Convert 100ah to wh

By Tithdara Koy Last updated: June 15, Where Ah is the energy value in amp-hours, V is the voltage of the energy source, and Wh is the equivalent energy value in watt-hours.

Or would you rather convert amp hours to watt hours? You know it's a 12 volt battery, and you want to calculate its amp hours. Note: Most people use a battery's nominal voltage when calculating amp hours or watt hours, but it's worth reminding you that a battery's actual voltage is slightly different and varies based on its remaining capacity. Some brands have started reporting their batteries' capacities in watt hours -- particularly for solar generators aka portable power stations. This is helpful for making an apples to apples comparison of the energy these batteries can deliver.

We understand that all this terminology can be a bit confusing at times but once you know how it works it is quite simple. Below we will try to explain what it all means. For calculations we recommend using our Trolling motor tool. On tab 3 of this tool you can calculate Watts, Amps, Voltage and Watt-hours. The number of volts is the amount of energy given to an electronic circuit. By a circuit we mean, for example, an electronic device. A battery always has a fixed voltage e. For example, a device that works on 12 volts obviously needs a battery that also supplies 12V. If the number of amps goes up, then current flowing through the device per second also goes up. An electrical device usually works on a fixed voltage, but the amount of amps it draws can vary depending on, for example, the position of your trolling engine a trolling engine at full throttle draws more amps than in half throttle for instance. The trolling engine runs on 12V and currently draws 15A. The engine still runs on 12V but now pulls 25A. The voltage has remained the same but the number of amps has gone up. This is the amount of energy consumed by a device and therefore an indication of how powerful it is. This goes up when the number of amps also goes up.

So the number of watt-hours always remains the same, whether you connect them in series or parallel.

Or would you rather convert watt hours to amp hours? To calculate your battery's watt hours , you'd multiply its amp hours by its 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.

Here is a nifty amp-hour calculator that converts watt-hours to amp-hours. You can also check the battery amps hours chart for 12V and 24V batteries here. You can also do the reverse conversion. To help you out, we have created a similar Ah to Wh converter here. It might be interesting to read our articles about battery-operated heaters here and battery-powered air conditioners here. Battery capacity also plays a key role in the mileage of electric vehicles.

Convert 100ah to wh

Understanding battery specs can be pretty confusing, right? While both units Ah and Wh are used to express battery capacity , they are not the same. Amp-hour — short for Ampere hour — is a unit of electric charge. Meanwhile, a Watt-hour is a unit of electrical energy. It describes the energy capacity of a battery.

Share This Article. In practice you will notice that these batteries will be around the same dimensions and weight. He lives in Tennessee. Either by dividing the number of Amps of the battery by the power draw in A of the trolling motor or by dividing the number of Wh of the battery Wh by the number of W of the trolling engine. To convert its amp hours to kilowatt hours, you'd do the following:. Batteries can be connected together to achieve a higher voltage or higher capacity. And when we do, we see how wrong we were:. This is a protection to prevent damage. Let's say you own a 12V Ah lithium battery. Maximum charge current: This gives the maximum current in A at which the battery can be charged. We need to take voltage into account for both batteries, and we do that by calculating their watt hours. Wh is calculated by multiplying the number of Amps with the battery voltage.

A Ah battery is a standard off-the-shelf product you can buy at any physical or online store. They are usually rated at either 12V or 24V, which indicates the battery voltage.

By a circuit we mean, for example, an electronic device. In the picture above, the minus terminals of both batteries are connected and the plus terminals are connected. To calculate your battery's watt hours , you'd multiply its amp hours by its voltage:. We connect the minus wire of the electrical appliance to one of the minus terminals and the plus wire to the plus terminal of the other battery see the picture below. Turns out his generator's battery has a capacity of around Ah. That is why we always refer to our capacity as Capacity C1-C We explain how this works in our article discharge and battery capacity. So, to convert kilowatt hours to amp hours, you multiply kilowatt hours by and then divide by volts. So, to convert milliamp hours to watt hours, you multiply millamp hours by volts and then divide by Volts V Error: This field is required. C1, C5, C this indicates battery capacity when discharged in a certain number of hours.
