If the car's alternator fails, how long will the battery last?

The car's alternator is broken. The electricity from the battery can be used for about half an hour. The duration of use varies depending on the model. 1. Vehicles with fewer body functions will have longer battery life when the generator is not producing electricity. For example, in a truck, although EFI continues to use electricity, there is no other comfortable computing power, so it does not generate electricity. can be used for half a day when the generator runs on electricity. 2. If the generator is not producing electricity, the battery power will continue to decrease. When the battery voltage is below 9 volts, the engine computer will not operate properly. Symptoms include: steady idling, difficulty accelerating, then. the idle shakes until it automatically turns off. Therefore, when it turns outthat the generator does not produce electricity, it must be repaired in time to prevent the vehicle from breaking down halfway.

The power generated by the truck's generator is 30 volts, which is abnormal. There are two batteries connected in series on the truck. The rated voltage is 24 V. The generator voltage does not exceed 29.5 V. The normal power output of the car generator is between 12.6 volts and 14.5 volts. the floating charge voltage of the 12V battery.
