Human Factors; Procedure
I received CLR (Cargo Load Report) with motorized mobility aid - lithium ion battery aft cargo compartment circled with no aft cargo weight listed. I inquired the rampers and they said there was a mobility aid scooter in the back and they didn't know the weight or if the battery was still installed. The gate agent asked the passenger about the device and they said the lithium ion battery was installed and could not be removed. I reviewed the FOM dealing with mobility aid device batteries. I had the gate agent inform the passenger that battery would have to be removed from the mobility aid; and they would need to carry the battery with them under the seat in front of them. The passenger said the battery could not be removed; and that they could not travel without it. They decided to get off the flight. More training for rampers to recognize hazardous materials and to properly record cargo.
CRJ Captain reported HAZMAT procedure violation due to a mobility aid with a non removable lithium ion battery in aft cargo.
