A battery for use with a surgical instrument comprising a battery dock, the battery comprising:
- (a) a battery housing;
- (b) at least one battery cell;
- and
- (c) a battery drain, wherein the battery is coupleable with the battery dock;
- wherein, in a first condition, the battery drain is not electrically coupled to the at least one battery cell,
- wherein, in a second condition, the battery drain is electrically coupled to the at least one battery cell to discharge the at least one battery cell, and
- wherein the battery drain is configured to transition from the first condition to the second condition as a result of the battery being coupled with the battery dock.
