Wiring Mechanical Chime...will battery charger still work?

Hi: when the Ring 2 is connected to a transformer for the purpose of powering a mechanical door chime, will the transformer still recharge the Ring's battery? Or is it a case of either the transformer is acting as a supply to the Ring's battery charger OR it is activating a mechanical chime, but not both? (I have seen the wiring diagram that shows a transformer between a Ring and two mechanical/remote chimes and I understand that. Just not sure if wiring it that way will maintain the trickle-charge to the battery) tks
