Abstract: The present application relates to a battery, a method for manufacturing a battery, and a power consuming device. The battery includes at least two battery cells, wherein each of the battery cells includes electrode terminals arranged at end portions of two sides of the battery cell in a lengthwise direction, wherein a filling port for filling an electrolyte is provided in the electrode terminal on one side in the lengthwise direction of the battery cell, and the electrode terminals of the two battery cells are oppositely arranged in the lengthwise direction of the battery cells and are welded together to seal the filling ports. According to the battery of the present application, the filling port is provided in the electrode terminal, and the filling port does not occupy a space of an end cap, such that the size of the electrode terminal may be increased, thereby increasing the overcurrent area of the electrode terminal. Moreover, the entire battery is sealed directly by means of the electrode terminals without an additional sealing procedure, thereby reducing the cost and improving the production efficiency.
