Battery Element Testers

All STS Battery Element Testers provide a unique method for the detection of assembly level insulation defects in lead-acid batteries, including missing and damaged separators. Detection of such faults prior to filling and charging the battery minimizes costly reclamation. Traditional AC dielectric tests can detect such faults, but may produce damaging heat in moist cell applications. To overcome this limitation, STS has developed testers that employ a high-voltage, short duration pulse to maximize stress to the dielectric material while minimizing average energy. The goal is to provide sufficient stress to cause current flow in the presence of a failure. This technique allows reliable fault detection while eliminating damage due to overheating that may occur with an AC test.
