### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Cheapest way to rebuild toothbrush battery pack
  

*by T***Y on Reviewed in the United States on April 5, 2024*

Solder two of the lugs together and the wires from the toothbrush.  Since the tabs are already welded to the battery they won't overheat from soldering.  Batteries Plus charges almost $15 to take the same two cells, add the tabs and solder them together.
