New Users Of E-cigs Wonder About Battery Life

New users of e-cigs often wonder about the battery life of their e-cigs. The battery’s life varies depending on certain factors. Still, some things remain general for all types of e-cigs. We are going to use the Ego electronic cigarette that has 650 mAh as an example.

Miliamperes

On the box, it says 3,7 volts, so you could use the C4 Vipercig clearomizor, that has a 2,5 ohms resistance. First of all, you should know exactly what 650 mAh (miliamperes) mean, so you’ll be aware of what you’re dealing with. It means that in the case you have a charge applied to a battery and you touch the thread, this will deliver until 650 miliamperes, for an hour. So, what is the quantity of charge that the Ego electronic cigarette will deliver and for how long?

Ohm’s Law

Using Ohm’s law, or power consumption equals the tension divided to resistance, we can calculate that a battery of 3,7 volts, with a charge of 2,5 ohms, will attract about 1,48 amps (1,48 miliamperes) of power. Consequently, as the battery is evaluated as delivering 650 mAh of power in an hour, we can simply divide, 640 mAh to 1480 mAh to determine how long the Ego battery can deliver the quantity of eliquid. In this case, we are talking about 0,43 of an hour, which means about 26 minutes. But really, no one is going to hold the button down for 26 minutes, as after 10 seconds you risk to burn the atomizor, not to mention the fact that e-cigs have protection against this kind of thing.

Variables

How often do you smoke? How many times do you puff from an electronic cigarette? For how long do you keep the button down that activates the battery? We’ll take a random example and then leave you to calculate after your own variables.

Let’s say that someone has the tendency to keep the button down for about 5 seconds each time he / she inhales and this person puffs approximately 40 puffs an hour. So, for each hour we use an average of 3 minutes and 20 seconds from the 26 minutes (5x40=200, 200/60=3,3). Taking this into account, an Ego’s battery life lasts about 7 hours (26/3,3). If you calculate, you will see that actually, the time frame is of about 7 hours and 46 minutes, but the Ego’s battery will stop before the power supply will be completely exhausted, to protect the battery from being completely drained.

So, this is the rhythm in which you can puff from an electronic cigarette and have the battery last for 7 hours. Keep in mind though that this time frame will change as time goes by and the battery gets old. After a few months, those 650 mAh will become 475 mAh and so on.

Now, depending on the type of electronic cigarette you have, you can make your own calculations based on the equations we gave above and remember that as a new user, you might have the tendency to puff more often than others who have been using the e-cig for a while, so your battery life may be shorter.
