Overview of Rechargeable Batteries and Fast Stand-Alone Chargers

Abstract: This application note provides an overview of nickel-cadmium (NiCd), nickel-metal-hydride (NiMH), and lithium-ion (Li-Ion, Li+) rechargeable batteries, discussing their characteristics and explaining how to safely fast charge NiMH and Li-Ion rechargeable batteries in a stand-alone configuration, without the use of a supervising microcontroller.
