Check the battery terminals and make sure they are both clean and do not have sulfation on them. Use a voltmeter and check how much volts the battery can produce. 12.45 volts is what the minimum spec for a 75% charged battery is according to ASE. If you want you can bring the battery to a car store to get load tested.
