What should you do when Dyson V6 starts acting up?

A few users of the Dyson V6 model have made some complaints in relation to their use of the cordless vacuum. For instance, a user is amazed at how their Dyson V6 which was only used to vacuum a 15-flat bedroom floor would break down in the space of two weeks, especially when they have only used it every other day.

Hence, it’s disturbing to some Dyson V6 lovers that a vacuum cleaner that they have spent a few hundred dollars on appears to require replacement in only two to three years. That is why someone who purchases the cleaner at the rate of $428 would expect that it comes in handy, and does not give them issues for the next ten years. However, they are shocked when it no longer functions at its best in less than four. And that’s why prospective users are doubtful about investing so much in a clean environment, because they don’t want to be left stranded.

Dyson v6 Battery Issue

Meanwhile, the real issue with most Dyson V6 users is that they do not pay attention to the battery which the vacuum cleaner uses when the plug is not in, where it has to operate without a cord. Whereas, based on the service instructions received at the purchase of a Dyson V6, the battery has a lifespan of 2-3 years. This implies that once the warranty period is over, a user would have to spend $140 to get another battery. So what you’d need to do when your Dyson V6 vacuum cleaner appears to act up is very simple. And that is working on the Dyson V6 battery replacement by yourself, or spending a few dollars to have someone else do that for you.

The Dyson V6 Battery: Its Lifespan and Possible Issues

At purchase of the DysonV6 battery, a buyer receives a year warranty on the battery. Also, the original battery that comes with the Dyson V6 package is very good, since its single voltage capacity is 4.05-4.12V. Apart from that, its internal resistance is around 23, while the whole pack of batteries carries 148.

Meanwhile, by continuously charging and using the battery, the cell capacity of the battery gets used up. Therefore, it starts from a full power capacity of 4.2V, and then drops down to 3V after consistent use. For example, the table below shows the capacity of the battery cells:

V6 Battery cellCell Capacity (mAH)
From the table, it is obvious that there is a decline in the capacity of the cells. As you can see, each decline is relatively close to the initial 2100mAH, and this marks a decrease of about 50%.

Where the 3V does not run out of power, what happens is that the average capacity of the cells remains at 2.75V which is 1100mAH. That indicates a drop in the battery cell capacity by a whole half. Therefore, there is a reduction in the vacuum cleaner work life from e.g five minutes to two and half minutes, as opposed to the usual one minute that most users experience.

Dyson v6 battery lifespan and issues

Clearly, the reason for the wrongly estimated battery life lies in the effect of internal resistance. For example, where dual batteries are in use and one has an internal resistance of 86 and the other has 148, the difference in voltage is 1.2-1.9V. That is caused by the internal impedance when the discharge is 20-30A.

Apart from this, the Dyson V6 has a protective plate that protects the battery when its voltage drops to 3V before the full release of such battery.

What You Need to Know about the Dyson V6 Original Battery

The Dyson V6 battery is not like the power tool battery that can easily be replaced. Thus, to remove the Dyson battery, you’d have to remove the nozzle and the dust box, and then loosen the two screws on the box. Also, the Dyson V6 powers up to 350W. However, the original battery capacity is quite low as it has only 2.1AH. Yet, the 2.1AH which is unable to withstand a large current discharge results in a high temperature. This means that the protection plate of the Dyson V6 battery which is up to 70 degrees brings a serious decay to the battery.

Another thing to note about the Dyson V6 original battery is that the 18650 battery has a full voltage which holds more than 4.2V. Yet, many power tool brands of lithium battery hold a full voltage of 4.1V. If the battery is not fully charged at its first use, it ends up affecting the battery life. Meanwhile, it was revealed from a Consumer Survey Report that the Dyson battery can easily be lost while in use. For that reason, most handheld vacuum cleaners are not easily preferred at the time of purchasing vacuum cleaners.

How to Choose the Best Replacement Battery for Dyson v6

In making a choice of battery replacement for your Dyson V6, there are a few things you must consider, and they include the following:

Dyson V6 Battery Type

The first thing you need to do is check for battery types that are compatible with your Dyson V6. Generally, lithium and Nimh batteries are required for Dyson V6. However, other battery types would not work well with your vacuum cleaner.

Dyson v6 Protection Plate

A sample battery makes use of the simple MCU for its main control management. Then, a discharge is marked by a single MOS tube. Therefore, there needs to be an Anti-reverse charging protection diode of diode of 1N4007, and a charging tube of PT4407 to protect the batteries from damage.

Dyson v6 Battery Protection

Where the battery has a larger difference in voltage, there is a high risk of over voltage. However, where the voltage is low, there is a high level of protection to regulate it. Therefore, where you’re charging a battery with a high amperage, the current that is discharged is low, and it is less possible to protect the battery.

That is why it is important that the battery you are going for has a protection panel. In fact, it is the protection panel that ensures that the battery is safe, and reduces lurking risks so that the battery lasts long.

Discharge Temperature level

Also, it is necessary that you check for the rise and fall in the temperature of a battery so that discharging period is regulated as much as possible. For instance, using a 350W discharge simulation, the battery cavity and protective plate of a MOS tube surface has its temperature data below:

Dyson V6 BatteryMOSCellDischarge time
Dyson V6 1103.576.15.9
Dyson V6 278.581.77.4
Dyson V6 3113.378.67.2
Dyson V6 4136.666.28.4
As seen from the table, a good battery has a discharge time of 8.4 minutes which is 2.5 minutes longer than a battery with poor quality. This implies that the battery temperature is lower. Hence, it is safer to use that particular battery for your Dyson V6.

Dyson v6 Battery Resistance

In attempting a Dyson V6 battery replacement, it is very important that you do not miss a particular step. That is because testing the internal resistance of the battery you intend buying is vital to the use of your Dyson V6. Though the Dyson V6 circuit board only has an over-over-the-top protection, it does not have a balanced charge function. Hence, the need to test the internal resistance of the battery so as to find out whether the battery is fit for purpose, and has a good lifespan each time it is charged.

Use this table as a resistance measure and check:

V6 Battery TypeResistance
V6 VTC5A(Official)69.5
V6 VTC6( Replace)79.94
V6 VTC5A (Replace cell)62.85
As you can see, the data shows that the original battery has a lower internal resistance than the replacement battery.

Dyson Battery Real Capacity

The larger the capacity of a battery, the longer its working time. That’s why you need to opt for larger capacities in your Dyson V6 battery replacement attempt.

However, the capacity marked on an average battery is not real. For example, a battery with a label of 4000mah usually has a capacity of only 3000mah. At times, the capacity is as low as 2000mah.

Below are the specifications of V6 replacement batteries based on the tests performed on them:

Dyson BatteryLabel0.5C True capacity
Dyson V6 130001800
Dyson V6 235002100
Dyson V6 340002300
From the data sheet above, it is thus confirmed that there is a need to examine the real capacity of a battery before purchase. Truly, checking for the real capacity aids the performance of your Dyson V6.
