The current flow will be the same but the original question was the current drawn from each battery. In other words, how quickly will it go flat? Assuming a pair of matched batteries in series and they will both go flat at the same rate as they are both having the same amount of current drawn from them, half of the total current required. Using the old water pump analogy, volts is pump pressure, amps is the quantity of water so the same quantity of water will be emptied from each battery and each will supply half of the amount needed by the load.
