Abstract: Two connected electronic devices may use a controller and two power converters to share battery charge. The two electronic devices may share charge after one electronic device's battery is completely discharged. In the alternative, the two electronic devices may compare the relative age of the two batteries and if the age difference exceeds a predetermined threshold, the younger battery may share charge until it is insufficiently charged to power both electronic devices.
