1. The car will not start (or turn) if it sits for more than a day.
2. The battery has been replaced.

A bad Alternator can fail in such a way that it may Charge well enough to turn "off" the Alt Light/or read "Charge" on the gauge,,,
yet it will Drain the battery thru the Alternator's Diodes---"electrical one-way Check Valves"
Also,,a new Battery often needs a Full Charge put on it.
Many only have a Low Partial Charge.
Not too Likely ,,but possible.
Or,,as some of the other Good Folks have answered---your car has some device Draining it's battery,,,Trunk Light,,Engine Compartment light,,etc,etc,etc
They're Right,,,that is a common cause of Mystery Drain on Batts.
Good Luck with it!

Having just replaced the battery indicates that it is PROBABLY a good battery, but then you DO know that there are defective products on the market, right?
If the battery is known to be good, and the charging system is known to be within normal operational parameters (charge rate of > 14.3V @ idle), then the only thing left is what is termed a PARASITIC draw.
Something is causing a significant current draw from the battery when the car is just sitting.
Things to check…
1) Defective alarm or security system
2) Stereo or booster powered up with key off
3) Trunk or glove box light on (bad switches)
4) Defect in wiring causing some other device to be left on.
If you are going to attempt to repair it, connect a test light or meter to the system, and begin to remove the fuses, one at a time. Watch the light, and when you pull the fuse that controls the circuit that is causing the problem, the light will go out.
Happy Motoring

One of two things.
1. Something is draining power off the battery even when it's off.
2. The new battery is faulty.

process of elimination,first check the condition of the battery terminals. then
alternator check. then
fuses and fuseable links. There are automotive part stores that will check some if not all of these things out for you. Let your fingers do the walking and call around ie...Pep Boys, Kragen, AutoZone. etc.....

Have the charging system checked. Auto Zone or Kragen etc will check for free. also have the system checked with ignition off to see if you have a voltage drain. Will only take a minute.

you need a new alternator and voltage regulator and have the battery charged.

You have a dead short somewhere in the wiring.
