Professional Charging Made Simple
The STIHL CM 8 Charging Management System gives professionals the control and convenience they need to keep battery tools ready for work. Whether you’re managing a landscaping crew, running a maintenance fleet or working from a mobile setup, the CM 8 helps you charge more – without the hassle.
Efficient Power Management
Designed for demanding commercial use, the CM 8 connects up to eight STIHL chargers through a single power source. Its two-bank system automatically alternates between charger groups to prevent overloading, allowing you to power as many as 32 AP batteries in a single charge cycle. This makes it ideal for overnight recharging or day-long workshop operation.
Fast, Flexible, and Safe
Each charging bank supports up to 1,840 watts, giving you the flexibility to mix chargers such as the AL 101, AL 301, AL 301-4, and AL 501 without exceeding safe limits. The CM 8 automatically manages load distribution to protect your electrical setup while maintaining fast, consistent charging speeds.
Compact and Easy to Install
Installation is straightforward – plug it into a standard 230-volt socket with no qualified electrician required. Its slim, lightweight design allows wall-mounting for a tidy, efficient layout, especially when paired with the STIHL CR 6 wall rack. This makes it equally practical for workshops, vehicles, or site cabins.
