How To Calculate Battery Voltage

How To Calculate Battery Voltage. We first convert the capacitance mah, milliampere, into ampere; Load (how many amps the battery is discharging at that moment), cell being evaluated (which chemistry or model), temperature of the battery, and general health of the battery.
