I have two B&D 20v vacuum cleaners. Both of them worked exactly 1 year and then had the same issue: work only for 15-30 seconds then are switching off. There are multiples reviews on Amazon about the same problem, thus I think it is worth to try to fix or at least find what the problems it.

The battery pack is soldered to the controller, thus there is no easy way to replace any cell.

How should I start? I do have a multimeter but do not have oscilloscope…
