Question about the "desulfator gizmo":
This devise supposedly works by periodically zapping the sulfated plates with "high-frequency AC"...so I'm wondering if this will damage the electronics in modern cars. The articles/videos I've seen don't mention if the battery has to be disconnected from the car (thereby losing all the presets and computer memory) during the zapping process.
I disconnect the battery on any car with an ECU if I am going to use a charger at more than 20 amps for this very reason.
