with the fact that current is reponsible for the damage, I've heard that 1.5V batteries can deliver infinite current, if its true then why it does not harms a human body.
OR
The power is a danger to human. current * volt.

1.5 volts is less then rubbing your feet on carpet in socks and touching metal. It is DC current anyway and almost no amperage and no they can not deliver infinite current. Once they are exhausted thats it your in the dark.

Current
(Symbol I), measured in Amperes (Amps, A), current is the rate of flow of charge, as carried by the charge carriers (see later.)
Metal, due to it's structure, has a cubic lattice of atoms and a pool of free electrons surrounding them. In metal, these electrons (charge = -1) move to produce the flow of electric current. In an ionic solution, the ions move to form the current when electricity is passed through the solution. This is called electrolysis. In semiconductors, both electrons and holes move to create the current. N-semiconductors have more electrons, p-semiconductors have more holes. When two differently doped pieces of semiconductor are put together (NP junction) this forms a diode. Then three are put together (NPN or PNP) a transistor is formed.
A current is the rate of flow of charge. Charge is measured in coulombs(C) and has the symbol Q. The equation connecting the three quantities is:
Current = charge / time (I=Qt-1).
Q = coulombs. I = Amperes t = seconds
Doing this can be confusing when different orders of magnitude are used. e.g.
1. 50mC flows in 10s. What is the current?
I==5mA
2. 50uA flows for 1 minute. What charge has flowed in this time?
For a 1.5V battery, the maximum current is 140mA with an internal resistor of 1.25ohm. You may experience the shock, but not harmful enough to kill you.

You're right, it is current that can kill a person. However, it takes a lot more current than you can generate from a 1.5 volt battery to do it. A standard 120-volt line in a house with enough current going through it can kill you. Ditto that for a 220-volt line like they have in Europe. Double-ditto that for a car battery (it's only 12 volts but they average 50,000 amps or more).
P.S.: It's not true that a 1.5 volt battery can generate infinite current -- nothing can.

Human body has huge resistance. Current can not flow at the 1.5V.
And current from battery cell is not infinite, the battery itself has internal resistance also.

Amperage is dangerous not voltage .A 1.5 V battery Does not have enought amperage to be a danger to humans .
