Does wiring batteries in series increase the watt hour capacity of the batteries?

i know it doesn't change the amp/hr capacity but does it increase the overall wattage compared to the batteries individually,
10x 3.6v batteries at 19amp/hr= 684w/h, does 12v series circuit at 190amp/hr=2280w/h

I've wondered about this for a while and couldn't find the answer anywhere.
