    Battery voltage vs state of charge for lead acid battery.

    I am using PIC MCU for measuring battery voltage & cut charging at 14.5V around. Now I want to calculate SOC acc to voltage.

    is there any mathematical formula to write in C to calculate SOC at charging & while at open circuit.

    Edit: wrong subject written :), don't know how to edit it.

    You need to monitor current as well to have any chance of success.
