i do the same as Lynmore. Cept I leave the tender on all the time. DelTran info says that is the way to go.
DelTran says that it may be left connected all the time. From their website:
How long can I leave the Battery Tender® Plus battery charger connected to a battery?
"In theory, you can leave the Battery Tender® Plus battery charger connected to a battery forever. That’s a really long time. Sales people like to say, “Just plug it in and forget about it!” However, practically speaking, it is a good idea to check on the battery at least once every couple of weeks. Strange things can happen. Sometimes a battery can have a weak cell that won’t show up until the worst possible time. Of course, that time is usually when the battery is connected to a charger, and you are out of town on vacation."
The full charge indicator comes on at 85% charged so I leave it float for some additional time, thus the three days. Since I have nine seasonal batteries, I constantly rotate the charger among them rather than buy a charger for each. With the quick disconnect pigtails, it is a simple matter to swap between batteries and I can disconnect entirely when storms threaten or will not be home for an extended period of time.
Those that use the converter should know that the detectors, radio, TV, refrigerator, thermostat, microwave and other systems are connected to the grid and are subject to damage even with a fancy EMS.
