Why not just store it safely, in case you need some more later.I don't know why but they say to never use it to top off a battery, only add water so I'm not sure what you could use it for.

After reading this:
Concentrated sulfuric acid is frequently the major ingredient in acidic drain cleaners which are used to remove grease, hair, tissue paper, etc.So, each time I flushed the can I'd squirt a tablespoon or so in till it was gone.
