CMWTEC’s semiautomatic battery filling machines offer a flexible, high-precision solution for manufacturers who require the technology of a fully automated finishing line in a compact, manually assisted format. Developed as standalone units or laboratory equipment, our Semiautomatic range is ideal for smaller production runs, quality control environments and R&D facilities.
The Semiautomatic Equipment range includes machines for AGM vacuum filling, gel filling and mixing, volumetric initial filling, acid filling and levelling, high-rate discharge (HRD) testing and high-voltage (HV) testing. Each machine is built on the same technical foundation as our fully automated Premium Line – delivering the same precision, reliability and process accuracy in a semiautomatic format.
Semiautomatic machines from CMWTEC are designed for ease of operation. Intuitive controls, robust construction and quick changeover times make them the preferred choice for battery manufacturers who need flexible, dependable equipment without the complexity of a full automation setup.
Whether you are producing lead-acid, AGM or gel batteries, our semiautomatic range covers the essential stages of the battery finishing process. All machines are manufactured at our headquarters in Runkel, Germany, and can be configured to meet your specific battery types and production requirements.

With German engineering at its core, our modular concept turns individual machines into a scalable production system that grows with your requirements.
You can start with a compact setup and integrate additional modules whenever your capacity, processes or product portfolio change. This keeps your investment efficient today and your production flexible for tomorrow.
Our modular machines can be combined into flexible production lines and various machine set-ups – exactly as your process requires. In addition to proven setups, we also support individual requests and tailor-made solutions for your specific needs.
Whether you choose an established combination or develop your own – we’ll help you build the perfect system.
CMWTEC offers complete solutions for battery production—ranging from stand-alone machines and fully automated lines to advanced testing equipment and smart handling systems. Our modular approach enables flexible configurations and seamless integration into existing processes. With the DataManager software, we also provide digital tools for process control, traceability, and production data management. From assembly to end-of-line testing, CMWTEC delivers efficient technology for the entire battery production workflow.












The machine combines a semi-automated handling process with a fully automated filling process. The battery is evacuated inside and outside, and the acid is filled under vacuum in the patented Vacbox system. Air inclusions during filling are avoided.
Yes. The filling heads can be adjusted to the distance of the battery cover holes, and change-over times are short. The machine is designed for AGM and VRLA car, truck, telecom and industrial batteries from 20 to 70 kg. As an option, a weighing system can be installed before and after the Vacbox filler.
Each filling head has its own flow meter, which ensures an exact volume per cell. The acid volume is dosed by a volumetric measuring system, and the filling level is accurate to ±0.5 to 1% of the volume.
