Overview
- The two family-owned German firms announced the alliance on Thursday to make Stihl’s ALLPRO battery system the shared power source for Stihl motor tools and Kärcher professional cleaning devices.
- Stihl will begin selling new ALLPRO batteries built with tabless-cell technology on August 1, 2026, promising higher peak power, longer run times, faster charging and up to about 3,000 charge cycles.
- Kärcher will introduce the first compatible devices and batteries on January 1, 2027, and has set aside roughly €10 million to adapt its product lineup while continuing service for its legacy system.
- The ALLPRO packs remain backward-compatible with Stihl’s existing AP batteries so current Stihl customers can use their batteries in future Kärcher devices, while Kärcher users will need to migrate to the new system.
- The partnership targets professional operators who use multiple machines off-grid and positions ALLPRO to compete with established pro ecosystems such as Metabo’s CAS and Bosch’s AmpShare while inviting other makers to join.
