All my Morgans needed a battery conditioner on otherwise after approx 2 weeks they would have flat batteries, this was not a problem but I often wondered why as my tin tops can be left indefinitely and not drain the batteries.
I always used a conditioner whilst not in use, on the Aero I could flick a switch under the bonnet and isolate the battery which was easy except I had to reset the electric windows every time I did it.
