Hardware Battery Charging Questions

[Skeet1983]

I recently purchased a new PSP battery since my previous one was not holding a charge. When the battery came, I put it in system and it said charge was at 100%. I used it for several hours and I have noticed that the battery % was not going down. I played it today and system would shut off on its own. Tried turning it on again several times and it eventually would not turn on at all. Was the battery actually dead? I am charging now, and the battery % is 100, but it still says charging when I check Battery Information under System Settings. Anyone know what is going on here? Please help and thoughts appreciated

Battery Brand is KMD...

the battery is a knock-off right? not a original one from sonny or a good third party?

if it's a cheap ass battery, it doesnt have the chip or thing that tells the console the charge of it... making the console thinking is always 100%...
there are 3 pins on the battery, the positive, the negative and the middle one which if i am not mistaken it tells the info about the charge and serial of the battery...

How would I order one from Sony? PSP Model is 3001

I called Sony and they didn't have any batteries available for the 3001 Model. They said to check Amazon. I ordered the one at this linkhttp://www.amazon.com/gp/product/B003T0D4O2/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1)

I did not charge battery after I got it. Battery % said 100 for quite a while, then system started shutting off on own... Did the battery die? Anyone else experience this? Thoughts appreciated
