Car battery is dead how do _ Wei Li Po car battery (certified) _ car battery provided by Shenzhen Wei Lai Po Battery Limited. Shenzhen Wei Lai Po Battery Co., Ltd. (www.weilipo.com) is specialized in the "car batteries, car batteries, lead-acid car batteries," the enterprise, the company of "honesty, hard service" concept, to provide you with the most quality products and services. Welcome to inquire! Contact: Mr. Liu. Currently the car uses a lot of high-tech, its direction is mechatronics. Microelectronics promote the development of more electronic vehicle development to control the direction, making the car safer, more economical, and better handling, the car's performance to a higher level. At the same time, vehicle maintenance and repair work has become both easy and more difficult. Because the car is usually equipped with an electronic self-test system, a system fails, it can automatically alert the driver of the timely repairs, so you can take preventive measures, with special instruments can be quickly detected, and therefore make it easier for maintenance work . On the other hand, it requires maintenance workers must have the appropriate knowledge of high-tech car battery, and a dedicated test equipment, otherwise it can not start. From this point of view, it is more modern car repair difficult. For traditional automotive electrical parts, the main maintenance batteries, spark plugs, generators and other components. Because batteries are now commonly used lead-acid batteries, sulfuric acid liquid overflow easily What makes a good car battery, and sulfuric acid is highly corrosive, so be promptly wipe clean, taking care to not touch the eyes and skin. Sulfuric acid contained in the water will evaporate when the top surface of the liquid sulfuric acid near the stereotype, it is necessary to add distilled water. Of course, a lot of cars have adopted a maintenance-free battery, because the whole enclosed in a plastic case, reducing the maintenance workload. Batteries do not long, it will slowly self-discharge, until retirement. Therefore, at regular intervals should start a car car battery, to charge the battery. Another option is to pull the two electrodes on the battery down, pay attention to unplug from the positive electrode column, minus two electrodes line, first disconnect the negative cable, or remove the negative and the vehicle chassis connection. And then pulling the other end with a positive mark. When installing a new battery, just follow the reverse procedure to install, but it needs to be noted that, in the positive and negative adapter is installed follow the "first positive negative" sequence, as opposed to when dismantling, but the same principle , is to prevent the risk of a short circuit, security. ● Summary car battery is to determine whether the normal start of the important parts, but in fact it did not how precious car battery prices, it does not need to maintain it deliberately we need to develop good habits in everyday use, pay attention to some small details on it. Disassemble the replacement is not complicated, but important to note that when removing the need to dismantle the positive and negative connectors negative then positive, then the opposite is installed, to avoid the danger caused by improper operation.
