Can you regenerate a dead power tool battery

I have seen this on youtube but didn't believe it. As I have two dead batteries I thought I would give it a go, nothing to loose! As it turned out, after the video the second one died again so both were still dead! Conclusion: It might work for some but not for me. #GaryHuston #Blacksmithing #Farrier #ASMR #Horseshoeing #Fabrication #Ironwork #Hoofcare #welder #repairs #horse #farriery #engineering
