Recentally my Pandora Fat Battery has failed to charge and turn on. Likely the small gash in the side of the pack has corroded. I have cracked opened my Slim Battery with care but I do not want to hardmod it because I do not want to have to resolder the leg. I was wondering if there was any way to jerry rig the + and - to the + and - of the broken battery to power it on. I would just time machine it but the PSP i have now does not have it =/ thanks if you guys got some answers. small edit, the old broken battery is modded as a pandora battery, but has no charge.
