HI Joe.

The easy way to check what it might be is to measure the voltage of the battery using a multi meter the reading should be 12.8v then start the car to check if the alternature is charging the charging voltage should be 14.4v or higher if this is no lower than 13.8v then it's charging and your battery is not holding the charge.
