battery broke free and fell into engine bay, need help

[hunter_507]

so i was driving through some rough terrain and somehow my battery broke free... and it fell into the engine bay. the red plastic on the positive side was up against the manifold and melted to it. I didn't notice it till i went out to put my truck in the garage, and when i tried to start it it didn't make any noise at all when turning over, no clicking or anything. i'm guessing i'm gonna need a new battery, but is there anything else i should try before spending 100 bucks on a new one? i tried jump starting it after getting the battery back into place and nothing happened. any help would be great.
