[W126 Coupe] Battery disconnect

[RONNY GEENEN]

GlacierI have a Jaguar XJ6 and a 300SD that my wife and I seldom drive. They are both parked in a garage. Of course after a while the batteries will run empty.
I tried to find a battery disconnect that RV owners are using, but most of those items do not fit, because of not enough available space.
I do not want to disconnect the battery cable or take the battery out. That is to much work. Any brand or model that will do the job?
I appreciate your help.
