Anyone see any issue with leaving the on-board charger plugged in all of the time? I seem to have a small parasitic draw that has been killing my batteries. I almost always turn the switch to the off position but it still seems like if it is more than a couple weeks before I use the boat again I will come back to weak batteries.

I think the easy answer is just to make plugging in the charger part of my routine every time I cover the boat but I just want to make sure there are no ill effects of leaving it plugged in all of the time. For reference my boat is a 2015 with the stock dual battery setup and on board charger.
