I noticed that my PSP 3004 battery does not last as long as it used to. I do not know if there is anything that I can do to fix this problem, but I assume that as is the case with all batteries this one has reached the end of it's lifespan. Apparently there are some 3rd party products out there as well as some rare 1st party ones. Now, there are some pictures of the alternatives that I have. I could not find any english reviews (or any reviews at all) for any of these. If you are familiar with any of these products please inform me, so that I can purchase the right one. By the way, if I am not mistaken 1000 series and 2000/3000 series use different batteries, so these ones must be 2000/3000 batteries. If there is any mistake please let me know: Which one of these would you recommend?
