I ended up buying a NOCO due to the experience of having a dead vehicle that had to be towed to the dealer and after 4 days W/O a loaner it was returned to me stating "the battery was charged" . I'm in the market for another vehicle.
I had exactly same experience DEAD BATTERY - TOWED TO FORD - they chargedthe battery & said it was OK. Now I'm concerned to drive it & will probably get rid of it!
