Based on these inputs, the battery calculator will compute the required battery capacity or life, helping you to select the appropriate battery for your needs, ensuring optimal device performance and avoiding premature battery depletion. Battery Capacity: Represents the storage capacity of the battery, measured in Ampere-hours (Ah).
The basic formula for calculating the capacity of a battery is to multiply the voltage by the current and then by the time. The formula is as follows: Where: Capacity is the battery's capacity in ampere-hours (Ah). Voltage is the battery's voltage in volts (V). Current is the battery's current in amperes (A).
Hence the battery life formula can be written as, Battery (h) = Capacity (Ah) / (P (W) / V (v)) = V (v) x Capacity (Ah) / P (W) The battery life is equal to the battery volts times of the battery capacity divided by the total loads. Hence, while increasing the load, the battery life will be reduced. Example: Let us consider the 12 v 100 Ah battery.
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).
To calculate amp hours, you need to know the voltage of the battery and the amount of energy stored in the battery. Multiply the energy in watt-hours by voltage in volts, and you will obtain amp hours. Alternatively, if you have the capacity in mAh and you want to make a battery Ah calculation, simply use the equation: Ah = (capacity in mAh)/1000.
The energy stored in a battery is calculated by multiplying the voltage of the battery by the capacity of the battery in ampere-hours. For example, a battery with a capacity of 1000 mAh and a voltage of 3.7 volts would have an energy storage capacity of 3.7 watt-hours (Wh).
