About $5, you will think that the battery in the Oral B pulse toothbrush will last longer.
How did I overcome this problem.
These are the tools I have used.
One pair of auxiliary clamp, adjustable clamp and small needle clamp (
The smaller the better)
This is what a toothbrush looks like.
Here you can see the dividing line near the center of the separate brush for the battery box.
Clip the deputy fixture to the upper part and then use the regulator on the lower reverse counter-clockwise.
Some brushes are harder to break the seal than others.
Unscrew the lid.
This is a separate battery case.
Remove the battery by pry the metal contacts open and pull the battery up.
Insert a new battery.
In the absence of actual contact with the battery, bend the contact as close as possible to its original position.
Many posts on the web about this topic suggest playing with contacts and trying to get the switch to work properly.
Personally, I have no patience.
In my opinion, the following work is the same for on/off operations and is not so troublesome.
Bend the label on the contact back and squeeze it down as close as possible to the contact.
By doing so, you will effectively remove the on/off switch from available.
Screw the lid back.
Should start when the brush is fully tightened.
Simply unscrew the lid for a quarter or half a circle to close the brush.
