Hello,
It sounds like your vehicle have excessive parasitic draw (current drain).
A parasitic draw is the current drain that happens in a electrical circuit with a battery.
There is always a minimum amount of draw that is acceptable.
However due to any faulty electrical component the parasitic draw cab become excessive, like a shorted out window switch or a light staying on.
