Abstract
A method for charging batteries, in particular lithium batteries, includes the steps of connecting a battery electrically to a battery-charging apparatus, dispensing electric power to the battery by means of the battery-charging apparatus, and regulating the electric current and voltage dispensed by the battery-charging apparatus to the battery. The regulating step includes the steps of detecting the voltage at the terminals of the battery and regulating the voltage dispensed by the battery-charging apparatus, during a phase of constant-voltage battery charging, depending on the voltage detected at the terminals of the battery, to compensate for parasitic voltage drops existing between the battery (1) and the battery-charging apparatus.
