If the car battery dies after a few days of parking, it may be due to a battery leakage issue. Here are the potential hazards of leaving a car parked for too long: Tire Deformation: When a car is parked, the tires bear the full weight of the vehicle. Over time, this causes the contact areas of the tires to deform under pressure. The longer the car remains parked, the harder it is for the deformed parts of the tires to recover. In mild cases, this leads to uneven rolling radii, posing safety risks. In severe cases, the tires may become completely unusable. Oil Seal Aging: Extended parking can cause uneven stress distribution around the oil seals. Areas under higher stress may experience greater deformation, leading to permanent distortion of the seals and resulting in oil leaks. Battery Failure: The car's battery continues to discharge even when the vehicle is parked. Typically, the battery's capacity decreases by more than 1% per day due to self-discharge. Prolonged self-discharge can easily cause the battery to fail prematurely or become completely unusable. Engine Oil Oxidation and Deterioration: The longer a vehicle remains parked, the more severe the oxidation of the engine oil becomes. Oxidized oil loses its lubricating properties and can corrode engine components. When starting an engine that has been parked for a long time, the pistons and cylinders often experience dry or semi-dry friction, accelerating wear and tear on these parts. Electronic Component Failure: In vehicles parked for extended periods, electronic components and wiring connectors are highly susceptible to moisture and corrosion. The longer the parking duration, the higher the likelihood of malfunctions occurring.
