Alfred Kärcher SE & Co. KG and Andreas STIHL AG & Co. KG have announced the launch of a joint battery alliance.

The companies say the aim of this strategic partnership is "to offer professional users a common, high-performance and future-proof battery standard".
The alliance is based around the ALLPRO battery system developed by STIHL, which will be used in the professional equipment of both brands in future.
Michael Traub, chairman of the executive board of STIHL AG explained, “Professional users need more than just high-performance tools. They need systems that cover a wide range of tasks, reduce complexity and ensure their investment pays off in the long term. This is exactly where ALLPRO comes in. The partnership with Kärcher expands the scope of our battery system to include further professional applications, thereby creating added value in our customers’ day-to-day work.”
Hartmut Jenner, CEO & chairman of the board of management of Alfred Kärcher SE & Co. KG, added, “Through the synergy between our equipment, we are creating far more than just a technical solution: we are consistently driving forward the electrification of professional applications, thereby securing a decisive competitive advantage for our customers."
Professional users will in future be able to use the same batteries and chargers for both their Kärcher cleaning equipment and their STIHL power tools. STIHL customers will have full compatibility with the existing AP system - and existing AP batteries can also be used with the new Kärcher battery-powered devices. For Kärcher customers, ALLPRO is an entirely new platform. However, Kärcher say they continue to guarantee full service, spare parts and battery availability for existing devices from the previous Battery Universe.
The result, say the two companies, is a working environment for professionals in which they can cover the entire spectrum of daily landscaping, forestry and cleaning tasks with just one battery system. The new batteries will be available from STIHL specialist retailers from 1 August 2026. Kärcher will launch the new batteries and the new tools on 1 January 2027.
In addition to these two companies, numerous other partners - including those specialising in forestry winches, equipment carriers and mobile refuelling systems - will be incorporating the ALLPRO battery system into their equipment. This means that users in the forestry and landscaping sectors, the construction industry, facility management and aid organisations have access to a range of more than 120 devices, all powered by the same battery packs. A charging and energy management system rounds off the offering.
