Electric toothbrush charged for a long time and still can t be used?

I've used two broken electric toothbrushes, broken and dismantled, repaired and broken.

There are generally two scenarios.

One is that the battery inside is no longer working, and it can't be charged. Generally, it is a nickel-metal hydride battery, or it may be a lithium battery, take it apart and see if it is replaced. Oh, easier said than done, electric toothbrushes are hard to remove.

The second is that there is something wrong with the micro motor, the inside of the toothbrush is very wet, and it is easy to jam the shaft, and the motor needs to be lubricated or replaced.

The third is that the switch contacts are oxidized and should be scraped.

Fourth, the control circuit is corroded or the components are broken.

That's basically it.

Of course, if it's a problem with the charger or charging cable, I'm talking about it in vain.

If your electric toothbrush still doesn't work after charging, there may be a problem with your electric toothbrush. You have to go to customer service and they should be free to return or exchange the item. You insured your entire team for freight and can replace it if it breaks within a year.

There are several possibilities for electric toothbrushes to be charged for a long time but cannot be used:

The first possibility is that the electric toothbrush itself is damaged. ......The second possibility is that there is a problem with the charger and the electric toothbrush is not being charged at all.

Both of these conditions will make the electric toothbrush unusable.

If the electric toothbrush is charged after charging.

If it still doesn't work, there may be a problem with your electric toothbrush. You have to go to customer service and they should be able to return and exchange it for free. Your product line is covered by shipping insurance and should be replaced if it is damaged within a year.

If your electric toothbrush doesn't work after charging, there may be something wrong with your electric toothbrush and you'll need to find customer service, who should be able to replace it for free. Your squadron has shipping and if they break down within a year, they should be replaced.

The note is broken or the battery is dead.

The electric toothbrush can't be charged to the reason:

1. The battery is aging and its life has arrived; After using it for a long time, the battery of the electric toothbrush will not be able to be charged because of the end of its life, unable to react to electricity.

2. There is interference during wireless charging; If this is the case, it is only necessary to check if there is a foreign object obstructing the charging process, whether it is placed correctly at the charging port, and whether it is placed in the center of the charging port.

3. Do not use the original charger when charging; If you do not use the original charger, it is easy to cause damage and cannot be used for a long time, in this case, you can continue to use the original charger provided by the purchase seller.

4. If there is no charging for a long time, the battery will be discharged to produce the battery memory effect; If the battery is not charged for a long time and the battery is kept low, the battery can only remember the small amount of electricity put in by the user, and the device will automatically stop charging if it is not fully charged when charging. This requires users to maintain good usage habits and use the toothbrush until it automatically turns off the power, and then fully charge it.

1. If the battery cannot be charged, the electric toothbrush will still rotate very slowly after a few hours of charging, and then it will stop after a while. This shows that the battery of the electric toothbrush is broken, the general battery is a lithium battery, which is the same as a mobile phone, you can find an after-sales service for maintenance, or you can buy a lithium battery of the same specification where the electric toothbrush is sold, or buy a new electric toothbrush;

2. The charger may be broken, you can check whether the charger has power after plugging in the power supply;

3. If the charger and battery are fine, it may be a circuit problem inside the toothbrush, such as a broken circuit. It is recommended to contact after-sales maintenance.

Electric toothbrushes are mostly advertised as being able to vibrate quickly and effectively remove plaque, however, foreign studies have found that electric toothbrushes can clean teeth when compared with manual toothbrushes.

Electric toothbrushes generally take 12 hours to charge, if you are in a hurry to use, you don't need to charge them all at once, and the toothbrush can be used with a certain amount of power after charging for a few hours. The electric toothbrush can be used for two or three weeks after it is fully charged, and when the toothbrush sends out a low battery reminder, it is best to charge it in time, and do not plug and unplug it frequently when charging, so as not to damage the battery.

Electric toothbrush charge for 12 hours

Electric toothbrushes generally need to be charged for 12 hours to be fully charged, and general electric toothbrushes can be charged continuously. If you are in a hurry, you don't need to charge it all at once, you can use it once in a few days, so it won't damage the toothbrush.

After an electric toothbrush is fully charged, it can last for 2 to 3 weeks after using it for two to three minutes each time. When the toothbrush sends a low battery warning, it is best to charge it in time. Do not plug and unplug at will when charging, otherwise it will damage the service life of the battery.

It is recommended to buy a rechargeable electric toothbrush, and when there is no power, you can charge it directly like a mobile phone, which is convenient and environmentally friendly. Toothbrushes that use dry batteries drain power very quickly, and they need to be replaced with new batteries soon after, which can also pollute the environment.
