1. A power pack for use with a surgical instrument, the power pack comprising:
a housing including at least one connector configured to facilitate attachment of the power pack to the surgical instrument;
a plurality of rechargeable battery cells located in the housing and configured to power the surgical instrument; and
an electronic control circuit located in the housing and configured to assess whether a subset of the plurality of rechargeable battery cells is damaged during a firing sequence of the surgical instrument and, in response to a determination that the subset of the plurality of rechargeable battery cells is damaged, step up an output voltage of the power pack to complete the firing sequence.
