Default Leave an unplugged battery charger connected to lead-acid battery?

Thanks, but that wouldn't work for me. I need a battery charger for
recharging a boat battery (that operates the electric motor) after running
the battery down during a fishing trip. And, I sometimes need to be able to
leave the charger on for a week or more without it overcharging the battery.
So, I need a battery charger that will recharge fairly quickly but can be
left on the battery.

Thanks all.

Based on what everyone wrote, I've been looking for an "automatic"
battery charger. I checked Harbor Freight and one person suggested.

Here's the instruction manual for one Harbor Freight battery charger:

On Pages 8 and 9 of the manual, it talks about not leaving the
charger on and the possibility of the battery overheating with the
charger on. So, I'm a little confused. Does the automatic shutoff
actually work or not?


Check out any of the Sure Charge family as sold by Northern Tool.
I keep my generator plugged into one, 24/7. It starts when I need it
and has for the past 9 years [Same battery].
