Charge controller does nothing of the sort. It charges until the battery hits 14.2V, holds that voltage until charge termination criteria are met, then it stops sending any current until the battery voltage drops to 13.5V. Once the battery drops to 13.5V, the charge controller will feed enough current to maintain 13.5V.
