Does Battery Changing Really Works?

i would like 2 know wats the difference between each batter life time from actualy ppl not by sony or who ever selling it...thanks guys :D

I got the generic extended battery they sell on ebay from China.  They advertise double life.  But its only about 50% more.  My psp usually says 11 hrs instead of the 7 hrs my OEM battery stated when fully charged.  Still its good enough for me and for $12 shipped not a bad deal. crck
