The charger fully recharges 64v max Makita batteries at 4.0 Ah in 120 minutes. The batteries are simply placed on the charger and snap into place by means of a hook that must be pressed to remove the battery. Once the battery is inserted, the color of the charging indicator light changes from green to red and the charging process begins. The charging indicator lamp is constantly lit during the charging process. At a state of charge of 0-80%, a red charge indicator lamp lights up, while at 80-100% a red and a green lamp light up. The above 80% display is an approximation. When charging is finished, the red and green charging indicator lights switch to a green light. The charging time varies depending on the temperature (10°C - 40°C) at which the battery is charged and the condition of the battery.
