Home > Product Lines > ECO Line Equipment
CMWTEC’s ECO line battery finishing equipment bridges the gap between high-performance technology and cost-efficiency. Designed for lead-acid battery manufacturers who demand reliable, precise machines without the full investment of a Premium Line setup, our ECO Line delivers consistent quality at an optimised price point.
The ECO Line covers the essential stages of the battery finishing process: volumetric acid filling, acid levelling, post-brushing, post-greasing, plug insertion, battery washing, air leak testing, high-voltage testing, high-rate discharge testing and battery labelling. Each machine is built on the same engineering principles as our Premium Line – ensuring durability, accuracy and seamless integration into your production line.
ECO Line machines are designed for flexibility. Whether you operate a smaller battery production facility or require a cost-efficient solution for specific process steps, our ECO Line equipment adapts to your exact requirements. Individual machines can also be combined with Premium Line equipment to create a hybrid battery finishing line tailored to your needs.
Manufactured at our facility in Runkel, Germany, every ECO Line machine meets strict quality standards. CMWTEC’s ECO Line is the ideal choice for battery manufacturers seeking proven German engineering at an efficient investment level.

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.















It fills sulphuric acid into automotive car and truck batteries from 20 to 70 kg, at up to 6 batteries per minute depending on fill volume. The machine is a single station.
The fill volume is pre-selected. While the filling heads sit in the filling holes, a flow meter controls the volume, and when the pre-selected volume is reached, the fill stroke rises and the next battery is fed in. The filling accuracy is ±1% of the volume.
Batteries arrive on the conveyor of the finishing line and are positioned exactly under the filling unit by a fixed stopper system. The machine connects to the acid supply system of the factory, and its construction is 100% acid resistant.
Both fill up to 6 batteries per minute with an accuracy of ±1% of the volume. On the ECO Line machine, battery heights are adjusted by a vertical spindle. The Premium Line machine has a servomotor-controlled height unit and a servo-driven up and down movement.
