Battery Safety: Identifying Your Battery

Battery Safety


Batteries come in all shapes and sizes. You can head on over to Wikipedia and see for yourself all the different cell sizes that are available to consumers. What we deal with in electronic cigarettes are what we call “lithium-ion rechargeable” batteries and they are numbered by their size (example: 18650 is 18mm in diameter and 65mm in height, the 0 stands for cylindrical) which battery you choose depends on your mod whether it is a mechanical (mech) mod or a regulated device (APV) and the size it will accept.

The batteries used in electronic cigarettes vary in size from 10440 to 26650 in this blog we will focus on the 18650 size since it is the most widely used battery.

You can see some clues as to what size battery we have, “BRC 18560 3000mah.” This is the first step in identifying your battery, and probably the most important. Buying the wrong size battery just won’t work on your device.


The manufacturer is also a vital subject to consider when purchasing batteries. Most of us have heard of “inflated numbers, ” and in the battery market, we see it a lot of this. Some manufacturers are not as forthcoming as we would like them to be.

To someone that doesn’t know much about batterie, this might look like an awesome buy, but looks can be deceiving since this battery’s actual specs are 2600mah. Do you trust this battery now?

Rewrapping is a process when an aftermarket company takes a working cell from the original manufacturer and rewraps the label with their branding.

This battery is a rewrap of another big battery that we will look at on this journey. Do we trust companies that rewrap batteries? That is up to you to decide especially after researching.

There have been a lot of companies that have sprung up overnight with batteries marketed towards vapors (i.e., Vamped, SubOhmCell, etc.). These batteries are all rewrapped of open cells we already use, mostly the LG HE2. Keep in mind that battery factories are expensive operations and they don’t appear overnight, and these are mostly gimmicks with inflated numbers!


This will be a quick entry into specs. I’ll be explaining what these numbers and information mean in another entry.

When we find a battery on a website that we are looking to buy information will flood us.

There are a lot of numbers and symbols we might not all understand. Hopefully, this blog will help you understand some of these numbers in an attempt to make your vaping experience a lot safer.

A couple of important information we will be looking at are:

  • Capacity
  • Max Continuous Discharging Current
  • Discharge cut-off voltage
  • Resistance
  • Battery chemistry: IMR or ICR?
  • Pulse ratings

We as vapors that get into devices that require and aftermarket battery from a company HAVE to know what the specifications and limits of our batteries are. You, your family, and the people around you shouldn’t be in danger because you don’t know what you’re doing. These batteries can be dangerous if we are not careful and mindful of their limits.

Thank you and vape safe!
