A feature of batteries that indicates whether they can withstand vibrations particularly well.
Swollen glass fiber separators in AGM-based batteries or the gel-like immobilized electrolyte in GEL batteries ensure that the grids are securely placed and the active material does not loosen from the grid. Thus, it is available for the electrochemical reaction in the battery and the performance of the battery does not drop prematurely. In extremely shake-proof batteries, the plate packs are also crompessed and glued into the case.
There are different standards for vibration resistance: V1 - for standard requirements in passenger car batteries, V2 - for standard requirements in commercial vehicles, V3 - for increased requirements, V4 - for extreme heavy-duty vehicles in factory and commercial use.
