During lockdown, in common with many people I assume, I put our cars on a trickle charger as they were not being used as much as normal. So far so good. But! In my 2013 CLS 350d SB the stop/start function stopped working. The same was true of my BMW M140i when the battery was low but charging the battery in that cured the problem.
I understand in the CLS it is the AUX battery in the boot that is crucial for the stop/start. Is there anything to stop me putting the trickle charger on that battery?
