Both 12v and 24v car batteries exist, depending on the size of the battery and the configuration of the car. Generally, we can simply use the size of the car as a criterion. For example, the battery of a small car is 12v, and the battery of a larger car is 24v. However, judging by the appearance is relatively limited, and the specifics depend on the configuration of the car.
How to see whether the car battery is 12v or 24v
Generally speaking, if it is a diesel vehicle and uses a multi-cylinder diesel engine, its battery is usually 24v, and some single-cylinder diesel engines with relatively high horsepower will also use 24v. For most other gasoline-burning cars, the voltage of the battery is 12v.
What does the size of the car battery matter?
Whether the car battery is 12v or 24v is related to how we choose the charging rate for charging the car battery. To put it simply, if our battery is 12v, then we can choose a lower current for charging, such as 1.5A. And if it is 24v, you can choose a higher current for charging, for example, it can be increased to about 4A.
What should be paid attention to when charging
1. When charging the car battery, we should pay attention to the positive and negative poles of the battery need to be connected correctly with the positive and negative poles of the charger. If the connection is wrong, it will cause no way to charge normally;
2. After charging, if we want to unplug the charger, we need to unplug the negative cable first, and then unplug the positive cable, so as to avoid accidental electric shock.
