Answers :

This may take some time to figure out. More then likely there is a parasitic draw on the vehicle. What this means is something is using power when it shouldn't be. It could be a light,radio,window motor or any multitude of things drawing it down. Acceptable parasitic draw is about .015 amps depending on the model up to .025 amps. If possible disconnect the negative battery cable and install a test light between the negative cable and the negative battery terminal.If it lights up bright something is drawing on the battery. Under normal circumstances the light should be on but very dim.If the light is bright start pulling fuses one at a time till the light goes out or gets very dim. When it does go out or dim make note of which pulled fused caused it to go out.At this point you have a reference of which circuit is drawing on the battery. Once you know that then you will need to find out what components that circuit operates. Will be able to help you more once we know what circuit is dragging your battery down.
