Remote Sense

Remote Sense can reduce battery charge time by 50%. Some 35SI models are equipped with Remote Sense which utilizes a second wire that reads the actual to boost its output to compensate for the voltage drop, ensuring 14 Volts at the battery. The proper voltage forces more current into the battery bringing it to a full state of charge between vehicle stops.
