Vape Mods & Batteries

The battery is the most important part of an e-cig. It’s what powers the device and controls how much vapour your kit produces. There are two kinds of batteries, internal and removable. Internal battery e-cigs are also called mods. The difference between a mod and a kit is that it doesn’t come with a tank. It’s important to look after your batteries and mods, as improper use can affect how your kit performs and in the worst-case scenario can cause harm.

Mods

The mod is the main part of your kit. It contains the battery and provides power to your tank and coils. Mods can have a wide variety of features such as: variable wattage, multiple power settings and fire buttons. They also have built-in safety features such as surge protection or fire cut off. Mods can contain both types of battery.

Internal batteries are built into your kit, and you charge them through the charging port. The major benefit of them is that you don’t have to worry about carrying around extra batteries. The downside is that batteries degrade over time, usually resulting in them lasting for less and less time. With an internal battery, you have to replace the full kit when it doesn’t hold its charge anymore. Also, if your battery runs out when you’re out and about, then you’ll have to find somewhere to charge your device.

Some examples of internal battery mods include: the Mini iStick 20w Mod, iStick i80 Mod and iStick Power 2.

Removable Batteries

Removable batteries can be removed from your kit, hence the name. The best part about them is that you can carry around full charged spares. You can then replace them if they die whilst you’re away from a charger. Also, when the batteries aren’t able to hold charge anymore, you can simply replace them, which is much more cost-effective. The only downside to removable batteries is that if you’re carrying around extras, they take up space in your pockets or bag.

18650s

18650s are the most common type of removable battery. The most common battery capacities in this size are 2600mAh like the Golisi S26, and 3000mAh like the Golisi S30.

21700s

21700 batteries are larger than the 18650s, both in size and battery capacity. They’re often, 4000mAh and provide a huge battery life in a smaller mod. Currently, we don’t sell any devices that use this battery, but we still sell Avatar 21700s if you have a mod that can use them.

Battery Safety

It’s very important to look after your batteries, especially if you’re using removable ones. Here’s some handy battery safety information, so you can get the most out of your batteries.

  • Make sure that the packaging has the CE and ROHS safety logos.
  • Don’t keep or charge your batteries in extreme temperatures.
  • Make sure the charging equipment and batteries aren’t damaged. This includes damaged wraps on removable batteries and any signs of rust or leaking.
  • Don’t mix brands of batteries and chargers, unless you can find out if they’re compatible.
  • Always charge your batteries by following the product instruction manual.
  • Keep an eye on any charging batteries and don’t charge them near anything flammable.
  • Don’t put batteries into water.
  • Always keep loose batteries in a plastic box or silicone sleeve. If they contact metal and complete a circuit, they will begin to heat up, which could lead to something more serious.

Most importantly, you need to dispose of your batteries properly at a battery recycling point. If you have an internal battery, then the TECC store and Totally Wicked stores will accept them for disposal.
