How Long Does a Refurbished Battery Last?

Refurbished batteries generally last 3 to 6 months. Daily Inspection: First, check if there are any obvious leaks or deformities on the battery's exterior. If deformities or leaks are found, replace the battery immediately to ensure driving safety. If no issues are detected, properly connect the battery's positive and negative terminals, then turn on the vehicle's electrical self-check to see if the battery's electrolyte level needs replenishing. If replenishment is required, use distilled water or a special dedicated liquid—never use mineral water or tap water. When starting the engine, note that the cranking time should not exceed 5 seconds, and the interval between attempts should be no less than 15 seconds. If the engine fails to start, check if the ignition coil is aged or malfunctioning. Routine Maintenance: Regularly clean the battery. Use a damp cloth to wipe the battery's exterior, removing dust, grease, white powder, and other contaminants that could cause leakage from the terminals and panel. Frequent cleaning prevents excessive buildup of acidic corrosion powder on the terminals and extends the battery's lifespan. Applying specialized grease to the terminals can also help protect the battery.

What is the solution when a car cannot shift gears after wading through water?

The solution when a car cannot shift gears after wading through water is to pull the handbrake while the car is turned off, then shift into first gear or reverse gear; after starting the engine, release the handbrake, and shift to other gears while the car is moving. After turning off the car, start it again to return to normal. Possible causes of the issue: Internal failure of the gear shift lever assembly; malfunction of the P-lock solenoid valve inside the gear shift lever or failure of the brake switch; incomplete clutch disengagement. Precautions: When driving through water, ensure the engine is running normally, and the steering and braking systems are responsive and reliable. Maintain steady throttle control to provide sufficient and stable power for the car to pass through in one go, avoiding stopping, shifting gears, or making sharp turns midway, especially when the underwater surface is sandy or muddy. Keep an eye on both distant and nearby surroundings to prevent the vehicle from deviating from the correct wading path and causing accidents.

At what millimeter thickness must brake pads be replaced?

Brake pads should be prepared for replacement when their thickness is less than 0.5cm. Conditions requiring brake pad replacement: If a metallic scraping sound (like iron rubbing against iron) is heard when lightly applying the brakes, the brake pads must be replaced immediately. This indicates that the wear indicators on both sides of the pads are already directly grinding against the brake disc, proving the pads have exceeded their limit. If braking feels unusually difficult, it likely means the pads have lost most of their friction and must be replaced to avoid serious accidents. Tips to extend brake pad lifespan: Emergency braking causes significant damage to brake pads. When driving normally, practice gradual braking or use the pulse braking method to minimize wear. Develop good driving habits to reduce unnecessary braking - first use engine braking to slow down before applying the brakes for further deceleration or stopping; downshifting can also help with speed reduction. When the vehicle shows alignment issues like pulling to one side, get a four-wheel alignment promptly to prevent tire damage and uneven brake pad wear on one side.

What is the correct way to connect car battery cables?

Car battery cables should be connected positive to positive and negative to negative. Battery cable connection procedure: First, clamp the red cable of the jumper wire to the red positive terminal of the "disabled vehicle". Then clamp the other end of the red cable to the red positive terminal of the "rescue vehicle". Clamp the black cable to the black negative terminal of the "disabled vehicle". Next, clamp the black cable to the black negative terminal of the "rescue vehicle". Start the engine of the "rescue vehicle" first, then start the engine of the "disabled vehicle". If the disabled vehicle still cannot start, check whether the metal contact parts have poor contact. Cable removal procedure: First, remove the black cable from the "disabled vehicle". Then remove the black cable from the "rescue vehicle". Next, remove the red cable from the "rescue vehicle". Finally, remove the red cable from the "disabled vehicle".

What Causes Idle Shaking When the Car Gets Hot?

Reasons for idle shaking when the car is hot include severe engine carbon buildup; ignition system issues; unstable oil pressure. Severe Engine Carbon Buildup: The most common cause of car shaking is a dirty throttle or excessive carbon buildup in the fuel injectors. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold-start injector is largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making it difficult to start. Ignition System Issues: Check the working condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or inadequate spark plug firing can also lead to such faults. Unstable Oil Pressure: If you have already cleaned the engine carbon buildup, cleaned the throttle, replaced the oil gasket and spark plugs, but still notice body shaking at idle, it is recommended to visit a 4S shop to check whether the fuel supply pressure and intake pressure sensor are functioning properly. Abnormal fuel pump supply pressure or incorrect readings and poor performance of the intake pressure sensor can all cause body shaking.

How to Handle Traffic Violation Points on Mobile Phone?

Traffic violation points can be processed through the Traffic Management 12123 mobile app. Users can follow the instructions on the violation handling page of the app to complete the process. Methods to Check Points: Visit the office halls of traffic police departments in various districts and counties to check via touch-screen terminals. Alternatively, log in to the public service websites of municipal public security traffic management bureaus, locate the vehicle violation query section, enter the license plate number and vehicle engine number, and click to query. You can also call the information hotline or send a mobile text message to check violations. Conditions for Handling Traffic Violations via Internet Platforms: The violations must be recorded by traffic monitoring equipment, and the total points of pending violations plus the driver's current accumulated points must not exceed 12. Under these conditions, drivers can also self-handle point-free violations for non-personally owned vehicles or violations with points for registered vehicles that occurred after registration.
