I've soldered probably 300-350 cells, from AAA to D, and never had a problem. Preparation and a high-heat-capacity iron is the key. The correct flux also helps a lot. I use Lonco CF430 and it makes a huge difference, the solder runs like water. I can always touch the cell without any pain, just as soon as I can put the iron back in it's stand, so nothing in the cell is getting very hot.
