just to clarify a little bit more you need to start up a CFW psp with an ac adapter then stick in the card then the battery then run the program from the 1.5 kernal....
But im guessing you dont have a CFW psp in that case the esayest thing for you to do is hardmod your battery which takes all 5min then just play off your ac adapter till you get a new battery.
Note if you hardmod your battery make sure you install 3.71 on the stick via totalnewbie esay installer otherwise you will have no cfw on your psp because you cant install w/o a battery charged more then 78ish%
Edit* there is some program out there that can suposidly fix a hardmoded battery some people say it work some say it doesnt. I wouldnt rely on it to work 100% but there is a chance it could work for you.... you can find the info in the tutorial section i dont have time to look for you otherwise i would put a link
