Guide to E Cigarette Batteries


Getting your head around e cig batteries can be one of the most daunting tasks for any new vaper, and a good battery is just as essential as a good tank or atomizer. If you’re completely new to e cigarettes, we suggest you give our beginners’ guide a quick glance over to get up to speed on why batteries are so important.
With different voltages, watts and mAhs, looking at e cig batteries can feel a little like flicking through a physics textbook, so we’ve put this guide together to help you better understand the different sorts of batteries on offer and decide which is best for you. We’ll also cover ways to extend your battery life, and take a quick look at matching voltage and resistance.
In most “ciga-like” ecigarettes, the battery is automatic, which means it only activates when you draw on the ecig. Although a little more convenient, automatic batteries do not give vapers as much control over their draws, tend not to have as long a battery life and don’t match up to the quality of many manual batteries. For this reason we’re going to be concentrating on manual batteries, as we believe they are the best option for any vaper.

Manual E Cigarette Batteries

Manual E Cigarette batteries allow users to control how long the coil is heated for, and therefore how much vapour is produced, by pressing a button to activate the battery.
Almost every manual battery on the market is turned on and off by pressing the button 5 times in quick succession. Users can then press the button again to fire up the coil and vapourise the e liquid.
Different batteries output different amounts of voltage, which essentially equates to the power sent to the coil. The higher the voltage, the more vapour is produced. Many mid-level batteries, such as the Vision Spinner 2, have variable voltages, which allow vapers to change the output of their battery. Some batteries even have variable wattages, but in the interests of preventing this guide from turning into a science lecture, for all intents and purposes they do the same thing – more wattage = more power sent to the coil.
Variable voltage is a good option for all vapers because different atomizers and e liquids respond better to different voltages. Additionally, different vapers will prefer different outputs, and a variable battery gives you complete control over your vaping experience.

Voltage and Resistance

Different atomizers have different amounts of resistance, measured in ohms. In a nutshell, the lower the resistance, the more electricity will flow into the coil. This will make the coil hotter which will in turn create more vapour. However, if you pump too much power into a coil, it can burn the wicking material, create bad tasting vapour and even damage your battery.
The higher the resistance, the less power you’ll provide the atomizer, which means that the battery will last longer, but less vapour will be produced.
For this reason, it is important that you know what ohmage your atomizer is before you set the voltage on your battery. We’ve developed this ohm/volt calculator which will tell you if your values are correct or not.

mAh and Battery Life

Most electronic cigarette batteries are measured in mAh, which stands for milli amps per hour. This is essentially a measure of how much life a battery has and how long it will last between charges. The higher the mAh, the more draws you’ll get out of your battery before it runs out.
It is hard to tell exactly how long a battery will last between charges for any individual vaper, as it is largely dependent on what voltage they use, what resistance they use and how long they draw for. As a very rough guide we estimate that:
300 mAh = 200-300 draws
650 mAh = 300-700 draws
1100 mAh = 700-900 draws
1300 mAh = 900+ draws

Maintaining your E Cig Battery

How you use and care for your battery can prolong its lifespan dramatically. Following these 6 tips will keep your battery in the best condition possible.

  1. Don’t allow your battery to fully run out of power before charging. Contrary to popular belief, it is actually better to recharge your battery from partial charge, as opposed to fully recharging it from empty.
  2. Keep the battery clean and do not allow e liquid to leak into it. Pay particular attention to the terminal where the battery connects to the clearomizer and regularly clean it out with a q tip.
  3. Store your battery in a cool, dry place. Extreme temperatures can damage your battery and reduce its lifespan.
  4. Turn battery off when not in use, to prevent accidental discharge when in your pocket or bag.
  5. Only charge your battery using the charger provided. Do not mix outputs, as this will damage your battery and can even result in fires and explosions.
  6. Do not leave your battery on charge for extended amounts of time. Most quality batteries have overcharge protection, but can still overheat. Do not leave your battery on charge overnight and do not leave it unsupervised whilst charging.

What Battery is Right for Me?

Unless you’re an experienced sub-ohm vaper, a good, mid-level variable battery will fulfill all of your needs. You want to get a battery with a voltage range somewhere in the region of 3v – 6v. For most atomizers, 5v will give plenty of power for a good vape.
