We flew into ZZZ with the understanding we were on a quick turn. There was a lot to do; making things hectic. I had to step off the airplane for a few minutes. When I returned; there was only about 15 minutes until departure. On my seat (Captain's) was a form notifying me of a lithium ion battery that would be on board and traveling with us. I then received the [cabin load] which notified me of a powered wheel chair in the cargo bin. The [cabin load] also noted that the battery had been removed. The battery was not listed as additional cargo on the [cabin load]. I understood that the two items were related and assumed that the battery was being carried in the cabin per our policy. That was my mistake. I never confirmed the location of the battery; and no ground personnel came up to speak to me about it. Enroute; I called back to the FA (Flight Attendant) and asked her if she noticed a battery that came on board. She had not. Upon arrival I went out to watch the bags come off the airplane. The powered wheel chair finally came off and sitting on the wheel chair in its own separate case was the battery. The battery was in its own hard black plastic case; made for travel. It also had a white baggage claim tag attached; as did the wheel chair. I should have slowed down; and asked the ground crew about the location of the battery. If I had known they had placed it in the cargo bin; I already knew that was not in line with company policy. The turn was a bit of a cluster; those times especially one needs to slow down and think about what they are doing.
We were running late due to cumulative delays forcing us into quick turns (24 min turns). We arrived in ZZZ; both the CA (Captain) and I needed to enter the terminal (FA (Fight Attendant) remained with aircraft). I returned to the gate and the GA (Gate Agent) says that now that a pilot was at the aircraft; she would begin boarding (this served to further reduce available time to get duties accomplished as we were distracted by late boarding on a quick turn). We accomplished our gate prep; pushed and departed. We had noticed a battery form that had been left on the CA's seat and assumed it was related to the mobility scooter that was loaded; but in our haste to meet performance standards; did not give it enough attention pre-departure. Enroute; we discovered that it was for a lithium battery that was removed from the scooter. We believed that this form may have indicated that the battery was removed for transport in the cabin (as we understand that our policies do not allow lithium batteries to be carried in the cargo hold). The CA called and asked the FA if she saw a battery brought on board; but she had not. Upon arrival the CA observed the removal of bags and discovered the case with the battery from the scooter had been with the scooter in the baggage compartment.I feel that there should have been better communication with ground handler that loaded the battery; not just a note tossed on the CA seat. However; we should have taken the time to verify the placement of the battery prior to push.
