Methods to test whether a car battery is good or bad: Before starting the vehicle, first use the voltage range of an analog multimeter to measure the no-load voltage of the battery. Typically, the rated voltage of a passenger car battery is 12V, and the no-load voltage is usually slightly around 13V. If the voltage is significantly lower, it indicates that the battery's health condition is not optimistic. A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. The battery commonly referred to as a car battery is a lead-acid battery, which is mainly made of lead and its oxides, with a sulfuric acid solution as the electrolyte.

What are the body dimensions of the Mercedes-Benz CLS?

The length, width, and height dimensions of the Mercedes-Benz CLS are 5001×1896×1430mm, which are official data. The length of the Mercedes-Benz CLS refers to the distance between two vertical planes perpendicular to the vehicle's longitudinal symmetry plane and respectively touching the outermost protruding parts at the front and rear of the vehicle; the width refers to the distance between two planes parallel to the vehicle's longitudinal symmetry plane and respectively touching the outermost rigid fixed protruding parts on both sides of the vehicle; the height refers to the distance between the highest point of the vehicle and the vehicle's supporting plane. The Mercedes-Benz CLS is equipped with a 2.0T version engine, with the engine model being 264920. The actual displacement is 1991ml, with 4 cylinders arranged in an L formation, and the intake method is turbocharged. The engine speed at maximum power is 6100 rpm, and the speed at maximum torque is 4000 rpm. The fuel supply method is direct injection, and it is recommended to use 95-octane gasoline. Both the cylinder head and cylinder block are made of aluminum alloy, which helps reduce the engine's weight and benefits the vehicle's lightweight design. There are national regulations regarding vehicle dimensions. According to the national standard "GB1589-89," the total width of a vehicle does not include side mirrors. The limitation on vehicle width is to provide sufficient lateral clearance for overtaking between adjacent lanes. This means that, according to national standards, the significance of vehicle width data is to ensure enough space during overtaking, preventing accidents due to excessive width or situations where road markings are narrower than the vehicle's width. Additionally, national regulations stipulate that the total width of a vehicle must not exceed 2.5m to meet the usage requirements of public roads.
