Recommended 100%! Battery exchange my OralB Triumph Professional

I came by chance that you can let the battery exchange at its electric toothbrush. I was very annoyed namely, when after 3 years use of the battery of the electric toothbrush is no longer read and I recharge after every charge approximately 3 x could brush my teeth and then it was again empty. Since you pay 100 euros for such a thing and after 3 years as it gets.
I found the variant really great environmentally friendly with the battery exchange and it would make each time again. For now, the toothbrush works perfectly again, would almost say better than ever! Why should I, a new electric. Toothbrush for 100 euros to buy, when you can simply replace the battery. Think about the environment and do not become the throwaway!
I have the toothbrush posted (you get an instruction how to do it) and it was again repaired ratzfatz in my mailbox. Toll thing again any time!
