Mah to watt hour converter
There are just too many questions you will wonder when designing your device with a battery inside it. The boss just want a cheap and small battery with it, but with no further information on how long does the end customer wants, how small can it be.
If the capacity is given in amp-hours and current in amps, time will be in hours charging or discharging. Or if delivering 10A, it would last for only 1 hour, or if delivering 5A, it would last only for 2 hours. For a mAh 2. Things would be quite complicated as the battery would be in different shape Curved shape, Round,Rectangular etc and different discharging current 5C, 30C, or even up to C or even temperature requirement like low temperature battery. The material and Production technology will have an effect on the lipo cell capacity.
The actual capacity will be very complex, but luckily we have a simple and fast calculate formula. PS: quick notes: if space allows, cylindrical battery cells will always be your first consideration on the table. They are on the shelf and therefore has short lead time and small MOQ. Impotant note: above are max capacity as there is BMS and wiring cables included for a battery pack. How long will my battery run, this is a big question for many end users and even for some electronics engineer.
We here come with a simple battery time calculator that will tell you how long your battery will run. Some customers asks for 12v battery run time calculator ,.
You cannot convert watts to amps, HOWEVER, if you have at least two of the following three: amps, volts or watts then the missing one can be calculated. Feel Confused?
So how to calculate how long a battery will last? It is that simple. How to Calculate Battery Capacity? We here have 2 ways for you to get the battery capaicty. Energy Density of Different Battery Types. Online Size Battery Capacity Calculator. Thickness mm. Remarks: 1 the calculator does not apply to capacity less than mAh or 2mm less in thickness cells 2 If the capacity is not within the stated capacity range, try the other calculator 3 the capacity if for your reference, given the size, thickness, width, material, voltage, the capacity will still vary greatly from each other.
Battery Run Time Calculator. The Following Equations can be used to convert between amps, volts, and watts.

Convert mAh to Wh and Wh to mAh - Conversion Calculator
An essential part of any renewable energy system is the ability to store energy produced for future use. This is were your battery bank comes into play. Sizing a battery system to match your renewable energy system is dependent on three main factors, the size of your system, how much you intend to store for future use and how many hours needs to be covered. Once we have this information we can design a battery bank that is tailor fit to your needs.
Conversion - Watts, Amps, Voltage
Converting amp hours to watt hours makes it easier to compare how much energy different batteries can deliver. The total energy a battery can provide depends on both its amp hours and voltage, so only comparing amp hours can lead you to some erroneous conclusions. But these batteries have different voltages, so only comparing their amp hours is like comparing apples to oranges. We need to take voltage into account for both batteries, and we do that by calculating their watt hours. Once we do, we can make an apples to apples comparison of the amount of energy they can provide. And when we do, we see how wrong we were:. Electricity can be thought of like water flowing through a pipe.
How to convert mAh to Wh
The calculator works by filling in any of two of the three fields volts amps watts to calculate the value of the third field. This tool can convert any value as long as you enter the two other values. Click Calculate. Here is one example of how this calculator is commonly used by security system installers as an amp calculator.

In order to convert mAh to Wh and Wh to mAh one must introduce another value, since basically, mAh describes the capacity of the, for example, a battery, while Wh describes energy provided or stored by a battery, a capacitor, and similar. In order to convert mAh milli Ampere-hours to Wh Watt-hours , the following formula must be used:. If the battery capacity C is given in mAh milli Ampere-hours, one thousendth of an Ampere-hour , we must use these formulas:.
Watt Hour is defined as the power of the battery that could provide the specified energy for one hour and after that battery drains off. In case if the battery provides more energy then the discharging time decreases. Online tools for wire gauge calculator and wire size chart Please select awg from drop-down list or can also enter gauge value and select wire from drop-down list and enter Resistivity and click the calculate button to obtain result. Use this online converter for Wh watt-hours to mAh milliamp-hours calculation.
