My cars battery is just fine but the car wont turn get any power unless i jump the car?

If you can jump start the car then the battery is not fine. Remove the battery cables and thoroughly clean them. If it still will not start check the voltage at the battery with the engine off. You should get 12.6 volts if the battery is fully charged. 12.4 it is 75%, 12.2 it is 50%, and 12.0 it is 25% charged. I would bet your battery is defective.
