First, make sure when the "NEW" battery was installed, the battery terminals were tight. Next, recharge the battery so you can start the car. When you do this, use a volt gauge and check the battery. You should see 12v (aprox). Next, start the engine and recheck the battery. You should see 14+v. If you don't, have the alt rechecked. If it shows good, chances are the fuseable link between the alt and battery is bad and not allowing power to flow from the alt to the battery.
Let me know if you have other questions.
