BatteryDAQ - Model Sentry-6002-NiCad - Battery Monitoring System Datasheet

High quality vented Ni-Cad batteries in standby stationary applications can last for 20+ years, but they need proper maintenance in order to prolong the battery service life and optimize DC system performance. Without monitoring, inspections and maintenance can be scheduled on a calendar basis. However, manual verification of a large number of cells is time consuming and unreliable, especially for terminal connection resistance and inter-cell connection resistance measurements. Effective monitoring provides remote indications of abnormal operation and cell condition, including battery bus voltage, charging current, string continuity, temperature, electrolyte level, cell voltage, and corrosion caused by potassium carbonate (gray-white deposits) buildup. Effective monitoring also automatically records the discharge performance and facilitates scheduled capacity testing.
