But, I don't know how to measure the amps flowing into the battery. I can't able to know whether my battery is charging correctly or not. Can anyone help me i this regard.
Thanks

Meter plus to pin 5 and meter minus to pin 2.
What is R3 value in your circuit.
calculate R3 = 6-2 / 0.5 ::: R3 = 2 ohm?
it is not like that
measure the voltage across the pins 5 and 2 divide by the Value of resistor you use
In general, the V(5-2)means voltage difference between pins 5 and 2 and not voltage at pin5 -2
you can safely assume for a 2 watt or so resistor usedbetween pins 5 and 2, the voltage would be around 0.45V
thus Iout can be 0.45/R3
one datasheet indicates , in general the voltage across p5 and p2 is 0.45V. for 4 amps you can calculate
for current measurement into the battery, you may have a 1 ohm in series to the battery path from pin2. voltage across it , would be current thro the path to battery.
still voltage across PIN5 and PIN2 is 0.
One more help: Where can find I "Helped Me" button? Shall I give the points who helped me?
