# Convert 100ah to wh

By Tithdara Koy Last updated: June 15,

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. But, it can be helpful to convert watt hours to amp hours when designing a solar electrical system.

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. 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. Voltage is like the water pressure, while amperage is like the flow rate. Although Battery B can output its electrons at a higher 'flow rate', they flow at a lower 'pressure'. On the other hand, Battery A can output its electrons at a lower flow rate, but they flow at three times the pressure. The extra pressure more than makes up for the smaller flow rate, meaning that Battery A ends up delivering more energy.

I have a 12 volt battery of 70 ah. Energy density is much higher for lithium batteries than for lead-acid batteries.

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 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. This concept holds for other ampere values as long as the multiplication process results in Ah. For example, you can draw two amps for 50 hours, four amps for 25 hours. We can do this through the power formula. We are not showing off. Converting Ah to Wh will come in handy later in our discussion. When deciding whether you should get a lead-acid or lithium-ion Ah battery, you must first understand what applications you have in mind. There are endless ways to utilize energy storage. However, typical 12V Ah batteries are usually for running small to medium appliances in RVs, boats, camps, among others.

### Convert 100ah to wh

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.

### Cattywampus definition

The electrical device should be connected to these two available battery terminals. We have now created a 12VAh battery. Volts V Error: This field is required. This is done by connecting the battery terminals of the batteries with cables. By this we mean that this battery can be compared to a lead battery with the indicated capacity when used in combination with an electric motor. Youtube Tiktok Instagram. The voltage has remained the same but the number of amps has gone up. With this we mean the average of this progression or the nominal voltage. Below we will try to explain what it all means. As an Amazon Associate, we earn from qualifying purchases. The attentive reader notes that the runtime of a battery with a device can be calculated in two ways.

Understanding battery specs can be pretty confusing, right?

When we say that we connect batteries in series, we connect the plus terminal of one battery to the minus terminal of another battery. 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. Read more about this in our article about effective battery capacity. With this we mean the average of this progression or the nominal voltage. Volts V Error: This field is required. Suppose a battery has a maximum continuous discharge of 30A, then you cannot connect a device that draws more than 30A. All Rights Reserved. On the other hand, Battery A can output its electrons at a lower flow rate, but they flow at three times the pressure. Voltage: this is the voltage that the battery delivers on average. For calculations we recommend using our Trolling motor tool. Alex Beale Hi, I'm Alex.

I think, that you are not right. I am assured. I can prove it. Write to me in PM.

Idea excellent, I support.

What words... super, remarkable idea
