What is claimed is: 1. A system of cordless tools comprising: a cordless power tool having a housing with a motor housing portion, a handle and a battery connection portion, the handle having a first end, which is coupled to the motor housing portion, and a second end that is coupled to the battery
What is claimed is: 1. A system of cordless tools comprising: a cordless power tool having a housing with a motor housing portion, a handle and a battery connection portion, the handle having a first end, which is coupled to the motor housing portion, and a second end that is coupled to the battery connection portion, the handle being disposed between the motor housing portion and the battery connection portion, the battery connection portion being spaced apart from the motor housing portion and having a pair of tool guide grooves, a pair of tool guide rails and a plurality of tool terminals; and a battery pack having a battery housing, a battery pack terminal block and a battery, the battery housing defining a cavity having a first chamber and a second chamber that are separated by a wall, the battery housing including a pair of battery guide rails and a pair of battery guide grooves, the battery pack terminal block housing a plurality of battery terminals and being received in the first chamber, the battery terminal being coupled to the battery and the battery being received in the second chamber; wherein the battery pack engages the battery connection portion such that the battery guide rails are received in the tool guide grooves and the tool guide rails are received in the battery guide grooves and wherein at least a portion of the tool terminals being electrically engaged with a corresponding portion of the battery terminals. 2. The system of claim 1, wherein the battery pack terminal block includes a recess for receiving a projection on the battery housing. 3. The system of claim 2, wherein the projection includes a first surface, which is generally perpendicular to the battery guide rails, and a second surface that diverges from the first surface with increasing distance from the second chamber. 4. The system of claim 1, wherein a portion of the battery housing that defines the second chamber has an upper housing segment, a lower housing segment and an intermediate housing segment located between the upper and lower housing segments, the intermediate housing segment being wider in a lateral direction that the upper and lower housing segments. 5. The system of claim 4, wherein the intermediate housing segment is longer in a direction parallel to the battery guide rails than the upper and lower housing segments. 6. The system of claim 5, wherein the intermediate housing segment is taller in a direction that is orthogonal to the lateral direction and the direction that is parallel to the battery guide rails than the upper and lower housing segments. 7. The system of claim 4, wherein the intermediate housing segment is taller in a direction that is orthogonal to the lateral direction and a direction that is parallel to the battery guide rails than the upper and lower housing segments. 8. The system of claim 1, wherein the battery terminals comprise male and female terminals. 9. The system of claim 8, wherein at least a portion of the male terminals are male blade terminals. 10. The system of claim 1, wherein at least a portion of one of the tool terminals and the battery terminals are male blade terminals and wherein the battery connection portion, the battery housing or both are configured to deflect the male blade terminals in a lateral direction. 11. The system of claim 10, wherein deflection of the male blade terminals is inelastic. 12. The system of claim 1, wherein one of the battery pack terminal block and the battery housing includes a plurality of laterally extending grooves and wherein the other one of the battery pack terminal block and the battery housing includes a plurality of bosses that are received into the grooves. 13. The system of claim 1, wherein a portion of the battery terminals are configured to transmit data about the battery pack. 14. The system of claim 1, wherein the battery comprises a plurality of battery cells that are oriented longitudinally in a direction that is parallel to the battery guide rails. 15. The system of claim 1, wherein the battery pack terminal block includes a main body that defines a laterally extending step that is disposed parallel to a portion of the battery housing through which the battery pack terminal block extends. 16. A method of forming a system of cordless power tools comprising: providing a battery; providing a terminal block with a main body and a plurality of battery terminals; electrically coupling the battery terminals to the battery; slidably inserting the terminal block into a first recess in a first battery housing shell and the battery in a second recess in the first battery housing shell; and coupling a second battery housing shell to the first battery housing shell to retain the terminal block and the battery therebetween; wherein the electrical coupling between the battery terminals and the battery is the sole physical connection between the terminal block and the battery before the terminal block and the battery are received in the first battery housing shell.
