Hi,

if you get a hobby knife(sharp) cut lines into the cells from everyway and then tip the cell and the battery bar before puting them on.

ANother way that you need not use your wife's or Gf's nail filer is to just use sand paper to sand away the thin layer of oxidised metal.

I've been preping all my cell this way for years...

I have to agree with this. I use a wire wheel and scuff just a bit, then tin the end using flux. The key is to use a hot iron with a large tip. You want to limit the amount of heat the cell get's exposed to. with the ends tinned and cells in the tray, put the bar over two ends, (Dean's jig is really nice cause it holds the bar in place), then apply heat and solder to the - or + hole. You want just enough to liquify the tinned solder. You'll end up with a strong low resistant joint.

i managed to buy a 80W "dosposable class" soldering iron from a local auto parts shop.

cost me $14 AUD and came with the normal sodler tip and a chisel type tip, which is perfect for soldering batteries.

the sodlering iron tips are not the greatest quality but i have managed maybe 20 packs out of an iron then use it for repairing plastics

waste not want not :P
