For those who ask the question .. This battery cheap but handy (because avoids having pandoriser the battery of your PSP and then having to dépandoriser / normalize after use) is compatible PSP Fat [1000] PSP Slim [2000] but not PSP Bright [3000] (The latter incompatibility is not due to the battery, but the new PSP 3000 motherboard that allow not to use a pandora battery).
