If you have access to a meter check the voltage before you try and start it, probably be sitting around 12v. Then check it again once its running to ensure you have around 14v, that will prove the alternator is working. If you have 14v while running your battery is not holding a charge.

If your alt is working it might be worth trying your battery on a trickle charge as if its very low your car prob wont charge it and just put enough power in for the car to run. Check the fluid too if ya can get in to the battery.

To be fair I had to have my battery replaced under warranty, 55 WRX, for the same issue not holding a charge.
