Enter the values of current, I b (A) and internal resistance, R b (Ω) to determine the value of battery voltage, V b (V). Battery Voltage is a fundamental parameter in electrical engineering and electronics, indicating the potential difference across a battery’s terminals.
Suppose a battery has an internal resistance of 0.3 ohms, and the battery voltage is 0.9V. Calculate the current flowing through the battery. Given: V b (V) = 0.9V, R b (Ω) = 0.3 Ω. Battery voltage, V b (V) = I b (A) * R b (Ω)
Here the formula will be Battery (day) = Capacity (Ah) / 24 x I (Ah) Battery (month) = Capacity (Ah) / 30 x I (Ah) Battery (year) = Capacity (Ah) / 365 x I (Ah) Sometimes, you may do not know the output current; hence you can calculate the battery output by below formula Load current (Amps- Hour) = Total Load (W) / battery Voltage (volts).
The total battery pack voltage is determined by the number of cells in series. For example, the total (string) voltage of 6 cells connected in series will be the sum of their individual voltage. In order to increase the current capability the battery capacity, more strings have to be connected in parallel.
To measure a battery's capacity, use the following methods: Measure the time T it takes to discharge the battery to a certain voltage. Calculate the capacity in amp-hours: Q = I×T. Or: Calculate the capacity in watt-hours: Q = P×T.
