Repairing battery contact plates

Hi all, I've a perfectly good battery but one of the contacts is bent and a bit split from over tightening. Anybody know if they can be repaired? I was hoping they would be made from lead and therefore fixable with a lighter but that doesnt seem to be the case. I think this is likely the source of my electrical gremlin as I have it stuck on with a vice-grip atm and it seems to have fixed it. 3 weeks since last I rode . And need to get other things sorted in time for the track day...

Can you put up a pic - may be a help.

Beware of the Hydrogen gas in the battery

go to a auto battery place or auto electric and they can repair it ,,,,have done this many times with auto batteries
