The listings on 3rd party batteries like at NewEgg (
HQRP Battery for Dyson DC31 DC34 DC35 DC44 DC45 DC56 Series plus HQRP... ), Ebay (
NEW DYSON DC44 DC45 VACUUM Battery Type 2000Mah CORDLESS DC34 DC35 4402B ), and others lump the battery for the DC44 and DC45 together, so you're probably fine.

You may want to take the battery to a Batteries Plus or such - sometimes a battery will show voltage just fine, but choke once there's a load on it. They have the gear to tell (same as with car batteries)

Good Luck

SOURCE: power head

If you have checked the power delivery down to the powerhead and you have current running to the powerhead, then you likely have a burned fuse. There is a fuse built into the powerhead motor and is usually located on the field winding. This is not easy for a novice to replace and even most professional repair shops will replace the motor. It is possible to replace the fuse if you know what you're doing, but if the fuse blew, there may be a more serious problem, after all, the fuse is there if the motor starts to experience distress and the fuse will blow to avoid any electrical issues. The fuse can blow if something is jammed into the roller and causes the motor to labor heavily. If this is the case, then the fuse can be replaced safely. If the motor is burning out, then a new fuse will just blow immediately after replacement. What I do is take the fuse out and run the motor without it to see if the motor is still viable and replace the fuse if the motor proves to be o.k.

    SOURCE: I put a new battery

    Hi there,

    Sorry to hear you're having difficulties with your DC16. Although your cleaner will no longer be under its original 2 year warranty, the new motor assembly would be covered by a 12 month warranty if you purchased it directly from Dyson. As long as the cleaner has been used in accordance with the terms and conditions described in the manual, we should be able to replace this for you.

    Alternatively, we could arrange to have the cleaner returned to us for further inspection.

    In either case, please get in touch with us directly so we can discuss the issue further. You can call us free on 08002980298 - our Helpline is open from 7am until 10pm, 7 days a week. We look forward to hearing from you.

    Kind regards,

    Dyson Customer Service

    How can i test the power switch on my Hoover Windtunnel bag less upright that just stopped working suddenly? I have a multi tester but don't know how to use it.

    With unit disconnected from all power connect the multi tester to the two terminals on switch after putting the tester in the resistance mode. Flick the switch and see if you get continuity and break continuity condition. If you do the switch is good and your issue is elsewhere.

    Can I leave the battery charger plugged in my Dyson dc 44 animal after it is fully charged?

    Hi, I have a Dyson DC56 with a lithium battery for about 18 months and I leave it plugged into it's charger when not in use. I do notice the Dyson charger seems to switch off automatically when charged. I don't have any problems so far. It you have a Genuine Dyson Lithium battery and the genuine Dyson charger it should not be a problem. That is because Lithium batteries have very precise requirements for their charging cycles and therefore the correctly designed charger required to make them work safely is a somewhat intelligent design and needs to be of good quality in having to meet those requirements. So use the original Dyson Charger. Also most high current Lithium Batteries will also have a protection circuit built in further increasing safety and reliability. Just don't use cheap cloned Chinese made Lithium chargers, because you will never know if they have been designed or even will operate correctly.
    Now if you have old technology Ni Cad (Nickel Cadmium), LA (Lead acid) or NiMH batteries with basic cheap chargers they should not really be left connected to a charger full time.

    Dyson will not start

    If the power cells are operational and it will not start; then either the motor is dysfunctional or something is jammed in the intake module. A conduction test with instrumentation can indicate if the motor is the problem, the power cells are not fully charged, or you have a short circuit. Check Fuses.

    Why won't my Dyson DC44 rechargeable vacuum brush attachment not work or pick up anything?

    Hi Kim, it's Jack at Dyson.

    If your DC44's motorised cleaner head doesn't seem to be picking up as well as it should be, it sounds as if there is a blockage somewhere. To check for this, please follow the steps shown in our Support guide:

    The video I've attached should also help you check for and remove any threads, hair or debris caught around the brush bar.

    If you'd like further help after you've given this a try, please get in touch with us directly so our experts can talk you through some additional troubleshooting checks. You can reach the Dyson customer Helpline on 0800 298 0298 (UK), 1-866-693-9766 (US), or 1800 239 766 (AU).

    The battery itself is need to be check for that. If you charge it for long time and still doesn't charge then the battery is defective. Be sure to replace it with the same type and ratings. Another way to test it is by using a digital tester. Set tester to DC range and point test probe to it's positive and negative terminal. If it measure below its indicated voltage it is defective and need to replace.
    Thanks for asking

    My Breville portable vaccum cleaner BHV9 stopped working. I haven't used it for the last 1 year. is it the battery?

    good day..
    try to see the LED indicator of your vacuum if it is light to low battery charge it...if the indicator is not lights-up your battery is drain.. because when the battery is not used for the long time it is got drain.
    try to remove the battery and test it using tester the reading of your tester must 12vdc if not or almost zero reading replace it

    if the indicator is on normal lights so your battery is good and the motor is not function..
    try to lubricate it with the oil to the bushing

    thank you and good luck
