Braun is the manufacturer of a myriad of hand-held personal care devices, such as the battery-operated toothbrush model 4731. The Braun battery-operated toothbrush model 4731 is powered by a AA battery. The battery is located inside the main body of the toothbrush in a special battery compartment.

  2. Locate the seam toward the bottom where the battery compartment screws into the handle.
  3. Grasp the battery compartment and twist it counterclockwise to open it.
  4. Remove the old battery, noting how it is positioned in regard to the positive and negative terminals. Dispose of the old battery.
  5. Insert the new battery into the battery compartment the same way the old one was positioned. Reattach the battery compartment by twisting it clockwise to tighten it.
