Vape Battery Safety September 13 2015, 5 Comments


While vaping is generally an extremely safe hobby to partake in, it can be dangerous if you choose to ignore basic battery safety advice. When vaping with unprotected lithium-ion batteries (aka the type of battery that most mods utilize), it’s extremely important to follow proper safety precautions to help avoid serious injury and damage to property.

General Battery Safety Guidelines

If the resting voltage is below 3.6V, recharge as soon as you can

To determine the exact voltage of your battery, it’s important to purchase a multimeter. It’s extremely important if you’re using mechanical mods and RDA’s, because it will allow you to test your coils and batteries to ensure that you’re not doing anything dangerous. While we don’t currently carry multimeters at MintyVapes, they are available for relatively cheap at places like Amazon.

If you leave your lithium-ion batteries in a discharged state, it can lead to a loss in capacity and a loss in cycles, and potentially permanent damage.

Do not overcharge your batteries

If lithium-ion batteries are overcharged, you run the risk of severely limiting the lifecycle of the batteries or, in extreme cases, you can cause them to burst. It’s extremely important to never leave your charging batteries unattended, and to make sure to check on them every 15-20 minutes so you can remove them once the charger indicates that they’re fully charged.

We highly recommend using the Nitecore Intellicharger for optimal results.

Do not short-circuit your batteries

This is mainly a concern for sub-ohm vapers who are using mechanical mods. When sub-ohming, you are essentially riding the lower limit of your batteries at a level where they are very close to short-circuiting. Be very careful to not exceed your batteries upper amp limit.

Don’t let loose batteries touch each other or metallic objects

Keeping loose batteries mixed together or mixed with other metallic objects has been known to cause a few serious fires. If you keep your loose batteries in your pocket alongside keys or change you can start a fire that will cause serious burns that will require extensive medical treatment. Make sure you get some kind of battery carrying case.

Don’t set your batteries on fire

This falls into the realm of common-sense, but it needs to be said anyway. If you need to get rid of your batteries, take them to some sort of recycling center, and DO NOT try to dispose of them in fire. The dangerous chemicals in the battery will explode.

Stay Under Your Battery’s Max Discharge Rate

Determining max discharge rate

Most newer batteries will list the maximum discharge rate in terms of amps (e.g. 15 amps, 20 amps, etc.) You need to make sure that your actual discharge rate is under the max discharge rate to ensure proper safety.

How to determine actual discharge rate

Here is a simple way to determine your actual discharge rate:


Use a multimeter to determine your voltage rate, and then divide that by the amount of Ohms of your coil. For example, your multimeter says that your voltage is at 4 volts. You’re using a coil that is at 0.4 Ohms. That means that you’re at 10 amps. If you’re battery is rated at 10 amps or above, you’re in the clear. If not, you need to build another coil (Inconvenient, but necessary.)

Now you know the most important basic safety precautions when vaping with lithium-ion batteries. It’s very important for all mod vapers to fully understand this material BEFORE you start vaping, especially if you’re planning on sub-ohming or using a mechanical mod.
