Good to know

Bosch: 'All frame batteries of the smart system use the same mount' - you can insert another one 'provided the geometry of the eBike allows it'. Larger packs (725/800 Wh) are physically bigger, so frame clearance can rule them out.
Not interchangeable with Bosch eBike System 2 PowerPacks, even those with the same Wh number (e.g. PowerPack 400/500 System 2).
Bosch: 'Use only original Bosch batteries that the manufacturer has approved for your eBike' and 'Only charge the battery using original Bosch chargers'; Bosch warns other batteries/chargers can be a fire hazard (Bosch PowerTube 750 operating instructions, as hosted on ManualsLib).
Only fits bikes whose rear rack is built for the smart-system PowerPack Rack; Bosch's page does not state that every rack takes both the 400 and 500 Rack, so confirm with the bike maker or dealer.
Not interchangeable with frame PowerPacks or with System 2 rack PowerPacks.
PowerTubes are built into the down tube and the frame is designed for one length: Bosch lists smart-system PowerTube 500 at 345 mm, 625 at 415 mm and 750 at 484 mm long. A different capacity only fits if the bike maker approves it for that frame.
