In a commercial version of the RTrak I am working on for an overseas customer, we are using two 9V batteries in series. This gives the internal switching regulator plenty of "food" for a long run. One bench test gave us about 5 hours.
Of course, keep in mind that is using a stripped down version of the SMT OpenTracker 1+, not a Tracker2.
