How Many Amps To Charge A Car Battery. Note that rounding errors may occur, so always check the results Battery Capacity Calculator Battery Capacity in mAh= (Battery life in hours x Load Current in Amp) /0.7 Battery Capacity = (Hours x Amp) / Run Time % Wher
How to Calculate Battery Life? Battery Life calculator uses battery_life = capacity *60/ consumption to calculate the Battery Life, Battery Life estimates how long a battery will last, based on nominal battery capacity and the average current that a load is drawing from it. Battery capacity is typically measured in Amp-hours (Ah) or milliamp-hours (mAh), although Watt-hours (Wh) is. Wh = ( VCharged 2 - VDepleted 2) / (7200 / C) You can see here that if you are using a capacitor to replace a battery, you really need to be running it into a boost converter with a suitable input voltage range so you can discharge your capacitor down to very low volts, taking our example above, if instead of a 3.3v cut off voltage, we had a 0.
To calculate the watt hours (WH) of a battery pack, simply multiply the voltage by the amp hours (Ah) of the pack. A 36-volt 10-Ah battery pack has 360 watt hours (36 X 10 = 360). If you are nitty with your energy usage, each mile you travel will cost you about 20 watt hours. Therefore a 360 watt hour pack will get you about 18 miles Watt itself is defined as Ampere X Voltage. So if a 5 Volt battery has 20 Watt Hour rating, and, it draws 2 Amp current, then the Watt delivered by Battery = 10 Watts ( 5 Volts x 2 Ampere). The battery will last 2 hours. The calculator will calculate the battery life if the Watt Hour and the battery voltage is known. Here is the formul Electric Skateboard calculator, for speed, range, power and other settings This calculator is designed to assist you with power usage amounts, when converting from one power form to another using a DC to AC inverter.

Using Ohm's law and a nominal voltage of 3.7V, current capacity is easily converted to power capacity. A 2 Wh battery can deliver two Watts continuously for one hour, one Watt for two hours, etc, half a Watt for four hours, etc
Insert milliamp hour (mAh) and voltage (V) and click on Calculate to obtain Watt hours (Wh). Formula is (mAh)* (V)/1000 = (Wh). For example, if you have a 300mAh battery rated at 5V, the power is 300mAh * 5V / 1000 = 1.5Wh. Secondly, how many mAh is 44.4 Wh Related: resistor calculator Ohm's Law. Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage. This is true for many materials, over a wide range of voltages and currents, and the resistance and conductance of electronic components made from these materials remains constant its capacity in ampere-hours (Ah). Multiply these two numbers to get the watt-hour rating (Ah × V = Wh). Note: If the capacity of your battery is expressed in milliampere hours (mAh)—like in the image above— you will need to divide by 1,000 to calculate the ampere-hours (Ah) before multiplying. If All Else Fails, Contact the Manufacture To measure discharge, take a fully charged primary or secondary cell. Put a constant current load on it, say, 100 mA. Start the timer, and Measure the voltage continuously, when it gets to the terminal voltage, check the time. The capacity in mAh.

Always check the results; rounding errors may occur mAh vs Wh . In the modern world hand held or portable devices are very popular and common. These devices are powered by batteries and draw little current and designed to consume minimal energy. When parameters of these batteries are considered, the values are small and hence smaller units are required to express them. The mAh and Wh are two. Actually, watts is the fundamental unit of power and watt-hours is the energy stored. The key is to use the watts you know to calculate the amps at the battery voltage. For example, say you want to run a 250 watt 110VAC light bulb from an inverter for 5 hours. Watt-hours = watts * hours = 250 watts * 5 hours = 1250 watt hour Also, if you're studying a faradaic i.e. redox based system, you can't use the term Capacitance (in F) in your energy and power calculations, you should use Capacity (in C or mAh)
