Non-Sealed Technology

With their classic construction, non-sealed batteries require periodic manual servicing and maintenance. They are an economical and dependable option for vehicles with lower electrical requirements. A defining feature of this product group is the accessible caps on the battery body, which allow users to inspect electrolyte levels at set intervals and add distilled water when evaporation occurs, particularly during hot seasons. This interactive design is highly practical for users who value preventive checks and periodic technical care of their vehicles. Ultimately, serviceable batteries deliver the best efficiency for vehicles without complex systems such as Start-Stop and with standard electrical equipment.
