What Does Amp Hour Mean?

Knowing all the numbers and ratings on a battery is the key to picking up a perfect battery that support your RV, boat, home solar power system.You don’t want to buy a battery that is short on capacity or you are new to the world of batteries might be confusing about the terms of battery. In this blog post, we will cover amp hours to watts, and other important terms you may hear when referring to a battery’s power.

Meaning of Amp Hour in Batteries

Amp-hours, abbreviated as Ah, is one of the most useful tools used to tell the battery capacity. It is a rating tells us how much amperage a battery can provide for exactly one hour. The higher amp hours, the longer your battery can sustain its electrical flow.

Thus in general, if you are planning to buy a battery for your RV or providing multiple devices at a time, you’ll probably want a battery with a much higher Ah rating, or vice verse.

C Rating

Most deep cycle batteries will tell you the Ah rating at multiple C ratings. The C rating tells you how many amp hours the battery can provide for a very specific period of time. It means that a fully charged battery rated at 1Ah should provide 1A for one hour.

What is a Watt-Hour?

Watt hours is a unit of energy that measures how much work can be done by a certain amount of power over a period of time. One watt-hour is equal to one watt of power flowing for one hour.

Calculating watt hours is pretty simple. You’ll want to factor in both the current (amperage) and the voltage of the battery. Here’s the equation:

Watt Hours = Amp Hours × Voltage.

Amp Hours to Watt Hours

Although amp-hours and watt-hours are different, they share a close relationship. Both values are related to the battery performance. In short, Amp hour(Ah) is capacity while Watt-hour(Wh) is energy.

The formula that change amp hours to watt hours

Watt hour = amp hour X voltage

You can also change watt hours to amp hours using the formula below;

Amp hour = watt-hour/Voltage
