WebIf the readings range between 12 and 12.3 volts, your battery is operating at 75% and doesn’t need to be replaced too soon. Finally, if your battery is operating in critical condition and around 11.8 volts or less, this means that it is operating at around ¼ or 25% of its full capacity. It should be replaced as soon as possible. Conclusion WebVolts calculations. The voltage V in volts (V) is equal to the current I in amps (A) times the resistance R in ohms (Ω): The voltage V in volts (V) is equal to the power P in watts (W) divided by the current I in amps (A): The voltage V in volts (V) is equal to the square root of the power P in watts (W) times the resistance R in ohms (Ω): samplemoog download
