The Battery is a device that first shows up in Assassin's Creed 3 inside the temple. It is a cube like power source used to power up the door and they are a necessary component to have before you are able to use the key. You gain the first Battery inside the temple that just happens to be next to the port it needs to be placed into. The second and third battery show up later in the game and requires Desmond to go out of the Temple and retrieve them himself but along the way he runs into Daniel Cross both times.
