Leisure Battery or Vehicle

Can somebody tell me how my alarm and tracker on the Bourton is powered? I presume the alarm is linked to the vehicle battery.
 Is the tracker power coming from the leisure battery?
With nothing else on and no EHU I only get 1 day from the leisure battery if it is powering the tracker. 
Is the tracker that hungry or do I need a new battery?
Thanks

If you have the Hal Locate tracker, which is what is fitted to our Bourton, it is powered from the vehicle battery. If it is powered from your leisure battery, It’s power consumption is described as being “ Ultra low “, although I’m not sure what that means or what it’s power consumption is.
