This test aims to identify individual failed or near-failed cell batteries at an early stage for replacement—thus ensuring the effectiveness of the entire battery bank—or to assess the expected service life of the entire battery bank.

Partial discharge refers to an electrical discharge that does not cause a complete short circuit between electrodes. The magnitude of such discharges is usually very small, yet they can indeed lead to a gradual deterioration of insulation performance, eventually resulting in failures of electrical equipment.
