Modern day electronic devices, such as cell phones and MP3 players, can usually be powered with either an adapter or USB source through a single input connector using a mini USB cable. For a simple charger, without separate power paths for the system and the battery, the system (including the device transceiver) is powered directly from the battery. If the battery is deeply discharged, it has to - Charging a three-cell nickel-based battery pack with a Li-Ion chargerPDF, 127 Kb, File published: Apr 26, 2012
