The battery expert I was refering to is http://www.batteryuniversity.com which is also a reference in that guideline from Wiki.

The guideline from Wiki stated:
Unlike Ni-Cd batteries, lithium-ion batteries should be charged early and often.
Lithium-ion batteries should never be "deep-cycled" like Ni-Cd batteries.

So it's advisable to charge the PSP often. Letting the battery discharge completely or to very low battery capacity before recharging reduces the Li-Ion battery's lifetime.

is there any indication when the PSP is full charged..
i'm using PSP slim CFW 3.71 M33-2, i'm thinking wheter to upgrade to 3.71 M33-3 or not, can the pro give suggestion..

Need help from all the sifus in here. I just bought a psp slim and it's running 3.71 m33-3 custom firmware. I wanted to run some homebrews (emulator and pdf reader). I put the files in the GAME150 folder as per the instructions but it does not work. The error message is "The game could not be started. (80020148).

Anyone can help me solve this problem? I was so looking forward to run a few homebrews 

Anyone in here can help me on this matter please? 

When the battery is fully charged, the orange power LED will turn off.
I suggest that you upgrade to 3.71 M33-3 because it fixed bugs found in the earlier version.

i know that i can upgrade it myself, but i'm afraid of bricking my psp..
so can i just go to any shop that sell psp and ask them to upgrade it, if can where is the best place to go

basically there is 2 type.. multiplayer worldwide or local.. as i know.. monster hunter is local.. either ad-hoc with friend.. or via xkai(online multiplayer)

for the CFW.. region is not a problem anymore..

I think the chances of bricking is quite slim since upgrading from 3.71 M33-2 to M33-3 involves running the update program which will overwrite only a few files in flash0.

If you're still afraid, go to those reputable shops such as GS, SCE, PSZ.

Any1 used a Fake Sony MSPD on psp before?izit good?

since its no need access flash0 using usb so the chance is so small will cause the brick.. except when u updating the psp suddenly turn off.. or mspd got problem of reading..
