    After the car starts, the voltage should generally be lower than the battery may not be able to charge the battery, please check the load of the engine or other electrical appliances. When the voltage is greater than the battery may be damaged, please check the engine stabilizer. The voltage of the car's battery without starting the engine is.

    If it is more difficult to start the car when it is lower, please turn off other electrical appliances as soon as possible, and when the voltage of the battery is lower than 10V, it will generally not be able to start the car.

    1. Avoid parking the vehicle for a long time. When the vehicle is parked for a long time, the battery power loss will not be replenished, and the voltage will drop.

    2. Don't forget to turn off the electrical equipment in the car when you lock the car. Remember to turn off the headlights, air conditioning, and more when you get out of the car.

    3. Do not turn on the air conditioner for a long time when the vehicle is idling or turning off.

    Fourth, the vehicle could not be started due to other failures, and the owners fired it many times. If the owner keeps igniting for many times in a row, the battery will continue to be discharged at high voltage, which will also cause power loss. There should be an interval when starting the vehicle, and the time of each ignition should not exceed 5 seconds, and the interval between continuous ignition should be more than one minute.

    Under normal circumstances, the no-load voltage of the car battery is about 13V. If it is lower than 12V, it means that the battery is in an aging state. If the no-load voltage is lower than 11V, it basically means that the battery is about to be exhausted.

    The end point of battery discharge is 10.5 volts, and the end point of charging is 13.5 volts, both of which are normal, which is related to how much electricity is left in the battery pond. The battery discharge capacity is poor in winter, and 11 volts are required for ignition, and 5 volts at 10 o'clock in summer are OK. It is not possible to generalize due to factors such as vehicle condition, fuel (gasoline, diesel), temperature, altitude, etc.

    The battery voltage standard is 24V.

    1.The battery voltage standard is 24V, but if fully charged, it should be 2 to 3V higher than the battery voltage, but it will not exceed the maximum output voltage of your generator 28V, because the battery is charged by the generator, but if the battery is not charged for a long time, and you use it often, then the battery voltage will slowly drop to 24V, or even lower.

    2.When it drops to 20V, you are connecting the generator and charging, then the voltage at this time may be around 23V or 24V, when the power is slowly full, the voltage will go up to more than 24V, or 28V, so the voltage to the battery depends on how much power your battery has, not a fixed one, theoretically when the battery power is saturated, the voltage of the generator to the battery can not be lower than 24V.

    3.Voltage, also known as potential difference or potential difference, is a physical quantity that measures the difference in energy between a unit charge in an electrostatic field due to different potentials. This concept is similar to the "water pressure" caused by the high and low water level.

    It should be pointed out that the term "voltage" is generally only used in electrical circuits, while "potential difference" and "potential difference" are generally applied to all electrical phenomena.

    The battery voltage of the car is usually 12V or 24V, and the battery voltage of the car of the general household gasoline engine is 12V, while the working principle of the diesel engine is different from the gasoline engine, which requires a higher voltage, so the battery with a voltage of 24V is mostly used.

    However, the 12V battery voltage is not fixed and will generally be larger. Under normal circumstances, the battery voltage before the car starts is between, and the battery voltage after the start is between, as long as the voltage at the start is not lower than 11V, it is considered a normal voltage.

    (Battery voltage comparison table).

    If the battery voltage is too high or too low, it will have a certain impact. The use of the battery should be checked more often, and once the battery voltage is lower, it needs to be charged in time. If the battery voltage is too low, the car will be difficult to start or even unable to start;If the battery voltage is too high, the battery may be damaged.

    The battery can be charged by the generator while the car is driving, and if the car is parked for a long time, it is easy to cause the battery to lose power, causing the car to not start. Therefore, during the long-term parking period of the car, it is best to start the vehicle every other week, and the generator will charge the battery, which generally needs to idle for more than 5 minutes. In addition, when parking for a long time, it is recommended that the owner take off the negative pole of the battery, because even if the battery is not used, it will be discharged naturally, and this can avoid the loss of the vehicle battery.

    For the natural discharge of the battery, also known as the self-discharge rate, it means that it will lose about 1% of the power every day without connecting any electrical components and without any load. The size of the self-discharge rate is directly related to the quality of the battery, the better the battery, the purer the electrolyte, and the smaller the self-discharge rate. Therefore, try to avoid using the electrical appliances in the car after the car is turned off, because the use of electrical appliances when the engine does not generate electricity will always consume battery power, and the battery power loss will affect the start of the car.

    The batteries of ordinary cars are basically 12V. The battery is a vital part of the car, and without the battery, the car cannot function properly. When the engine is not starting, the battery is responsible for supplying power to the entire car's electronic devices, and the battery is also responsible for starting the engine.

    When starting the engine, the starter, ignition system, fuel supply system, etc. basically need Genting, and the operation of these systems is inseparable from electricity. If the battery is dead, the engine will not start properly. After starting the engine, the engine will drive the generator to run, and the generator can supply power to the electronic equipment of the whole car when it is running, and the generator can also charge the battery.

    The battery is a wearing part that needs to be replaced regularly, and the performance of the battery may continue to deteriorate as the number of charging and discharging times increases. During charging and discharging, the ions in the battery move in the electrolyte, and some ions react chemically with the electrolyte as they move in the electrolyte. As the number of charge and discharge times increases, the number of ions in the battery may also continue to decrease, and of course the performance of the battery may also continue to decline.

    If you can maintain accurate car living habits, this can still have the effect of extending the service life of the battery. It is recommended that friends must not use the electronic equipment in the car for a long time when the engine is not started, and it is not necessary to turn on the headlights and air conditioning and other power-consuming equipment in the car at the same time when starting the engine.

    The normal range is.

    In the no-load state, the normal voltage of the car battery is about 13V, and the load voltage is not less than 11V. Below this voltage may be difficult to start, after starting, the normal voltage of the car battery should be between because the generator starts to generate electricity.

    However, now many battery cars and cars have been equipped with automatic alarms, so if they are not charged in time, and after a long period of time, the car and battery cars themselves will consume the remaining power, causing obstacles to the next start, therefore, if there are cars and battery cars that need to be parked for a long time at home, they need to be started every other week, and it should be noted that each start should last more than five minutes.

    It is not normal before activation. Generally, this voltage is about 14V.

    The voltage after the car is turned off for a period of time (more than 20 minutes), that is, the voltage before ignition. This voltage is usually around 12V. In general, it is difficult to start ignition if the discharge voltage is less than 11V (if the discharge voltage is usually less than 11V, the battery may be severely depleted or aged).

    At the moment of ignition, the voltage will drop to a certain point instantly, and the lowest is the starting voltage, which is generally. If the starting voltage is usually lower, the battery may be severely depleted or aged. The charging voltage refers to the state of charge after the ignition engine of the car is started.

    According to the service life, there is no need to change.

    There is no need to change it according to the voltage.

    But you have to pay attention:

    If it is a frequent short distance, it must be maintained once a month, and try not to use too much electrical equipment while driving, and turn off all electrical equipment after parking.

    At the same time, you should check if there is any leakage, my battery has been used for six years, in fact, if you barely use it for a summer, it will be fine, but I still changed it on the seventeenth day of the first month. But I was reluctant to do it, because there were still plates that were good.

    The specific number, I have filmed it before** and forgot, and mine should also be maintained.
