#OralB #Pulsonic started the second time in its lifetime to erratically stop during use.

First time I fixed it by reattaching the battery which is soldered directly to the pcb on one side.

This connection is the breaking point of the product: it is not designed to withstand vibrations or falls.

This time I additionally soldered a small wire from the battery to the connection point on the pcb - hoping the cables flexibility will withstand vibrations and falls.
