-My initial tests on a Arduino Mini Pro with radio module and motion detector shows a power consumption of 0.48 mAh in sleep mode. When motion is detected consumption raises to 1,5 mAh for a couple of seconds when radio powers up and transmits data to vera.
+My initial power measurements on a Arduino Mini Pro with radio module and motion detector shows a power consumption of '''0.48 mAh''' in sleep mode. When motion is detected consumption raises to 1,5 mAh for a couple of seconds when radio powers up and transmits data to vera.
 
-Converted to real life figures, this would make four 2000mAh alkaline AA batteries last for more than a year. Note this is in theory. I have not made any long time measurements. Read more about the subject on the following links.
+Converted to real life figures, this would make three 2000mAh alkaline AA batteries connected in series (giving 4.5V) last for almost '''6 months''' (2000/0.48 hours) directly connected to VCV (not raw as it passes a regulator). 
+Note that this is just a theoretical calculation. I have not made any long time measurements or tests myself yet. Read more about the subject on the following links:
