1. A method of assembling a battery pack, the battery pack including an outer housing, a cell module including a module housing, a battery cell including a cell header, the battery cell having a nominal voltage of between about 3.4 V and about 4.2 V, the battery cell having a capacity of more than 2 Ah, and a terminal block including a terminal electrically connected to the battery cell and operable to connect the battery cell to an electrical device for power transfer, the method comprising:
assembling components of the cell module;
connecting the terminal block to the cell module, wherein the terminal block includes a female terminal having opposing contact surfaces operable to engage opposite faces of a mating male terminal of the electrical device;
applying a vapor-deposited coating to one or more components of the cell module and the terminal block, wherein, during applying, inhibiting application of vapor-deposited coating to the opposing contact surfaces via engagement of the opposing contact surfaces, wherein the opposing contact surfaces are in contact with each other during vapor-deposited coating; and
mounting the cell module relative to the outer housing.
