I am a little confused on the purpose of the so called Motorcycle 12 volt battery. I have been trying to digest just what the purpose is, from that Yahoo message board. Is it used only for starting and maintaining the screens, computers, anti theft stuff etc??? The reason I am concerned, is because when my wife goes shopping, sometimes I sit in the car and play the radio for an hour or two with the ignition swictch in accessory. Now is this radio running on the 12 volt battery or the Hybrid battery??? Also, what about other accessories like Fan, wipers, window up & down etc??? If the ready light is on and I switch to Accessory, the Monitor stil shows the data and Green battery. If I lock first, and then switch to Accessory, The monitor shows no green on the battery. These are just a few observations. Also, sometimes the drivers window will operate and other times it will not???
