Seeking advice on care of hybrid battery

That's what I thought. So @bisco you would recommend balancing via something like the Prolong charger/discharger?

 

Well ed, I've never driven anything newer than an 07, so perhaps I don't have a good reference point. I bought my first Prius as an 07 in 2012. I was just saying that according to what I read on the Prolong Battery site, they are not showing those signs. As far as how they are maintained, they both were one owner vehicles with good service records, low miles, and are garaged. They do take short trips, which is not good I understand, but I'm not going to drive around in circles for half and hour to extend my commute. On the other hand, they have never been owned in areas of the country that get hot or have a lot of hills, mountains, etc.

Sadly, they are owned in a part of the country that gets very cold, and ironically, when I left after my prior post to go to my office, I found that the 12V battery was dead! Now I'll be starting a new thread about that.
