HI,
While it is most likely the alternator, you need to check for secure connections to the battery as well as clean connections.
If ok, check the voltage at the battery with engine off. If under 9.5v, battery has bad cells and needs to be replaced.
If between 9.5v and 11v, charge the battery with a battery charger.
Anything under 12v, you need to start engine and check voltage at the battery with engine idling. If under 13.5v, replace the alternator.
