what would happen if you put a battery charger on both batteries without isolating them?
 
or if you didnt isolate them and put a charger on just one battery? My batteries keep dying cause i dont drive it. I dont want to have to unhook them everytime i get back from driving it. I drive it about once every 3 months.
 
It will charge both batteries. Just like the alternator does.
