Human Factors
During pushback the ground crew mentioned they were late pushing off the gate due to complications getting an electric wheelchair in the cargo compartment. When the load closeout came; I noticed that there wasn't an entry under the 'W/B' (wheelchair battery) row with a quantity or location. It was my understanding that a NOTAC (Notice to Captain) is not required; but that it would show up for crew awareness and weight and balance purposes on the load closeout. I brought it to the attention of the Captain a couple times that I thought it needed to be present; but he disagreed saying that it was only important that we knew it was there for smoke/fire purposes but wasn't needed on the closeout. At that point I deferred to Captains authority. We proceeded without further action.
A321 First Officer reported Captain elected to depart without required Hazmat documents for battery powered wheelchair cargo.
