If the suspension is continually settling whilst parked then there's a leak somewhere but levelling downwards does not consume much power, only enough to open the corner air valves occasionally. Maintaining height with the engine running uses the compressor but if the voltage is too low then no height increases will be allowed, not the lowered safe mode which is triggered by a fault generated by the ABS ecu, eg the HDC fault. HDC requires some other systems (eg gbox and TC as Sniegy suggested) to be fully functional so any fault in those will disable HDC.
You need to see what fault codes are being stored. It may indeed be caused by a failing battery but not due to the suspension levelling.
