In this video I explain how to open an OralB toothbrush in order to change a damaged battery for a rechargeable AAA type battery, for a much cheaper price than the original battery. The voltage of the battery measurement was 1.4V, instead of what I say in the video of 2.4V. I made the video at the suggestion of a coworker, as he told me that there was no video in Spanish that explained well how to open the brush and do the repair correctly. 3D printer files to make the adapter rings: STL file: https://drive.google.com/open?id=1PQ_...
