In 1923, Hannover visited Örnsköldsvik and Karlskrona in Sweden. She lost her role as flagship on 22 September, and the fleet was reorganized from North Sea and Baltic Sea commands to create the Battleship Division, to which Hannover was assigned. In mid-1924, the Battleship Division made its first major overseas cruise to Spain, and Hannover stopped in Portugalete from 6 to 13 July. Paul Behncke, the commander of the Reichsmarine, came aboard the ship during the autumn maneuvers in August and September, which concluded with a fleet review off Hel, Poland, on 10 September. While en route from Wilhelmshaven to Kiel in December, Hannover collided with a tugboat that had been torn from its moorings. Hannover was damaged in the accident and water flooded the engine room, forcing her to return to Wilhelmshaven for repairs that lasted until February 1925. The fleet cruised Norwegian waters during the summer cruise and visited Oslo and Ulvik, and in September the ships conducted training in the North Sea. On 1 October, Hannover once again became a flagship, this time for the 2nd Admiral of the Battleship Division, KzS und Kommodore Wilhelm Prentzel. At that time, the active German fleet consisted of Hannover, Braunschweig, the light cruiser Amazone, and II Torpedo-boat Flotilla.Hannover took part in several major cruises in 1926, the first of which, from 13 May to 18 June, went to Spain and the Mediterranean Sea. She visited the Spanish ports of Palma in Majorca, Cartagena, and Vigo during the cruise. The second cruise took place from 28 June to 1 July, and took the ship to Helsingfors, Finland. From 4 to 5 September, the fleet cruised in the Skagen, before beginning another Atlantic cruise on 11 October. During the voyage, Hannover stopped in Funchal, Las Palmas, Porto de Preia, Santa Cruz de la Palma, Villagarcia, and Amsterdam. The fleet returned to Germany on 16 December, and on 1 March 1927, Hannover was decommissioned for modernization and repairs, her place in the active fleet being taken by Schlesien. The ship received a new mast, but unlike her sisters kept her original three funnels. She was recommissioned on 25 January 1930 and rejoined the Battleship Division. She took part in the cruise to the Mediterranean that began on 2 April. She made stops in Vigo, Valencia, Messina, Athens, Argostolion, Palma de Mallorca, and Cádiz before arriving back in Wilhelmshaven on 18 June.Hannover took part in a large fleet parade in the Baltic on 20 May 1931 for President Paul von Hindenburg. She made her last trip abroad in June, when she visited Bergen, Norway. She participated in the autumn maneuvers that year, which concluded with a naval review for the outgoing fleet commander, VAdm Iwan Oldekop, on 11 September. During the maneuvers, Erich Raeder, the chief of the Reichsmarine, came aboard the ship. The ship thereafter went to Kiel, where she was decommissioned on 25 September. The ship was struck from the naval register in 1936, after which the navy intended to rebuild Hannover for use as a target ship. The conversion, however, never occurred. Instead, she was used in explosive tests. Ultimately, the ship was broken up between May 1944 and October 1946 in Bremerhaven. Her bell now resides in the Military History Museum of the Bundeswehr in Dresden.
