Car battery removal and installation sequence: 1. Turn off the ignition and remove the key; 2. Disconnect the negative battery terminal and remove the positive terminal protective cover; 3. Disconnect the positive battery terminal and remove the battery securing device; 4. Remove the battery, and perform the installation in reverse order. A car battery is a type of storage battery that converts chemical energy into electrical energy, including lead-acid batteries, nickel-iron batteries, and nickel-cadmium batteries. In a lead-acid battery, the positive electrode is lead dioxide, the negative electrode is lead, and the electrolyte is a dilute sulfuric acid solution. During discharge, the positive and negative electrodes react with sulfuric acid to form lead sulfate. When the sulfuric acid concentration drops to a certain level, the battery must be recharged. Using an external power source to recharge can restore the electrodes and solution to their original state, allowing the battery to be used again after charging.

What Causes Slow Car Idling?

Common causes of slow car idling are as follows: 1. Oil accumulation and carbon deposits in the throttle body, or a dirty intake manifold: As the vehicle is used over time, the intake manifold may become clogged, and carbon deposits or oil may accumulate in the throttle body, leading to unstable idling or even low idle speed. Carbon deposits in the throttle body can affect the air intake volume, causing low idle speed when the car is started cold. 2. Weak spark due to faulty spark plugs: Over time, spark plugs can also develop carbon deposits. Severe carbon buildup can cause weak sparks in individual cylinders, affecting the car's performance and resulting in low idle speed. It is recommended to clean or replace the spark plugs promptly. 3. Malfunctioning idle control valve: When the car's related sensors fail, the air-fuel ratio becomes incorrect. Common sensor failures include the coolant temperature sensor, oxygen sensor, and throttle position sensor, leading to high fuel consumption and low idle speed.
