Introdução

Electric toothbrushes are powered by a rechargeable battery, that enables the reciprocating brushing motion of the bristles. If your electric toothbrush loses power quickly or doesn't hold charge, most likely the rechargeable battery needs to be replaced.

    You can use the hole in the bottom of the charging base (underside) that the top fits into and catches. Just twist gentilly back and forth until it loosens, then pull up with your fingers or pliers. Note, this is not like the Braun sonic care where the bottom comes off… should Have looked at the guides first as a I cracked the bottom trying to twist off the bottom like that brush.

    Die weiße Kappe kann nicht einfach nur abgezogen werden. Sie muss nach links gedreht werden!

    I saw on a Youtube video you can use the center hole of the charging base instead of pliers. It fits perfectly on mine.

    I am hoping the author of his guide receives theses comments. I have a Braun brush with dud battery, and am hoping to replace. I am afraid it is not at all clear from the photographs which are the points that need de-soldering. Thanks for any help.

    Having now noticed and browsed the guide history, I see that there were indicators for where to desolder (on one photo only). I can’t understand why these clarifying marks were then removed from the final draft?!?!?!

    Peter Bull - Responder

    IFixit technical team advised us to remove the indicators on the photo before we could publish it .

    How do I contact the technical team to complain about their censoring of indicators. Bonkers!

    Unless you are extremely skilled at soldering I advise against attempting to do this battery replacement. I had two brushes with rapidly discharging batteries. After the first one failed to work with replacement battery, I tried on the second, only to discover that, by the time the solder had heated enough to liquify and remove, the fine circuits on the circuit board had fried and the brush was useless. (And I have done my fair share of soldering)

    • Ensure you recharge the toothbrush after the repair. Even if the replacement battery is already fully charged, the toothbrush will fail to power on if you don’t recharge the toothbrush.

To reassemble your device, follow these instructions in reverse order. Remember to apply just enough solder to re-attach the terminals.

This is very easy to do. I had no problems following your instructions.

Thanks.

Is this a regular rechargeable AA?

Thanks again.
