Why won't my DustBuster hold a charge?? - Vacuums

If less than about 12 months could be the charger, if older than 18 months or so it could be a dud battery

Does the charge light come on when you plug in the charger? If not, the charger or cord is probably bad. If it seems to charge but you're not getting as much time as you used to, the battery probably needs to be replaced. Check your warranty and call dustbuster or go online to purchase a new battery. Another alternative, especially if it is out of warranty is to take the unit to a Batteries Plus store and have them replace the battery.

Either the battery pack needs replaced or the charger is not working correctly.

Did you check a dust bag for full of greaze?

I had the same issue, then i just found the manual, in charging part, it says:"The charging indicator will be lit as long as the
appliance is connected to the plugged-in
charger."
Also it says:"While charging, the charger may get warm, this is
perfectly normal and safe. It can remain on
charge indefinitely without damage or danger. It
is not possible to "overcharge" the battery cells
with the charger provided"

You can test the output of the charger with a multimeter. Set it at about the 20v scale and touch the contacts at point where it connects with the Dustbuster. If you get a reading it means that the charger is working. I would say that the charger is most likely not working because LED indicators very seldom fail while chargers are not all that reliable.

Yes the battery is most probably the problem. you can check is the voltage of the fully charge battery is same as what is stated on it, if not you definitely need a new battery

If the battery is nicad they will not tolerate leaving on charger past full charge.

if its not working at all it has a fault that could be anywere if it is working but with little suction then the batery is no good replace the battery

Leave it in the charger for at least 7 hours and then try and see if it works on a full performance time of roughly 3 minutes.
