Why does the effectiveness of a car battery seem to drop off rather sharply when the voltage gets a bit below 12? I would think it would be more or less a linear decay of current ( I = V/R etc). Thus one would think that the current generated would be proportional to the voltage but anyone who's tried to start a car, listen to the radio etc on something like 11 volts knows it's pretty dead.
So what gives?
