Black & Decker - Dust Buster: battery replacement

September 21,2024

Recently I got a hand vacuum cleaner for free. Why? Of course: the battery pack is dead. I don't want to throw it away, so I'm going to replace the internal battery pack with replaceable 18650 LiIon cells. The modification consists of: * removing old battery * replacing the the cells with 2x 18650 cells and a balancer circuit * replacing the original charger with a USB step-up 2S charger

This vacuum battery is a replacement for the Black & Decker 90584779 and all compatible models listed below. It is made with high-quality cells and meets or exceeds the original manufacturer's specifications.
