What Battery Voltage Is Required To Start A Car. The battery energy required to start the vehicle may not be replaced by the alternator simply by idling the car in the driveway for a few minutes. If the voltage falls below 124 V the battery should be recharged as soon as possible.
But in the case of SUVs Trucks and cars with bigger engines you will need about 1000 amps. At the time of exploitation this parameter is between 137 to 147 volts.
