Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh). A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) the battery can provide for some amount of time (generally in hours). Voltage * Amps * hours = Wh.
Since this is a particularly confusing part of measuring batteries, I'm going to discuss it more in detail. Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh).
If you know that the battery voltage is 18 V and current is 6 A, you can that the wattage will be 108 W with the following calculation: How to calculate power? If you are still not sure how to calculate power with the provided formulas, or simply want to save your time, you can use our Ohm's Law calculator.
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).
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.
As you might remember from our article on Ohm's law, the power P of an electrical device is equal to voltage V multiplied by current I: As energy E is power P multiplied by time T, all we have to do to find the energy stored in a battery is to multiply both sides of the equation by time:
So if the Nominal Capacity is given as 400Ah at a discharge current of 25A, this equates to a C-rate of 16 hours (400Ah divided by 25A). In other words all parameters are relevant to a …
