  3. Locate the battery plug and squeeze the clip on the face of the battery plug to release the plug from the socket, and then unplug the battery cable from the socket.
  4. Push the blue locking tab on the battery holder, so that the latch releases from the holder.
  5. Slide the battery down the riser bracket, lift the battery out of the controller, and then set it aside.
  6. Slide the replacement battery pack down along the sheet metal side wall until the support tabs on the side wall hook into the slots on the battery pack, and the battery pack latch engages and locks into place.
  7. Plug the battery plug into the riser socket and make sure that the plug locks into place.
