Should the car battery be replaced after 5 years?Can the car battery still be used after 6 years?

The life of a car battery is about 3 years, but many car owners don’t know whether they should replace the car battery after 5 years.

These batteries are equipped with power observation ports. Green means sufficient power, black means a slight loss of power, and white means that it is scrapped and needs to be replaced.

Can the car battery still be used after 6 years?

The car’s battery does not have a fixed replacement cycle, which is very similar to the car’s brake pads. The car’s battery life is mainly related to the frequency of the car, the driving distance each time the car is used, and the related maintenance problems of the car. A big relationship, that is to say, as long as the car’s battery does not have any major problems and does not affect the normal use of the car, the car’s battery can be used for 6 years.

The service life of a car battery is closely related to the maintenance of the battery by the owner. The maintenance methods are as follows:

1. When driving the vehicle, the battery will be charged, and the owner who needs to park for too long should start the engine regularly to avoid the battery loss due to the long-term parking of the vehicle;

2. Unplug the positive and negative connection wires of the battery to prevent the battery power from draining. There is no need to start the engine regularly, and you can park the vehicle for a long time. The sequence when removing the positive and negative connecting wires is very important. First, unplug the negative wire, and then unplug the positive wire. The connection and installation sequence is exactly the opposite of the removal sequence, first connect the positive pole and then the negative pole;

3. Clean the terminals on the battery every once in a while, and apply special grease to protect the wiring harness, and regularly check the accessories and connection lines of the battery;

4. Try not to use on-board electrical appliances after the car is turned off. The engine uses the battery alone when it is not generating electricity. After a night of consumption, the car may be out of power at any time and cannot start the car, resulting in battery power loss;

5. It is forbidden to start the car repeatedly, otherwise it is easy to cause the loss of the battery. Every time you start, the ignition time is controlled at 3 seconds. If it fails, you must wait at least 15 seconds for the restart time. If you can’t start it three times in a row, you must find other reasons. start up.
