Battery Safety Guide

Introcution

So you recently purchased your first mechanical mod and then realized you had no idea that it took batteries or had no idea which batteries were going to be safe with it? Or just want to get familiar with the batterys that vaporizers use?

We will try teach you as much as we can about batteries, battery safety, ohm’s law, and how to determine how safe your coil or atomizer/clearomizer/cartomizer is for the battery you are using.

With regards to vaping, the battery is the most important item, far more important than your coil, or multiple coils if you have them. Batteries are even more important than the debate over the superiority of wick materials (cotton, organic cotton, silica, mermaid hair – whatever). So if you are looking to get into mechanical mods, or thinking about pushing the limits of your current set-up, or are completely unaware of what your battery can even handle – then this article is definitely for you.

Basic Housekeeping Rules

Do not overcharge or over-discharge.

To combat this, do not leave your batteries in any charger without supervision. Make sure that you are able to see or check on the charger every 15-30 minutes. This way when the charger indicates that the batteries have been fully charged, you can remove them from the charger. Leaving batteries in a charger all night long or longer can cause them to be overcharged, which can result in battery failure. Charging your battery over 4.25 volts can shorten its life-cycle and going over 4.5 volts can cause it to burst. Cease using your charger if this ever happens.

Our recommendation on a good charger: Nitecore D2 Charger or Nitecore D4

Recharge batteries with a resting voltage below 3.6V as soon as possible.

Leaving LiIon batteries in a discharged state will incur irreversible damage – creating a loss in capacity and a loss in cycles.

Determining the exact voltage can be tricky, without a multimeter. If you are delving into the world of mechanical mods and RBAs (Re Buildable Atomizers), or making your own coils, a multimeter is a must have device because you can use it to test your coils and your batteries. Sure, you can always use a battery tester, but the majority of battery testers are not equipped for the types of batteries that are used in mods, or even test batteries under load condition.

Do not short circuit your batteries.

Short circuiting can cause a huge surge of current that will potentially burn out your battery, damage your mod, or even your face!

Short circuits happen when the voltage from a battery is discharged through a low resistance wire at a discharge rate that exceeds the battery’s upper amp limit. Short circuiting a battery is very close to what a mechanical mod with a sub-ohm coil is doing, except you are trying to keep the resistance under the upper amp limit – there’s a fine line that you have to be careful of when sub-ohming.

Do not let your batteries touch each other or other metallic items.

Keeping your batteries loose, such as in your pockets, is a good way to have your batteries fail and seriously harm you. There are battery holders and covers to keep your batteries safe. Get some here.

Do not dispose any battery in a fire.

This is just common sense people. There are dangerous chemicals in batteries. If you try to burn your batteries they’ll release dangerous fumes and will probably explode. Do yourself, and the rest of the world, a favor by taking your old batteries to a battery recycling center.

Quick Recap

  1. Calculate your battery’s capacity in amps: capacity in mAh / 1000 = capacity in amps

  2. Calculate the maximum discharge rate if measured in C: maximum discharge rate = (battery capacity in amps) x (continuous discharge rate)

  3. Measure your battery’s volts with a multimeter

  4. Measure the Ohms of your coil and subtract .2 to account for the +/- .2 variance

  5. Calculate the discharge rate you’ll have with the coil you’ve built: battery volts / Ohms = your actual discharge rate

  6. Check to make sure that the actual discharge rate is LOWER than your battery’s maximum discharge rate.
