solder nicd
Hi
I agree with flatulent it is possible to solder batteries, just remember to use a soldering iron with enough wattage, you do not have time to heat it for a minute or so. You need to be quick and use a lot of heat just as flatulent said. BUT remember that batteries can explode so if you would like to be on the safe side and be able to see Santa use eye protection. I do not know if it is neceserry, I have glasses so I trust they will stop the most if the batteries explode.
Good luck
