Capacity Testing Capacity tests should not be run unless the battery’s operation is questionable. Do not discharge the batteries beyond the specified final voltage. When discharging at higher rates, extra connectors may need to be added to pre- vent excessive voltage drop. When performing capacity test- ing and recording data use IEEE 1188 instructions.
