Question about Cars & Trucks
Not sure I follow your story.
Have you checked the output of the alternator while it is on the engine, and is it between 13 and 14 volts ? Does the battery lose power while the engine is running or after you turn the engine off ?
Is the alternator output normal but not reaching the battery ?

Several causes possible.
Carburattor or injection type?
Carburator >> auto choke faulty.
Carburator >> mixture very wrong adjusted
Drawning carburator (needle/floater)
Distributor weights cannot move (dirt/rust spring broken)
Very dirty airfilter, or clogged airfilter
Faulty ignition cap. Check contacts, especially middle one if oldfashioned and nonelectronical.
Ignition timing set incorrectly.
Fuel pump broken.
Fuel filter blocked almost.
Vacuum line damaged.
Exhaust internally clogged by loose plate (corrossion) (potato in tailpipe effect).
And very seldom, water or diesel.
And a list of a lot of other things.

Though your car seems fine without using the headlights, you have a charging problem, and need to get a couple things checked out. First make sure your battery connections are clean and tight. Your alternator belt should also be checked to make sure it is serviceable and properly tightened too. Your alternator should be checked under load, and lastly, your battery too. Most auto parts stores, such as auto zone,will check your parts for free,so you should only be spending money on what is broken!
