What is the reason when the battery has power but the car won't start?

The reasons why the battery has power but the car won't start: 1. Low voltage; 2. Malfunction in the ignition system or fuel supply system. If the car won't start, it is necessary to check the ignition system and fuel supply system. The main components of a car engine's ignition system include spark plugs and ignition coils. Spark plugs are wearable parts that require regular replacement. Just because the battery has power doesn't mean the car can start, because the starter is a high-power electrical device that demands very high voltage and current from the battery at the moment of operation. In contrast, the voltage and current required by ordinary electrical devices in the car are much smaller. Therefore, when most batteries are undercharged, it's not that they have no power left at all; their voltage and current can only meet the needs of low-power devices in the car but cannot drive the starter.
