One tip....
....batteries like to "take a charge" after they are drained just a little bit.
Battery tenders work best, when the battery has been drained just a little bit down from full charge.
When you park your car, turn the headlights on after you shut the engine off and let the lights burn for about five minutes before shutting everything down and plugging in the battery tender.
The battery will then "accept the charge" and the circuitry inside the tender will recognize the state of charge and enter the proper charge/maintain cycle.
FWIW, the "Porsche" branded cigarette lighter chargers work great and can be found pretty cheap online.
Good luck.
