hey there i have a psp slim the first one released and i its battery 3.6V 1200mAh exploded:/ i just wondered if an old battery pach 3.6V 1800mAh of the first fat psp released is compatible with the slim one if not can you suggest me what to do??
No, the battery for the 1000 series cannot be used in a 2000 or 3000. On the very bottom of it (with the screen facing up and the shoulder buttons furthest away from you), you should see a barcode with the model number. If it says 1000 (or 1001 or something similar), you have a fat model. If it says 2000 or 3000, you have a Slim model. The 1000's battery doesn't fit in the 2000 and 3000's compartment. Sony does make replacement battery packs, however, as well as an Extended Life Battery Kit. If you use your PSP a lot, I really recommend getting the Extended Kit. It takes the normal battery life from 3-5 hours to 5-11. The only problem is it's bigger, and a bigger battery means a bigger cover. They only provide black and silver battery covers. It's not a huge problem, but it is there.
