According to the national standard, the regulated voltage of a 12 V generator is 14.5 ± 0.25 V
That is to say, under normal working conditions, the maximum working voltage of the generator is 14.75V
p>According to national standards, the test voltage of the generator at full load is 13.5±0.1V
That is, under normal operating conditions, the generator voltage will not be less than 13.4 V
So, under normal circumstances, the generator voltage is between 13.4 and 14.75 V.
The general model of Chevrolet LeFeng car battery is 46B24L Haoqing.
The battery is most afraid of low temperatures. In a low temperature environment, the battery capacity is much lower than that at normal temperature. Therefore, we should check and maintain in time, and pay attention to the following points in daily life:
Avoid parking the carin an open-air parking lot for a long time. for a long time, the battery should be removed and taken away to prevent freezing and damage.
The car engine is not easy to start in winter. The car starting time should not exceed 5 seconds each time, and the interval between restarts should not be less than 15 seconds. If it still does not light up after several starts, the cause should be looked for in other aspects such as the circuit, ignition coil or oil circuit. Avoid starting multiple times without interruption, as this may cause the battery to drain due to over-discharge.
Car batteries need to be charged frequently. If the battery is not used for a long time, it will discharge slowly until it is discarded. Therefore, the car must be started from time to time forreload. battery.
Clean the battery terminals from time to time and apply special grease to protect the wiring harness. Always check accessories and connection lines on the battery.
It is prohibited to use car electrical appliances after the car is turned off. Using the battery alone when the engine is not producing electricity will damage it.
