Yes. I had a Dodge Charger where the parasitic draw wouldn't really become problematic until 3 days after you re-attached the battery. At which point it would be so bad it would discharge from full to empty overnight. It could even out-draw a trickle charger. I took it to several mechanics who couldn't find anything - because they'd unplug the battery to add a meter into the circuit. They weren't willing to wait 3 days afterwards to come back to it. I ended up disconnecting the battery overnight. Worked fine then. Traded it in; I feel a bit bad for the next buyer.
