Sorry, I know I won't, as it's "welded", I meant on the other traces, I'll be quick and delicate, trying to protect the cells.
No one has tried to pry it. That was bent during removal of the battery or during unfolding (the pcb is folded into the cells and in on themselves).
As said, a simple "oh, PCB on one side, cells with wires on the other", as I've seen in other tabs (dead so sacrificial attempts!
), was shown to obviously be an old design. Same with phones, I never really offer to repair those, as the good old days of screws are simple repairs are gone to glue and extremely dense boards (see the iPhone X for amazing tech, but a nightmare for repair).
I only do part swapping for PCs. Soldering for hobby stuff. But as this has been explained to not be too taxing, I'll give it a go. Some pencil wire and .4mm wire on order for the next couple of days, at 1/4 the price the local Maplin would have charged without delivery on top.
