If the battery in your Braun Oral B electric toothbrush has stopped working, many people will tell you that you have no choice but to throw the entire toothbrush away and replace it with a new one. Even the Braun Oral B website insists that the rechargeable battery in your toothbrush cannot be replaced. Despite what you've heard to the contrary, the battery in your Oral B electric toothbrush can be replaced. The first thing you'll need to do when replacing your electric toothbrush battery is to get your toothbrush open to access the battery. While this is more difficult than it sounds, it is by no means impossible.

Tightly grip the notches on the bottom of your Braun Oral B electric toothbrush with a pair of needle-nose pliers.

Twist the pliers 45 degrees to the left to unlock the electric toothbrush's bottom cover.

Pull the housing of your Braun Oral B toothbrush away from the bottom cover to reveal the internal components.

Note the two small wires attached to the circuit board of your electric toothbrush. Place a piece of desoldering braid over the soldering points and touch the braid with the tip of a hot soldering iron to free the wires.

Remove the bottom piece from the internal components of your electric toothbrush by applying pressure to the two clips that hold the piece in place. Set the piece aside until you are ready to reassemble your Braun Oral B.

Examine the circuit board in your Braun Oral B electric toothbrush to locate the two soldering points that hold the circuit board in place. Use the desoldering braid and a hot soldering iron to remove the soldering points on both ends of the circuit board.

Remove the circuit board to reveal the rechargeable nickel cadmium battery.
