APC and battery?

You should not parallel it to the original battery since they are not the same type. You might get away with replacing it though but the charging time and characteristics can be a problem. The charger inside the APC is not set/dimensioned for a car battery and the car battery is usually not of the deep cycle type. A starter battery (car battery) is constructed to supply very high current outputs for short periods and not to be deeply discharged. The deep cycle type cannot supply such high currents but will allow you to drain it down to 20 or 30% before you charge it. 
If charged from an external source it would work and add some extra time. Correctly setup and fused there should be no additional risk of fire. However the car battery will not cycle as many times as a deep cycle type battery would before the end of its lifespan.
