if you are balancing them together as 1 battery, and they both have the same number of charges, but one hasn't been drained as long as the other, it will still work, but it will take a while for the balancer to get the batteries together, but if your balancer can't communicate with the charger (is not built in or does not have a data port) then it may not be able to get them together.
