As I am sure you know, that would depend upon (a) the length of time between starts, (b) how large the parasitic drain is, and (c) the effective capacity of a three and a half year-old battery.

My understanding is that for the E70, the acceptable parasitic drain is 40 milliamps after 60-70 minutes with TCU (30 minutes without TCU)

Depending upon what is not going to sleep, the excessive parasitic current could easily be such that it starts and is "made-up" if driven every day, but if left 3-4 days, would drain the battery.
