Abstract
Leak testing system (100) and method for leak testing a finished battery cell, comprising a vacuum chamber (4), a vacuum pump (6), a detecting and measuring system (1) to detect gases and/or vapors escaping from the cell, the gases and/or vapors deriving from parts and/or substances inside in the cell, and a capillary element (2) which connects the detecting and measuring system to the vacuum chamber and through which the gases and/or vapors leaking from the cell flow. The system further comprises heating devices adapted to heat at least one of the components of system, thereby making the system substantially memory-free.
