What is a battery capacity calculator?

Battery capacity calculator — other battery parameters FAQs If you want to convert between amp-hours and watt-hours or find the C-rate of a battery, give this battery capacity calculator a try. It is a handy tool that helps you understand how much energy is stored in the battery that your smartphone or a drone runs on.

How to calculate battery output?

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).

How to calculate battery capacity in Mah?

Battery Capacity in mAh = (Battery life in hours x Load Current in Amp) / 0.7 Battery Capacity = (Hours x Amp) / Run Time % Where; Note: In an ideal case, the battery capacity formula would be; Battery Capacity = Battery Life in Hours x Battery Amp Related Posts: Enter value, And click on calculate.

How do you calculate the run time of a battery?

To calculate the run time of a battery, the following formula is used: Battery Capacity in mAh: The total charge the battery can hold, measured in milliampere-hours (mAh). Battery Voltage in V: The nominal voltage of the battery. Device Power Consumption in watts: The power consume by the device being power by the battery, measure in watts.

How do you measure a battery capacity?

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. What is the C rating of a battery? The C rating determines the rate at which the battery discharges.

How to calculate battery life?

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.
