Leaving a car unused for a month will not cause the battery to die, but it is best to disconnect the positive and negative terminals to avoid natural power drain. Poor vehicle condition: For cars in poor condition, the battery may lose power in about a week. However, there is no need to worry too much. Simply driving normally for one to two hours can restore the battery to its normal charge level. If the situation is severe enough that the engine cannot be started, a jump start may be required to activate it. For vehicles parked for extended periods, it is advisable to start and drive them at least once a week if possible. Recommendations: If you are usually busy with work, consider driving the vehicle on weekends for a few dozen kilometers. This can help recharge the battery, evenly distribute tire pressure, and most importantly, allow the engine oil to better adhere to the internal parts of the engine, which is crucial for vehicle maintenance. Keeping the engine running smoothly is also an effective method of self-maintenance for the vehicle.

I remember once my car sat unused for a whole month and ended up completely dead, couldn't even open the doors. This happens because a car battery is like a phone battery - it slowly discharges on its own. Even when doing nothing, it loses power. Those alarm systems, clocks, and computer modules in your car are all quietly draining electricity, which we call parasitic loads. Combined, they can drain a battery in just one month. Modern cars with more electronics are even more prone to this issue. Now whenever I travel for work, I either ask my neighbor to start the car and let it run for ten minutes weekly, or simply disconnect the negative battery terminal. Otherwise, you're not just looking at battery repair costs, but also unnecessary hassle and delays. It's slightly better in summer - winter accelerates self-discharge, and high humidity affects it too. My advice: make it a habit to avoid long-term parking.

Will Cars Parked Outside in Northeastern Winter Get Damaged by Freezing?

Winter vehicles parked outside will not get damaged by freezing, but due to the low temperatures in winter, car malfunctions often occur. Common cold-weather car issues include the following: Dead Battery: In low winter temperatures, the electrolyte activity in car batteries is relatively low, resulting in poorer energy storage capacity. This is especially critical for electric vehicles—always check the battery level. Remember to turn off air conditioning, headlights, and other electrical equipment after shutting off the engine to avoid battery drain and getting stranded in the cold. Starting Difficulties: Winter often brings engine starting issues. Aside from a weak battery, carbon buildup in the engine's intake system may also be the culprit. It's recommended to clean the throttle valve before winter to reduce such occurrences. Additionally, engine oil becomes thicker in winter, increasing resistance and making the engine harder to start. Switching to a thinner viscosity oil can help alleviate this issue.

Does the clunking sound during emergency braking damage the car?

Emergency braking followed by a clunking sound is the effect of ABS activation and does not harm the car. How ABS works: The clunking sound during emergency braking is most likely caused by the activation of ABS. The working process of ABS is actually a cycle of locking-releasing-locking-releasing, keeping the vehicle in a state of near-lock intermittent rolling. Therefore, when you slam on the brakes and trigger ABS, it produces a clunking sound, which is normal. In this situation, you should press the brake pedal firmly all the way. The principle of ABS: The principle of ABS is that during braking, based on the speed signals from each wheel speed sensor, ABS quickly determines if a wheel is locking up. It then closes the normally open input solenoid valve for the wheel that is starting to lock, maintaining the braking force. If the wheel continues to lock, it opens the normally closed output solenoid valve, preventing the wheel from fully locking due to excessive braking force.

Does Filling Up Until the Pump Clicks Mean the Tank is Full?

Filling up until the pump clicks does not mean the tank is fully filled. Reasons why it's not full: Gas stations use self-sealing nozzles, and stopping when the pump clicks does not actually mean the tank is full. The upper part of the fuel tank reserves some space for fuel vapors to prevent excessive internal pressure. After the pump clicks, if the attendant tries to round up the amount but the difference is still significant, it's best not to add more. At this point, the actual fuel volume is far from the indicated amount, which not only wastes money but can also lead to overfilling the tank, causing serious issues. Hazards of truly overfilling the tank: Risk of spontaneous combustion: A full tank increases the likelihood of gasoline leakage, which can easily lead to a fire. Fuel tank blockage: Excessive pressure in the tank can disrupt fuel supply and, in severe cases, prevent the car from starting. Charcoal canister damage: The charcoal canister absorbs fuel vapors, but if the tank is overfilled, liquid gasoline can enter the canister, damaging it. Gasoline entering the cabin: Prolonged exposure to gasoline fumes can be harmful and, in severe cases, carcinogenic.
