He just does not fit. I own a PSP "Fat" version 1004 lt. Product description ie 100% pasgenau and compatible. And? The original battery can insert, turn the PSP and it does not fall out everything. This one does. In the original you can (albeit fiddly) donned the cover. Here impossible. The three contacts on the battery are also wrong on yet, so I doubt that as an ordinary contact is even made. And as the grand finale wobble that thing also, because he has a slight bulge on the underside.
He is also lighter than the original, which to me indicates that it is simply to endorse China-Fake. Disregarding for example even with batteries for the Wii Remote. Thickness mAh numbers plan print, which then turn out to be fake.
Access have too much money now for all of us here like. One probably. is indeed "only" the production tolerance as high and you are caught NEN good copy.
