replace battery on oral-b pulsar

[darkoshi]

Oh wow. I was just able to successfully replace the battery on an Oral-b Pulsar toothbrush.

After unscrewing the handle, don't pull back on the small end-part of the metal strip, so that the battery can be pulled out. That is what I tried on a different toothbrush, the last time. The metal will either break, or you won't easily be able to bend it back into the right position after replacing the battery, so that it still exerts the right amount of pressure on the battery. I tried putting various things in the end of the cap to push on the metal, but none worked reliably for me.

Some people have found work-arounds using the above method, but I didn't try that way again. Also, in my toothbrushes, the battery didn't have a bump on the negative end.

Instead, I took a small screwdriver and carefully pulled/bent back the metal where it is wider, on the side. It took some effort, as the metal was curved in the opposite direction that I was pulling in. Then while pulling it back like that with one hand (just far enough as is necessary), I pulled the battery out with my other hand. Then after replacing the battery, when you screw the end back on, it presses the metal back into the correct position. It did me take a few tries to get the end to screw back on though.

Fine, you can change the battery making it last for a very long time, but how long are the brush bristles designed to last. I would think the brush head should be changed at least every 3 months or sooner. Is the battery life shorter than this.
I use a rechargeable Philips Sonicare with replaceable brush heads that I've used twice a day or more for the past 10 years or longer.

In the web article you referenced the toothbrush in the final photo looks brand-new and not like the same dirty grimy scratched-up one in the other photos. I wouldn't want that one in my mouth.

The scratches are probably from the pliers they used.

I don't keep track of how long I keep my toothbrushes, but I replace them after a while when I feel it's time. So I can't say for sure if it has been less than or more than 3 months with this one so far. But also, I've only been using it once a day, as I have 2 different toothbrushes that I switch between.

We have a Philips too with a separate brush head for each of us, but neither of us have used it in a long time... I'm not really sure why we stopped using it.

Just for reference, the new battery I had put in one month ago is already dead, even though I've only been using the toothbrush once a day. There were at least 3 days during that month which I didn't use that toothbrush, while I was on a trip.

I think I must brush my teeth longer than other people tend to do - maybe that is why the battery doesn't last long for me.

Thanks man, finally it worked! with my first one I did what you say 'don't', ruined it and used it as a manual toothbrush in the end. Now I did what you suggested for my 2nd toothbrush and replaced the battery easily. I put some aluminium paper to fill the space(orginal duracell battery is a bit longer) and voila :)
