Find a volt meter, check the battery voltage with the engine stopped, it should be a around 12 V. Now start the engine and the voltage should be around 13.5 V. If the alternator isn't putting out about 13.5 (+/- .5 V) the replacment alternator could be bad or you might have a bad connection somewhere.

Why does the battery light on a 2002 Civic LX come on when started goes out at exactly 4000RPMs and then will come back on at 2500 RPM even after the battery was replaced?
This is not a battery problem. Your charging system, the alternator, is not putting out enough juice to charge the battery until you reach 4000 rpm. Have the alternator and charging system checked.

What does it mean if your car battery light stays on even after you replaced it?
means your battery isn't being charged by the alternator. What originally seemed like a flat battery being the problem, would more than likely be the alternator at fault, which will drain the battery, not keep it charging on the move, hence, battery light displayed on your dash. Before jumping to the spares shop, check all the connecting wiring between these components, in case of any loose connections
