Metabo ASC 55 – Universal Charger 12V 18V 36V Li-Ion / LiHD – CAS

Universal charger for all 12‑36V slide-on batteries, with patented “Air Cooled” technology for fast charging and extended battery life. Ideal for those who use Metabo or CAS-compatible tools: it allows charging batteries of various voltages with a single charger, simple, efficient, and suitable for construction sites or workshops.

The Metabo ASC 55 is a charger designed to offer maximum flexibility and practicality to those who use cordless tools. Thanks to its compatibility with 12 to 36V battery packs and its adherence to the CAS system, a single charger is sufficient to recharge batteries of various voltages—ideal for those with different tools who don't want multiple charging bases.

The patented “Air Cooled” technology ensures that the battery is cooled and maintained at an optimal temperature throughout the charging cycle: this reduces thermal stress on the cells, extending their useful life and allowing faster recharges.

The internal microprocessor system intelligently manages charging: it assesses battery conditions, regulates current and temperature, and ensures the best balance between time and cell care.

With its low weight and compact shape, the ASC 55 is easy to carry to construction sites, workshops, or laboratories. The charger is suitable for charging compatible Li-Ion and LiHD batteries and is perfect for users who want to reduce downtime and always keep batteries ready for use on drills, grinders, screwdrivers, hammers, and other cordless tools.

In essence, the ASC 55 represents an efficient, universal, and durable charger—a "must-have" accessory for those who frequently use cordless tools and want a reliable and versatile charging system.

FAQ – Frequently Asked Questions

Which batteries is the ASC 55 compatible with?

It is compatible with all 12V to 36V Li-Ion / LiHD slide-on batteries, including those from CAS system partners.

How long does it take to charge an 18V 4.0Ah battery?

Approximately 80 minutes. If the battery is 8.0Ah, the time can reach approximately 160 minutes.

Can I use the same charger for batteries of different voltages?

Yes. The ASC 55 is "universal": it handles battery packs from 12V up to 36V with the same charger.

Does the battery overheat during charging?

No — "Air Cooled" technology cools the battery during charging, keeping it at an optimal temperature.

Is it suitable for professional use on construction sites?

Yes. It is robust, compatible with powerful batteries, and designed for intensive use with professional tools.

Is there any warranty declared?

Yes — as with other CAS system products, batteries and chargers come with a warranty, regardless of the number of charging cycles.
