Read the warranty book carefully.. the way I read it is the battery is warrantied for 8 years or until it fails.. Lot of good that will be. All batteries tend to fail. The battery without install is $5,000. Lot of risk for new tech. Otherwise I would probably get it.
So the power boost warranty is only 80K miles... or when ever it decides it needs replacement. I was looking at the location of the battery.. looks like you damn near have to take the truck apart to change it out! Anyone priced the battery itself yet?
