1. A method for monitoring and maintaining battery charge of a personal monitoring device, comprising:
locking the personal monitoring device to a limb of a monitored person, wherein the locking requires that the monitored person remain tethered to a power source for a period of time to charge a battery of the personal monitoring device;
collecting historical information about the personal monitoring device including movement data of the personal monitoring device and battery charging history of the personal monitoring device;
analyzing the collected historical information for patterns of battery charging behavior;
receiving a current location of the personal monitoring device;
first determining whether to send a battery charge reminder to the monitored person, based on at least a current location of the personal monitoring device, a current battery charge, and the patterns of battery charging behavior; and
providing, in response to a positive outcome of the determining, a notification to the monitored person to charge the battery;
wherein the first determining comprises:
second determining that the personal monitoring device is at a location where the patterns of battery charging behavior show a history of successfully battery charging; and
predicting that, absent additional charge, the battery charge will drop below a threshold level when the personal monitoring device is at a location where the patterns of battery charging behavior show lack of a history of successful battery charging at the location;
wherein the first determining considers characteristics of the monitored person relative to common characteristics or prior behavior of the monitored population, including how those common characteristics or prior behavior affect probabilities of potential battery violations, the characteristics includes prior criminal history and/or prior status as a parolee.
