Run the battery for 2 hours to full
Due to the influence of many factors such as battery power, engine speed, electrical power consumption and so on, it is unreasonable to use the number of kilometers traveled by the car to judge whether the battery is full.
1, under normal circumstances, the car engine to maintain more than 1500 RPM charge for more than 60 minutes, and then maintain more than 1900 RPM charge for more than 60 minutes, you can be half of the battery is basically full.
2, the battery power is less than half, that is, when the voltage is lower than 13.4V, the car is difficult to start, and the battery warning light is on.
3, the car driving on the highway, in the basic do not turn on high-power electrical appliances, such as air conditioning, headlights, etc., after 2 hours, the battery is basically full.
4, in actual use, the battery can not be really full, the reason is:
a, the battery needs to have the so-called \"trickle\" charging, in order to fill the battery, that is, full,
b, the car generator in order to meet the operation of the vehicle equipment, the output of a large current, far more than the best charging current of the battery, this current can not fill the battery,
c, the car driving process, the electricity consumption is not uniform, the battery may always have current in and out.
