As long as your charger puts out more current than the self discharge rate of the battery (which is usually well less than 1 milliampere) and the open circuit voltage of the charger is greater than the voltage of the battery you are charging the battery will reach full charge if left on the charger long enough. It is a simple fact of physics.
