Insten Rechargeable Replacement Battery 1200mAh 3.6V Compatible with Sony PSP 3000 / PSP Slim 2000, Include Model PSP-2001, PSP-3000, PSP-3001, PSP-3002, PSP-3004

I had my device in the attic for years and the battery expanded and doesn’t work no more. Once I replaced with this one then it worked just like when I had the original battery.

I was good suff

VERY GOOD

Best replacement battery for both my PSP-1000 (Phat) model.The one battery I've had for about a year now and just recently purchased another for my second PSP.Below is an attached review I did for the GENERIC 36000mah PSP replacement battery.Disclaimer:Personal experience may vary.Performance:I bought this 'Generic 3600mah' and an INSTEN 1200mAh PSP battery for a comparison test.Hands down the INSTEN brand performs a lot better.The INSTEN holds a charge longer and, lasts longer on continuous playing of the PSP.Weight/feel comparison:GENERIC is a lot lighter and feels cheaply manufactured.INSTEN has good weight and sturdy construction.My Suggestion:Go with the INSTEN 1200mah (3.6v) brand.Optional Alternative:If you want ultimate portability and long lasting game play then buy yourself a slim high capacity battery bank and a PSP barrel charger with USB on one side. Attach the battery bank to the back of the PSP and plug in the PSP. The PSP will remain functional until the battery bank runs out (Hours of Play) ;)There are youtube videos on Battery modifications but it removes the UMD drive.---I am in no way affiliated with the INSTEN brand or any of its affiliates.This is simply my honest opinion on which brands I have tried.

not good.

New battery does not hold a charge.

Shortly after purchasing the battery, less than a few months later the battery will no longer charge and my psp wont power up with my battery in the slot.

The battery does not seat properly into the psp 3001. If the system gets wiggled wrong at all while this is in it will force a hard reset.
