When the 12V battery is measured, if it is lower than the normal voltage, then there may be some problems with the battery. When the car battery is 10.5V, it must mean that the battery is dead, but it is not necessarily completely broken. We can charge it first to see if it can be used normally after charging.
Battery status represented by different voltages
1. If the voltage is only slightly lower than 12V, the battery is basically fine if the voltage is above 11.5V and can be used normally.
2. IfDiscoverThe voltage is lower than 11.5v, but higher than 10.9v, which means that the car battery is currently in a state of depletion, and we need to charge the battery quickly.
3. But if the voltage is lower than 10.9v, it means that the car battery is completely out of power now, and there is also a certain degree of aging.
4. In addition, if the voltage is completely lower than 9V, it means that the car battery may be completely broken, and it cannot be used anymore, and there is no way to charge it normally. Then we need to go to a car repair shop or 4s shop to repair the battery or replace it with a new battery according to the actual situation.
The car battery is one of the most important components to ensure the normal running of the car. During the daily use of the car, we should also pay attention to the maintenance of the battery. For example, when the car is at rest and turned on, we should minimize the use of the car's electrical equipment, because these electrical equipment will also consume the battery's power. If the car is in a driving state, there is no problem with normal use, because the car itself can also charge the battery during driving.
