Why Do My Cartridge And Battery Get Hot?

April 16, 2021

You may have noticed that cartridges can get hot fairly quickly after use. The first step to solving this problem is determining which part is causing the heat. In most cases, it’s a problem with the ignition coil inside the tank. Cartridges get hot because electricity travels through the coil, turning your oil into vapor.

The coil can reach temperatures of 300 °C / 570 °F or higher. The outside of the tank won’t get this hot. However, the heat is fairly concentrated and can make your device feel warm.

This is more likely to happen if you are chain vaping constantly or vaping for extended periods. Doing this does not give the coil time to cool down as temperatures get higher with every session.

The type of coil can also affect the temperature of your cartridge. These coils vary in wire diameter, cross sectional areas, wire wrapping methods, and coil resistance.  For instance, a standard Clapton coil uses a thinner gauge wire tightly wrapped around a thicker gauge core.

Cartridges that use metal vape coils within an atomizer head get hotter than standard coils. This is because the outer, thinner wire takes less current. Which then heats up quickly and is in direct contact with the already hot inner core.

American Wire Gauge System

The American Wire Gauge (AWG) system is directly related to the capacity for heating and electrical conduction. These factors determine the heat threshold potential of a device. The diameter and cross-sectional area of the metal coil determine the electrical resistance. Thus, determining the coil's capacity for heating.

A smaller diameter coil will have a higher resistance and therefore a higher capacity for heating. On the other hand, a larger diameter coil will have a lower resistance and therefore a lower capacity for heating.

Electrical conduction is another factor considered. The electrical conduction of a metal coil determines how efficiently it can transfer electrical energy into heat energy. The more conductive a metal is, the more efficiently it can transfer energy and the faster it will heat up. The size of the coil affects its electrical conduction and therefore the speed at which it heats up.

It's important to know if your coil has low or high resistivity. This will determine the capacity for temperature control which directly affects your vaping experience. There are always factors involved in each component of a vape cartridge that determine the threshold of heat output.

Batteries and Power Supplies

However, most of the time, the heat generated by the battery is not a cause for concern. It is only in rare instances that the battery itself is the source of overheating. In these cases, it is crucial to take immediate action to prevent further damage and potential safety hazards.

It is important to note that the external temperature of a cartridge battery should not exceed 60 C/140 F. As this can cause the battery to overheat and become a potential fire hazard. Additionally, the internal temperature of the battery should not surpass 78 C/172 F. As this can cause damage to the battery and potentially release harmful chemicals.

If you do notice that your battery is overheating, follow these steps in the event of overheating or malfunctioning hardware:

  1. Stop using the cartridge immediately.
  2. Move the cartridge away from flammable items.
  3. Disconnect the battery from the cartridge.
  4. Place the cartridge in a safe, open area where it can cool down.
  5. Monitor the cartridge for any signs of further overheating.
  6. Do not touch the cartridge or battery until it has cooled down completely.
  7. Check the cartridge and battery for any signs of damage.


It is always a good idea to regularly check your battery and device for any signs of overheating. This can clearly indicate a potential issue with the battery or device. You can prevent potential safety hazards and keep your device in good working order by being aware of the warning signs.

Cartridges and Coils

Another reason your cartridge and battery might be getting hot is because of coil gunk. Sometimes, gunk accumulates around the coil or within the wicking material. This prevents it from absorbing your oil, producing a dry hit. These dry hits cause the coil to overheat without producing a cloud.

There are many options to choose from when selecting an appropriate cartridge. You might want to consider substituting for a cartridge that has a ceramic coil in order to prevent coil gunk.

Ceramic coils have numerous advantages which include durability, flavor delivery, and heat resistance. They do not conduct heat and also last much longer than the common resistive wire coils.

Cheaply made cartridges not only get hot but can leech poisonous heavy metals like lead into your products. This is because lead is commonly used by vape pen manufacturers. After all, it is cheap and allows them to save money on production costs.

Use the Highest Quality Products

Check out DMLift Inc.'s zirconia ceramic cartridges if you are looking for a cartridge that does not overheat. They also eliminate the possibility of harmful metals leaching into your oils without sacrificing cloud production, flavor translation, or aesthetics. Zirconia ceramic cartridges are extremely durable.

They will not shatter if dropped and are scratch-resistant. These cartridges have microporous ceramics. They are coated with cotton, use a resistive wire, and absorb e-juice in pockets like a honeycomb.

When the wire is turned on, it heats up the ceramic element which acts as a wick. Due to its microporous structure, the oils climb through capillary action. Meaning it draws fluid upwards against gravity through a porous medium.

DMLift Inc. manufactures and sells a variety of cartridge solutions and hardware that uses the latest cutting edge technology. Our cartridges do not overheat so they can stand up to very high temperatures, greatly increasing their lifespan. The mouthpieces are made to precisely fit the natural contours of your lips. Allowing you to create an airtight seal around the tip to effortlessly take draws.

Overall, if your cartridge and battery are getting hot, it is likely due to the heat generating coil in your tank. You can address this by using our ceramic cartridges at DMLift Inc.
