What are the reasons why the car always has no power and cannot start?

Under normal circumstances, a vehicle can be parked for up to one week. If the car frequently has no power and cannot start, the primary task is to check whether there is an issue with the battery quality or if its performance has degraded, necessitating the replacement of a new battery. Secondly, the vehicle may have an electrical leak, requiring the identification of the leaking component and checking if additional electrical devices have been installed. Methods for maintaining a car battery: 1. Avoid long-term parking in open parking lots: If parking for an extended period, the battery should be removed and taken away to prevent freezing damage. 2. Pay attention to the starting time: The car engine is harder to start in winter. Each attempt to start the car should not exceed 5 seconds, with a minimum interval of 15 seconds between attempts. If the car still does not start after several attempts, check other aspects such as the circuit, ignition coil, or fuel system. Avoid multiple uninterrupted attempts to start, as this can cause the battery to over-discharge and burn out. 3. Regularly charge the car battery: A battery left unused for a long time will gradually self-discharge until it becomes unusable. Therefore, the car should be started periodically to charge the battery. 4. Clean the terminals regularly: The battery terminals should be cleaned periodically and coated with special grease to protect the wiring harness. Regularly inspect the battery accessories and connecting lines. 5. Avoid using car electrical appliances after the engine is turned off: Using the battery alone when the engine is not generating power can cause damage to it.
