Abstract: The present application provides a mounting base, a battery and a power consuming device, which relate to the technical field of batteries. The mounting base may be configured to be connected to an end plate and an output electrode, and an insulating structure may be provided on one side of the end plate and configured to insulate the end plate from a battery cell. The mounting base may include a main body provided with a flow guiding groove on the side facing the insulating structure. The flow guiding groove may be configured to prevent an electrical connection between the output electrode and the end plate by means of a liquid between the main body and the insulating structure.
