Battery problem on my Bosch vacuum cleaner, what should I do?

The German brand Bosch is recognized worldwide for its quality and reliability of products. And yet, like any electrical device, it sometimes happens that its devices encounter malfunctions and in particular at the level of the batteries since these are ultimately relatively fragile.

So before giving in to panic, be aware that not all battery problems mean that your vacuum cleaner is dead or does not require the intervention of the after-sales service. Some can be solved on your own. So, without further ado, learn more exactly in this article what to do when your Bosch vacuum cleaner has a battery problem?

Battery problem on a Bosch vacuum cleaner: what to do?

After having verified that the problem with your battery is not from the power source (out of service electrical outlet, faulty power strip or extension cord, or poor charger connections) you will need to try to identify more exactly the origin of the problem on the vacuum cleaner.

Bosch vacuum cleaner battery problem what to do?

Indeed, if the Bosch vacuum cleaner battery no longer charges, lights flash abnormally, or the battery no longer holds a charge, the problem may come from different elements : the charger or the charging connectors, the conditions of storage or use, the power card or even the battery itself. Then follow our troubleshooting guide in order to carry out a correct diagnosis of the fault and thus attempt to resolve it effectively.

Check Bosch vacuum cleaner charger

If no charging lights are on, they come on intermittently or abnormally, it may be that the charger is faulty. Therefore, either your Bosch vacuum cleaner's battery will charge very slowly, or it won't charge at all.

To start, perform a simple check by observing whether the power cord shows signs of damage. If you notice that it is bare, blackened, melted or has small cuts, it is likely that the wires inside are also damaged and therefore no longer transmitting the voltage necessary for the battery to function. properly.

Also make sure that the plugs (both tips of the charger) are not bent or damaged and that they fit securely in the power socket and in the connector of the vacuum cleaner. Finally, dust the tips and connectors using a special compressed air spray for electronic devices. Remember to wait for the product to dry before performing another test.

It is also possible that visually everything appears normal, but that the internal connections (wires, transformer etc.) are faulty. To push the test, it will be necessary either to use another charger, for example by borrowing that of an acquaintance, or by detecting the voltage at the output plugs of the charger. To do this, you will need to use a multimeter set to direct current (voltmeter). If the charger is not faulty, you should find the voltage about the same as what is listed on the charger. If not, the charger is likely responsible for the battery issue on your Bosch vacuum cleaner. In this case, you will have to replace it.

If your vacuum cleaner is under warranty, contact the Bosch holder to get a change free of charge. Otherwise, you can find a charger certified and compatible with the model of your vacuum cleaner on their website, section detached pieces. You can also find it on an independent site. Make sure that the new charger is certified or qualitative to avoid any other inconvenience.

Check the charging station and the connectors

In case the battery problem on your Bosch vacuum cleaner occurs while you are using a docking station and wall charging, it will then be necessary to check if the problem does not come from this element. In this case, start by cleaning and dusting the tips and connectors using a compressed air spray specific for electronic components. Remember to wait for the product to dry before performing another test.

If the battery problem persists, check the voltage at the terminals where the device sits. To do this, use a multimeter set to the voltmeter position (direct current). If you find that the base does not provide voltage or a voltage that is too low, then it will need to be replaced.

In the event that the battery problem on your vacuum cleaner comes from the docking station, then it will need to be replaced. If you are entitled to the guarantee, call the Bosch holder for a free replacement. Otherwise, find it on their website, section detached pieces by entering the model of your vacuum cleaner. You can also find it on an independent online site. Once again, pay attention to the quality and compatibility of the battery with your model.

Control the battery storage and usage environment

If your device refuses to turn on or charge, the lights turn on abnormally, it may be that the battery problem actually comes from the environment in which you stored or used your Bosch vacuum cleaner. This is because the vacuum cleaner should not be used or stored in extreme temperatures. More precisely between 5 ° C and 40 ° C.

This is explained because the vacuum cleaners have a thermal security which is activated when it is in extreme temperatures. This avoids damaging, tiring and wearing out the battery too quickly. If you find yourself in this situation, then move your Bosch vacuum cleaner to a place with suitable temperatures.

Check the status of the battery itself

If after the few previous checks and manipulations, the battery problem you are having on your Bosch vacuum cleaner persists, unfortunately it's a safe bet thatit is defective.

Indeed, over time and by recharging, the batteries end up getting tired. Overnight, even without a warning sign, she can then give up the ghost. When this happens, usually the charging lights flash and then stop after a few seconds or minutes. The lights may also flash but never indicate full charge. Finally, your battery may charge but last only a few minutes or even seconds when you turn it on. In this case, the battery is at the end of its life.

Sadly, a battery failure cannot be repaired on your own on all models of Bosch vacuum cleaners :

As regards the Bosch Unlimited upright vacuum cleaners, you can test and replace its battery as they are designed to be interchangeable. To make sure that the problem comes from the battery, you can either, of course, replace it with another battery; or if you do not have one available, test the voltage at the terminals drums. This measurement is made after charging the battery for at least 3 hours. Note that it is also done off. If there is no voltage across it, then replace it.

Unfortunately, other models of Bosch vacuum cleaners (Athlet, Readyy'y, Flexxo etc) do not have an interchangeable battery. It is therefore not intended to be replaced. Consequently, the dismantling and the test on the battery are manipulations reserved for a . Indeed, in addition to the fact that the handling is very complicated, you might have trouble obtaining the necessary spare parts. Also note that if the vacuum cleaner is still under warranty, dismantling you will lose the rights. Know now that if your vacuum cleaner is no longer entitled to warranty, the electronic card will have to be replaced at the same time as the battery and that the amount of the repair out of warranty can be very high.

What to do if despite everything the battery problem persists on your Bosch vacuum cleaner?

If the problem of battery on your Bosch vacuum cleaner persists, if you have not succeeded in diagnosing the origin of the fault or if you have the slightest doubt about the identification of the fault, you will then have to contact the Bosch Service. In addition, be aware that the failure can also come from another electronic component internal to the vacuum cleaner, namely a failure on the charging circuit (electronic card) or another internal connection. At this stage, it will therefore be necessary to carry out much more in-depth tests and manipulations to successfully resolve the battery failure.

That your vacuum cleaner is covered by the guarantee or not, we therefore advise you to contact Bosch support by mail, through phone or by requesting a intervention of a technician on their website. However, we recommend that you first contact them by phone to try to resolve the breakdown with an online advisor. Indeed, he can tell you the manipulations corresponding to the model of your vacuum cleaner, then tell you the options that are available according to your situation.

Be aware that if your Bosch vacuum cleaner is no longer eligible for warranty, you can also decide to call on an independent professional repairer. The service rendered will probably be faster if it has compatible spare parts. On the other hand, do not hesitate to ask the price of the diagnosis and the repair.

    • Hello,
      Have you tested the charger? Otherwise, the battery is most certainly at fault and you will unfortunately have to replace it... We still advise you to test it (or have it) tested to be certain that the problem is not due to a bad contact and therefore to faulty connection. Good luck

  2. Hello, we bought two Bosch Readyy'y series 2 stick vacuum cleaners a little over a year ago and the batteries of both no longer hold a charge?
    Is this model defective?

    • Hello
      If both failed at approximately the same time, it's possible. We advise you to contact Bosch customer service for more information on this subject (we are an independent blog not related to Bosch service).
