100% of PSP bnatteries sold are garbage.
If your OEM battery is puffy, carefully breal the pastic apart and cut the battery's PCB out of it. Then soilder a 3.7v LiPo battery in it's place. You can order new battery shells, or 3D print your own... But in my personal experience, it's best to just remove the UMD drive (since everyone plays from MemoryStick anyway) and put in the 4000mAh battery.
The first solution is too hard for me, and regarding the second one, I still have UMDs I want to play. What 4000mAh battery are you talking about? How long does it last? Would the PSP have two batteries and just use that one?
