What do you do with your boat batteries?

[Kent]

For years, I have left the batteries on my boat without any problems. I have an on-board charger for the trolling batteries only. Once a year, I check the water level and I make sure all of the batteries are fully charged when the boat is put away for the winter. While it is in storage (my boats have always been stored outside) I plug in the on-board charger and also charge the starting battery about every 3 months.

I am going to miss my Perko Switch (that I had on my previous two boats).
