Battery Watering

the hydrodynamic battery watering system

Technology

Implementation of the Hydrodynamic Principle

First engineered more than 25 years ago, the original AquaPro filling caps revolutionized the industry by harnessing hydrodynamic force to seal the system and dramatically increase fill speed.

Through continuous development and refinement, we are now proud to introduce our fourth-generation design.

The new Generation IV filling plug sets a new benchmark for precision and sustainability. With improved tolerance control, upgraded plastics, and a complete redesign of key components, this latest iteration delivers performance equal to—or exceeding—that of any system on the market today.
