When you turn the key in your ignition, your car battery sends a surge of power to the starter motor. The starter motor then engages with the flywheel on the engine and turns it over. This process requires a lot of power, and it can put a strain on your battery. If your battery is old or weak, it may not be able to provide enough power to start the engine. This is why it's important to keep your battery in good condition and to replace it when it starts to show signs of weakness.
