Claim (Index 2):
The multi-voltage battery pack of  claim 1 , wherein:\n the second power tool interface of the single voltage battery pack is not mechanically coupleable with the second battery pack interface of the second power tool; the second power tool interface of the single voltage battery pack is not electrically coupleable with the second battery pack interface of the second power tool; the power tool interface comprises a slot in the housing; the slot is shaped and configured to mate with a downwardly extending projection of the second battery pack interface of the second power tool when power tool interface couples with the second battery pack interface of the second power tool; the power tool interface of the multi-voltage battery pack comprises a plurality of rails and grooves that are shaped and configured to selectively mechanically couple with (1) a complementarily shaped plurality of rails and grooves on the first battery pack interface, and (2) a complimentarily shaped plurality of rails and grooves on the second battery pack interface; the power tool interface of the multi-voltage battery pack comprises a latch that is shaped and configured to maintain a mechanical and electrical connection between the power tool interface and the first or second battery pack interfaces; the second power tool interface of the single voltage battery pack comprises a plurality of rails and grooves that are shaped and configured to couple with the complementarily shaped plurality of rails and grooves on the first battery pack interface; the battery cells of the first string comprise five battery cells that are arranged in a first row within the housing; the battery cells of the second string comprise five battery cells that are arranged in a second row within the housing; the second row is positioned on top of the first row; the battery cells of the first and second strings together are arranged in a 2\u00d75 matrix within the housing; the battery cells of the first string and battery cells of the second string each define respective longitudinal axes that are parallel to each other; the multi-voltage battery pack has first and second opposing lateral sides; each of the battery cells of the first and second strings has positive and negative voltage terminals; the positive voltage terminals of three of the five battery cells of the first string are disposed on the first lateral side of the battery pack; the positive voltage terminals of three of the five battery cells of the second string are disposed on the first lateral side of the battery pack; the negative voltage terminals of two of the five battery cells of the first string are disposed on the first lateral side of the battery pack; the negative voltage terminals of two of the five battery cells of the second string are disposed on the first lateral side of the battery pack; the negative voltage terminals of the cells within the first string on the first lateral side are vertically aligned with respective ones of the negative voltage terminals of the cells within the second string on the first lateral side; the positive voltage terminals of the cells within the first string on the first lateral side are vertically aligned with respective ones of the positive voltage terminals of the cells within the second string on the first lateral side; the power tool interface comprises a first electrical contact that is electrically connected to the first positive voltage terminal of the first string; the power tool interface comprises a second electrical contact that is electrically connected to the second negative voltage terminal of the second string; the first and second electrical contacts are shaped and configured such that coupling the power tool interface to the second battery pack interface causes the first and second electrical contacts to electrically connect to each other by way of an electrical jumper of the second power tool so as to cause the first and second strings to electrically connect to each other in series by way of the jumper when the power tool interface couples with the second battery pack interface; first operating voltage is between approximately 17 to 20 volts and the second operating voltage is between approximately 34 to 40 volts; the multi-voltage battery pack has an open circuit configuration in which the first and second strings are not electrically connected to each other in parallel or series; the power tool interface comprises a first row of electrical terminals that are shaped and configured to physically and electrically contact corresponding electrical contacts of the second power tool when the power tool interface is mechanically and electrically coupled with the second battery pack interface; the power tool interface comprises a second row of electrical terminals that are shaped and configured to physically and electrically contact corresponding electrical contacts of the second power tool when the power tool interface is mechanically and electrically coupled with the second battery pack interface; the first row is vertically offset from the second row; a plurality of the electrical terminals of the first row of electrical terminals comprise signal terminals; the electrical terminals of the second row of electrical terminals comprise first and second terminals; the first terminal of the second row is electrically connected to the first positive voltage terminal of the first string of battery cells; the second terminal of the second row is electrically connected to the second negative voltage terminal of the second string of battery cells;
