This is probably due to deep discharge. That is to say, when the vehicle is turned off, the vehicle equipment inside is still in working condition, resulting in continuous consumption of battery power. Over time, this will definitely make the problem worse. Degradation of the car battery. Sometimes there will be a situation where the battery is discharged.
The second reason is the aging of the generator belt. You should know that the engine directly drives the generator through the belt, and then the electricity it sends is straightened and stabilized, and directly charges the car battery.
So if there is an abnormality in the belt at this time, it will naturally lead to a situation where it cannot be loaded and it needs to be replaced in time.
But this factor will practically not occur, because the generator belt will be checked for you during an major maintenance of the car. If it ages to a certain extent, it will be replaced with a new one for you.
The batteries used in cars are all lead-acid batteries. If they cannot be loaded, it may be due to vulcanization of the plates.
For batteries that have been used for a long time (more than three years), there is virtually no repair value. Simply replace it with a new one if it is a battery that has been used for a while. little time, due to the short time. Slight vulcanization of the plates caused by overdischarge can be repaired by desulfurization and charging, but the battery capacity can only be restored to about 80% of the rated capacity.

Are the generator belt tensioner and booster pump belt tensioner of Teana 2.0 identicalues
1, open the engine cover and find the location of the generator and belt.
2. Use a wrench to loosen the generator's adjustment screw or tensioner to loosen the belt.
3. Remove the original belt and pay attention to the installation position and direction of the belt.
4. Remove the new belt and install it correctly according to the installation position and direction of the original belt.
5. Use a wrench to adjust the generator tensioner and tighten the belt. At the same time, pay attention to the tightness of the belt. Don't be too tight or too loose.
6. Start the engine and observe if the belt operates normally. If there is any abnormal noise or beating, stop the vehicle immediately to check or readjust the belt tension.
7. Close the engine cover and check if it is firmly seated and the belt is installed correctly.
Not the same. The size and structure of the Teana 2.0 generator belt tensioner will be different, because different belts require different tensioning forces and tensioning methods. The generator belt tensioner is used to adjust the tension of the generator belt to ensure the normal operation of the generator; while the booster pump belt tensioner is used to adjust the tension of the booster pump belt to ensure the normal operation of the booster pump. normal operation.
