Turn any standard PSP or PSP Slim battery into a TOOL Mode battery in seconds.
Battery Service Tool has the power to turn any standard PSP or PSP Slim battery into a TOOL Mode battery and back again, quickly and safely. Just slot your charged battery into the Battery Service Tool device – it's powered directly from the PSP/PSP Slim battery itself, so you don't even need an external power supply. Your battery is then converted into a TOOL Mode battery, which boots your PSP or PSP Slim in Service Mode. Put the battery back into Battery Service Tool and it's returned to its original state as a standard battery.
When you switch on your PSP or PSP slim with a TOOL battery inserted, the console boots in Service Mode, a special functionality previously only available to programmers and developers. When in Service Mode, you can boot software that's stored on your Memory Stick. It's easy.
