Ultra-M Technology

Advancement through innovation: the Metabo Ultra-M technology

The secret behind Metabo's Ultra-M Technology is the high level of communication that takes place between the tool, the battery pack and the charger. This communication helps assure the battery does not over or under charge, or over draw itself.  It also monitors and maintains an optimum energy usages resulting in a longer service life for all components.


  • Optimum motor technology for any application

  • Intelligent battery management - for maximum performance and service life

  • Electronic Single Cell Protection (ESCP) - for extremely long battery pack service life

  • Patented »AIR COOLED« charging technology – for faster charging and longer service life

  • Secure investment in a compatible, sustainable battery pack system

»AIR COOLED« – resume work much faster

Quick Charger ASC Ultra

The ASC Ultra significantly reduces charge time for your battery pack - an empty 18V/5.2 Ah battery pack can be ready for use again in just 45 minutes. The patented "AIR COOLED" charging technology cools the battery pack in the charger with air - for shorter charge times and longer service life.

Always the right charger
The model is compatible with all slide-fit battery packs from 14.4 V - 36 V. Charge times are dependent on the capacity of the battery pack.

Charging times:
3.0 AH: 27 min
4.0 AH: 35 min
5.2 AH: 45 min
