Abstract: A battery and an electric apparatus are described. The battery includes a firefighting pipe and a plurality of battery cells provided with a pressure relief mechanism. The pressure relief mechanism is configured to be actuated and release internal pressure in a first direction when the internal pressure or temperature of the battery cell reaches a threshold; the firefighting pipe is arranged on a side of the plurality of battery cells that is provided with the pressure relief mechanism, and is disposed in a staggered manner with the pressure relief mechanism; and the firefighting pipe is provided with a drainage opening, where the drainage opening is configured to discharge a firefighting medium toward the pressure relief mechanism when the pressure relief mechanism is actuated, so as to cool the battery cell. The battery allows the firefighting medium to more quickly cool a battery cell, thereby improving safety of the battery.
