Am I correct in assuming that when the battery dies you must buy a new unit? How long can I expect my new brush to operate before this happens?

I bought mine 3 years ago and it is now just starting to lose its charge faster than it used to.

Your assumption is correct. The battery/batteries is/are not user replaceable. The factory warranty is two years, but mine is dying quickly at the four year mark. I've just ordered a 3000 from Amazon.Proper charging will lengthen the life of the brush. My old Oral-B had NiCad batteries and had to be fully discharged about once every six months. I don't know what the battery composition is for the newer brushes. In my case, I think water damage may have caused it's demise.

I am having the unevenness in power just two months after the two year warranty expired :(I still like the Oral-B toothbrush but I think I will buy a cheaper version! I mean if it's going to die every two years.... *shrug*

I've had this toothbrush for at least 5 years (probably longer, but I just can't remember) and am just now buying it again since I've noticed a decline and unevenness in the power. I love the performance and especially the smaller brush heads to get around difficult spots.

It depends...were the batteries alkaline batteries? Alkaline batteries (which I recommend) should last 3-4 months under normal use, brushing 2-3 times a day. If the batteries you used were not alkaline or lithium batteries, then having the batteries die after a month would be normal if you brush multiple times a day.

I have had a unit for quite a few years. I thought my battery had died and replacements were expensive. Started looking at just getting a new unit. Then I put the battery back in and it has worked fine for what has now been a couple more years. Don't know what happened, might have been a connection problem????

I got two of these units to replace the existing Model #1275's that I had for 10 years. I never cleaned the inside and wouldn't recommend doing it because of the sensitive electronics inside. I would vacuum the outside. The units should not be painted. The only time the cover needs to be removed is to replace the 9 V. battery every 1-2 years. Removal instructions are imprinted on the cover. The cover twists off so the battery can be replaced and is held by a wiring harness and connector. The connector does not have to be removed from the cover to change the battery. I hope this is helpful. Regards, Bob P.

I was supposed to but it did not come with a brush. Thankfully I had a brush from my previous burnt out older model.

I have the original paperwork and there is no info regarding replacement parts, I also did a web search w/ same results. The price Amazon has is probably the price it would cost to replace & ship the brushes. I'd get a new one (they're a little quieter as well). Sherry

At least for the ones I have had there is no way to replace the battery... You have to buy a new one... It is a problem with the Rotadent which is sad. I love the toothbrush but it is an expensive love.

We're still using the battery that came with the brush, so I haven't tried. We had an older version of the brush and they worked in there. I believe most items use NI-MH or NiCad AAs as if they were just AAs. As far as I know, the only difference is in the charger or charger settings if you have a multi-charger. The ultimate benefit of rechargeables is that they are interchangeable and "green" as far as frequency of disposal.

Pat, I do not know the answer, but strongly suspect that the battery _is_ replaceable. Reason: All of the other parts of the unit are not specifically made for this sprayer, so the battery should fall into the same category. If you have not yet purchased the unit, you might want to call the manufacturer. If you have purchased the unit, check the parts list to see if a battery is available. If you battery has failed, then disassemble the unit and remove the battery, then look up the battery on the web. When/if my battery fails, I will update this answer.

No you cannot get a replacement battery. The toothbrush needs to be charged more often as it gets older. I have 2 of them and one is over 3 years old and the other about 2 years old. The older one needs to be charged more but it still works great.

I replace my brush about every 6 months. According to anything you read, your supposed to replace the brush, probably every 30-60 days, however, I use the brush as directed, w/o much pressure (but some, of course), and my bristles are straight and in great shape for an extended amount of time. I feel that I get a significant amount of life out of every brush -better than I initially expected. Additionally, I have tried off-brand brushes, and I have not had a good experience. The off-brand brushes had considerably less power than the Philips brand brushes.

To best of my knowledge, no. It goes and goes, and I've had mine for years before it ran out. Clean or replace your brushes regularly!

When the brush no longer preforms properly You should replace it. All depends on how well you take care of your stuff.

J.Q. - I keep mine plugged in 99% of the time, use every couple days and don't anticipate needing a new battery. This is a wonderful vac - don't let a battery life that might never be an issue stop you from buying this great gadget.

As Rob responded, you should have a timer that lets you know you have brushed long enough unless you have an older model that doesn't have a timer. My first Oral B didn't have the timer.

You need to use a charging base which is included with some package purchases. If your brush was purchased without a charge base, one can be purchased on Amazon. Make sure your model brush and charge base are compatible. Hope this helps.

You are lucky. Mine didn't last long enough to need new batteries. It was a complete waste of money. Sorry I couldn't help.
