We meticulously evaluate the formation and conversion of PbSO4 to ascertain round-trip electric power reserve and supply performance of the plates through numerous charge and discharge cycles. In our battery testing station, we simulate extreme conditions (such as constant high or low temperatures, constant high-power discharges, and short circuit current tests) and conduct destructive testing on completed batteries to determine their electric limits and prevent potential micro-short-circuits. Beyond electrical tests, regular experiments on semi-products are conducted. We cut open the inter-cell connections to inspect the welding quality and verify the internal terminal installation status, ensuring premium sealing quality and preventing any leakage. Our firm belief is that comprehensive knowledge of our batteries is essential before delivering them to our valued customers.
