Is the battery ah bigger the better?Hazards of replacing a car with a large-capacity battery

Generally speaking, there is no harm when replacing a large-capacity battery in a car. As long as the voltage of the replaced large-capacity battery is stable and does not exceed the standard, replacing the large-capacity battery will not affect the electrical equipment. However, if the volume of the large-capacity battery is If the base of the car is not matched, it will not be installed, and it will also affect the normal driving of the car.

Is the battery ah bigger the better?

The larger the battery AH number means the greater the battery’s power, but the battery’s quality is not only based on the battery AH indicator. The battery’s output power is large, the discharge time is long, the number of charge and discharge times, self-discharge, internal resistance and the battery Coefficients such as weather resistance all determine the battery level, so we can't just say that the larger the battery AH, the better.

Ah is the capacity unit of the battery or electric board, which affects the running time of the motor. AH has nothing to do with the current. The national standard stipulates the battery capacity as a 20-hour discharge rate. A 120AH battery is discharged with a current of 6A and can be discharged for 20 hours.

Car battery maintenance

1. Avoid parking the car in the open-air parking lot for a long time. If it is parked for a long time, the battery must be removed to prevent the battery from icing and damage;

2. The car engine is not easy to start in winter. The time to start the car should not exceed 5 seconds each time, and the interval between restarts should not be less than 15 seconds. Look for the reasons in other aspects such as roads, and avoid multiple uninterrupted starting, which will cause the battery to burn out due to over-discharge;

3. The car battery should be charged frequently. The battery will slowly discharge by itself until it is scrapped if it is not used for a long time. Therefore, the car should be started to charge the battery every once in a while;

4. Clean the battery terminal at regular intervals and apply special grease to protect the wiring harness. Check the accessories and connection lines on the battery frequently;

5. It is forbidden to use automobile electrical appliances after the car is turned off. Using the battery alone when the engine is not generating electricity will cause damage to it.
