the charger i am using now is one of those pulse types that is supposed to do ????????
anyway, i just hook it up and charge away when i'm in the garage.
then, to make sure i unplug it when i go in the house, i have it hooked to a bright orange 14ga outside extension cord that is plugged into an outlet that is next to the door into the house. i can't miss that, so that works for me.
