A quick look at the battery in a 500VA APC UPS - 12v 7AH. At full load, this gives me a 2 minutes, or 14 minutes at half load. A typical car (or motorcycle) battery would extend these times considerably.. Car batteries can deliver in excess of 350A for very short periods.
But you'd have to be sure the charging circuit can without burning out deliver the current the larger accumulator will draw.
