The relationship between voltage and state of charge in a battery is not linear. As a battery discharges, the voltage gradually decreases until it reaches a certain point, after which the voltage drops rapidly. Similarly, as a battery charges, the voltage increases slowly until it reaches a certain point, after which the voltage rises more rapidly.
