update:
i managed to get 3 batteries from the shop that sold me the unit. he says he doesnt bring in brand names cause they hardly sell so he brings these in ... they are UNLABELED but he's told they are 2500mah batteries.
they all are the same color. no writing on the batteries at all. just pink in color (wrap)
i plopped into the rx200 and the work ok.
Dude no. No! He doesnt sell name-brand batteries? Is his shop a Costco or Walmart or some crap? I regret my last post already. You have no clue who made those batteries. You have no clue of the specs unless this seller tested them before selling them. Holy crap no.
