new to the forum! I’m looking at a 09 Prius touring with 249k. I took screenshots of Dr Prius battery Health before and after test driving, how do they look? Thanks in advance!
Well, that's kind of like going into a doctor's office and the nurse takes your pulse and BP. It gives SOME info about general health but is very limited. (Not dead yet!) A more thorough test would be to drive the car - hard accel and braking while monitoring the VOLTage DIFFerence data. In general, a healthy pack has that value seldom going over 0.3V for more than a couple seconds, even at high discharge and charge amp rates. The paid (android, not sure about ios)) version of the app lets you record data to a csv file while driving, and does a "battery capacity guesstimate test". Posted via the PriusChat mobile app.
