I'm gonna guess repairing the battery terminal with solder, wrench to deflect or concentrate heat.
Winner winner! While my bike ran without a battery in circuit, I didn't have a DC system. This meant I didn't have a fan, lights, starter and as important as the fan, I could not charge my GPS on my bars.
I'm happy to say that the repair worked for half a day, until I accidentally hit the starter button with the bike in gear. I then pulled in the clutch and hit it again too quickly. I believe I melted my solder job and the battery failed again. I was balancing a good solder job with melting or exploding the battery.
In the end I was lucky enough to be able to purchase a brand new lightweight battery from a guy on an Alexander Smith No Whips Ride.
With pictures and explanation "Battery Stuff " issued me a complete refund even without the battery. I left it in Cativina.
