Hi,
Have you specified a Physical / vRay camera for each view in the Batch render dialogue?
If you don't use a Physical / vRay camera and choose an orthographic or perspective view (or the default 'viewport') instead, the exposure will be all wrong. The exposure in vRay comes from the camera, and if viewed outside the camera lens the exposure control will not affect the scene.
