Since it is necessary to disconnect the battery when leaving the vehicle unused for a few days, especially if one has the immobilizer (which I did not order or want, but the car mysteriously arrived with it), I would like to be able to disconnect the battery more quickly. The system on my 1932 Austin 7 (no, I did not buy it new) was far better.
I've just fitted a Battery Brain (type III) with a remote control to disconnect/connect the battery. It seems to work well.
