Michael, good idea to return them. Bosch is decent to deal with on returns. As far as the wireless comment, Bosch has come out with a wireless charger and battery set up. I've got two and they are fantastic to work with. Unfortunately, regular Bosch batteries can't fit on the wireless charger because of a design in the case (it flares out to grab the walls of the charger.) I imagine there some electronics too, so it can communicate with the charger. You CAN charge wireless batteries on the regular charger though!
