Calculating time to full battery recharge

I need a little help calculating how long it would take to charge the battery pack of an electric vehicle with the following parameters:

The vehicle has six 12-volt flooded electrolyte batteries, and an on-board 72-volt DC charger that plugs into a standard 110-volt AC 15-amp outlet.

The manufacturer of this particularly odious Neighborhood electric vehicle (they're all a little odious) doesn't mention the time to full charge in its published specs- a rather telling omission, I think.

This question is already asked on the Science Desk. Please don't post the same question on multiple desks. Rkr1991 (talk) 11:15, 9 July 2009 (UTC)
