It is inadmissible to provide "certified battery compliant" when it is clearly a vulgar forgery! I realize it before using it because it is very slightly offset from my other two branded batteries owner: so be abnormally force for her to get into the housing provided for this purpose. But sommum comes recharge time: I put more than 8 hours with my Samsung external charger while it does put at the time that 2:30 with the same charger when my other batteries were new. Then, use it took 1 day and 6 hours in extensive use, so I do not have to complain at this level. But I am sorry to have clearly chosen this product because the description stated "certified" and I finally have the inconvenience that I intended to avoid at all costs !!!
(Addition) A week later, I happily been repaid by the seller for the non-compliant battery. Still a bright spot in all this ...
