Since 1980 bfs has been exclusively producing single point watering systems for industrial batteries.

The basic element of the system is the bfs plug whose most important operational and flexibility characteristics are protected by key patents. The reliable, well tested mechanism inside the plug allows the battery to be filled with water at pressures ranging from 0.2 to 3.8 bars (3 - 53 psi). Only bfs offers such a unique performance and a variety of specialty plugs to meet specific needs of the battery industry.

30 years of research and development have shaped the technology of this system. The production and sales of over 7,000,000 plugs per year have made the company the global market leader in this field.

德国Batterie Fullungssysteme公司（BFS）自1980年成立至今，独家生产工业电池单点加水系统。

       该系统的基础要素是BFS加水旋塞，其操作功能及灵活性以获得专利保护。旋塞内可靠、经验证效果良好的结构使蓄电池在0.2-3.8巴（3-53磅/平方英尺）的压力下加水。只有BFS公司可提供这种独特性能、功能多样的旋塞，极大满足了蓄电池工业的特殊需要。

       BFS公司30多年的研发经验促成了这项先进的系统工艺。公司旋塞的年生产及销售量达700万个，无疑是该领域市场的领导者。
