What is the Principle of Battery? (Details Explain)
How fast a battery charger can force current through a given battery depends on the technology of the charger and the type of battery being charged. Lead acid batteries, for example, are typically charged with relatively low currents compared to other chemistries such as nickel-cadmium (NiCd) or nickel-metal hydride (NiMH).
