    Make sure the battery terminals are clean and tight. If you have a voltmeter, check the alternator output. Voltage at the battery should be 12.6 with engine off and at least 1 volt higher with engine running. If those check out to your satisfaction then you will need access to some diagnostic equipment to check alternator amperage output.
