The discharge test is started with the high current rate and when T1 is reached, the voltage at the battery terminals is recorded. Reduce the current to the second rate and proceed with the discharge test. A type 2 modified performance test is used when the duty cycle is more complex.
Step-1: Ensure instrumentation is operational & properly connected to the battery for continuous monitoring of discharge voltage and current. Step-2: Measure the float voltage of the each cell/unit to ensure appropriate flotation. Step-3: Disconnect the charging current from battery.
There are a number of different tests like: visual inspections, specific gravity, float voltage and current measurements, discharge test, individual cell condition, inter-cell resistance, and others, which are recommended in IEEE, NERC and other standards for diagnosing the condition of the battery banks.
This post demonstrates the procedure to test the capacity of a battery. The test will determine and compare the battery’s real capacity to its rated capacity. A load bank, voltmeters, and an amp meter will be utilized to discharge the battery at a specific current till a minimum voltage is achieved.
