How to Measure OCV of Battery: A Step-by-Step Guide
The OCV of a fully charged battery is higher than that of a partially charged or discharged battery. Measuring the OCV can help you estimate the SOC of a battery and determine when it needs to be charged. 2. Detection of Defective Cells. Measuring the OCV of battery cells during production can help detect defective cells.

How Batteries Are Measured
Voltage The voltage of a battery cell is determined by the chemistry used inside. For example, all Alkaline cells are 1.5V, all lead-acid''s are 2V, and lithiums are 3V. Batteries can be made of multiple cells, so for example, you''ll rarely see a 2V lead-acid battery. Usually they are connected together inside to make a 6V, 12V or 24V battery.
