2. Know nothing about the power seat standby current, but know that C has got a smart battery management system. I noticed a few times that after I parked it in the garage, the fan nearby the battery turned on for quite long thime maybe 30 minutes or so. Opening any door or trunk lid will stop that fan but once door or trunk lid is closed fan starts again. Opening the hood will not stop the fan.
I measured my other cars when everything is turned off. Standby current is 70 mA on RX300, about 100 mA on RX300. Forgot what battery I have from Costco, but it will take about 3 weeks of no operation (no charge) to fail the startup.
C battery terminal is not easily accessable so I don't want to mess it up with my current measurement.
