What Current Should Be Set When Charging a Car Battery?

When charging a car battery, the appropriate current depends on the battery's capacity. Generally, the smallest car battery is 36AH, while the largest can be 80AH. For a 36AH battery, a charging current of 4 to 8A is suitable, whereas an 80AH battery requires 8 to 16A for optimal charging. Lifespan of a Car Battery: Under normal usage conditions, a car battery typically lasts between 3 to 8 years. Over time, its internal resistance gradually increases due to sulfation, and its capacity diminishes. Precautions for Using a Car Battery: Always keep the battery clean and dry, ensuring the vent holes remain unobstructed. Avoid continuous use of the starter motor; each use should not exceed 5 seconds, with a 10 to 15-second break between attempts. A fully charged battery with sufficient electrolyte should not be left in a state of undercharge for extended periods. Regular charging is necessary to prevent permanent damage.

Under what circumstances should wheel alignment be performed?

Wheel alignment should be performed in the following situations: damage to the chassis and suspension, tire wear, removal of axle or suspension components, and vehicle pulling to one side. Wheel alignment is based on the four-wheel parameters of the vehicle, and adjustments are made to ensure good driving performance and a certain level of reliability. The purpose of wheel alignment is to maintain stable straight-line driving and easy steering, while reducing wear on tires and steering components during driving. Unlike regular maintenance, wheel alignment is a repair procedure and should only be performed when there is an issue with the vehicle. It is not necessary to perform wheel alignment if there are no problems with the vehicle.

Where to Handle Vehicle Annual Inspection?

Vehicle annual inspection can be handled at local vehicle inspection stations or the vehicle management office. Annual inspection refers to the annual or biennial safety inspection of vehicles, which includes a comprehensive check of components such as the horn, brakes, axle weight, chassis, ignition system, lighting system, exhaust system, and license plate installation.

If any items fail, the owner must repair the vehicle and undergo a re-inspection until all items pass before proceeding with the annual inspection. Failure to undergo the annual inspection on time may result in denied claims for accidents or lost vehicles, along with a fine of 200 yuan and a deduction of 3 points from the driving license.

How to Clean Engine Sludge?

Engine sludge cleaning method: Generally, 4S shops clean engine sludge by adding a cleaning agent to the engine lubrication system. Before changing the oil, the sludge cleaning agent is poured into the engine through the engine oil filler port, and the engine is started to maintain idle operation for 5 to 10 minutes. Then, the engine is turned off, and the sludge cleaning agent is discharged along with the engine oil. During engine operation, the high-temperature working environment, wear from the relative movement and friction of various surfaces, and the combustible mixed gases entering the crankcase from the cylinder can all affect the performance and quality of the engine oil.

Can You Pick Up the Car on the Same Day of Purchase?

Whether you can pick up the car on the same day of purchase depends on whether the 4S store has the car in stock.

If the store does not have the car in stock, you will need to wait, and the waiting time is uncertain, influenced by many objective factors. When picking up the car, be sure to inspect the vehicle to prevent any issues, mainly checking for scratches on the exterior, ensuring the interior is not dirty, etc. You should also start the vehicle to check if the lights are working properly, if all electronic instruments are functioning correctly, and if the wipers, turn signal lever, dashboard, etc., are in good condition.
