New 3.6V 1800mah Rechargeable Battery for Sony PSP-110 PSP-1001 PSP 1000 FAT US

not to best quality, better off with official OEM
these are labeled as "brand new" but do not act like new batteries. not sure they are even real Sony brand. At first when charging it, it would say 65% and in several minutes it's up to 100%... and when it's in use it only lasts about an hour or so. When fully drained the PSP does not fully turn off and acts irrationally with the battery inside. Looks like the battery does not fully discharge when fully drained. Not reliable and certainly not good quality.
