Why does the car battery die after being parked for a few days?
1 Answers
If the car battery dies after being parked for a few days, it may be due to a battery leakage issue. Below are the hazards of leaving a car parked for too long: 1. Tire deformation: When a car is parked, the tires bear the entire weight of the vehicle, which over time causes deformation in the contact area. The longer the car is parked, the harder it is for the deformed part of the tire to recover. In mild cases, this leads to uneven rolling radius, posing safety risks, while in severe cases, the tire may be completely ruined. 2. Oil seal aging: Prolonged parking can cause uneven stress distribution around the oil seal, leading to permanent deformation and oil leakage. 3. Battery failure: The car battery discharges even when the vehicle is parked. Generally, the battery capacity decreases by more than 1% per day. Long-term self-discharge can easily cause the battery to fail prematurely or completely. 4. Engine oil oxidation: The longer the car is parked, the more severe the oxidation of the engine oil. Oxidized oil loses its lubricating properties and can corrode engine components. When starting a long-parked car, the cylinder and piston may experience dry or semi-dry friction, accelerating wear. 5. Electronic component failure: Prolonged parking increases the likelihood of moisture and corrosion in electronic components or wiring connectors, raising the risk of malfunctions.
