In the old days, the console clock could drain a battery in short order. You may also have a glove box or trunk light staying on.

There are several things that can run down a battery. The alternator not charging, bad or dirty connections from or to the alternator or battery, bad battery, an excessive draw on the battery from some source. How old is the battery? Did you do a load test on the battery after fully charging it? Have you done a milliamp draw test on the vehicle to see if you have something draining the battery. Depending on the vehicle and any aftermarket accessories added, there is always a certain amount of draw from the battery for things like clocks, radio memory, alarm systems, etc. Changing out parts without knowing the issue can waste lots of money and time. So I would check that the connection are clean and tight, verify that the charging system is charging, load test the battery, and perform a milliamp draw test. One of those is going to tell you what the issue is. If you need help with those test, you should ask someone here and locally for help before you start spending more money.

Disconnect the positive battery cable and clip a test light to the cable terminal and touch it to the positive post. If it lights, you have a draw. The clock usually isn’t enough of a draw to make the test light light up. If you have a draw, start pulling fuses. When the light goes out you will know which circuit it is on and can check all of the components on that circuit. If the light doesn’t light you will have to move on to a milliamp test to check for smaller draws. If your battery is charged and passes a load test it shouldn’t die that quickly from a small draw.

The clock won’t drain the battery until the points in the clock close and the solenoid winds the clock movement. In my case, the points fused together and burned the coil. You’ll smell the smoke when that happens.
