It is suitable for turbo-charging 14.4 to 18 V Li-Ion batteries of Bosch cordless power tools. The Multivolt Quick Charger offers a quick charging time. An air-cooling system circulates fresh air through the battery to keep its temperature between 0 and 45 degrees C. This significantly reduces the charging time and enhances the chance of a longer lifetime for the battery. The asymptotic charge algorithm of the charger offers quick charging times.
