Vanadium-tin battery. Would any acid work, or would it require a particular kind? Tin being a crumbly metal, that would probably be better with a weaker acid like citric or acetic acid (like from lemons or vinegar), instead of hydrochloric or sulfuric. But you never know.

The role of an acid in a battery is to act as a ion conductor and electron donor. How about using a oxidising agent instead? Like weak hydrogen peroxide.
