Braun/Oral B electric tootbrush.
I have a Braun/Oral B electric toothbrush that is slowly fading out. At
first, the green l.e.d. charging light would barely light even though it would still charge. Then, a few days later, the two minute timer that interrupts the motor stopped working. Finally, the motor speed has dropped noticeably and will not even run for two minutes. I'm trying to figure out how to disassemble this thing and maybe replace the batteries. It's approximately ten years old. Here is a picture of the bottom casing. http://www.pbase.com/image/89365774 I've poked and prodded but can't seem to get this thing apart without chipping the plastic. If anyone has been down this road before I'd like to know how to change the batteries. Thanks for your reply. -- David Farber David Farber's Service Center L.A., CA |

I'm not positive it was a Braun, but the last one I got apart I did by pushing the handle onto the charging base and turning it 90 degrees. -- Angry American flags attack Hillary Clinton! |

The Braun's I've had don't seem to be designed for battery replacement.
Some of the charger stands have pins and flanges for the purpose of ripping open the toothbrush to remove the cells for recharging. Whether you can successfully reassemble the brush is another matter. I've never tried. |

This one is obviously not the same as mine, but within the charging 'cradle' (which was keyed) you could twist the body so the bottom would come loose. If yours is not keyed, you need to find a way to hold onto the bottom section while separately holding onto the body and twisting about 90 degrees. Once loose, the bottom would pull out and reveal the guts. The battery was encased in a plastic "cage", and not a "user serviceable" part, but if you're careful about it, it can be done. Although the battery (NiCd in my day) was not a "normal" size, we did have an electronics outlet here in Australia that sold similar batteries. So if you look, you should be able to find them around your neck of the woods. -- Linux Registered User # 302622 http://counter.li.org |

It took quite a bit of effort for an experienced disassembler such as myself to get to the insides. Not only that, the battery pack is soldered to the circuit board. Perhaps the latest generation of toothbrushes are more recyclable friendly. On the other hand, you have to seal the mechanism and electronics from moisture so I doubt it will ever be as easy as removing a cell phone battery. -- David Farber David Farber's Service Center L.A., CA |

Considering that the point of tightly sealing them is to force you to buy a new toothbrush when the battery fails, it's amazing that any water got in at all. |

Fix the charger unit to the underside of a shelf and make some sort of carrier or sprung/elastic plus clip, for the motor unit to be held vertically upside down under the charger "base". Goo will always find its way past what may initially be a seal around the rotating shaft down into the works, unless you park it upside down. The makers want to sell more units. -- Diverse Devices, Southampton, England electronic hints and repair briefs , schematics/manuals list on http://home.graffiti.net/diverse:graffiti.net/ |

Per Heinz Schmitz:
The manual of my Philips Sonicare says, that the battery is "not to be replaced", but on failing the whole unit should be dumped. When I discovered that, I decided, never to buy a Philips device again. I went through one rechargeable electric toothbrush and learned my lesson. Now I use the most el-cheapo Braun that has the circular brush and takes two AA batteries - that last a looooong time. I think a pack of three replacement brushes costs more than the entire device - with one brush on it - does. I don't do it, but one can always opt to use rechargeables.... -- PeteCresswell |

is "not to be replaced", but on failing the whole unit should be dumped. When I discovered that, I decided, never to buy a Philips device again. But this is true of all the rechargeable toothbrushes. The Sonicare probably does a better job than the cheap Braun, but I'd be reluctant to claim that as fact. |

I have one of the older ones with the built in battery, it's been going strong for about 8 years now, my dentist recommended it and I've been very happy with it. My mom gave me an older one with a failed battery, I've been meaning to crack it open with the bench vise and see if I can replace the battery, the thing ought to work well for cleaning small parts. |

I've just started on my third _pair_ of Sonicares, and find they last 3 to 3.5 years. You are fortunate to have yours last 8 years. You are welcome to my last two for the cost of postage. |

I wonder if you can get a new rubber washer/seal kit for this brush. lol I have two of those, one without a charge light. I was under the impression those things were pretty much water tight. I've had three of them apart and have not observed any moisture inside; others have found toothpaste getting into the top bushing and binding the shaft. Some of the units (in my case, the older ones) use two 2/3A batteries (e.g. Sanyo KR600AE), others a single AA. I replaced an AA cell with a high-capacity NiMH, and the first charge lasted a month (used two minutes per day). TM |
