Welcome to the forum. I'd have to check the charging system. With everything turned off, use digital multimeter across battery posts, the generic spec for a full charge is 12.6 volts. Then start the vehicle, take a second reading across battery posts. the second reading should be higher than the first, if the charging system is working.
Another possibility is a battery drain, with everything turned off. Usually, you check amp draw, with everything turned off. If the specs exceed normal, there is a problem. The older way to do it, is to use a test lite. You take battery cable loose, connect the testlite between battery cable and battery post. If lite comes and stays on, there is a drain. You pull fuses one at a time, when you pull the fuse on the problem circuit, the lite goes out.
