Urgently needed a replacement battery for PSP Classic in order to get going again. Have become here immediately find and the only practical application has been successful, to say the battery is operating as desired and the PSP was fully functional again as the first day. Also recommended as a replacement battery that eventually wears off the power of each battery with time. But you should make sure that this battery fits only in the PSP classic because it is slightly thicker than the for the PSP Slim. When Slim it works even only gets you no longer on the battery cover.
