I have a car that is only used intermittently.
I have fitted a quick disconnect to the battery to stop discharge and I either run the car once a week or give it a quick charge.

My engine management unit will lose the engine tuning if I do that, and
spends first 5 miles relearning it. It's noticably rough for first half
mile or so. I can't imagine it's particularly good for the engine to do
this repeatedly.
