EGO CTwist (clone) broken wire repair

[UPDATE FEBRUARY 2017 - The fix below was done three years ago. The repaired battery ran fine with no issues until it gradually died, as all Egos do. Now we are in 2017. Egos are, these days, extremely cheap to buy. My strong recommendation is that if you damage your Ego battery you should throw it away and buy a new one. I'll leave the original post up for reference purposes only. D]

Well, this evening I've been mostly fixing this broken Ego CTwist (clone) battery. It was dropped, the end popped out, a wire broke off and there was a short which melted the plastic sheath on a couple of the wires. In particular, the green wire from the base of the battery was fried along its full length. The positive red wire from the top of the battery was also burnt. The wires themselves are extremely fine and I was unable to obtain a direct replacement. I therefore used the thinnest wire (7/0.2mm) I could find at Maplin. It was still about twice the O/D of the original stuff and refitting the battery into the tube was a bit of a squeeze, but it went in eventually. If you're still interested, the rotating dial on the base of the battery was a bit of a fiddle to remove but its only clipped in to place as you can see from the pictures. Finally, the actual battery has soldered tabs so replacing the wires simply involved soldering onto the tabs. If they'd have been soldered directly to the battery I would not have done the repair.

More soon, no doubt...
