As a lead acid battery discharges, the voltage decreases linearly. For example, a 12V battery may provide 12.6V when fully charged. After discharging halfway, the voltage will drop to around 12.3V. The rate of discharge impacts the voltage. Faster discharge rates result in lower voltages for a given state of charge.
The voltage of a lead-acid battery also varies with temperature. At room temperature, the voltage of a fully charged lead-acid battery is around 12.6 volts. As the temperature of the battery decreases, the voltage of the battery also decreases. Similarly, as the temperature of the battery increases, the voltage of the battery also increases.
