So, I have two portables--a PSP 3000 and a GBA SP--that both have proprietary batteries.
Now, personally, I always hated proprietary batteries because it basically means that if the battery goes bad, then you have to keep the system plugged in all the time because you can't simply buy new ones from the store (like you could if it used regular AAs or something).
Sadly, I think my GBA SP is fixing to prove my point. Twice now I've had power outages and thought to play it in the dark. Each time--both times I thought it had fully charged--it lasted for twenty minutes then turned itself off, not coming back on until I plugged it in. I even went back to using my normal GBA while wearing a headlamp.
I'm worried that my PSP (which is my favorite portable) will eventually go the same way.
My question is this: What can I do about it? Is it possible to mod these systems to make them use standard battery types? Or else to self-repair the actual batteries? I've already looked into replacement batteries (especially for the PSP) and that's clearly not an option--all I can find are bootleg batteries that have questionable performance.
Thanks in advance.
