I've just swapped my Ring Doorbell 2 for a Ring Doorbell Plus. I'm wondering if I can use my old batteries from my Doorbell 2 in my Doorbell Plus, as I have two of them and I'd prefer not to have to buy new ones. Doorbell Plus battery info: Model No. 5F53E9, 3.6V, 5800MaH, 20.88Wh. 1INR19/662-2 Doorbell 2 batter info: Model No. V4, 3.65V, 6040mAh, 22.046Wh. 1ICR19/66-2 Is it safe to use my Doorbell 2 batteries in my Doorbell Plus? Many thanks.
