I have a heavy (65 lb) battery for my boat & live upstairs (no elevator) in a condo.
I don;t wanna keep bringing it inside to charge it & the only power plug I have outside is where I park my car. There is no power where I store the boat.
I have 2 cars, so could always take the good battery out of the car & put the dead battery in & charge it that way. What do u suggest?
