You need to code the battery module so it relearns the characteristics of the new battery, for example discharge rate. Currently your 8 may start switching things off needlessly because it thinks the battery is going to die faster than the new reality.

If the battery has the same AH and CCA then you usually just change the serial number slightly to fool it thinking it has a new battery.
