More Mileage Out of Your Oral B Pulsar Toothbrush
Intro: More Mileage Out of Your Oral B Pulsar Toothbrush
For around $5 you would think the battery in an Oral B Pulsar toothbrush would last a little longer. Here is how I overcame that problem.
STEP 1: The Tools That I Used
These are the tools I used. A pair each of vice grips, adjustable pliers, and small needle nose pliers (the smaller the better)
STEP 2: The Brush
This is what the toothbrush looks like.
STEP 3: The Seperation
Here you can see the dividing line near the center of the brush where the battery compartment comes apart.
STEP 4: The Grip
Clamp the vice grips on the upper portion then using the adjustables on the lower portion twist counter-clockwise. Some brushes are more difficult than others to break the seal. Screw off the cover.
STEP 5: The Guts
This is the separated battery compartment.
STEP 6: The Removal
Remove the battery by prying the metal contact out of the way and pulling upward on the battery.
STEP 7: The Replacement
Insert the new battery.
STEP 8: Making Contact
Bend the contact as close to it's original position as possible without actually contacting the battery.
STEP 9: The Modification
Many posts on the web on this subject suggest playing around with the contact to try and get the switch to work properly. Personally I didn't have the patience. The following works just as well for on/off operation in my opinion and is a lot less hassle.
Bend the tab on the contact backwards and squeeze it down as close as you can get it to the contact. By doing this you will effectively remove the on off switch from being usable.

STEP 10: The "ON Position
Screw the cover back on. When fully tightened the brush should start up.
STEP 11: The "Off" Position
To shut off brush simply unscrew cap a quarter or half turn.

The method is nice,but using such clamps could damage the brush handle.
It's better to protect the handle using electric insulating tape before clamping. Also you can knock on the handle using small hummer then detach the battery cover using your hands. so no need to use clamps.

The 3-4 months "life" is about the bacteria more than the bent bristles. While you have the battery out you can sterilize the brush with Listerine, alcohol, Steradent or baby bottle sterilizer solution.
There's a guy on YouTube worked out that the 12th ridge down from the brush is the place to push a screwdriver in to release the catch. The whole vibrator motor, switch and battery slides out the bottom. When you change the battery this way you don't disturb the spring clip and the switch works as intended when you re-assemble.
Don't forget when the brush head finally croaks you can cut it off and file it smooth. Fit a new battery and you can slide it up your jacksie for cheap thrills ....Much more convenient than sticking the old Nokia up there and calling the phone repeatedly !

American dental association says 3-4 months, eh I was a month off but I'd rather not risk the chance of oral infections because of the bacteria a toothbrush harbors over time.

(And would it be suitable for making a Bristlebot?)
