I have a three bank charger on my boat - with a cranking battery and two deep-cycle batteries. I understand that if I come in from the lake, I can hook the charger to the AC. What happens if I do not plan on using the boat for a week or two? Will leaving the charger pluggted on the AC hurt the batteries or will it simply be a trickle charge and then shut off when fully charged?
I thank you for this board for us newbies and appreciate your ideas.
Thanks in advance.
