Metabo 627045000 ASC 55 with processor-controlled charging management for gentle charging and maximum number of charging cycles The Metabo 627045000 ASC 55 is equipped with an \"AIR COOLED\" function. The patented principle is based on air-cooling the battery pack during the charging process. The battery packs are gently cooled down to the required charging temperature, and then during the charging process are constantly maintained at optimum temperature. With this principle, a higher tool life of the battery packs and up to 30% shorter total charging time can be achieved. Features: For charging all Li-Power and LiHD slide-on battery packs (12 V - 36 V) with adapted battery pack charging current Patented \"AIR COOLED\" charging technology: battery pack cooling during charging for significantly reduced charging times Processor-controlled charging management for gentle charging and maximum number of charging cycles 3-year warranty on all Metabo battery packs and chargers irrespective of the number of charging cycles Many brands, one battery pack system: charger for charging all battery packs of the CAS brands: www.cordless-alliance-system.com Specification: Battery voltage: 12 - 36 V Mains voltage: 240V Mains frequency: 50 - 60 Hz Max. charging current: 3 / 4 A Output rating: 55 W Charging time for 18 V/4.0 Ah: 80 min Charging time for 18 V/8.0 Ah: 160 min Weight: 0.582kg
