You have an off draw problem.Check to see if you have a glove box light staying on, or one in the trunk not going out when the trunk is closed. If not, take one battery cable off the battery post and connect a test light between the cable and the battery post. It should lite up. then start removing the fuses one at a time until the light goes out. when it dose,look and see what the fuse is goes to. this will be what is causing the problem.

You could need a regulator. Some of the older cars need to have the regulator adjusted when you change the battery and /or alternator. Just replacing the voltage regulator may fix it. If not, then you need to adjust it so it maintains the voltage in the specified range.
Also any metal touching the battery will drain it !..and check to see if any small lights are on....such as the under hood light. If you can't tell if it goes off when you close the hood, then just pull the bulb.

If you have an amp-meter, connect it between the negative battery and the negative post of the battery. Make sure the meter is set to the highest setting (10A). Observe the current flow with ignition OFF. Next start removing the fuses one by one until there is no drain on the battery. Now, search the circuits that are connected to that fuse.

Chek the battery. You could have a bad cell. Also, recheck the alternator, and make sure it is giving a good charge at idle, and a strong enough charge when you are driving. I had a problem like this and they told me my alternator was fine, but when they put a load on it, it was not giving a great charge. Of course it could be your volt regulator also, make sure you check that. You could also check the computer, and make sure it is sending the proper signals to the equipment nd make sure it is not giving you false readings on the charge or the system.

Yes, the regulator could very well be bad. It turns the alternator on and off by putting 12 volts on the field coil. It could be that it isn't coming on often enough.

on older cars , my buddy runs a starter alternate service and he all ways recommends that you change the voltage regulator with every rebuilt or new alt. he the expert!

It could be some device that is frawing current while the ignition is off, like a remote starter.

Check your after market stereo.
