Swapping flashlight/shaver batteries with a handheld

Repairing a Philips shaver with a new battery so it lasts another 10 years. After years of use it died a few minutes after charging; now with a higher-capacity cell it runs twice as long as new

Repairing a Boda cordless drill: new Li-ion cells, spot-welded pack assembly. A friend was about to throw out a dead drill — both batteries dead, the drill dead too, only the charger worked. I fixed it, so I’m not giving it back, I’ll use it myself

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 solid
