# E-Cigarette Battery mAh: Guide To More Puffs

There is no question that the **battery** serves as the main **power source** for any **electronic cigarette**, which means that understanding the **E-Cigarette battery mAh** can be extremely helpful in determining the actual number of **puffs** **vapers** can get out of a **full charge**. Normally, **battery** **power** is measured by two distinct parts, the **voltage** (**V**) and the **milliampere-hour** (**mAh**) **rating**. The **volt** describes how a current of one **ampere** will be able to flow through a conducting agent that has a **resistance** of one **ohm**.

**Ampere** or **amp** on the other hand references the **steady current** that is produced by a single **volt** that is acting through a one **ohm** **resistance**. This means that **ampere-hour** is the **steady current** defined by an **ampere** over a period of one hour, and **milliampere-hour** (**mAh**) is 1/1000 of the **ampere-hour** **rating**. Considering that **battery** **life** is considered as one of the more essential determining factors in the **usage** of **electronic cigarettes**, it is vital for **vapers** to understand **E-Cigarette battery mAh** ratings through the following steps.

**Finding the Amps**

Usually, more **battery** **life** translates to more freedom to use the **electronic cigarette** virtually anywhere the **vaper** wants to. This means not having to deal with running out of **battery** **charge** or having to **change batteries** **midstream**. There is no doubt that every **vaper** would want to have a **satisfying** **vaping experience** anytime they want and anywhere they want. This only becomes possible if the **battery** holds up to the actual **usage** of the **vaper**.

The first step in determining just how many **puffs** you can get away with in a single **full charge**; you must understand how to determine the **amps** to get to the **E-Cigarette battery mAh**. Every **vaper** will see that when shopping for **electronic cigarettes**, **batteries** are commonly described in the specifications using the **mAh** **value**. Many **vapers** will assume that the higher the **mAh**, the better the **battery** is without actually taking the time to understand the implications.

The key is to understand how the **mAh** **rating** of **electronic cigarette** **batteries** would translate to the actual **usage** of **vapers**. The **vaper** must be aware just how much **amps** the **cartomizer** or **atomizer** along with the **battery** draws. For example, **vapers** who are using 2.5 **ohm** **atomizers** with 3.7 **volt** **batteries** will normally draw 1.48 **amps**. This **value** would hold true for majority of **electronic cigarette** **brands** in the market today.

Using a different **voltage** **battery** or perhaps an **attachment** that makes use of a different **resistance** **level** will have significant impact on the **amps** **value** of the **electronic cigarette**. For easier calculation, **vapers** are urged to use the **Ohm’s Law Calculator** to get the appropriate **amps** for their specific combination. They must remember that the **value** they get will be in **amps** which means it has to be multiplied by a thousand to get the **milliamps** equivalent.

It is vital to take note that the **resistance** of majority of **atomizers** and **cartomizers** currently being sold by the **electronic cigarette** **industry** would vary by a **value** of 0.2 **ohms** in any direction. It is equally important to note that the **voltage** of the **electronic cigarette** **battery** slowly degrades as it is being used. The number of **puffs** that **vapers** arrive at will not be exact, but based on the **mAh** **rating**, the **value** can be quite realistically close to the actual **usage**.

**The Battery Life Calculator**

After successfully getting the **mAh** **rating** for the **electronic cigarette** **battery** being used, the next step is to use the **Battery** **Life** **Calculator**. Enter the **value** in the **Battery** **Life** **Calculator** along with the 1480 **value** for the field requiring the **consumption of** **device**. The **value** provided by the **Ohm**’s Law **Calculator** may also be used as a significant reference for the **mAh** **value** of the **electronic cigarette** **battery**.

When the **values** have been placed, simply click on **calculate** to get the result for the expected **battery** **life**. The **value** will normally be represented in hours. It is important for **vapers** to be aware that the accuracy of the result will depend mostly on the **mAh** **rating** **value** of the **electronic cigarette** **battery** being tested. If the **E-Cigarette battery mAh** **rating** **value** is wrong, then definitely, the succeeding **results** will automatically be faulty.

The resulting **value** of the **life** of the **electronic cigarette** **battery** in hours should be a significantly small number like 0.132 for example. This means that if large **values** are received, there is something exceptionally wrong with the previous **computations** you have made. The hours **value** must be multiplied by 3600, which represents the number of seconds in one hour.

This will give **vapers** an idea of just how many seconds they can take with every **puff** that they make on the **battery**. An **electronic cigarette** **battery** that has a **rated capacity** of 280 **mAh** should come up with the result of 475 seconds. Anything that deviates from that is an error in previous **computations**.

**The Final Figure**

Once all these **figures** have been sorted out and presumed to be correct, they can now be put together to come up with the desired **results**. **Vapers** should be aware just how many seconds their **puffs** last on the average. This is important because the number of seconds that you received based on the **mAh** **rating** of the **electronic cigarette** **battery** must be divided by the **average length**, in seconds, of the **puff** of the **vaper**.

Taking the previous example of using an **electronic cigarette** **battery** that has a 280 **mAh** **rating**, this resulted in 475 seconds of **estimated** **battery** **life** for every **full charge**. If the **vaper** has an average of 3-second long **puff**, the expected number of **puffs** that can be generated from that **fully charged battery** would be approximately 158 **puffs**.

It is important to point out that this **value** based on the **E-Cigarette battery mAh** is only **estimated** because of two important **reasons**. First is that the **voltage** of the **battery** will inevitably drop during **usage**, and second, the **duration** **and** **intensity** of the **puff** varies considerably among **vapers**.

Understanding these steps will help all **vapers** to effectively gauge the effective number of **puffs** they can receive based on the **E-Cigarette battery mAh** **rating**.
