To properly charge a battery, the charger has to be capable of taking a battery through three charge stages. The first stage is a bulk charge stage in which the charger supplies a majority of the power to the battery until it reaches termination voltage. During the second stage the termination voltage has to be high enough to fully charge the battery and remain at that constant termination voltage for an hour to destratify the electrolyte and return it to a set level of specific gravity. Finally, in the third stage, the charger goes into a standby mode that keeps a battery fully charged without over charge.
Advanced solid state circuitry make the charger light and compact.
