Mods & Batteries

The battery is the most integral part of an electronic cigarette. It’s responsible for regulating how much vapour the device produces. There are two types of battery, integrated and removable. Internal battery devices are also referred to as mods. The key difference between a mod and a kit is that a tank isn’t included. It’s important to maintain your batteries and mods, as improper use can impact how your device performs and cause further issues.

The mod is the main part of your device. It houses the battery and provides power to your tank and coils. Mods can have a wide variety of helpful features including: adjustable power settings and different fire modes. There are also have integrated safety features such as surge protection or overheat protection. Mods can contain either type of battery.

Internal batteries are integrated into the device and are charged through a USB port using a provided cable. The key benefit of them is that carrying extra batteries is unnecessary. The downside is that an internal battery requires replacing the full kit when it no longer holds its charge. Also, the batteries cannot be replaced, resulting in having to find a power outlet to charge the device.

The only mod that is sold separately is the EXCEED D19 battery.

Removable Batteries

Removable batteries are self-explanatory. They are usually 18650 or 21700 sized batteries that can be removed from your device. The main benefit to these is the ability to replace them on the go with fully charged spares. Another plus is that when the battery starts to degrade, it can simply be replaced. This allows you to keep your mod, reducing the cost of a replacement.


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


21700 batteries are larger in both size and capacity than the 18650s. They’re often 4000mAh. Currently, there aren’t any devices that utilise these batteries, however you can still purchase the Avatar 21700 if you already have a device that uses them.

Battery Safety

Battery maintenance is one of the most important duties as a vaper. Below is some battery safety information to help aid in this task.

  • Ensure the packaging has the CE and ROHS safety logos.
  • Avoid storing or charging your batteries in extreme temperatures.
  • Ensure the charging equipment and batteries aren’t damaged. This includes damaged wraps on removable batteries and any signs of rust or leaking.
  • Ensure the batteries and chargers are the same brand, unless you can find out if they’re compatible.
  • Always charge your batteries as indicated in the product instruction manual.
  • Monitor charging batteries and don’t charge them near anything flammable.
  • Don’t submerge batteries in water.
  • Always store loose batteries in a plastic box or silicone sleeve. If they complete a circuit by contacting metal, they will begin to heat up and could lead to a more serious failure.

Most importantly, you need to dispose of your batteries responsibly at a battery recycling point. Internal batteries can be recycled at the TECC store or Totally Wicked stores.
