Car battery manufacturers | Wei Li Po car battery (certified) | automotive batteries supplied by Shenzhen Wei Lai Po Battery Limited. Shenzhen Wei Lai Po Battery Co., Ltd. (www.weilipo.com) is specialized in the "car battery, car battery, automotive lead-acid batteries," the business, the company adhering to the "honesty, hard service" concept, to provide you with the most quality products and services. Welcome to inquire! Contact: Mr. Liu. Battery role: 1, battery effect: in parallel with the generator to power electrical equipment. 2, when the engine is started, the starter and the ignition power supply system. 3, in the case of the generator not generating power or low voltage power to the electrical equipment. 4, when the generator is overloaded, to help power the generator 5, the electric storage battery is insufficient, and when the generator load and less production of automotive batteries, which power the generator can be converted into chemical energy stored (i.e., charge). 6, the battery is equivalent to a large-capacity capacitor (played a role in stabilizing the vehicle system voltage) is the main role of automotive batteries? The battery of the vehicle, also known as batteries, the chemical energy is converted into electrical energy equipment. Its role is at engine start, the engine ignition system, and other power devices. Further, when the engine is not running or the power generation system can not meet with the electrical output power, the battery can power the device for a certain time up electrically. What is the relationship between the battery of my car? In addition to auto starter car battery, battery with a lot of related car battery with electrical appliances, such as lamps, lighting, wiper, speakers, navigation and so on. These batteries can be stabilized voltage electrical appliances to avoid voltage fluctuations caused by abnormal working or damaged. When the engine is not running a car battery which brand is good, the car all the electrical power provided by the battery. When the engine is at low speed, idling, and the power output of the system can not meet with the electrical power, the battery will assist with the electrical generator to make electricity.
