USB Rechargeable Batteries

Neat. But the charging circuit is a resistor and diode, which means the battery won't last if left continuously to charge. The capacity is also rather limited (1300mAh; typically AA NiMH achieve 2000~2500mAh.) I just use a twin-AA smart NiMH charger (USB powered), plus you're not stuck with buying a specific battery when one of the NiMH die.
