if the machine requires 260A and if i take a battery of 1300Ah, it would mean that the battery is discharging at 1300 Amps per hour so if the machine takes 260 Amps then what happens to the rest of the current.

the motor takes 260Amps so does it mean that it will take total 260 Amps as long as it is on ? so 260Amps for 5 working hours also and may be 260 Amps for 8 woking hours also? please help me solve my confusion

No.

1300Ah is the capacity of the battery. Simplifying, it could provide 1300A during 1 hour or 260A during 5 hours. However, the battery capacity is given for a certain constant discharge current at a certain temperature. It's explained here: http://en.wikipedia.org/wiki/Battery_(electricity)#Battery_capacity_and_discharging

The rest of the current doesn't flow. The battery does not force 1300 amps through the motor. The motor only takes what it needs.
