Solar Controller settings

A recent thread on Solar panels saw me check the settings on my PL20 controller.

All was correct, except that it was set for a 120ah battery whereas recently a new 105ah has been fitted.

As the PL20 jumps from 100ah to 120ah as the available choices my question is what to set the controller to?

Set at 100ah the controller will be undercharging the battery but at 120ah will be overcharging.

Is the difference too small to be an issue?
