My experience from trying to make solder connections on ni-cad AA batteries is that after soldering the batteries will only last a short time. They seem to be OK for a little while, but even it you are trying to rebuild a battery pack with new cells soldering damages them so badly that they don't last. I like the suggestion from przemek if you are trying to reuse old cells. Otherwise you need a small spot welder like one from the Instructables I have seen in the past.
