A bit wrong, mostly right. The electromotive force (the voltage at open circuit) at full charge will depend only on the type of cell - the materials it's made from and so should be the same. however, the internal resistance will affect the amount of useful energy (and terminal voltage) you can get from the cell as soon as you start to draw a circuit current. Most cells in batteries are all made in the same process and should have practically identical internal resistance if they have the same specific gravity electrolyte. BTW -You will deliver the maximum useable energy from a cell when the load resistance is equal to the internal resistance. One of the important things about a lead/acid battery is that the internal resistance is so low that very large currents can flow at short circuit (or near) so they are really useful for cranking loads.
