Can the batteries stay on charge until needed, or will they over charge?
Hi @BGO. The Ring Rechargeable Batteries are meant to be plugged in and left charging for 8 hours in order to get a full charge. When you first plug in the battery, it will have an orange and a green light, meaning it’s charging. Once the light is green, it means it’s fully charged and will no longer charge up anymore. From there you can use it on any of your Doorbell or Cameras and be good to go!
