Title
Repairing Braun Oral-B Sonic complete electric toothbrush Battery
Introduction
The battery of my toothbrush died and i have to replace it cause its a shame to throw away a electronic device just because the battery is death. I already opened it to see what kind of battery sits in there.
Now i ordered some replacement NiCd batteries and have to wait until they arrive. Probably NiMH batteries could be used too, at least they have same voltage but there might be some problems with the charger cause NiMH batteries can explode if overcharged.
NOTE: There are some very thin wires inside the toothbrush and you may destroy your device while "Repairing" it. But who cares if the manufacturer says your only option with a death battery is to bring the device to a recycling facility.
NOTE: Check your local regulations for recycling toxic waste (NiCd-Batterys)
