GO to auto zone or advance and have them run a check on your battery and alternator for free. Despite putting in a new alternator it may be a bad unit. You may have cooked a cell in your battery as well. Mine was draining dry slowly but it turned out to be of all things...the vanity mirrors staying on.

Sounds like you have a power draw from something in the car. Unhook your power cable from your battery, and clip on a test lamp between the battery post and the terminal you took off. If the light of the tester is on without the key on, then you have a power draw from in the car. If its on, then start pulling fuses one at a time till you see the light go out and that should narrow your search to which part of your car is causeing it.

also check to make sure that the battery light in fact comes on at startup. if the bulb is burned out that could cause a no charge condition. you should also check voltage with the car off 12v and on 14v

EZ way,do like snake said-take it to a parts store,let them check it-my guesse dead cell in battery-but they'll tell you for sure,then be happy to sell you one
