While it is quite place for an extended battery with higher performance, it is questionable whether even then only the
Charging electronics so clearly comes. On the net I could not find anything in this regard.
I have then ordered this battery which surely where is also different cheaper to have and then
perhaps with longer solder tails, but currently it should go quickly.
Anyway, tidy it needs reworking to the solder tails, or even an extension of the positive pole.
Thus, experience in such work certainly helpful.
Otherwise, I can not write much more to it. Disassembly or assembly of the toothbrush is best explained in the network.
For me, the toothbrush holding again 12 days with 2x2min brushing by.
How long the battery still works now show up.
Thus, for the time being, from me 5 stars.
