Steve Schroeder Posted July 25, 2012 Report Share Posted July 25, 2012 I bought a BatteryMinder charger from Sporty's. The instructions say to disconnect the battery before charging but at the same time they provide ring terminals to permanently attach charging leads to the battery. I think the disconnect advice is CYA on their part. Question: Do I need to disconnect my battery when I charge it? Mu gut tells me no. I think if the master switch is off then it stands to reason it could do no harm to avionics etc.... For the record I fly a PiperSport not a CTLS, but I find this forum very helpful.
