The present invention relates to a vibration-resistant accumulator with a housing (20), which comprises one or more cell boxes (16) each with a plate block (15) with positive and negative plate groups (14a, 14b), with the individual plates (1a, 1b) in a plate block (15) separated from one another by
The present invention relates to a vibration-resistant accumulator with a housing (20), which comprises one or more cell boxes (16) each with a plate block (15) with positive and negative plate groups (14a, 14b), with the individual plates (1a, 1b) in a plate block (15) separated from one another by separators (6), the plates (1a, 1b) of each plate group (14a, 14b) having lugs (2a, 2b) and being connected together electrically by cell connectors (3a, 3b). In order to provide a vibration-resistant accumulator that is improved relative to the state of the art, withstands severe loading, can be manufactured comparatively easily and inexpensively, and permits safe filling of the electrolyte, according to the invention it is proposed to provide a hardenable sealing compound (8), which fixes the plate block (15) in a cell box (16) in a substantially vibration-resistant manner, with the sealing compound (8) arranged above the plates (1a, 1b) of the plate block (15) and at least partially filling the space between the top of the plate block (15) and the cell connectors (3a, 3b) and with a sealant guide bridge (7) provided on the top of the plate block (15), and delimiting a region that is free from sealing compound (8) on the top of the plate block (15).
