This may not apply in all cases but I think with the electronics in the newer boats, it's not actually recommended to run in "1 + 2" mode unless it's an emergency....
Excerpt from the '17 Owner's Manual:
Skier’s Choice installs a 4-position battery switch on any boat equipped with dual batteries. It is recommended that both batteries
be fully charged between each use to insure they can deliver the electrical demands required for each outing. The purpose of our
recommendation is to utilize one primary battery for all operational needs, and have the other as a backup if the primary battery
discharges. This situation could occur if you run your accessories such as ballast or stereo for a long time, without running the
boat. The dual battery setup is designed to create a redundant system allowing the user to have a backup battery. The switch
must be in the “1” or “2” position to create the redundancy.
The 4 positions available on the battery switch are: Off / 1 / 2 / 1&2. These choices indicate which battery is being used to power
the boat and which battery is being charged by the engine’s alternator. We recommend using only position 1 or 2 while boating.
Battery switch position “1&2” is available but not recommended as power will be drawn from both batteries and the alternator
will have difficulties keeping both batteries charged simultaneously. It also creates a ground differentiation which in turn will
create issues with sensitive electrical components such as the Vision screen. The only time you may need Position 1 &
2 would be in an emergency situation where both batteries are low and need power from both to help start the engine.2017 Moomba Craz Surf Edition

This is essentially us. My bilge is wired direct to battery. If not, I'd leave it on 1 or 2 if it was in the water or exposed to rain.
If we are going to be anchored for a period of time I'll make sure I'm using the bank built for the stereo. 2 6v.
As to the poll question ... if you are leaving it on 1 and 2 when stored, you are not utilizing the purpose of the switch.Last edited by KG's Supra24; 08-16-2017 at 10:32 PM.

I turn them completely off after every outing and always charge them with my dual bank charger every time. That was the recommendation of both the stereo installer & battery manufacturer.
I usually run it on 2 which is my big stereo battery. If it for some reason drains out I can switch to 1 and still be able to start it.
Sometimes I run on 1 just to use the battery a little bit. When ever anchored or moored and listening to stereo it's on 2. I never have them on 1+2. I also never charge it with the switch on 1 or 2 always in the off position.
I've never had to reset my stereo settings or anything like that.

I guess I'm lazy. I have two Walmart Everstart Maxx group 29 batteries on bank 1. That's what my switch is set to and what I tend to leave the switch on. I have another single Walmart Everstart Maxx group 29 battery as my 'backup' that really doesn't see much use.
I have a prosport dual bank 20amp charger that I plug in once the boat is parked in the carport. (I used to use the cheap harbor freight float chargers, but finally stepped up to the more powerful prosport.)2008 Moomba Mobius XLV.

I do the same a Brett except I use bank 1 for everything and 2 for back up starting, one nice thing about the fusion is nothing seems to reset when batteries are off, just turn switch on and go

We discovered an interesting thing this weekend in regards to our dual battery switch. We have always run battery 2, well I decided to run battery one just to make sure it works. I selected battery one and went to start the engine and it cranked for like 5-6 seconds before starting. Crank speed was normal, it just didn't want to start. The rest of the day it ran fine, no problem. The next day I went back to battery two and it again, cranked for 5-6 seconds before starting. All subsequent starts were normal until I swapped it back to battery one, then it took 5-6 seconds to start. I am totally clueless on this lol
