I was playing donkey kong country 2 on snes9tyl. The battery drained rather quickly. Said 0%. Then when I went back to the psp menu, it went back up to 80%. Obviously the battery is acting up. I know sony doesn't make official ones anymore. I can't find any decent ratings on third party batteries. So I was thinking of buying these: http://tinyurl.com/j2zwal5 http://tinyurl.com/zjb5bhq Would this be a good solution?
