Current flow in batteries?

$begingroup$ Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics. Not noticable at most voltages, but see what happens when you touch a peice of metal to a 100,000kV line, even in a vaccumm with no earth, a sizeable current will flow to bring the metal to the same electrostatic charge.

Can a Battery Drain with the Negative Cable Disconnected?

A car battery will naturally "self-discharge" at a rate of 5-15% per month with the negative cable disconnected but is the best option for long-term parking if you cannot hook it up to a charger. Leaving the battery hooked up will drain it at 20% or more per week.
