I have a 2013 CT200h with 140,000 km. I just did the full meal deal diagnostic testing today. 87% on life expectancy and bad upper voltage on two blades.Yep, so the dash long-term mpg went from 37.1 to 44, keep in mind my battery health was at 49%. Not an exaggeration to say pretty much everything is better, seems to jump off the line at a green light now, handles better, brakes better. Drives more like a normal car than a hybrid, lugging around a heavy battery.
