2000 stratus - trouble starting car

when I start my car, there is a ticking noise, then it stops. I can here it turning. It eventually starts but takes a while. Does anyone know what would be causing this. Is it the battery? Do you know where the battery is. But I don't see the battery anywhere. I just bought this car? Please Help.

hi the battery is located in the drivers side front wheel well there is a panel in front of the tyre .try to clean the terminals first. a dodge will not run with a loose battery terminal .later jj
