Re: [OM] OK, I know I am inept, but.....

Yes, the surfaces to be soldered must be clean, but maybe you're not inept 
after all, just unlucky!
You can also have problems if the metal is not meant to be soldered - often 
rechargeables have stainless steel (or similar) tags that are intended to be 
spot welded...  In this case you'll see the solder form into a nice spherical 
glob that doesn't "wet"
the tag at all.  There's no simple answer, but you can try making a good 
mechanical joint between tags (crimp) and then try to get a solder blob to flow 
around the crimped tags enough so it holds the mechanical contact together.  
You could also use some
conductive epoxy (silver loaded - sold to repair heated rear screens in cars).  
You probably wish you never started, but I'm sure you'll get it fixed in the 
end - and with luck your only problems are the iron temperature and clean 
surfaces.
