Unsolder it. There shouldn't be any problems. Take the battery to a
battery rebuilder and they're make new tabs from strap stock or they will
pull the ones off the old battery cell and spot weld them to a new one.
Solder the new battery back onto the board and you're back in business.
I've done or had done a couple of dozen of them and never had a problem.
Three things will make all the differnece in the world (1) use a decent
temperature controlled solder iron (I use an inexpensive Weller) and (2)
use GOOD fresh solder. Throw away ANY from Radio Shack or any that is dull
looking (oxidized) (3) clean all the surfaces to be soldered till they are
clean and bright. I use 2% silver solder made by Kester and it works GREAT!
It also melts at about 500 degrees so you can turn your iron temperature
down and that helps prevent damaging circuit boards and components. If you
have trouble finding any let me know and I'll send you some.
