A Nice utility by developer Frostegater for our PSP Genesis competition. It gives you a bunch of useful information on your PSP battery, its temperature, etc… This allows you to identify a damaged or non working battery.

Note that, as the screenshot below shows, the information is unfortunately incomplete for the PSP Go.

Here is the full list of features from the author:

• Charge Level
• Time to discharge
• Voltage
• Battery temperature
• Identification of the external power supply
• Weak charge
• The availability of battery
• Charging
• EEPROM Access
• Serial Battery
• Mode Battery
