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 batteries and have to wait until they arrive.
NOTE: I ordered a Sanyo NiCd-Akku A 1.2 V 1700 mAh (Ø x H) 17 mm x 49.5 mm; this is not what originally is in there but as all NiCd batterys are 1.2v i think it should work. And this way i don't have to connect two 2/3A cells together and save some bucks too.
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)
