On July 16 I posted a new thread on problems I had when the 12 volt battery died. https://tinyurl.com/4ekfrhsj Electriceddy suggested that I install a BM2 battery monitor and report back. My BM2 has been monitoring the battery for a couple of weeks now. The image below shows the voltage over a 15 day period. The voltage goes up to about 14.7 volts and then gradually decays down to about 12.7 volts. The three periods indicated by the horizontal white lines represent three days when I made the same 3 short trips during the day. It looks like each time I take a trip, the battery charges at a voltage of about 14.7 volts. I think some, but not all, of the other spikes also represent trips. I'm not sure what the small negative spikes are. I have not taken any long trips, so I don't know whether the voltage would have stayed at about 14 volts or would have dropped back down. So far I have not seen a repetition of the battery going dead like it did in my original post. I'm still happy with the car in spite of the strange battery problem and the burning odor I still experience when I start it in the morning after it has sat for a few days.
