How is it broken? Is it a bolt-on terminal and broken across the eye? There are no hard and fast rules for this stuff, perhaps posting a pic might help.
Stegerman MotoOCD sufferer
Its not a bolt on to the battery. But the cables do bolt through an eye and the eye broke. I am no opposed to dropping 69 but Im a CBOA at heart so heres what I did. JB Weld around the outside of the terminal after softly pounding the two pieces back together. Then I'll run thin copper through to help the conducive properties. Pictures will follow.

I also have a battery that broke the post really close to where it goes into the battery. Drilled it the size of the smallest allen head I could find. Then took a small plate I drilled and bolted at a 90 degree angle to the old post so there would be less torque on the bolt hole. Bolted it tight, and liquid steeled it for additional strength.
Stegerman MotoOCD sufferer
Battery was about 1 yr old and very strong. Took it to a battery specialty shop. Guy happened to also be a BMW owner. he didnt have anything in stock, but he filed, tapped it and I dropped a wood screw in when I got home. It's a very solid connection. I will prob buy new this winter, but for now I'm satisfidd.
