ABSTRACT:
Various apparatus and methods of supplying regulated battery power to an electrical device, such as a downhole tool, are provided. In one aspect, a method of providing power to an electrical device is provided that includes providing a plurality of batteries and providing a plurality of controllable regulators for regulating the power output of the plurality of batteries. The plurality of controllable regulators is set so that power is drawn from a minimum number of the plurality of batteries necessary to satisfy demand from the electrical device. The electrical device is enabled to periodically draw power from and thereby depassivate each of the plurality of batteries.
