The battery packs impress with highly efficient and gentle charging, optimum energy utilisation and an extremely long service life. Metabo Ultra-M technology stands for optimum coordination and perfect communication between the machine motor, battery packs and charger. A multifunctional monitoring system continuously records both the battery temperature and the amperage. The electronic single cell monitoring (ESCP) also ensures a long battery life. Thanks to the patented "Air Cooled" charging technology, the battery packs in the charger are cooled with air - for shorter charging times and a longer service life. The capacity indicator allows the charge level to be monitored at all times. The battery packs can be stored for a long time. Scope of delivery: 2x Metabo Li-Power battery pack 5.2 Ah (625592000).
