With a powerful 12A charging current, the AL 501 significantly reduces charging times compared to standard chargers, helping maximise productivity and minimise downtime between tasks. It is compatible with both STIHL AK System batteries and STIHL ALLPRO/AP System batteries, making it an ideal charging solution for users operating multiple cordless tools across both platforms.

To maintain battery health and charging efficiency, the AL 501 features an integrated active cooling system. The built-in fan helps manage battery temperature during charging, allowing batteries to charge more effectively whilst protecting the cells from excessive heat.

The charger uses an intelligent two-stage charging process. Initially, the battery is charged at a constant current until a predetermined voltage is reached. The charger then switches to constant voltage charging, automatically reducing the charging current as the battery approaches full capacity. This process helps optimise charging efficiency and support long-term battery performance.

For added protection, the AL 501 automatically switches off when charging is complete, preventing overcharging and helping extend battery lifespan.

Practical features include an LED status indicator for monitoring charging progress, a built-in Velcro cable management strap for tidy storage and a wall-mountable design that helps save valuable workshop or garage space.

Whether you’re maintaining a single battery or managing multiple cordless tools, the STIHL AL 501 provides fast, reliable and professional charging performance.
