Flyco clipper battery died, replaced with a portable spot welder. Dug an old-stock Flyco clipper out of the warehouse, battery gone, needed new cells; none of the flat-top cells I bought reached 400 capacity, so I had to buy button-top, which have plenty — fitted them, and it now runs twice as long as new. The portable spot welder works great too, welds very solid02:42

Swapping a flashlight battery with a handheld mini Li-ion spot welder. The handheld mini welder is easy to carry and works for re-celling power banks, players and other small gadgets. Solder a Li-ion cell with an iron and the heat raises the pressure inside and can ruin the cell — only a spot welder will do05:59
