A battery charger typically determines when a battery is fully charged by monitoring the voltage and current. As the battery approaches full charge, its voltage increases and the charging current decreases. Some chargers also use a technique called "negative delta V" detection, where they look for a small drop in voltage that occurs when a battery reaches full capacity, or they may monitor the temperature of the battery to prevent overcharging.
