Most of us like to have LIKE BATTERIES in the same banks as well as same age of batteries... This allows the converter/charger to match the battery internal resistance better with the hope that all of the batteries charge at the same rate when being charged.

Like said above give it a try and see if all batteries attain the 90% charge state at the same time.
