Dustbusters have been dying an early programed death for decades now, going back to the NiCad battery days at least. Please don't buy another one.

- Battery charging
- Charger sees increased resistance when the battery is full, then disengages charging to prevent an overcharge explosion.
- The system sits. The battery naturally discharges slightly.
- Charger sees reduced resistance, then engages charging.
- Repeat.
What this shitty battery charger is doing is repeatedly cycling the rechargeable battery. That decreases capacity. The consequences are far worse for cheaper nickel cadmium batteries (often paired with shitty battery chargers) than lithium ion batteries (often paired with chargers that turn off once the battery is charged).
There's two solutions: Buy cheap and unplug it when it's charged; Buy a nicer product that'll do it for you.
Example: Walmart burner phone vs. basically anything else. Leave the burner plugged in overnight for a week and it's dead because the battery chargers are trash.
if there was more people here someone would have recommended a Dyson not knowing what their talking about.
