Does anybody know how these boost packs really work?
Say a car's battery is run down (~11.0 Volts) and you hook up the boost pack (Guessing it's ~ 12.6Volts).
Does the pack immediately start "charging" the low battery? It must right? Or is there some electronics (an a heavy duty contactor or SCR that can switch ~1000amps?) that detects car is trying to start? (i.e. if the voltage drops even lower (~<10 volts, etc..). -This seems unlikely.
Is there a danger with these packs of them bouncing around in the trunk and the red clamp touching the black clamp, or the clamps touching the car body at the same time?
