In order to determine the length of time that an automotive battery will last when using an inverter pulling 1,500 watts of power, you will need to know the amp hours of the battery that you plan to use. For that much wattage though I can't imagine very long if it's a standard battery.
Since 12 watts = 12 volts that means that you'd need a 125 amp hour rated battery to power the blender for one hour.
1,500/12 = 125
