E Cig Battery Guide

E Cig Battery Guide For New Vapers

Lithium-ion batteries are often referred to as Li-ion batteries. For batteries to use in mods you need to look for rechargeable Li-ion batteries.

They come in two varieties: protected and un-protected.

The protected batteries are longer because they have a circuit built into them to fail before the battery fails.

Li-ion batteries are among the most powerful rechargeable batteries available. They are made from a compound of Lithium that is flammable. A failing battery can vent dangerous gases or cause a fire.

This is why it is essential to buy the best battery you can afford and ensure that it is recharged properly.

You will have seen many stories in the media about house fires caused by e cigarette batteries – this is very rare in practice.

The following are examples of devices that also use Li-ion batteries:

  • Mobile phones
  • Laptops
  • tablets
  • digital cameras
  • camcorders
  • cordless drills
  • sanders
  • saws
  • hedge trimmers.

IMR Li-ion Batteries – Recommended

These are the recommended types for use in electronic cigarettes. They are made from a different compound compared to other Li-ion batteries, lithium and manganese. They have a lower internal resistance. This means that they stay cooler and can deliver a higher current.

IMR batteries are known as ‘safer chemistry’ batteries because they are more likely to vent gas in a fail than to burst into flames. Again, failure rate is very low.

Battery Sizes

An 18650 battery means that it is 18mm in diameter and 650mm in height. A 14500 battery means that it will be 14mm in diameter and 500mm in height and so on.

mAh

The milliampere-hour (mAh, mA.h) is the measurement of how long your battery will last in use. A higher figure means the battery will last longer. Like a car’s petrol tank, the larger it is the more fuel it will hold.

The true figure for a battery can be much less than what is printed on the side of the battery. A rule of thumb is ‘you get what you pay for’. An expensive brand will perform better, last longer and be safer in use.

The lower the resistance of your coil the ‘faster’ the energy will flow around the circuit in the mod. This means the current (amps) will be higher. It is important to know what the maximum current your battery will withstand is, this is known as the ‘continuous discharge’ value – a table of which can be found here.

Best E Cig Battery Brands

There are many cheap batteries being sold separately and with e cig starter kits. As mentioned it’s highly recommended to spend the few extra £’s and buy a known brand name.

The following are widely recommended battery brands for e cig MODS that do not have a built in battery:

It is also worth mentioning that there are many fake e cig batteries being sold so be sure to buy from a reputable vendor.

Torchy is a trusted seller by many for their e cig batteries, he sells via his store on eBay here. He also has a post here that highlights the dangers of cheap batteries.

In use

Li-ion batteries start degrading after being manufactured. They will last 2-3 years from the date of manufacture whether you use them or not. They are sensitive to high temperatures as the heat will cause them to degrade rapidly.

If you completely discharge a lithium-ion battery, it is ruined.

Use a well-known, reliable recharging unit that will keep your batteries in optimum condition and monitor that they do not overcharge.EGO Chargers, what to use

Recommend Chargers

Again there’s a lot out there but the following chargers are recommended for APV/MOD batteries:Nitecore D2 Close Up

If you are using a vape pen style e cigarette be sure to only use the charger supplied with the battery even if you have chargers that may look the same (as they often do). It also goes without saying, buy from a reputable source.

The difference between a cheap charger/battery and a quality device is literally pounds. This is not an area to try and cut corners to make savings.

Check your battery has the following:

  • Overcharge Protection
  • Over-discharge Protection
  • ROHS Certified (In The UK)

E Cig Battery Disposal

Disposal

Do not throw your old or damaged batteries into the bin, and this applies to all batteries, take them to your nearest recycling centre as they contain metals that will poison the ground if placed in land fill sites.

Battery Rules:

  • Use an IMR battery.
  • Do not use unprotected ICR batteries in a vape mod.
  • Do not carry around loose batteries in your pocket, contact with metal items such as keys and coins can cause major incidents. Always use a carry case.
  • Buy from a reputable vendor.
  • Do not overcharge.
  • Do not leave a battery charging unattended.
  • Do not allow it to run down below 3.3volts in use.
  • Do not scrimp – buy the best available.
  • Always check your resistance of your atomiser before using it.
  • If your device is getting hot stop using it and remove the battery.
  • Get rid of your old batteries at the local tip recycling collection point.
  • If you are unsure – join a vaping forum and ask a question, someone will answer it. Some popular e cig forums can be found at the bottom of this page
  • Take a look at the East Sussex Fire & Rescue Service page to see what happens when things go wrong.
