[Request] Recommend Me a Dustbuster (dubvee.org)

I bought a Black and Decker dustbuster 2 years ago, and it was great for the first year. After that, it will only run for about 45 seconds and then dies. I've just kind of dealt with that, only using it for occasional small cleanups rather than actual use. The batteries are impossible to replace without also destroying the battery holder and circuitry (I tried).

Basically looking for a recommendation for a good dustbuster that sucks in the good way and, ideally, has batteries that can be replaced when they go bad.

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.
