Electronic Cigarette Battery Life and E-Cigarette Enjoyment
E-Cig Battery Basics
Battery power for electronic cigarettes is measured in volts and milliampere-hour (mAH). Volts are the amount of current delivered from one ampere after passing through one ohm of resistance. Milliampere-hour is 1/1000 of the ampere/hour of a volt of current. Though these may be confusing, they are vital parts of understanding the battery power for e-cigs. Since the batter quality is a vital part of vaping enjoyment, it is important to understand what a good battery is. The battery life, or battery mAh rating, determines how many puffs a vaper can expect from a particular battery.

The length of the battery life determines how long the vaper can use the electronic cigarette without having to recharge. The longer the battery life, the longer the e-cig user can go without having to stop and recharge the battery. The longer the battery life, the more seamless the experience is, proceeding without interruption.
A vaper might think that the mAh value of a battery is the only determinant of how many puffs are available on one charge. This is not true, however. The resistance of the cartomizer or atomizer impacts the number of puffs a battery will produce. This means determine the amps that will be used for each puff. The voltage of the battery must be divided by the ohms of resistance of the atomizer to determine how much each draw uses. For example, a 3.7 volt battery with a 2.5 ohm atomizer draws 1.48 amps with each puff.
Different attachments or different atomizers change the amp value. This involves calculations that the user might not want to do. There is an Ohm’s Law Calculator that gives an accurate value of the number of amps for a specific setup without having to do all the calculations yourself. Just input values and get the calculations given back to you. The resulting figures are in amps, so you will have to divide by 1000 to get milliamps.
Calculate Battery Life
Using the Battery Life Calculator, input appropriate values from the Ohm’s Law Calculator and calculates the battery life in hours, such as thousandths. It should be a small numbers, as the total will be multiplied by the number of seconds in an hour, which is 3600. This gives an idea of how many seconds can be used for total puffs. For example, a battery with the mAh rating of 280 will yield 475 seconds for puffs.
Calculating Number of Puffs
The average length of a vaper’s puff needs to be determined to be able to figure the number of puffs that can be expected for a fully charged battery. For example, if a puff normally is held for three seconds, which is pretty common, for the above example of 475 seconds available during the full charge of the battery, it is anticipated to get 158 puffs from a full charge. Of course, this is only an estimate, as vapers vary the length of puffs, and voltage of the battery varies as it ages.
These figures help the user be able to anticipate the length of time a battery will serve them, and to determine which batteries they prefer, based on the calculations. It can also help to anticipate the average time expected to be able to use a certain battery before needing a replacement or to recharge it.
