You need to test the battery under load. With a multi-tester, or Auto Zone or Advance Auto will do this for free, test the battery voltage. It should have 12 volts. Then turn the key to the RUN position, it should stay at 12 volts. Then turn the key and see if the voltage drops when starting. If it drops significantley, more than.5 volts or even less, the battery needs to be replaced.
