Hello and welcome to just answer and allowing me to assist you. we have run into that a few times but not to worry they are inexpensive to replace if it goes that far. try soaking over night with wd-40 penetration oil or vinegar. If that doesn't work then use side cutters to ct the end off which you can replace easily with a crimp on on don't solder as it will melt the link. Never use heat or open flame near the battery as it can explode. Hope this helps your problem and if you require further assistance I 'll be happy to do so.

you can try using a small metal saw on the nut just don't use any thing that would create sparks .
