I will have 2 and maybe three cars/SUV sitting in my garage this winter. The Norco has connections besides the clamps and battery ringlets being 12v cigarette plug can bus enabled and OCBD II to charge while Prologix has a 7 stage charge cycle including “exercising” the battery. Which one would you choose. The vehicles basically would sit from late November to March/April without being driven. Oil changed and tires filled to a little over spec’d pressures.
