I'm seventeen years old and have my first car... driving it for a while, needed a new battery. My parents just divorced two weeks ago so my dad lives quite a bit away but he bought me a new battery and came over and just installed iit. When I went to start the car it just made a weird clicking noise... its standard so I roll-started it and he told me to leave the car running for half an hour to charge the battery. Now he is gone and I am alone with a running car and I wanna make sure that it will start when I turn the car off... anyone know if his assumption is right??
