So quick question, when you pull the boat out of the water or on the lift after each outing do you do anything with the battery switch?
More often than not I leave it on 1+2 setting, however, I have noticed I have a parasitic draw somewhere and after about 2 weeks it will drain the batteries. That said, I usually have my on board charger plugged in as well. I have been getting in the habit of turning the Perko switch to off if I know I'm not going to plug the charger in for a while.
I was told with the newer boats to never use 1+2 setting. It was suggested to use 1 on a trip, then 2 on the next and continue to switch per trip. I realize it's a bit different for you guys with a lift, but I think the same rule could apply. Leave it on 1 and then change to 2 when you jump in the boat for the next outing.
I turn the switch to off when I pull the boat out of the water.
I do the same thing as moombahghrider. I alternate between 1 & 2 day by day. I turn it off at the end of the day then switch to the other battery the next day then off again when I leave it for the week. I just don't want to arrive at a boat with no battery power left.
I turn mine off too as I have also noticed a parasitic draw somewhere - which I believe is from the screen as it looks like it stays on , albeit extremely faintly.

I would definitely recommend that you do not leave it on 1+2 for extended periods. No two batteries are identical, leaving them connected together will cause a parasitic draw from one to the other. This may be minor but could be significant enough to be an issue over the long term. This becomes critical when a battery reaches the end of its life (typically 3-5 years). The dying battery will rather quickly drain the good one and leave you without enough battery to start. (The best case scenario is using two identical batteries of the exact same age. This is also why all electronic devices instruct you not to mix batteries types or old/new). Before I installed an ACR, I would always switch to 1+2 for the day of use and then to off at the end. (1+2 is good during use so that both batteries can charge).
I leave mine on so I don't have to reset the head unit from "demo" mode every week. When I charge (rarely) I open the #1 battery case and charge it overnight, then switch to 1 & 2 and charge overnight again, then flip back to #1.
I turn mine off after every outing and run it on 2 while
I'm out reserving 1 for a back up. I guess I should run it on 1 today to make sure it will start the boat

Fairly certain that the alt will charge both batteries as needed no matter if the switch is on 1, 2 or both. I always switch mine to off and about once a week or so plug in my onboard charger for maintenance. As for which battery to run, no idea, don't have any set pattern, just however I feel like flipping the switch.
I switch them both off every time I put it in the lift when done. When going out, I run it from 1 + 2 until I anchor to hang out, then I switch to one or the other while anchored and running the radio etc. to keep my house and starter batteries isolated. When done hanging out, I switch back to 1 + 2 so I can charge them both up before putting back up in the lift.
From what I've read, having it on 1 + 2 charges both equally from the alternator when the engine is running, and the entire point is to isolate a house battery and starting battery in periods of running solely off of a battery for a long time right?
Maybe that is all wrong, and I'm admittedly still a bit new at this, but has worked well for me thus far.
