— Intelligent battery storage solutions. Made in Germany.
Our Approach
Alzner Battery develops and manufactures innovative high-performance energy storage systems for stationary, mobile, and industrial applications based on high-end storage technologies. These are divided into two distinct brands and product lines:
– RESBATT – a portable system for flexible applications
– ALLWATT – a stationary high-performance storage system for efficient energy utilization
We focus on the highest safety and quality standards and develop sustainable solutions that deliver real value for our customers – made in Germany.
— Energy that thinks ahead, acts flexibly, and masters every challenge.
Our Products
— The Portable, Modular Power Pack.
The portable battery system from RESBATT provides reliable energy anytime and anywhere – whether mobile or stationary. It delivers sufficient power for a wide range of applications, is safe, scalable, and connectable, and operates reliably even under extreme conditions. A flexible energy solution, precisely when and where it is needed.
— Utilizing Power and Energy to the Full.
The ALLWATT high-performance battery system is among the most powerful solutions for stationary energy storage applications. Especially for industrial use, the modular system offers a customized and efficient approach to energy management. An intelligent battery management system ensures maximum safety and efficiency.
Advantages at a Glance
Versatile Applications
Mobile and modular energy storage for every situation – whether on construction sites, in the field, or during outdoor adventures. Thanks to the docking station with an integrated bidirectional inverter, off-grid power is instantly available – even under extreme conditions.
Stationary energy storage for industrial and demanding applications. ALLWATT delivers high performance and handles extreme power transients – reliably, safely, and efficiently. Ideal for peak load management, grid stabilization, and the integration of renewable energies. Designed for maximum availability and long service life – when reliability matters most.
Performance
RESBATT provides powerful and flexible energy both for mobile use and in combination with residential PV systems. With high charging and discharging power, short charging times, and a robust design, RESBATT reliably supplies a wide range of devices and households autonomously and safely – wherever energy is needed.
ALLWATT storage systems enable extremely fast charging and discharging cycles (up to >10 C) and allow a depth of discharge (DoD) of up to 100%, ensuring that the full usable capacity can be reliably utilized – without compromising the system’s lifespan or safety.
Sustainability & Modularity
RESBATT impresses with its sustainable product design: The pluggable, portable battery systems are designed for durability and can be individually replaced or recycled in the event of a defect. This not only conserves resources but also contributes to COâ‚‚ reduction. The simple plug & play logic enables quick transport and commissioning without the need for specialized personnel. This innovative concept has been recognized with the iF Design Award 2025, among others.
ALLWATT relies on long-lasting cell technology and the highest quality standards. Our systems feature a modular design, allowing individual components to be replaced as needed. This not only simplifies maintenance and repair but also makes the storage systems particularly sustainable. When combined with PV or industrial systems, they actively contribute to COâ‚‚ reduction and adapt precisely to specific requirements thanks to flexible battery variants (Power, Hybrid, and Energy).
Risk Management
RESBATT provides safe mobile energy – featuring integrated fire protection, active thermal management, a robust housing design, and continuous cell monitoring. The system reliably protects against electrical, thermal, and mechanical risks, even in changing operating environments.
ALLWATT meets the highest safety requirements for mission-critical applications: multi-level fire protection, intelligent monitoring of all operating data, and reliable safeguards against electrical and thermomechanical risks ensure maximum operational safety and prevent failures in life-sustaining facilities.
Our Location
Our production is flexible, efficient, and designed for the highest quality. Modern technology, a high degree of automation, and strict testing standards ensure the reliability of our energy storage systems – scalable, adaptable, and future-ready.
With over 20 years of experience in sheet metal processing – IATF-certified and industry-proven – we bring deep manufacturing expertise to every system. Around 200 employees in development, production, and quality assurance make sure every detail is perfect.
The result: precisely engineered, durable battery systems – born from industrial experience and further developed for the energy supply of tomorrow.
— Moving forward with energy. Connected by energy.
Production
Alzner Battery develops and manufactures powerful, safe, and sustainable battery systems – entirely at its own site in Baden-Württemberg. Our production in Germany guarantees the highest quality standards, short delivery times, and full control over all processes – from development to final inspection.
Our systems are innovative, scalable, and flexibly deployable – whether stationary or mobile, for any application and location.
— Mobile and stationary power supply made in Germany.
Energy in Cell Networks
Many interconnected battery cells working together generate the overall performance of the energy storage system. This principle also applies to our company.
We therefore maintain close partnerships with selected companies as development and supply partners, as well as with research and testing institutes and various other organizations. The result is a concentrated, unified performance from a single source – for our customers.
— Harnessing networking, cooperation, and synergy.
