I had my garage instal the eyelet lead and connector which came with my CTEK battery charger/maintainer on the battery + & - leads so that all I have to do is lift the bonnet, unclip the CTEK connector extension lead before driving the car, and the reverse when I park up in the garage. The connector is positioned above the battery towards the front firewall and has a rubber waterproof / dust cover.

Takes 30 seconds before driving, and a whole minute when plugging back in, in the garage.
