Hi. this is defiantly a slow or major drain that is occurring within this vehicle. Here is a test that you can preform that will help you find this battery drain so you can illuminate this issue.
--BATTERY DRAINAGE TEST PROCEDURE--
Using a 12-volt test light, hook one end to the negative battery post the other end to the negative battery cable you just disconnected. The test light will glow or "light" if there is a drain. If the "light or glow" is faint, that is probably normal draw for the clock or computer. If the "light or glow" is bright, then there is a large drain. That should be corrected. Now start removing and replacing the fuses one by one until the light goes out; that one will be the circuit with the drain. Remember to hold in the button in the door jam for the interior lights.
Please rate and god bless:)
