Just a thought for a solution to charge the Dyson when it has cooled down: Use a cheap $5,- timer socket to turn on at night to have the Dyson charge overnight (may even pay itself back if you have different day/night prices for electricity). No need to deal with cumbersome automation.
This is really useful, but you have to question why its okay with Dyson for you to be in this situation, when you have spent so much money. Needless to say mine is doing exactly what yours was. I only get a few seconds if using it in max. I certainly didn't use max very often previously and it frustrates me that Dyson's advise has been less than clear regarding its use. Basically it is not fit for purpose. If it has a max setting that then slowly kills the battery, you have to wonder if Dyson should be selling it as a model with a max setting, as it cannot maintain this over a reasonable lifetime of the machine.
I've had the same problem . Machine just over two years old. Dyson have replaced the power pack and the filter unit. I can't complain about that. They told me that I shouldn't leave the charger on permanently (I just put it back in the dock whenever I'd used it) and shouldn't charge for longer than 4 hours. Now got a simple mechanical timer which shuts down the power after a maximum of 4 hours.
Like any good smartphone, it needs to monitor battery temp and adjust power usage and charging power accordingly. My son's 140 € Xiaomi note 4 still holds its charge after 4 years (2 days battery life)
My cordless drill batteries are smart enough to not charge when they're either too hot or too cold. The charger waits until it's allowed to charge the battery.
Kinda sad the little battery costs so much for so little. I have DeWalt power tools and the batteries take a beating indoors and out, keep charging and keep working year after year. For the price of one Dyson battery I can get a 9AH battery and can run my leaf blower or weed Wacker twice as long as this vacuum runs. If they really want to replace corded vacuums they need to get on board with bigger and better batteries.
Yep mine died in about 18 months with conservative usage. Now having issues with it becoming smelly and needing a full disassemble and deep clean every couple of months. It can't be used pointing upwards otherwise dust backflows and instaclogs the filter. Two of my motorheads died, third one was about to die (burning smell) when I remembered that means dust is building up around the axle and I was able to recover it with deep cleaning. It cleans well though.
Hi Ben,Thanks for this very useful video! But the only first great problem with all these (too) powerful cleaners is that only one range of cells for so many output/amps is not enough . Specially if used with max power, which kills quickly the good cells...and very quickly the chinese cells. All discharge amps are at the limit , and Lithium hates strong discharges, even with good cells if often used and first of all during a long time. Changing 18650 for 21700 is a poor solution. The best would be to propose also batteries with minimum 2 ranges of cells in // : much longer worktime and first of all much longer lifetime.( like for power drills batteries)...but commercially totally uninteresting...James Dyson is a clever man . I add : don't let the battery connected to the charger (when not used) if the charger is not connected to the main current. In this case the charger will slowly discharge the battery for its own function. friendly from France, Michel.
There was a lot about your video I didn't understand (once you got to the Ikea hack part) :) but I really liked watching it! I think it was your English demeanor! :) Thanks
FINALLY someone has made this absolutely important video about something that I have suspected is causing problems across all models for so many years . I hv been implementing the concepts in your excellent video & my battery lasts years. Obviously I hv been doing it even before this video. Initially I was also avoiding charging until I've discharged to 50%, in addition to monitoring temp. But your video has taught me that the key issue is temp. This is the single most important information for any dyson owner. Thank you!
I must say ive had my dyson v6 for over 5 years now and ive still got the same battery and it lasts for 12 - 14minutes fully charged on normal mode. Ive always drained the battery before recharging it and ive never had problems. Good video though, very imformative.
That was a great video. I love the automation, but there's 1 KeyPoint missing that you may be able to use in your next video ? The key point being lithium ion batteries even this battery in a Dyson has an average 1000 charging cycle life span, This basically means 1000 potentially full charges before the battery's energy starts to deteriorate if a few of my evidence-based factual rules are followed. Basically what I'm trying to say is all batteries should never be charged up unless for some miraculous reason until completely drained, with that being said, they should also not be used until fully charged completely. No interruption from start to finish should occur! If the charge cycle is interrupted The batteries potential energy starts to become depleted prematurely. You made a really good point about letting the battery cool down which is also a KeyPoint as well. The reason being is, all batteries have something called an NTC, which is a NEGATIVE TEMPERATURE COEFFICIENT. This sounds all scientific? Spoiler alert it's really not! You see basically as the temperature increases the resistance decreases so once the battery cools down, it's now at a good state to be charged. For instance your car battery at 0°C loses 40% of its power just like that gone but it's not gone if you simply removed it & brought it inside your house it's back to 100%, just like that! No magic whatsoever just tried tested and proven fact. In reality all batteries have a negative temperature coefficient & must cool down or be warmed up to between 0°C. and 30°C is a good range & 20°C is ideal. The problem is with your automation, which is lovely, but turning on and off the power while charging is counterintuitive to my key point being the 1000 charge cycles per battery average. So each time you interrupt that charge cycle that's another cycle gone out of the 1000 so you're actually decreasing the lifespan of that battery! I promise you what I am discussing with you are all facts! won't bore you with the few things in life I know. I simply just know what I know! I had many battery operated toys as a child but the batteries died quick (cheap parents lol). I was a bit of a SHERMANATOR as a kid to say the least! What I personally do is avoid docking the unit into a powered station. I have and use the docking station but I don't use the power cord. I charge it separately which in turn increases a battery's life span tenfold & only charging it when it is completely dead. No tricking it into getting two more minutes, that's another charging cycle getting lost forever which again decreases the lifespan of the battery. So I guess in hindsight only charge it when it's completely dead & charge it uninterrupted until completely full. Best practice is to wait about a half an hour or at least 10 minutes minimum which is where your automation can come in handy until the battery cools down. Nobody wants to sit around and possibly forget so that that's where your smart plug automation system kicks in while combined with the simple tips I've mentioned? I think your next video might of you working for DYSON, TESLA OR TMMC? Running the battery on high you're right, they backpedaled yes! The heat generated or energy needed or required simply depletes much faster because it generates to much heat which then drains the battery quicker because again the NTC negative temperature coefficient of batteries! All batteries would love to be kept at a cool, 20°C all the time and they would last a lot longer but this is not realistic yet? YET stands for (yours eventually to) I think Mr. Dyson will have some type of heat sink which doesn't draw in air because that would cause contamination, but rather an aluminum fins on the base of the battery which would act as a heat sink further cooling down the battery naturally with the movement of the vacuum and the air flow over the heat sink.Yes, the battery will cost more to manufacture, but it will last up to 20% longer in runtime and lifecycle span. I can solve most engineering problems i feel need to be fixed but I have trouble putting pen to paper. I hear, I forget...I see, I do...I do & I REMEMBER! Take care my friend...
I am on my 3rd Dyson since 2017. My first V7 failed, they sent me another V7 under warranty, because they did not have any batteries in stock. The replacement V7 failed within a year. The warranty had been extended and they replaced the V7 with a V10. Great! But now V10 has failed. Meanwhile, my Panasonic plugin I bought in 2003 still works as new. Are we making progress or not? I will replace the V10 battery myself. I did use it on high power most of the time and I immediately put it on the charger when it quit. I will make the changes you suggest. Maybe that will help. As a radio tech, I worked with batteries for 35 years. I am not impressed with Dyson batteries. Dyson had very good product support, but they did not test their batteries well enough for use in the real world.
I think they need too add a cooldown mode for the charge station too sence the temp and wait for them too cooldown. I always let my batteries cool before i charge them with my tools
true story. and there might be more: our 26months old unit came back from service (replaced broken trigger) with a battery that shows red blinking led indicator for battery failure. this unit only had limited use in our home and the battery didn't show any major degradation symptoms before sending to the service which could withhold 4-5 mins of usage with max setting. now that's a very interesting coincidence which i'll never forget for my future purchases. besides, 2 year warranty for a brand that takes pride in its quality products, is - a - joke!
Thank you. Wow, you have gone to significant effort to work-around this Dyson problem. IMO, Dyson should improve the Battery Management System (BMS) to better control charging, so the battery has time to cool down if necessary, before recharging. Some of my cordless tools have chargers that indicate charging delayed as the battery is too hot, or charging slowed as the battery needs to warm up before charging faster, etc. With Dyson being a premium brand, with a premium price, I expect the best from their products. This is one instance where I believe Dyson can do better. BTW, I have a Dyson V10 that is about four years old, no trouble with the battery pack yet.
Totally agree. That’s all it would take - a 20 minute delay if it’s too hot. They could even do it with software if they don’t want to add a thermometer - I.e if it’s been running on max over so many minutes, then add the delay.
the worst is that you often cant even buy new accus from dyson because they have none in sale for months. they rather offer you a replacement of the whole vacuum cleaner than delivering a new accu. 👀
Here's a idea, Why not stick to old school vacuum cleaners? At least you are not worrying about battery problems and then how to dispose of the lithium battery afterwards.
Because they are crap. The first time you use your Dyson stick vaccum it will make you SO HAPPY you will never go back. The negatives mentioned here are so worth the pure joy of these machines you will only know once you get one.... 💖
So sad. My tineco s12 battery is not working anymore. Both battery. I use on the max setting all the time. It only 6 months the battery is dead. The problem with cordless vacuum is the battery. So sad I can’t find the replacement battery for s12.
I bought a new Dyson V10. One of the attachments is defective. I called Dyson's Customer support. Their response was, "Not our problem. Go to the Seller." What???
I bought my V10 7 months ago and it stopped dead yesterday. Dyson are sending me a new battery as they think that is the fault. I use it, of course i do, but there is just two of us in the house and summertime we are away a lot. I wouldn't say it has had excessive use. Also it is not fixed to the charger, I don't have room, so I charge it at the plug as and when. I had a Fluffy before which gave years of service with the one battery. Disappointed with this now.
Makita have a sensor for battery temperature which will shut down the battery or prevent charging while hot, surely dyson should be able to do this. Probably don't want to show up the limitations of the machine. My V7 battery has started to fail ( a bit too soon in my opinion) and I will be doing the makita battery mod when it fails completely. Then I can swap out batteries when needed with a battery system I already use.
Is there a way to restore life in the battery or once it’s stopped charging is that it? Replacement only option? Wish I’d kept my Henry, best hoover I’ve ever had, cheaper, simpler & just as good, no bells,whistles or fancy lights but it did what it’s supposed to Hoover up stuff.
Lithium cells have a limited amount of cycles, reduced greatly by deep discharge cycles (100%-0%). Unlike NiMh tech from a decade ago where batteries can be "trained" back to full capacity there's no proper way to revive lithium cells. Once they drop below a certain voltage the Battery Management System will stop any current from entering the system as there's a risk of fire. Best tip for longevity is keeping between 80% and 50% charge but this is not so easy to do with a hoover
Outs just started acting up (press MAX it shuts off) so I bought a cheapo replacement battery off e-bay. So far it’s like new again for $50. Maybe we got lucky.
Dyson had to change the design on the battery box. For example, Bosch has a cooling profile on the battery box on later models which means that the cells cool faster. Even the older Bosch Batteries without special cooling hold up well. I have a Bosch 18v battery from 2009 - which still works. I do not know why Bosch battery lasts so well. I use them for tools and garden tools. I'm disappointed with Dyson batteries. The first vacuum cleaner which only had 1 speed and 6 min operating time, lasted 5 years which was actually ok. So I bought a Dyson V6 and the battery is 3 years old and is at 40% capacity. I know how to make the most of the life of these Li-ion cells, but if they are poorly made cells you can not do much to make them last long. I'm glad I do not have an electric car, the cells are not good enough and too dangerous for cars I mean.
Yeah it's all very interesting. Funnily enough I had a Bosh Athlet before the Dyson and we had about 4 or 5 engineer visits in the 2 year warrantee period. Eventually worked quite well and my parents still use it, but I'm not sure what I think about using the customers as quality control!
Yeah, cooling is not as big of the issue as the fact that in dyson v6 and probably still in dyson v11 also they don't use battery balancing, if bms doesn't balance cells then batteries will die pretty fast as we could have seen all those years...
@@ftt2757 Tanks for your replay. A little strange, even Tesla cars cool cells down in hot climates and vice versa. Bosch batteries (li-ion 18 v green serie) are also not balanced and last for many more years, that is my experience.
@@sbromose1 maybe the are not balanced but they don't have bms that checks is they are ballanced, and also what is the wattage used by those batteries per cell ? And i know at least few batteries for powertools that don't have battery cell balancing or even bms in the battery but in those cases they have cell balancing in charger, and power cutoff in powertool
1:14. It is true for any manufacturer, that constant max or boost mode will kill a lithium ion battery. They're not back peddling. This is true. Compare it to a car. It has the option to run at wide open throttle and speed down the highway. Is constant wide open throttle good for the vehicle. No!! Other thing is you have heavy carpet. Thats another thing. You don't clean a whole carpet on boost mode. Boost mode is for quick deep cleans 5 minutes tops without the motorized brush head. ( vacuum operated turbohead). Lots of resistance develops on carpet cleaning in boost mode which creates heat. This in turn creates strain on the battery. I've seen people with Dysons that under normal use still work great to this day. The fault lies with owner operator of the equipment. It's lithium ion batteries that pose issues not the machine. Also every so often the cyclone canister should be serviced. You wouldn't believe how much fine dust and dander can gather outside the cyclone compartment due to static cling. ( the only issue I have with these vacuums, they need to engineer an anti-static cyclone system so that fine dust doesn't accumulate and pathogens congregate. It would be wise that they put UV sterilize technology in the canister). There are youtubers out there the circumvent the BMS ( battery management system) by taking the pack apart or jobbers that make adapters for Dewalt or Milwaukee batteries which is a ticking time bomb ready to happen because it bypasses the BMS code system and can pose a fire hazard. If in doubt it's better to be corded. But proper maintenance starts with the owner/operator. I've picked up a lot of cordless Dysons for chump change because of simple maintenance neglect and improper use and they work fine. I find that boost mode is a fad, because on my anemometer you only gain 5cfm of vacuum and a slightly faster spinning motorized brush bar. Regular mode is just fine. Don't use it in vehicles that are heavily soiled. Use a shop vac.
my dyson 360 eye ran for 5 years. then the accu was down. i send the robot to repair but they were unable to. reason unknown. replacement accus are not available for months now. they wanted to send me a replacement accu for the new dyson 360 heurist that runs out of power after 30 min only. again no accus agailable and they offer the replacement of the whole robot ...
Do not charge it full unless you want to start cleaning soon. A maximum charge of maybe 75 % will help your accu to feel more comfortable for a long period of time. 🙂
There is a design fault, have a battery with all cells in good condition also under load, but the bms keeps giving faults. Hope EU is going to give Dyson a huge fine as they did with Apple.
So your saying not to use boost mode for more than one minute with a one minute rest in between and then also waiting 5 minutes before plugging it in after using the vacuum? You would think Dyson could put a temp sensor in the battery to prevent charging until it reached the correct temp!!!
It's s common problem. I can't believe that Mr Dyson claims 15 years and people believe this nonsense. They claim these are as powerful as a full size machine, BUT it's only when on Max mode! For only 7 minutes.
I'm Brazilian I have a V7 and the battery died in years and a half... I don't like wireless devices I like connecting to ac does anyone know how I can make extensions and use my v7 connected to ac? sorry my bad google english, kkkkk thanks.
I think Dyson pulling the plug on corded machines is a bad idea. Now with the lithium ion issue of not being shipped and kyboshed to many countries for battery development. Apparently shortages of lithium ion batteries are becoming an issue. If anything, he should go hybrid on his vacuums. Going to be a lot of disappointed customers.
18 months is good when I bought Roy dyson v8 animal it came with dead battery so after so much argument they changed my vacuum and send me a v10 . So it worked until I had to charge it. Well it did not charge again so once again I am waiting for them to send me this time the batery
Dyson's battery vacuums have been plagued with poor lifetime for years. My brother had one of their first hand vac's several years ago, and it died in six months. Dyson sent him a new battery and that died even faster. He never got another one.
I thought it was only the v11 you could change the battery? I heard the v10 the battery is inbuilt and can't change it which is one of the benifits of buying the V11?
Opened my v11 last night and let the battery fully charged... tried to use it this morning and the battery is a dud ☹️ I was really looking forward to using it!! Waiting for a replacement battery now 😅
Same thing just happened to me. New machine and was dead on arrival. I did online order, 15 days before we get a new one in the mail. Lots of money to just sit around waiting in parts.
I would have used a system where the battery slides on the side of the Dyson, charging on a remote base station similar to the ones on power tools and having a spare battery when the other one runs down . Doing all these things so your vacuum cleaner can work so you can clean is unacceptable for the cost of this product and thank God Dyson didn't continue his dream electric car because we would have to bear another disaster of a design.
Yeah it'd an appealing idea in some ways for sure- although it does mean another charger kicking around. In principle if the batteries last a reasonable length of time I can make my peace with the compactness and ease of using a 'dock' type charger. I want a good two years from the battery though.
Yes, I’m sick of Dyson’s greed now. I am regularly replacing battery’s for two cordless vacuums that I own (every 2 years or so). I am I no doubt that the battery destroying itself when it is charged when hot is part of Dyson’s planned obsolescence algorithm. To modify the battery to delay charging until it cools would be so simple. All the hardware, including temperature monitoring and processor are already incorporated into the battery. it would just require a software modification I’m sure. But that isn’t in the interest of a moneymaking company is it?
Ha yeah I still easily think it’s worth it. It’s still going strong and has amazing convenience. Still on that second battery, no issues apart from needing filters replacing a few times.
Was thinking of doing an update soon actually. It’s still in daily use. Still on the same second battery. Have gone through a few filters and I did replace the trigger (not a quick or easy job but it benefited from removal of a lot of collected dust inside at the same time). Otherwise no other issues. I’m pretty pleased overall considering the abuse it gets. It’s a shame about the trigger failing and how hard they make replacing it. Still great performance and usability though!
The v11 , the carpet attatchment stopped working after a few uses. Lightly used only.!! They have no tech support. My filter light would not reset. I finally removed the battery, cleaned the filter and it reset and started working again. I can use it , but not the carpet attatchment.. I paid like $450 at Best Buy. Very expensive, will never recommend this vaccuem !!
15yrs!! What a joke! I’m on the 3rd battery in 3 yrs!! 😡. And we might use it once a week. ***Im about to design a power supply for mine so I can use it more than 5-10min. When our V10 dies, we naturally return it immediately to the charger. Sounds like doing that shortens the battery life. -> We have another wireless vacuum cleaner that will run for more than 30 minutes on one charge. It’s also a powerful vacuum, so with the right battery it should last longer.
At first glance my thoughts are that it doesn’t have a fluffy head, or a mini motor head. Both of those are key reasons why the dyson design is so good in my opinion. Would love to give the Miele a good test in real life though.
My thoughts ...If Dyson wanted to produce a really excellent product ...Mr Dyson..ought to look at air cooled chargers, like Metabo or Bosch use ...for their power tools ... supplying a couple of batteries, stops the one battery being precious ...The Sony cells inside the one battery are not custom cells, there off the shelf .. standard cells ... charging bigger more powerful Metabo batteries ...takes 40 minutes max..a Dyson 7 cell maybe 25 minutes, helped by fan cooling ... Mr Dyson is far behind, with his charging and Battery technology...their move to click and go battery’s on new generation v11 is good news, battery’s are however expensive, charger is slow, and will not elongate life span ... very basic slow charging...however Dyson is still the leader...watch out a Chinatown man could see opportunity...Tesla or Metabo could make a better model ...maybe ... ric
Yes and no - the reality is if I changed it every 2 years it would never be an issue due to warranty - but that’s expensive. I’m happy to pay a certain amount for the convenience it offers but not that much! My little ‘hack’ should let me keep the super cool technology for long enough to ensure it doesn’t end up costing too much overall. :)
How long do you think the V10 animal will last if you do all the steps to make sure it doesn’t die fail that fast? I’m looking for a vacuum that can last for at least a few years before replacing it since I think cordless vacuums still have a lot to improve on.
Considering I had been charging it directly after full depletion I think if you avoided that then the 2 years would be easily achievable- but the warranty covered the repayment anyway so you’ll definitely get the two years service (unless they change their position on replacing them!). What I keep thinking about the v10 though is actually how good it is as a full household vacuum - it absolutely replaces any corded machine for us in our 3 bedroom semi-detached. I was anticipating needing to upgrade due to the technology potentially not being good enough to make the concept work properly etc - but I actually don’t feel the need to upgrade to the v11 at all!
@@BenVallack Alright thanks for the info but I don’t think it would’ve been that much of a hassle for them to add a system that detects whenever the battery is cool enough to start charging. That’s the only thing that really bugs me. When I finish vacuuming, I just wanna sit down, relax and not have to worry about when I have to charge it.
@@marsbars4767 yeah definitely agree. Having said that normal day to day use gets no where near empty. The medium power mode is genuinely good enough so the ‘little and often’ approach at that level doesn’t use up all the power so it would be fine to just chuck back on the dock. That said the Ikea hack does also work well when needed!
@@BenVallack Having some trouble deciding between the Dyson multi floor 2 and V10. I have quite a few dogs that bring in a lot of debris like dirt and pet hair that’s mostly on carpet so I need a decent deep cleaning vacuum too. Do you think the V10 will still be enough?
Mine lasted 3 years. If you buy one that has been on the shelf it may not last that long. However, replacement batteries, even 3rd party ones are available, easy to install, and not expensive. So a non issue really.
Yeah I don’t really buy this narrative. They make good products that are expensive. They also offer excellent tech support too. They’re definitely a large greedy corporation with a very creative marketing department but after that I don’t think there’s anything fishy going on.
It’s disgusting that they’re making the batteries like this. I have an 11 year old Tesla and it’s still fine. They’re making these to fail on purpose. Dyson pride themselves on design, but have done a terrible job in terms of battery management. The fact you need to do all this crap with wireless apps an chargers. It’s ridiculous. Also crap design that the batteries aren’t interchangeable. So disappointed in Dyson. 😢
Funnily enough I still wouldn’t have anything else. Mine is still going strong on its second battery now I’m a bit more aware of the battery management.
Actually within warranty they were very good. Also they were very good when I had issues with my fans too. This is still our daily vacuum cleaner by the way, and still going strong on the second battery!
Yep my battery died month after warranty expired. Couldn't even give me 10% off of new battery so I trashed and binned it and bought bosch. Dyson was way more ergonomic and better to use but shitty service sucks.
Just a thought for a solution to charge the Dyson when it has cooled down: Use a cheap $5,- timer socket to turn on at night to have the Dyson charge overnight (may even pay itself back if you have different day/night prices for electricity). No need to deal with cumbersome automation.

i have a box full of dyson batteries. I fixed this by no longer having a dyson - never again!
15 years of daily use??.. really Sir Dyson??, Is that in dog years??
I've had the same problem . Machine just over two years old. Dyson have replaced the power pack and the filter unit. I can't complain about that. They told me that I shouldn't leave the charger on permanently (I just put it back in the dock whenever I'd used it) and shouldn't charge for longer than 4 hours. Now got a simple mechanical timer which shuts down the power after a maximum of 4 hours.
Like any good smartphone, it needs to monitor battery temp and adjust power usage and charging power accordingly. My son's 140 € Xiaomi note 4 still holds its charge after 4 years (2 days battery life)
My cordless drill batteries are smart enough to not charge when they're either too hot or too cold. The charger waits until it's allowed to charge the battery.

It can't be used pointing upwards otherwise dust backflows and instaclogs the filter. Two of my motorheads died, third one was about to die (burning smell) when I remembered that means dust is building up around the axle and I was able to recover it with deep cleaning.

In reality all batteries have a negative temperature coefficient & must cool down or be warmed up to between 0°C. and 30°C is a good range & 20°C is ideal. The problem is with your automation, which is lovely, but turning on and off the power while charging is counterintuitive to my key point being the 1000 charge cycles per battery average. So each time you interrupt that charge cycle that's another cycle gone out of the 1000 so you're actually decreasing the lifespan of that battery! I promise you what I am discussing with you are all facts! won't bore you with the few things in life I know. I simply just know what I know! I had many battery operated toys as a child but the batteries died quick (cheap parents lol). I was a bit of a SHERMANATOR as a kid to say the least! What I personally do is avoid docking the unit into a powered station. I have and use the docking station but I don't use the power cord. I charge it separately which in turn increases a battery's life span tenfold & only charging it when it is completely dead. No tricking it into getting two more minutes, that's another charging cycle getting lost forever which again decreases the lifespan of the battery. So I guess in hindsight only charge it when it's completely dead & charge it uninterrupted until completely full. Best practice is to wait about a half an hour or at least 10 minutes minimum which is where your automation can come in handy until the battery cools down. Nobody wants to sit around and possibly forget so that that's where your smart plug automation system kicks in while combined with the simple tips I've mentioned? I think your next video might of you working for DYSON, TESLA OR TMMC? Running the battery on high you're right, they backpedaled yes! The heat generated or energy needed or required simply depletes much faster because it generates to much heat which then drains the battery quicker because again the NTC negative temperature coefficient of batteries! All batteries would love to be kept at a cool, 20°C all the time and they would last a lot longer but this is not realistic yet? YET stands for (yours eventually to) I think Mr. Dyson will have some type of heat sink which doesn't draw in air because that would cause contamination, but rather an aluminum fins on the base of the battery which would act as a heat sink further cooling down the battery naturally with the movement of the vacuum and the air flow over the heat sink.Yes, the battery will cost more to manufacture, but it will last up to 20% longer in runtime and lifecycle span. I can solve most engineering problems i feel need to be fixed but I have trouble putting pen to paper. I hear, I forget...I see, I do...I do & I REMEMBER! Take care my friend...
I am on my 3rd Dyson since 2017. My first V7 failed, they sent me another V7 under warranty, because they did not have any batteries in stock. The replacement V7 failed within a year. The warranty had been extended and they replaced the V7 with a V10. Great! But now V10 has failed. Meanwhile, my Panasonic plugin I bought in 2003 still works as new. Are we making progress or not? I will replace the V10 battery myself. I did use it on high power most of the time and I immediately put it on the charger when it quit. I will make the changes you suggest. Maybe that will help. As a radio tech, I worked with batteries for 35 years. I am not impressed with Dyson batteries. Dyson had very good product support, but they did not test their batteries well enough for use in the real world.
I think they need too add a cooldown mode for the charge station too sence the temp and wait for them too cooldown.
I always let my batteries cool before i charge them with my tools
true story. and there might be more: our 26months old unit came back from service (replaced broken trigger) with a battery that shows red blinking led indicator for battery failure. this unit only had limited use in our home and the battery didn't show any major degradation symptoms before sending to the service which could withhold 4-5 mins of usage with max setting. now that's a very interesting coincidence which i'll never forget for my future purchases. besides, 2 year warranty for a brand that takes pride in its quality products, is - a - joke!
Thank you. Wow, you have gone to significant effort to work-around this Dyson problem. IMO, Dyson should improve the Battery Management System (BMS) to better control charging, so the battery has time to cool down if necessary, before recharging. Some of my cordless tools have chargers that indicate charging delayed as the battery is too hot, or charging slowed as the battery needs to warm up before charging faster, etc. With Dyson being a premium brand, with a premium price, I expect the best from their products. This is one instance where I believe Dyson can do better. BTW, I have a Dyson V10 that is about four years old, no trouble with the battery pack yet.
Totally agree. That’s all it would take - a 20 minute delay if it’s too hot. They could even do it with software if they don’t want to add a thermometer - I.e if it’s been running on max over so many minutes, then add the delay.
the worst is that you often cant even buy new accus from dyson because they have none in sale for months. they rather offer you a replacement of the whole vacuum cleaner than delivering a new accu. 👀
Here's a idea, Why not stick to old school vacuum cleaners? At least you are not worrying about battery problems and then how to dispose of the lithium battery afterwards.
Because they are crap. The first time you use your Dyson stick vaccum it will make you SO HAPPY you will never go back. The negatives mentioned here are so worth the pure joy of these machines you will only know once you get one.... 💖
So sad. My tineco s12 battery is not working anymore. Both battery. I use on the max setting all the time. It only 6 months the battery is dead. The problem with cordless vacuum is the battery. So sad I can’t find the replacement battery for s12.
I bought a new Dyson V10. One of the attachments is defective. I called Dyson's Customer support. Their response was, "Not our problem. Go to the Seller." What???
This video answered all my questions
I bought my V10 7 months ago and it stopped dead yesterday. Dyson are sending me a new battery as they think that is the fault. I use it, of course i do, but there is just two of us in the house and summertime we are away a lot. I wouldn't say it has had excessive use. Also it is not fixed to the charger, I don't have room, so I charge it at the plug as and when. I had a Fluffy before which gave years of service with the one battery. Disappointed with this now.
Makita have a sensor for battery temperature which will shut down the battery or prevent charging while hot, surely dyson should be able to do this. Probably don't want to show up the limitations of the machine. My V7 battery has started to fail ( a bit too soon in my opinion) and I will be doing the makita battery mod when it fails completely. Then I can swap out batteries when needed with a battery system I already use.
Is there a way to restore life in the battery or once it’s stopped charging is that it? Replacement only option? Wish I’d kept my Henry, best hoover I’ve ever had, cheaper, simpler & just as good, no bells,whistles or fancy lights but it did what it’s supposed to Hoover up stuff.
Lithium cells have a limited amount of cycles, reduced greatly by deep discharge cycles (100%-0%). Unlike NiMh tech from a decade ago where batteries can be "trained" back to full capacity there's no proper way to revive lithium cells. Once they drop below a certain voltage the Battery Management System will stop any current from entering the system as there's a risk of fire. Best tip for longevity is keeping between 80% and 50% charge but this is not so easy to do with a hoover
very help video.... i learnt about fast vs slow charging when i was a kid playing RC cars
I did with power tools lol
Ahhh yes, trickle charge ftw
Outs just started acting up (press MAX it shuts off) so I bought a cheapo replacement battery off e-bay. So far it’s like new again for $50. Maybe we got lucky.
Mine failed at3 months 5 days.
Dyson had to change the design on the battery box. For example, Bosch has a cooling profile on the battery box on later models which means that the cells cool faster. Even the older Bosch Batteries without special cooling hold up well. I have a Bosch 18v battery from 2009 - which still works. I do not know why Bosch battery lasts so well. I use them for tools and garden tools. I'm disappointed with Dyson batteries. The first vacuum cleaner which only had 1 speed and 6 min operating time, lasted 5 years which was actually ok. So I bought a Dyson V6 and the battery is 3 years old and is at 40% capacity. I know how to make the most of the life of these Li-ion cells, but if they are poorly made cells you can not do much to make them last long. I'm glad I do not have an electric car, the cells are not good enough and too dangerous for cars I mean.
Yeah it's all very interesting. Funnily enough I had a Bosh Athlet before the Dyson and we had about 4 or 5 engineer visits in the 2 year warrantee period. Eventually worked quite well and my parents still use it, but I'm not sure what I think about using the customers as quality control!
Yeah, cooling is not as big of the issue as the fact that in dyson v6 and probably still in dyson v11 also they don't use battery balancing, if bms doesn't balance cells then batteries will die pretty fast as we could have seen all those years...
@@ftt2757 Tanks for your replay. A little strange, even Tesla cars cool cells down in hot climates and vice versa. Bosch batteries (li-ion 18 v green serie) are also not balanced and last for many more years, that is my experience.
@@sbromose1 maybe the are not balanced but they don't have bms that checks is they are ballanced, and also what is the wattage used by those batteries per cell ? And i know at least few batteries for powertools that don't have battery cell balancing or even bms in the battery but in those cases they have cell balancing in charger, and power cutoff in powertool
1:14. It is true for any manufacturer, that constant max or boost mode will kill a lithium ion battery. They're not back peddling. This is true. Compare it to a car. It has the option to run at wide open throttle and speed down the highway. Is constant wide open throttle good for the vehicle. No!! Other thing is you have heavy carpet. Thats another thing. You don't clean a whole carpet on boost mode. Boost mode is for quick deep cleans 5 minutes tops without the motorized brush head. ( vacuum operated turbohead). Lots of resistance develops on carpet cleaning in boost mode which creates heat. This in turn creates strain on the battery. I've seen people with Dysons that under normal use still work great to this day. The fault lies with owner operator of the equipment. It's lithium ion batteries that pose issues not the machine. Also every so often the cyclone canister should be serviced. You wouldn't believe how much fine dust and dander can gather outside the cyclone compartment due to static cling. ( the only issue I have with these vacuums, they need to engineer an anti-static cyclone system so that fine dust doesn't accumulate and pathogens congregate. It would be wise that they put UV sterilize technology in the canister). There are youtubers out there the circumvent the BMS ( battery management system) by taking the pack apart or jobbers that make adapters for Dewalt or Milwaukee batteries which is a ticking time bomb ready to happen because it bypasses the BMS code system and can pose a fire hazard. If in doubt it's better to be corded. But proper maintenance starts with the owner/operator. I've picked up a lot of cordless Dysons for chump change because of simple maintenance neglect and improper use and they work fine. I find that boost mode is a fad, because on my anemometer you only gain 5cfm of vacuum and a slightly faster spinning motorized brush bar. Regular mode is just fine. Don't use it in vehicles that are heavily soiled. Use a shop vac.
Totally agree! Still love the machine and it’s still going strong on its second battery.
My v10 battery also died after 2 years and I rarely if ever used the boost mode!
Mine died too. I used it for 5 times. I use Mid speed. I only use it once every 4 months. Cleaning cobwebs on the ceiling.
Interesting - actually wonder if that low use-case might have caused failure too - batteries don't link going into very low states of charge.
my dyson 360 eye ran for 5 years. then the accu was down. i send the robot to repair but they were unable to. reason unknown. replacement accus are not available for months now. they wanted to send me a replacement accu for the new dyson 360 heurist that runs out of power after 30 min only. again no accus agailable and they offer the replacement of the whole robot ...
awesome video, many thanks
Very helpful tips. Just got the v11 today. Unfortunately it does not have the swappable option.
Do not charge it full unless you want to start cleaning soon. A maximum charge of maybe 75 % will help your accu to feel more comfortable for a long period of time. 🙂
There is a design fault, have a battery with all cells in good condition also under load, but the bms keeps giving faults. Hope EU is going to give Dyson a huge fine as they did with Apple.
Yeah I had it fail after one year too. Dyson likes to tout that they are the best.
Same issue the other massive issue is changing the battery
I have the same issue, how do I get new battery fir free
So your saying not to use boost mode for more than one minute with a one minute rest in between and then also waiting 5 minutes before plugging it in after using the vacuum? You would think Dyson could put a temp sensor in the battery to prevent charging until it reached the correct temp!!!
Yeah it should really delay it’s charge automatically.
It's s common problem. I can't believe that Mr Dyson claims 15 years and people believe this nonsense. They claim these are as powerful as a full size machine, BUT it's only when on Max mode! For only 7 minutes.
Yeah the 15 year thing is a bit of a joke. I assume the little basis he had for that comment must have been if you don't use max power at all!
I'm Brazilian I have a V7 and the battery died in years and a half... I don't like wireless devices I like connecting to ac does anyone know how I can make extensions and use my v7 connected to ac? sorry my bad google english, kkkkk thanks.
I think Dyson pulling the plug on corded machines is a bad idea. Now with the lithium ion issue of not being shipped and kyboshed to many countries for battery development. Apparently shortages of lithium ion batteries are becoming an issue. If anything, he should go hybrid on his vacuums. Going to be a lot of disappointed customers.
18 months is good when I bought Roy dyson v8 animal it came with dead battery so after so much argument they changed my vacuum and send me a v10 . So it worked until I had to charge it. Well it did not charge again so once again I am waiting for them to send me this time the batery
Dyson's battery vacuums have been plagued with poor lifetime for years. My brother had one of their first hand vac's several years ago, and it died in six months. Dyson sent him a new battery and that died even faster. He never got another one.
I thought it was only the v11 you could change the battery? I heard the v10 the battery is inbuilt and can't change it which is one of the benifits of buying the V11?
You can change it, just not easily. Needs a screwdriver. 5 min job.
Opened my v11 last night and let the battery fully charged... tried to use it this morning and the battery is a dud ☹️ I was really looking forward to using it!! Waiting for a replacement battery now 😅
What a pain! Hope replacement is good!
Same thing just happened to me. New machine and was dead on arrival. I did online order, 15 days before we get a new one in the mail. Lots of money to just sit around waiting in parts.
I would have used a system where the battery slides on the side of the Dyson, charging on a remote base station similar to the ones on power tools and having a spare battery when the other one runs down . Doing all these things so your vacuum cleaner can work so you can clean is unacceptable for the cost of this product and thank God Dyson didn't continue his dream electric car because we would have to bear another disaster of a design.
Yeah it'd an appealing idea in some ways for sure- although it does mean another charger kicking around. In principle if the batteries last a reasonable length of time I can make my peace with the compactness and ease of using a 'dock' type charger. I want a good two years from the battery though.
Yes, I’m sick of Dyson’s greed now. I am regularly replacing battery’s for two cordless vacuums that I own (every 2 years or so). I am I no doubt that the battery destroying itself when it is charged when hot is part of Dyson’s planned obsolescence algorithm. To modify the battery to delay charging until it cools would be so simple. All the hardware, including temperature monitoring and processor are already incorporated into the battery. it would just require a software modification I’m sure. But that isn’t in the interest of a moneymaking company is it?
It just happend to us, In Australia
Thanks. I'll stick with my corded vacuum for now.
Ha yeah I still easily think it’s worth it. It’s still going strong and has amazing convenience. Still on that second battery, no issues apart from needing filters replacing a few times.
I v10 died last week. Just stopped working all together.
Inside warranty or not?
@@BenVallack outside of warranty.
How's your V10 doing? I'm planning on buying one and just curious for an update. Thanks
Was thinking of doing an update soon actually. It’s still in daily use. Still on the same second battery. Have gone through a few filters and I did replace the trigger (not a quick or easy job but it benefited from removal of a lot of collected dust inside at the same time). Otherwise no other issues. I’m pretty pleased overall considering the abuse it gets. It’s a shame about the trigger failing and how hard they make replacing it. Still great performance and usability though!
@@BenVallack Thanks for the update. I just ordered one today…and hopefully it will last me for a while 🤞🏻.
Had a Dyson, used once-twice a week max, terrible product and customer service, warranty is useless
Mine is still going strong - amazing thing- it probably will be needing its third battery soon but I’m not too bothered by that given the performance.
If they will not send me new battery, can I just replace the cells in old one ?
YES YOU CAN , but need some tools ~ Recommend you buy the cell online and find a electric fixing shop to help you change the cells
The v11 , the carpet attatchment stopped working after a few uses. Lightly used only.!!
They have no tech support.
My filter light would not reset. I finally removed the battery, cleaned the filter and it reset and started working again. I can use it , but not the carpet attatchment.. I paid like $450 at Best Buy. Very expensive, will never recommend this vaccuem !!
15yrs!! What a joke! I’m on the 3rd battery in 3 yrs!! 😡. And we might use it once a week. ***Im about to design a power supply for mine so I can use it more than 5-10min.
When our V10 dies, we naturally return it immediately to the charger. Sounds like doing that shortens the battery life.
-> We have another wireless vacuum cleaner that will run for more than 30 minutes on one charge. It’s also a powerful vacuum, so with the right battery it should last longer.
My battery is about 18 months old, and seems ok, but when fully charged it flashes red/blue, Dyson support don't have a clue what it is
Woah crazy!
Update -Dyson UK sent first a new battery and then a new charger, this seemed to fix it.
Glad it's resolved!!
Happened to me too.
Happened to my V10 too. Terrible product.
Dyson vacuums suck. Im done with them.
Same here …. They are expensive, need a lot of care … bad battery
Pretty much all batteries fail. The dirty truth they never tell us.
Let's hope the Tesla we just got fares better!
@@BenVallack trade it in right before the warranty expires.
@@rebellucy5610 Heh yeah, luckily that is 8 years away!
Yes that happened to me.
The new Miele Triflex is the new competition. More sturdy and excellent performance with user changeable battery and ability to stand up on its own!
Oh really! I’ll check it out.
At first glance my thoughts are that it doesn’t have a fluffy head, or a mini motor head. Both of those are key reasons why the dyson design is so good in my opinion. Would love to give the Miele a good test in real life though.
Ah looks like it does have a small motorised head. Certainly looks like an interesting option.
Case closed. Miele is 1kg heavier than the V10. And about £100 more too. So far I’ll stand by my ‘no competition’ comment ;)
My thoughts ...If Dyson wanted to produce a really excellent product ...Mr Dyson..ought to look at air cooled chargers, like Metabo or Bosch use ...for their power tools ... supplying a couple of batteries, stops the one battery being precious ...The Sony cells inside the one battery are not custom cells, there off the shelf .. standard cells ... charging bigger more powerful Metabo batteries ...takes 40 minutes max..a Dyson 7 cell maybe 25 minutes, helped by fan cooling ...
Mr Dyson is far behind, with his charging and Battery technology...their move to click and go battery’s on new generation v11 is good news, battery’s are however expensive, charger is slow, and will not elongate life span ... very basic slow charging...however Dyson is still the leader...watch out a Chinatown man could see opportunity...Tesla or Metabo could make a better model ...maybe ... ric
It's good your using your brain to do all these things. To me it sounds stupid that you have to do this for an expensive vac.
Yes and no - the reality is if I changed it every 2 years it would never be an issue due to warranty - but that’s expensive. I’m happy to pay a certain amount for the convenience it offers but not that much! My little ‘hack’ should let me keep the super cool technology for long enough to ensure it doesn’t end up costing too much overall. :)
very helpful. thank you
Most welcome!
How long do you think the V10 animal will last if you do all the steps to make sure it doesn’t die fail that fast? I’m looking for a vacuum that can last for at least a few years before replacing it since I think cordless vacuums still have a lot to improve on.
Considering I had been charging it directly after full depletion I think if you avoided that then the 2 years would be easily achievable- but the warranty covered the repayment anyway so you’ll definitely get the two years service (unless they change their position on replacing them!). What I keep thinking about the v10 though is actually how good it is as a full household vacuum - it absolutely replaces any corded machine for us in our 3 bedroom semi-detached. I was anticipating needing to upgrade due to the technology potentially not being good enough to make the concept work properly etc - but I actually don’t feel the need to upgrade to the v11 at all!
@@BenVallack Alright thanks for the info but I don’t think it would’ve been that much of a hassle for them to add a system that detects whenever the battery is cool enough to start charging. That’s the only thing that really bugs me. When I finish vacuuming, I just wanna sit down, relax and not have to worry about when I have to charge it.
@@marsbars4767 yeah definitely agree. Having said that normal day to day use gets no where near empty. The medium power mode is genuinely good enough so the ‘little and often’ approach at that level doesn’t use up all the power so it would be fine to just chuck back on the dock. That said the Ikea hack does also work well when needed!
@@BenVallack 👍
@@BenVallack Having some trouble deciding between the Dyson multi floor 2 and V10. I have quite a few dogs that bring in a lot of debris like dirt and pet hair that’s mostly on carpet so I need a decent deep cleaning vacuum too. Do you think the V10 will still be enough?
Junk. Not worth the money. Underpowered and disappointing battery life.
Worth every penny, more power than I ever need, can’t remeber the last time it ran out on me 😉
Mine lasted 3 years. If you buy one that has been on the shelf it may not last that long. However, replacement batteries, even 3rd party ones are available, easy to install, and not expensive. So a non issue really.
agree - small price to pay really!
Mine lasted 2 years. So who is 3rd. party?
@@MH-dj5im This one worked for me: www.amazon.com/dp/B0822NYHK4
Money out of pocket IS the issue.
Dyson cordless vacuum batteries are garbage!!.. Do not last longer than the 2 year warranty!!.. Buyer Beware!!
Dyson company just scumers for me.
Yeah I don’t really buy this narrative. They make good products that are expensive. They also offer excellent tech support too. They’re definitely a large greedy corporation with a very creative marketing department but after that I don’t think there’s anything fishy going on.
It’s disgusting that they’re making the batteries like this. I have an 11 year old Tesla and it’s still fine. They’re making these to fail on purpose. Dyson pride themselves on design, but have done a terrible job in terms of battery management. The fact you need to do all this crap with wireless apps an chargers. It’s ridiculous. Also crap design that the batteries aren’t interchangeable. So disappointed in Dyson. 😢
The only solution to the Dyson Battery problem is Dont buy one,they are a heap of Junk.
Don’t buy dyson, same problem
Funnily enough I still wouldn’t have anything else. Mine is still going strong on its second battery now I’m a bit more aware of the battery management.
Dyson doesn't care about customers. You paid for the Dyson that's all they care about.
Actually within warranty they were very good. Also they were very good when I had issues with my fans too. This is still our daily vacuum cleaner by the way, and still going strong on the second battery!
Yep my battery died month after warranty expired. Couldn't even give me 10% off of new battery so I trashed and binned it and bought bosch. Dyson was way more ergonomic and better to use but shitty service sucks.
@@tapio83 Yea.....fighting with Dyson replace my battery under warranty.
