows one by one- this with the battery charger still connected.

Will appreciate advise on what could cause such a significant draw

I would have your battery tested.
