I went down to S P road today, was looking for few 18650 batteries!! one guy offered me a ultrafire 4200mah for 50rs!! so here i'am wondering how do i test the battery mah rating, i did some googleing and found out i could use a constant current load and a stopwatch to figure it out!! is there a easier way because i need to build a whole circuit, and im not much into electronics!!and i got a samsung 2200mah for 245rs, which i think is geniune because the seller is a battery supplier!! can someone help me out here!!

JK

ultrafire  ,

make sure thats original, i have 3 of them 4000mah and 4200mah. but all are duplicate can be charged using 1Amp takes only near 1 hour from 3.4v to 4.2.
they looks same as original ultrafire, and got many other with UltraFlrc, UltaFire, UitraFire etc.

yup, those are just fake, and if you open up one of them you'll find a small lipo battery!! contacted chintal sir for the bettery and opened up a dell laptop battery which i got for free from a source, but the problem is i cant find the same identical batteries!!
