I know that all batteries have a set voltage. Do batteries than have a set amount of current would flow through them if connected to a circuit?

It depends on the battery, the internal resistance and the external (load) resistance.  Some batteries like NiMH, NiCd, LiPO etc. are capable of very large currents for a short period of time if you short them for example (which can result in a fire).  The current in a circuit is a function of the voltage and the total resistance of the circuit (which includes the internal resistance of the battery).
