General Battery Safety

Battery Safety is extremely important. To use Electronic Cigarettes safely, you will need a basic understanding of Battery Safety and Maintenance. It’s vitally important that you charge and store your batteries in a safe and responsible way in order to avoid explosions, fire hazards or personal injury. When used correctly, even the most powerful batteries are completely safe so there’s no need to worry, but it’s best to be informed so you can keep vaping safely.

DO NOT store loose batteries in your bag or pocket.
Contact with coins could complete the circuit leading to risk of explosion.

DO NOT use a battery if there are signs of damage or wear.
Any corrosion, dents, bends, leaks, scratches or a ripped plastic outer cover.

DO NOT store batteries in areas with fluctuating temperatures.
It’s unlikely to pose risks while being charged but it should still be monitored.

DO NOT charge your batteries on a flammable surface.
Keep away from flammable materials. The increased heat could cause a fire.

DO NOT allow the battery to come into contact with water.
Avoid leaving them in a humid environment for long periods of time.

DO NOT mix and match batteries.
Unless specifically stated that this is safe to do so from the manufacturer.

DO NOT keep your batteries if they become unusually hot.
Dispose of batteries that show any signs of wear due to excessive heat.

DO NOT use batteries that provide a lower power output than your device.
Ensure your batteries output matches the coil and tank have.

Non-Removable (internal) Battery Safety

Internal Batteries are used in Vape Pens, Starter Kits and POD Systems. The battery is charged through a Micro-USB port on the device itself. These batteries pose a much lower risk of problems since they’re self-contained inside the kit, but you still have to be careful when charging the device to ensure there are no issues.

DO NOT charge your device in a mains charger.
Charge your device through your laptop or computer’s USB port.

DO NOT continue using the device if the battery doesn’t hold charge.
This is a sign your battery is worn and is close to needing to be replaced.

DO NOT use if the battery is outputting more wattage than expected.
Or if it’s much hotter than usual. This could be a sign your battery is damaged.

DO NOT increase the wattage past the recommended limits.
The recommended wattage for your device is shown on your directly on your coils.

DO NOT keep your device on while you’re not using it.
Avoid accidental misfires which help keep your batteries in top condition for longer.

Removable IMR Battery Safety (High Powered Batteries)

High power vape kits (Sub Ohm or Rebuildable) usually require one or two high powered batteries, such as the 18650, 20700 or 21700. These IMR Batteries (Lithium-ion Manganese Rechargeable) can be charged in either a charging dock, or directly through the device itself with the use of a Micro-USB cable. High powered mods have several safety features to mitigate the possibility of overcharging, so if you choose to charge through the device itself please be aware you won’t be able to achieve 100% capacity. It’s therefore recommended, but not required, to charge these batteries in a charging dock.

These batteries are extremely powerful and can be extremely dangerous if not cared for correctly. Vapoholic therefore do not recommend Sub Ohm devices to new vapers, unless they have advanced knowledge of battery safety or are willing to learn before purchasing. Incorrect usage of these batteries could lead to fires, explosions or personal injury so it is essential you follow the below guidelines to avoid any unforeseen accidents.

DO NOT leave IMR batteries unattended while charing.
This includes batteries charging directly in the vape mod, but it’s most important if using a charging dock. These batteries should be frequently monitored while charging.

DO NOT store IMR batteries loose in your pocket or bag.
Coins or other metallic items can come into contact with the terminal (the positive and negative sides) and complete the circuit, causing an explosion, fire and personal injury.

DO NOT use IMR batteries that show ANY signs of damage.
Check for signs of melting or bubbling around the sleeve (the cover over the battery). If you see any signs of damage, dispose of the battery immediately and do not continue using.

DO NOT use IMR batteries that have a torn or damaged sleeve.
If you notice any damage to the sleeve, dispose of the battery immediately. A damaged sleeve can lead to your battery swelling, which increases the risk of fires and explosions.

DO NOT exceed power limits recommended by your coil.
Keep the wattage of your device within the recommended maximum. This information is found directly on the side of all coils and shows the recommended and maximum wattage.

DO NOT use under-powered batteries in your device.
For example, if you have a 250w device but your batteries cannot output the required wattage, the battery could either fail or become damaged and unstable.

What is an Ohm?

An ohm is a measurement of electrical resistance. The resistance of a coil dictates which E Liquid it can use, and what kind of vaping experience you’ll have. Sub Ohm coils (coils with a resistance less than 1ohm) are designed for Mouth to Lung Vapers as the low resistance allows a lot more vapour to be inhaled. These coils work best with thicker E Liquids (70/30 for example) as thinner E Liquids will simply leak through the coil due to the low resistance.

Coils with a resistance above 1ohm are designed for Mouth to Lung vapers, this is because the ‘draw’ is much harder which is more akin to how most people smoke tobacco. These coils work best with thinner E Liquids (50/50 for example), using thicker E Liquids will result in coils burning out faster due to the higher resistance of the coil.

What does Wattage mean?

A Watt is a unit of power, or an amount of electrical power expressed in watts. Your coils will show a wattage range for optimal performance (for example, 30w to 50w). The lower wattage is the minimum powered required for the coil to work correctly, while the higher wattage is the maximum wattage the coil can take. You should never use a higher wattage than your coil specifies.

What is an Ampere/AMP?

The ampere is the base unit of electric current. This unit measures the speed in which an electric current flows. Unless you’re building your own coils, you don’t need to concern yourself too much with a battery’s AMP. All Sub Ohm devices/coils are designed to work with 18650, 20700 or 21700 batteries which have the ideal power and AMP requirements for your device.

If you do build your own coils, knowledge of Ohms Law is essential and the usage of an Ohms Law Calculator is heavily recommended. This way you can calculate the Wattage, Voltage and Ampere you would need depending on the resistance of your coil. Too low, the mod won’t work. Too high, you run the risk of fire hazards and explosions.
