One of the greatest metal bands on earth have a few stories to tell. From high school meet-ups to music festivals around the world, Avenged Sevenfold have done it all, remaining one of only a handful of bands that manage to essentially remain as their original lineup despite so much forward momentum.
This is because OBD II standards require O2 sensor PID voltage to be displayed in a range between zero and 1 volt. Newer vehicles will have accurate air fuel sensor voltages. * In generic OBD II what you often see is a percentage of true voltage.
To get the correct reading after a charge or discharge, rest the battery for 90 minutes before measurement. If this is not practical, overshoot the voltage on discharge or charge by 50mV. Discharge to 3.77V/cell or charge to 3.87V/cell, and the rubber band effect will settle the voltage at roughly 3.82V.
