Repair guides and support for battery-powered toothbrushes.
I would like to replace the battery on my electric tooth brush - Oral B Triumph. I am told that the battery is soldered to the circuit board.
Siva, yes it is. Here and on Here as well can you get some decent videos. Once you open it up, you should easily find the number for a replacement battery. Something like this should fit. Hope this helps, good luck.
