Maybe if you had a solar panel on the roof that kept the battery topped off (and off-gassing) and had a way of collecting that while the vehicle sits (would be an explosion hazard.

I don't think it's enough to make that much of a difference though. Maybe if you had a DIY hybrid with a truck bed full of lead acid batteries it would help a tenth of a mile per gallon.
