The oral b toothbrush does not charge. When to change the battery. Water gets inside

A couple of years ago, having tried an electric toothbrush, I learned Zen.
As in the song - robots work hard, not people (s). There is much less plaque, the duration of the procedure regulates - you won’t profilone.
My choice then fell on the Braun Prof 500, the initial one in the professional line, without the bells and whistles.
Then they fell in love with Oral-B and now these brushes are under their brand.
Inside is a non-removable Ni-MH element, here the manufacturer clearly laid down “programmed aging”. The memory effect after three years led to the expected - the charge is barely enough for one cleaning.
But as it turned out, a regular AA ni-mh battery is suitable for recovery.

We disassemble the device:
- remove the bottom cover (this cover is placed in the charging glass), the cover is spring-loaded - after opening we take out the spring.
- from above we press on the metal pin (where we put the nozzles), squeezing the entire mechanism down.
- then we disassemble the mechanism itself, we need to unsolder the charging / control unit from the engine:

Disassembled internals

We disassemble the battery compartment, solder the Ni-MH element.
Native element from the factory 800-900mAh, no more. Length 42mm. You can look for a similar one on ebay. I tried to discharge-charge it in Imax b6 - barely 250 mAh capacity was accumulated.

Comparison of native element and donor

Next, we tear off these petals (tabs) and solder them to the donor.
I had a regular Eneloop AA on hand, I used it. I think you can get by with an ordinary element, but don’t chase huge capacities, I’m afraid the built-in charger is not designed for a large capacity and the full charge time will be measured in days.
For soldering in this case used acid, it gives a quick tinning without overheating the battery. Soldering iron contact no more than a couple of seconds.

soldering acid

In order for the AA element to enter its native place, you need to break out or solder the restrictive plastic stops in the battery crib with a soldering iron. As far as I understand, the entire design of the mechanism is the same for the entire series of brushes, on more expensive models a bed is installed without these plugs under AA size (49mm) and marketing can report 2 times more work time and ask for X times more money. Not a discovery, of course, but every time you encounter it, it leaves an unpleasant aftertaste.
We assemble in reverse order.

Total, before pushing back

Also, the brush may not start on the button after replacement, you need to put it on the charging base for 5 seconds and everything will pass.
As usual, if you decide to break something, do it at your own peril and risk, I'm just sharing my experience.

From year to year, electric toothbrushes are becoming more common, and large quantity people are switching from using mechanical devices to electrical, more advanced gadgets. This is explained not only by the fact that such devices cope with their task more efficiently and effectively, but also by the fact that today they have become quite cheap. Of course, you still need to pay more for an electric brush than for a manual one, but its properties fully pay for themselves. In the modern market, such a device is represented by a mass of brands and an even greater variety of models, which, in turn, differ the widest list characteristics and technical differences. The choice can stop at the simplest products at a price of $ 10, as well as those whose cost exceeds $ 100 or more.

Of course, given that today even toothbrushes have become “smart” and electric, such devices require some care. And so today we want to consider information on how to care for and repair toothbrushes.

Caring for Electric Toothbrushes

To begin with, we propose to consider information about what care should be for such important hygiene devices. In order for your brush to serve you as long as possible, and the cleaning effect to remain at the same quality indicator, we recommend that you familiarize yourself with the tips described below:

Carry out systematic rinsing of the brush. Both before and after the cleaning procedure, it is necessary to rinse the brush under running water. In this way, you can remove various debris from the bristles. You can not worry about the safety of the device, as modern brushes are moisture resistant and are not exposed to water;
After brushing your teeth, always check the charge level of your toothbrush so that the next time you brush your teeth, you will not be surprised by a “pleasant” surprise in the form of a dead battery;
Always keep the device upright. It is recommended to dry the brush only in a vertical position, installed in an empty dry glass;
Change nozzles at least once every few months. As with mechanical toothbrushes, electrical devices also require periodic replacement. Fortunately, this does not mean buying a new device, but only purchasing a spare brush head. Having completed such a replacement in a timely manner, you can count on the fact that the effect of brushing your teeth with an electric brush will not decrease, and the nozzle itself will not be a breeding ground for microbes (after all, when using nozzles for more than 3 months, they begin to accumulate a lot of bacteria in themselves);
When changing nozzles, it is necessary to perform a cleaning procedure, which involves thorough rinsing under running water. Apply heat treatment(like boiling) is not recommended, it breaks the structure of the bristle fibers.

Using a sterilizer

Another important aspect when caring for an electric brush is the use of devices such as a sterilizer (they are also called disinfectors). This is a small device in the form of a case or cup, which serves to perform a more thorough procedure for sterilizing a toothbrush. Thanks to the use of an ultraviolet sterilizer, you can be completely sure that the brush will be completely sterile and ready for use after each sterilization procedure.

Some toothbrushes are sold immediately with such devices in the kit, but this only applies to more expensive gadgets. If you want to purchase a disinfector separately, this is a fairly rational solution, but you should be prepared for the fact that such a device can cost like a budget electric brush - from 10 to 20 dollars (and some models even more).

How to charge an electric toothbrush

next very important question regarding the operation of the EPS, is the correct use of the battery resources of the device and the extension of its life. Many consumers who systematically use electric gadgets for brushing their teeth mistakenly believe that the surest solution is to recharge the device daily, simply by keeping the brush on charge all the time that the gadget is not in use. Of course, such a hypothesis is doomed to failure, and such actions can only lead to a prompt failure of the battery and the need to replace it. In fact, caring for a brush battery should be different, and below we will look at good advice from experts.

It is worth noting that some of today's popular electric brush manufacturers assure their consumers that recharging their devices is not possible. That is, if you leave the brush always installed on the base for charging, there will be no problems with it, the charge will reach the maximum, and the device will automatically stop charging. However, this is not the most practical solution, so it is not recommended to use it.

In addition, it is important to note the following nuances:

A full charge of the brush should be enough to use the device for regular brushing in a week. If you begin to observe a decrease in battery functionality, this means that it has gradually begun to exhaust its resources and will soon require replacement;
To fully charge the brush, depending on the manufacturer and model, it can take from 12 to 16 hours.

Before charging the device for the first time, it is recommended to carefully study the instructions, which contain information about proper charging. If we talk about the most popular devices made by Philips or Braun Oral-B, then such brushes can be stored at the charging station all the time, however, if you keep the brush in the bathroom, it will simply be inconvenient to keep it plugged into the outlet. Therefore, we recommend you the most best option– charge once a week, but regularly check the charge level of the device to avoid problems with premature battery discharge.

How to disassemble an electric toothbrush

Finally, we want to pay attention to the procedure for disassembling toothbrushes. different manufacturers. After all, replacing the battery is not the only operation that brush users may need to perform during their operation. Therefore, it is important to know how this gadget is properly disassembled.

You must follow the instructions below:

Check your device and make sure it is turned off.
Dismantle the nozzle.
Remove all brush elements that are attached without additional funds like screws.
Check the unscrewable elements, and unscrew them if possible.
If a we are talking about how to disassemble an electric toothbrush from Braun, Philips or similar brands, the electric base with the board and the brush controller is installed in the body without using any screws for fastening. Take pliers or tongs, and with their help, securely fixing the rotating element of the brush, pull it towards you. The base of the brush is installed in the body and is fixed with a rubber ring, with effort, you can get it.
The brush can be considered disassembled.

All other elements of the base are disassembled as simply as possible and do not require separate instructions. You may need a small shaped screwdriver to remove the screws. By disassembling the brush, you can:

Replace diodes;
Replace the battery;
Replace buttons and other damaged elements;
Remove and replace motor.

After doing necessary operations with EZSC, its assembly is carried out in the reverse order.

What to do when the battery fails

If you have been using your electric brush for more than a year, you have probably noticed that its battery is no longer enough for long periods, as it was before. Battery wear is absolutely normal phenomenon, and you can fight it. The ideal solution is to buy a new battery and install it in place of the used one.

Even though the battery is a non-removable part of the brush design by default, replacing it is not that difficult. For this purpose, you can use next instruction:

Remove any removable structures from the brush, such as a nozzle.
Locate the nodes of the device that are attached to the case with small screws and unscrew them.
Disassemble the device.
Get to the battery and remove it.
Remove the element from the Ni-MH battery that is used to connect it to the contacts in the battery compartment. This may require the use of a soldering iron. The dismantling procedure is extremely simple - touch the hot soldering iron tip to the element, wait until it heats up and frees itself from tin.
Take the battery purchased earlier for a replacement.
Similarly, using a soldering iron and tin, secure the Ni-MH cell to the new battery.
Return the battery to the compartment and assemble the toothbrush.
Check the operation of the device with a new battery.

In this way, you can replace the battery in the Oral-B Triumph toothbrush and many other models, as well as brands such as Philips. As for the direct purchase of replacement batteries, today you can buy such elements on well-known sites, like:

Ebay;
Aliexpress;
gear best.

Now that you know how to care for, charge and repair toothbrushes, you will be able not only to use this device correctly so that it lasts you as long as possible, but also to independently remove and replace its elements in case they fail.

In 2011, I was lucky enough to snatch a Braun Oral-B Triumph Professional Care 9000. I walked around it in circles for half a year, but the price of $100 was above my psychological maximum. Then bam and $50!!! I'm in shock, the toad too. I had to take. The brush is really great. I would like this in childhood - there were fewer holes in my teeth. I buy replacement tips on eBay. Naturally not original. Only once got slag. Usually the spring is made of stainless steel, but here they slipped it out of steel. I threw out the whole set.

Until 2016, there were no problems with the brush. In 2017, the battery began to fail. Threshed weakly, the charge went quickly. So I made it to 2018. Last month started glitches with the display of the charge. Shows 100%, turn on 0%. It's time I thought. If you drive in a model on eBay, then the prices for the battery are hell and Israel. Thank you at least the size is indicated. Asked the right question to Google and got the answer:

standard sizes of batteries and accumulators

It turned out that the Braun Oral-B Triumph Professional Care 9000 costs a Ni-Mn 4/5A 1.2 volt battery with a nominal capacity of 2200mAh. Prices on eBay immediately became adequate. Bought two PKCELLs for $5. Checked on iMax-B6. 2700mA is poured, 2200mA is drained at a discharge current of 800mA. Killed showed 1500mA.

There is a great disassembly video on youtube:

Cordless toothbrushes have been clinically proven to remove plaque better than regular toothbrushes. Although they are relatively expensive, with proper care, these brushes will last at least 5 years. The brush heads are easily interchangeable, allowing the whole family to use one electromechanical handle, and each one has their own toothbrush.

How does it work

The cleaning action is provided by the orbital movement of the brush head fixed on the end of the shaft of the head holder. The hollow barrel includes a miniature gearbox in its design and is put on the drive spindle in the handle. The handle, which is made in the form of a non-separable unit, contains an electric motor, an electronic control unit and a rechargeable battery. Some handles have an external switch slider. In other models, the switch button is covered with a flexible rubber-like cover.

Charger

Each brush is supplied with a charger, on which the brush is installed to recharge the battery. The charger is also an insulated one-piece design - charging is done inductively and there are no metal contacts electrically connecting the handle and the charger. Therefore, the cordless toothbrush can be used perfectly safely in the bathroom, and the appliance is equipped with a two-pole plug for electric shaver sockets. If there is no outlet for an electric shaver, then the charger can be plugged into any outlet in the house through the appropriate adapter. A compartment for interchangeable brush heads can be provided in the charger housing.

Battery charge

When charging a new toothbrush for the first time, place it on the charger and the indicator light will come on to indicate that it is charging. Leave it to charge for the time indicated in the instructions (usually 16 hours), and then remove the brush from the charger and let it work until it is completely charged.

Rice. 2 Charging an electric toothbrush

Put the brush back on the charger and charge for 16 hours or as directed by the manufacturer. To keep the battery in good working order, it is recommended to repeat this procedure approximately every six months. For optimal use, it is best to keep the brush on the charger in constant recharging mode - the battery will not take “too much” charge.

reciprocating motion

To improve the cleaning effect in the latest models, a reciprocating component has been added to the orbital movement of the brush head.

Two Minute Warning

Cordless toothbrushes have a built-in timer that, after 2 minutes, causes the brush to work intermittently for a few seconds - this is a signal that the minimum recommended brushing time has passed. The motor then runs normally again so you can continue cleaning. On some models, you can select the driving speed to avoid discomfort at sensitive teeth and gums.

CLEANING THE CORDLESS TOOTHBRUSH

Rinse the brush under running water after brushing your teeth. Rinse the brush head and holder shaft with water and dry with a paper towel or tissue.

About once a week, remove the brush head and flush it through the tail section to flush inner part. Wipe the drive shaft and handle with a damp cloth. If you have hard water, do this more often to avoid mineral salt deposits.

Rice. 3 Cleaning an electric toothbrush.

If black deposits start to build up on your brush, don't use whitening toothpaste. This generally harmless discoloration is caused by bleach deposits in the crevices of the toothbrush.

The coating may not be visible under the slide switch of older models. To clean this area, move the slider back until it disengages and scrub off the buildup with a nail brush under running water. When all parts are clean, you need to press the switch and slide it forward so that it falls into place. Be careful not to flip the engine backwards.

Unplug the charger from the outlet from time to time and wipe it with a damp cloth. If your device has a brush head storage unit, remove it and rinse under running water. Dry the unit well before reinstalling it.

Spontaneous activation of the toothbrush

Water got inside

A crack in the housing or a torn rubber covering the switch button can allow water to enter the brush. This defect cannot be repaired.

Green indicator not working

When the brush is placed on the charger, the green indicator light should come on. Make sure the charger is plugged in and check the following:

No power

If other devices in the same circuit have stopped working, check the shield for a blown fuse or tripped circuit breaker or RCD.

The presence or absence of voltage can be shown by a non-contact tester if they touch the base protrusion on which it is placed Toothbrush.

If the charger doesn't seem to be working, then you'll almost certainly have to buy a whole new set.

BRUSH DOES NOT WORK

Water gets inside

If the brush is dropped, its body may burst and water will get inside.

Too much force on the spindle when brushing your teeth can damage the seal and cause it to leak.

The rubber cover on the power button may break and expose water to the inside.

With any of these damages, the cordless toothbrush is most likely beyond repair.

Battery not charging

The rechargeable battery may fail. First test the charger with a non-contact tester (see above). If there is tension, ask the service center if it is possible to replace the toothbrush itself.

Faulty charger

See above..

Time and pressure indicators

Brushes are made with colored bristles, which should fade after a certain time, and this is a signal that it is time to change the head. Dentists recommend changing the brush head after three months of use anyway, and even earlier if the bristles are bent or deformed.

Bent bristles are a sure sign of excessive pressure on the brush; only light guiding pressure is required. The latest models are made with this circumstance in mind. This may be a spring-loaded head that responds to excessive force, or intermittent operation, etc.

THE MAIN THING - SAFETY

Batteries must not be disposed of with household waste. In case of failure, return them to the manufacturer's service center, where they will be safely disposed of.

Good luck with the repair!
