Yeah - been there, got that T-shirt. Sadly, some idiot had left both batteries connected, so we ended up with no power at all. I won't make that mistake again.
Of course, the extent to which the battery drains depends on how hard the autohelm is working, so sea conditions, point of sail etc will affect the time taken to reduce the battery to an unusable level.....
