A battery pack assembly or enclosure comprises one or more batteries having an electrochemical cell and an enclosure having at least an outer wall configured to create a sealed volume of space substantially around the batteries. An atmosphere of the volume of space comprises gas having a thermal conductivity less than 0.018 watts per meter per degree Celsius. This atmosphere of gas provides an insulative layer between the outer wall of the enclosure and the batteries. With this insulative layer, the battery pack assembly can be subjected to autoclaving without damaging the batteries. The battery pack assembly can be used to power surgical tools or other devices that are subjected to autoclaving.

An alkaline battery has a positive electrode mixture containing manganese dioxide and a conductive material filling a tubular positive electrode can that is closed at one end. A negative electrode mixture containing a zinc powder filling on an inner peripheral side of a separator is disposed on an inside of the positive electrode mixture. The negative electrode mixture contains zinc particles with a granularity of 75 μm or less at 25 to 40 mass %. The positive electrode mixture has a plurality of tubular pellets stacked inside the positive electrode can coaxially with the positive electrode can. A sum s of lengths of gaps between the pellets is set at 1 to 14% with respect to a sum d of lengths of the pellets. Thus, a sufficient amount of the electrolyte is held in the gaps and between the pellets in the positive electrode.
