Rechargeable batteries have a finite lifespan, and the PSP battery is no exception. A PSP's battery has a preset limit of 500 charges, after which it rolls over and dies, and cannot be charged again. This charge limit is set by the manufacturer, and cannot be overridden when charging your battery in your console. However, Datel's Battery Charger contains an intelligent system that checks the state of your battery. If it's still in working order, it recharges even if it's reached its 500-charge limit. In most cases, the Datel Battery Charger lets you charge up to 600 times, extending its lifespan by 20%. • Actual appearance may vary. Features
