Reasons Why the Battery Has Power But Fails to Ignite?

[DeClaire]

The battery has power but fails to ignite, possibly due to loose connections between the battery and the terminals, or it could be a damaged starter. Additional information about ignition failure is as follows: 1. The starter in a car generally does not experience many issues because each operation lasts only a few seconds, and the total working time in a year amounts to just a few hours. 2. The battery is a component that is more prone to failure. The battery is responsible for starting the engine. During engine startup, the starter needs to operate, the ignition system needs to function, and the fuel pump needs to work—all of which rely on electricity. The battery has two terminals, and a component on the wire connects to these terminals, enabling the battery to supply power to the car. If the connection between the battery and the terminals becomes loose, the battery cannot supply power to the entire vehicle.
