I have a 2011 ford fusion
I have a 2011 ford fusion hybrid with 146K. Car runs good and has no issues that Im aware of. I read your explanation on hybrid batteries and have been getting myself mentally reading for the dreaded battery failure to happen sooner or later. I am pretty good mechanically and can fix most machines with the help of the internet.
Most all the info i have seen on the web pertains to the Prius/Toyota hybrid battery systems. Not much for the Fords. I dont want to tear into my battery without technical info about disassembly and reassembly.
Thank James
