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.
The Battery Run Time Calculator is a pretty productive tool. It is used for estimating how long a battery will last based on its capacity and the power consumption of connected devices. By inputting the battery's voltage, ampere-hour (Ah) rating, and the device's power draw in watts, this calculator can determine the approximate runtime.
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 C rating determines the rate at which the battery discharges. The higher the discharge rate (i.e., higher C ratings), the lower the total capacity of the battery. For example, if you have a 60Ah battery rated at 1C, this means that it is capable of delivering 60 A of current continuously in 1 hour. How fast the battery charges and discharges.
Battery runtime is often referred to as “theoretical” because it is calculated based on some ideal conditions and assumptions. These assumptions include: Battery capacity: The runtime calculation assumes that the battery has a specific capacity, usually expressed in ampere-hours (Ah), which represents the amount of energy the battery can store.
