Record physical and electrochemical characteristics of batteries
According to NR-SRD-139:
- Visual Inspection: Inspect cells/ batteries for any deformations such as scrapes, bulges, or dents. Record all findings.
- Measurements of Physical Properties: The length, width, and height need to be measured and recorded. Length, width, and height are defined as the following:
- Length: The horizontal length of the battery with the serial number upright.
- Width: The vertical length of the battery with the serial number upright.
- Height: The smallest dimension.
- Measurements should be recorded with 0.1mm precision. Record the mass of each cell/ battery with 0.1g precision.
- Electrochemical Characteristics:
- Measurement of Open Circuit Voltage: Measure the Open Circuit Voltage (OCV) using a multimeter and record the value for each of the cells/ batteries. Measurements should be recorded with 0.1 V precision.
- Measurement of Closed Circuit Voltage: Ensure that the cell/ battery is at least charged to 4.0V before proceeding. After setting up the programmable load to a constant current of 1.875A, load the battery and wait for 30 seconds before recording the Closed Circuit Voltage.
