Correct.
Registering the battery is erasing computer adaptation. Once new battery is installed the computer will evaluate it's behaviour for a few cycles and then will charge it according to the programmed data (battery type and capacity,i.e Ah) and the adaptation data. Later in the life of the battery it may keep 15v or more in order to keep the battery in the highest [possible] charge state.
