Combined strength and extremely powerful

ROTHENBERGER has a wide range of battery-powered tools for many different areas of application: from special equipment for SHK professionals to standard tools. Whether it's a press machine, pipe inspection camera or drill screwdriver: all devices are CAS-compatible.

The powerful CAS batteries and chargers can be used for all CAS battery tools and can be combined with each other. The sophisticated battery technology comes from Metabo.

18-volt-class LiHD rechargeable batteries.

ROTHENBERGER offers 18 V CAS batteries in 2 Ah, 4 Ah and 8 Ah. The LiHD batteries in 4 Ah and 8 Ah are characterized by their particularly compact shape, as their cells are densely packed - hence the name Lithium High Density (LiHD) batteries. Each cell generates heat. Therefore, LIHD batteries have a particularly efficient temperature management.
