This thesis presents the basic design of the system to test the voltage of a 1 volt underwater battery at a long distance by using a fiber optic system. This system contains the voltage-to- frequency converter which converts the voltage of the battery to a variable frequency pulse train, the optical transmitter, the fiber optic receiver, and a frequency-to-voltage converter which converts the variable frequency pulse train into an output voltage. This system has small error but if we use more precise components, we can get more exact result. Additionally, the life time of two kinds of batteries were measured by using this circuit.
