(most often wired in series to provide multiples of the basic cell voltageįor the battery technology - 1.2, 1.5, 2.0, or 3.0 V are most common). Sections below represent just a brief introduction.Ī battery is, strictly speaking, made up of a number of individual cells There is more on batteries than you ever dreamed of ever needing. The charging circuitsĪre often very simple and don't really do the best job but it is adequateįor more detailed information on all aspects of battery technology, see However, most of the devices you are likely to encounter still use prettyīasic battery technologies - most commonly throwaway Alkaline and Lithiumįollowed by rechargeable Nickel Cadmium or Lead-Acid. Voltages are required by the equipment at over 90% efficiency Low cost DC-DC converter designs are capable of generating whatever A variety of ICs are nowĪvailable to implement rapid charging techniques while preserving battery The inventory of popular battery technologies. Lithium and Nickel Metal Hydride are among the more recent additions to
