Mine is a simple conjecture. Maybe everything is okay. First start by thoroughly cleaning the pins under the battery cover and try recharging a battery. It may be that everything is okay already. However, all the PSP batteries circulating online are shoddy and unreliable.
I've given you various tips and opinions but I don't want any liability or complaints in case of other disappointing purchases.
I wish you a happy new year.
So, I ordered the Ostent external battery from Amazon, it also came charged like the Ostent battery and it took quite some time to discharge, but like I said, the PSP doesn't blink when low in battery (so, it turns off all of a sudden when it's fully discharged) and the battery icon doesn't appear in the XMB when using it, it's uncomfortable to hold the PSP with it attached, it's tilted since I doesn't fit the back of the PSP properly (maybe it's my fault for not attaching it well), and if I'm not careful, it can mess up the UMD drive when taking it so I'll leave it hanging, thus it won't be tilted and won't mess up the UMD drive when taking it. Even if it's not supposed to use it this way, at least it's safer and it feels more comfortable holding the PSP this way, too. The external battery's LED is red when being charged and turns blue after fully charged.
I don't know if it can also charge the internal battery and I didn't try it and I took it while playing as well. I also don't know if the PSP should even be charged with it inserted (regardless if the internal PSP battery is inserted or not) and I charged the external battery overnight, which I don't know if it's right (I don't know how long it took to fully charge it). A week after charging it, the PSP still turns on (I've been checking every day to see if it still does) so I guess it's not faulty like the 4 internal batteries I used which wouldn't even charge, just for a very small period of time of after being fully charged, the PSP wouldn't turn on the next day. Assuming the external battery is fine, does it mean the PSP has a hardware problem that affects all internal batteries or they are messed up? I find it odd having 4 faulty batteries (3 of them are/were new). If it really has a hardware problem that affects internal batteries, why doesn't it affect the external? Also, I've been using the original battery cover.
