What should I pay attention to after replacing the car battery?The new automotive battery may have insufficient electricity, including the original battery on new cars, which may be 100% power. Therefore, after replacing the new battery, or if you buy a new car, you need to make the engine run time long, so that the battery can be fully charged.
It is known that there is a 4S shop to replace the automotive battery. In addition to the pit in the 4S shop, the battery is also pit; not only the battery price is higher than the commercial sale, but also spends a lot of labor-hour fees. If you can buy it yourself, it is not only relatively cheap, but also saves the next time.
However, it is not difficult to replace the car battery, and the individual believes that the female owner can also complete. The tools that need to be used include a hexagonal sleeve and a "one" font screwdriver (different depending on different models).
Battery positive and negative disassembly order is quite
When removing the old car battery, it must be in the order of "first-removing the negative re-renewal", because the body is connected to the battery negative (iron end), if the right is removed first, the screwdriver is possible during the dismantling process. Touch the body, once it is touched, it is equivalent to connecting the battery positive and negative electrode, and it is possible to trigger a short-circuit burning battery. Therefore, it is necessary to "first negative the positive pole", but in the opposite direction, follow the order of "first positive electrode negative".
The automotive battery replacement process is simple
As long as the tool is ready, the relevant precautions are familiar, and the actual car battery replacement is very simple, and does not belong to what physical activity. At present, most of the models are located in the engine compartment (some pure electric vehicles are located behind the tail box), and some have a protective case outside, and some models are directly exposed to the outside. Take the MG5 model in the scene as an example, demonstrate how to replace the battery.
1. Loosen the negative electrode joint nut: turn on the two fixed buttons of the insulation cotton, you can see the red black two insulating hood above the positive negative connector, open the insulating hood, you can see the lock nut;
2, unpack the negative electrode joint: unscrew the fastening nut of the negative electrode with a wrench or hex hover, and then use a word screwdriver to slowly open the solid block, then pull out the negative connector;
3, unpack the positive electrode joint: unpack the positive electrode joint with the same method;
4, unlock the lock tape: Unscrew the nut for fixing the lock belt of the car battery, loosen the lock tightening tape, thereby removing the battery.
5. When installing a new car battery, just press the reverse step, but it is necessary to note that the installation of the positive and negative connector is followed by the order of "first positive electrode", in contrast, Like the principle, it is to prevent short-circuit danger and safeguard security.
Xiahua batteries include: tubular battery, colloidal battery, sealed battery, maintenance-free battery, OPZV tubular colloidal battery, OPZS battery, deep circulation battery
Automotive battery is an important component that determines whether the car can start normally, but in fact, there is not much more expensive, and does not need special to maintain it. We only need to develop good habits when we use, pay attention to some small details. . It is not complicated by self-disassembly and assembly, but it is necessary to note that the negative pole and positive electrode is needed, and when the installation is installed, avoiding dangerous due to improper operation.
