About Alzner Battery
Alzner Automotive GmbH develops and manufactures battery storage systems at its site in Grafenau (Baden-Württemberg, greater Stuttgart area) under the RESBATT and ALLWATT brands. RESBATT is a portable, modular lithium-ion system with docking station and bidirectional inverter for mobile and stationary applications; ALLWATT is a stationary high-performance storage system for industrial applications such as peak load management, grid stabilization and the integration of renewable energies. Production is based on pouch cell technology with patented cell frame and cell connector systems that enable a wide variety of module sizes – from a compact single module to large-scale battery systems. In addition to highly automated processes and digital production planning, cell and battery testing in the company's own laboratory as well as customer-specific module manufacturing for prototype phases are available. The company builds on more than 20 years of experience in sheet metal processing, is IATF-certified and employs around 200 staff in development, production and quality assurance.
