Is a 13.4 Volt Normal Car Battery Voltage When the Engine Is Running or Too Low?
When your car's engine is running at idle, the battery should typically maintain a voltage between 13.5 and 14.5 volts. When the battery is fully charged but the engine is turned off, the voltage should read around 12.6 volts.
If your car battery voltage is only showing 13.4 volts when the engine is running, it may be an indication of a weak battery or alternator. A weak battery will not be able to hold a charge and will eventually need to be replaced. A weak alternator will not be able to generate enough power to keep the battery charged and will eventually lead to the battery being drained.
It is important to have your car battery and alternator checked if you are experiencing any issues with your car's electrical system. A qualified mechanic can diagnose the problem and make the necessary repairs.
