Testing with basic hipot or insulation resistance test instrumentation does not provide any indication to whether the space between the electrodes is safe enough to undergo the charge/discharge cycles of the battery. Partial Discharge (PD) detection in addition to insulation resistance testing, like what’s found in the Chroma 11210, could detect those defects in the dry cell stage prior to electrolyte filling. Detecting burrs or particles early in the production phase allow for these cells to be filtered out before shipment. This can greatly increase product quality, reduce failures, and mitigate any danger that may come from an internal electrical short.
