How to install a new battery in a car?
The device that converts chemical energy into electrical energy is called a chemical battery, generally referred to as a battery for short. After discharging, the internal active material can be regenerated by charging-storing electrical energy as chemical energy; when it needs to be discharged, chemical energy is converted into electrical energy again. This type of battery is called a storage battery, also called a secondary battery. The so-called battery is an electrochemical device that stores chemical energy and releases electrical energy when necessary. The battery is generally composed of a charger, an inverter, a static switch, a battery and a control part.
How to install a new battery in the car? ? How much do you know about this problem? ? Today, the editor of Zhengzhou Kanglida Electronic Power Supply Co., Ltd. will give you some information on this issue. I hope it will be helpful to you. In the future, you can avoid detours when using and purchasing.
1. Before installing a new battery, if the brand and model of the battery are inconsistent, compare the dimensions and terminal positions of the new and old batteries, and carefully check the battery capacity and cold start current parameters. Especially in the northern winter, if the cold start current does not match, it may cause difficulty in starting the vehicle.
2. If conditions permit, a battery tester should be used for testing. After some batteries have been stored for a long time, although the voltage between the positive and negative ji is higher than 12V, the actual capacity is not enough, which is the so-called "virtual electricity". This battery needs to be charged. It should be noted that the measurement must be performed when the ambient temperature is higher than 0°C, and charging is performed when the ambient temperature is higher than 5°C.

3. Place the new battery in the installation position and fix it. For batteries with a vent tube, don’t forget to remove the vent tube connector from the old battery and install it on the new battery. For lead-acid batteries, pay attention to the inclination angle of the battery not to exceed 30° during installation.
4. When connecting the battery wiring, first connect the positive ji and then the negative ji. After installation, the battery terminal can be sprayed with anti-rust protective agent or acid-free grease for protection.
5. After checking and confirming that the fastening is reliable, the external power supply can be removed. Start the engine and check the voltage generated by the generator. It can be measured at the generator output or on the battery terminal. If there is a special diagnostic device, it can also read the voltage data in the data stream. In addition, it is recommended to measure separately when the engine is idling and 2000 r/min.
6. For vehicles whose batteries are replaced due to discharge failures, the vehicle's sleep current should also be checked. The traditional method is to place the multimeter in the current block, and then connect it in series to the negative ji circuit of the battery, lock all door locks, turn off the ignition switch and activate the anti-theft system, and let it stand for a period of time until the current stabilizes.
7. For vehicles equipped with a power management system, sensors are installed in the negative ji circuit. Such vehicles can only use devices such as clamp ammeters for current testing. Generally speaking, the sleep current of the vehicle should be less than 50 mA (according to the model maintenance manual, for example, some BMW models only require less than 80 mA).
8. After replacing the battery, the diagnostic instrument should also be used to clear the related fault codes recorded in the system. For vehicles equipped with power management systems, such as Mercedes-Benz, BMW, Audi and other German brands, it is also necessary to enter the new battery model in the power management system and perform a system reset.
9. After confirming that the electrical system is checked correctly, install the battery protection device, remove the body protection device, close the engine compartment cover or luggage compartment cover, and return the vehicle to the customer.
