The Metabo ASC 55 Air Cooled Slide Charger charges all Li-Power Compact, Li-Power Plus, Li-Power Extreme and LiHD slide-on battery packs (12-36V). Monitors charging via a microcontroller and delivers acurate battery diagnosis. The charger switches to compensation charge: to conserve the capacity, the battery pack is charged for 1 second every 45 seconds with 2.5 ampere.

With a '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.
