Cordless Alliance System
One battery that fits all.
What is the Cordless Alliance System?
The Cordless Alliance System (CAS) is a collaborative initiative among over 45 leading power tool manufacturers that allows users to operate a wide range of tools using a single battery platform, specifically, the 18V battery system developed by Metabo
CAS batteries, chargers, and tools are fully interchangeable across all participating brands. This means you can use one battery to power over 400 tools from manufacturers like Metabo, Mafell, Lamello, Starmix, and MANY more!
The system centers around the 18V class, which is the most commonly used voltage for professional-grade tools. CAS also supports LiHD and LiHDX battery technologies, offering high power output (up to 3200W), longer runtimes, and faster charging.
How Can The Cordless Alliance System Be Used?
With more than 30 years of battery pack expertise, Metabo is the pioneer in battery pack technology. CAS is a cross-manufacturer battery pack system of leading power tool brands and offers you a large selection of powerful machines.
Now you can combine machines, battery packs, and chargers of different manufacturers with each other without any problems. By reducing the need for multiple batteries and chargers, CAS helps users save money, reduce clutter, and minimise environmental impact. CAS tools are used across various industries, including construction, metalworking, plumbing, woodworking, and facility management. Examples include cordless vacuum cleaners, crimping machines, pipe saws, and impact wrenches.
Mobile working without cable offers numerous advantages, including:
- Independence from the wall socket for more flexibility and productivity.
- No tripping on cables, i.e. increased safety thanks to lower risk of accidents.
The CAS partner is an alliance of generalists and specialists with a clear focus on power tools for professional applications. The alliance unites innovative power, high performance of the products, and the common goal of making professionals independent from the power socket.
