Systems and methods for powering a measurement system are provided. In some aspects, a system includes a high energy density electric cell, storing energy for powering the measurement system; a rechargeable electric cell, being charged by the high energy density electric cell and providing high current bursts to the measurement system; and a charging control device, coupled between the high energy density electric cell and the rechargeable electric cell, and enabling the high energy density electric cell to charge the rechargeable electric cell. The high energy density electric cell operates at a current which allows the high energy density electric cell to be in its optimal zone of chemical efficiency.
