FloatsWe offer a large variety of floats to help control electrolyte levels in the cell with the greatest accuracy. Choosing the correct float is crucial in achieving the best level in battery cells. The large choice of floats allows you to adjust electrolyte levels in all battery types and in all areas of application.
This Is How You Choose the Correct Float
The type of float depends on the type of plug, the cell vent diameter and the depth measurement (T), that is, the distance between the upper edge of the cell vent and the upper edge of the separator. bfs standard floats, which work for most lead-acid batteries, have a diameter of 22 mm. Floats with diameters of 19 or 14 mm are considered special floats that are used for smaller than normal battery interiors.
