Hi there, it's Jack at Dyson.

I'm sorry to hear you're having difficulty charging your DC44. We're unable to specify an exact lifespan for the battery as this will depend on how each individual machine is used and maintained. But we would expect the battery to last for at least the 2-year guarantee period in normal use.

When you have your machine easily to hand, I would encourage you to get in touch with us directly so our experts can talk you through some diagnostic checks to help us confirm which part is at fault. If a replacement part is needed, we can also check that this is covered under your 2-year Dyson guarantee.

You can reach us by calling 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU). We'll look forward to speaking with you.

SOURCE: Hello, what is the significance

yes the reason the green and red light were flashing the way they are is because its a warning to you that the battery is either no longer good or there is problems with your wireing. Also those vaccumes were designed to not charge when there to cold or to hot as a saftey issue.

    I have a Dyson vacuum cleaner cordless and is not charging the red light is blinking but there's no green light we have had it for about a year and a use it every day usually twice a day

    An issue with the battery may lead to the charger not detecting, nor attempting to charge the battery. I've solved this in the past by leaving things on charge for an extended period of time (sometimes days at a time, but with frequent checks that it's not getting too hot), but your mileage may vary.

    Worst case scenario, you may need a new battery or a new charger. You can buy cheap replacement chargers from China for under 10 dollars, but a battery may set you back more. I suggest buying a genuine Dyson battery if you can; a charger isn't as important to remain genuine.

    Definitely look into whether you're still covered by warranty, as I know Dyson offer some pretty hefty after sales support these days (some 5+ years). If you are, give them a call and see if they can help.

    Hi there, it's Jack at Dyson.

    I'm sorry to hear your DC35 is currently displaying a slow flashing light when you pull the trigger. In order to determine what's causing the issue, our experts would need to talk you through some simple diagnostic checks when you have your machine easily to hand.

    When it's convenient for you, please give the Dyson Customer Helpline a call on 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU). If a replacement part is needed, we'll also be able to confirm whether this is covered under your Dyson warranty.

    We'll look forward to speaking with you.

    Red light flashing constantly on dc16 when on charge, used to just stay permantly red without flashing until it went green when charged up.

    I had a similar problem when I bought an after market 2Ah battery. Would stay solid red for a few seconds then flash red. I believe my problem was that the battery had gone into "sleep mode" I.e. it was discharged to the point that it "sleeps" in order to protect itself. So......I simply attached a domestic DC multi adapter to the terminals on the battery that are marked + and - (the 2 outside terminals on a DC16 Dyson battery). Switched on the DC adapter for around 10mins and this was enough to "wake" the battery. It now charges as normal attached to the DC16 in the Dyson charge mount.

    For a pretty in depth article on lithium battery sleep have a look at this:
