Vape Batteries & Coil Safety
Safety is paramount when it comes to vape batteries and coils. Most rebuildable devices use replaceable vape batteries and either store-bought or rebuildable coils that you can put together at home.
Unlike self-contained devices such as pod vape kits, vape batteries and coils are far more complicated and require a lot more care, so a lot more knowledge is required as a result. But how do you care for them? And what are the do's and don'ts when it comes to these products? Well, Ecigone is here to answer those questions and more, so read on!
Battery Types and Voltages
Vapes can contain one of three battery variations:
Single-Use Batteries—These vape batteries are normally found in disposable vapes and are built into the device. They cannot be recharged, and once they've been depleted, the whole device must be thrown away.
Internal Batteries—Similar to single-use vape batteries, internal batteries are built into the device but can be recharged, extending their usability. You'll typically find these types of batteries in pod kits.
External Batteries—External vape batteries can be removed from the device and are more for experienced vapers. They can be found in advanced vape kits and vape mods like sub-ohm devices.
Picking Battery Voltage
Most beginner vapers won't need to worry about the voltage of their devices since the batteries are usually integrated into beginner kits and already have the correct voltage. Experience vapers using external vape batteries must pay close attention to voltage to ensure they get the proper amount for their device.
Most modern advanced vape kits have built-in safety features to prevent issues like low voltage, so if a battery's voltage is too low for the device it's used with, the kit simply won't fire. External batteries commonly come in 18650, 20700, and 21700mAh, with a voltage range of between 3.7V and a max voltage of 4.2V. Check what voltage your device can take before purchasing a battery by checking the manual that came with your device.
Battery Capacity
When it comes to vape batteries, wattage matters more than voltage. Wattage measures the battery's power, and the capacity is how much power it can hold. The mAh rating simply shows how long the battery can last before it needs to be charged again.
However, a few factors can affect the output. For example, a 1000mAh battery used in a device with a low wattage could last the same length as a 2000mAh battery used in a high-wattage device. This is why you'll often find lower-capacity batteries in lower-wattage kits than in higher-wattage kits.
Vape Batteries and How to Care For Them
Replaceable vape batteries are very different from the built-in ones you'd find in a pod kit. For one, they can be removed, which can be helpful if your batteries have a problem. However, because they can be removed, they're much more prone to damage, so we'd recommend storing your spare batteries in a cover or a holder to prevent damage from them touching each other and other metallic objects.
When inserting your batteries into your device, ensure they're the right way around to prevent venting. Some devices have reverse polarity protection, but all the same, ensure you're not inserting the vape batteries backwards.
When you're recharging your vape batteries, check on them regularly, and as soon as they're done charging, remove them from the charger. Always charge them on a fire-proof surface, and never leave them charging unattended overnight.
The chemicals in these vape batteries can be dangerous when mistreated, so it's important to store them away from extreme temperatures—especially fire. It's also a good idea to check your vape batteries regularly for any dents or damage, and if any are found, do not use them again.
Finally, be careful when using Lithium-Ion vape batteries. Before using them, make sure you have sufficient knowledge of charging, discharging, and assembly.

Vape Batteries Do's & Don'ts
There is a lot of key information needed when using vape batteries, especially if you're new to them. That's why we've put together a hand list of do's and do n'ts to help you on your way.
DO:
Use static-proof containers to store your spare batteries.
Remove your batteries from the charger once charging is complete.
Use the correctly supplied charging cable.
Charge on a hard, fire-proof surface.
Turn off the battery when it's not in use.
Clean the battery and its terminals if dirty.
Put your batteries in a zip lock bag with rice for 48hrs. If they get wet, dry them out thoroughly.
Make sure the battery orientation is correct before use.
DON'T:
Store your batteries with metal objects.
Charge the batteries unattended.
Over-tighten the battery when attaching it to the atomiser.
Use damaged vape batteries or vape batteries with damaged wraps.
Expose vape batteries to the sun or extreme temperatures.
Leave vape batteries exposed in cars or other outside areas.
Allow your vape batteries to come into contact with water or other liquids.
Push the vape batteries beyond their safe limits.

Rebuildable Atomisers, Coils & Wicks
Knowing how to properly use rebuildable atomisers, coils, and wicks is just as important as knowing how to use vape batteries. These products are designed for experienced vapers with prior knowledge of basic electronics.
Someone cannot safely use these products without knowing when a metre should be used or how electronics work for various reasons:
Rebuildable coils/wicks MUST be tested carefully with a metre before use.
The user may be at risk of injury if they are not tested.
They must be tested as a faulty coil/wick WILL blow out electronic devices.
Before new coils/wicks are used for recreational use, they must first be tested on a strong basic vape mod or, even better, a testing rig to verify their safety.
Never use a new coil/wick on a device that is proven to be unsafe.
It is a known issue that these materials can destroy electronic devices.
Sub-Ohm Tanks & Coils
If you opt for a sub-ohm tank and coil, it's recommended that you are already an experienced vaper. As with these more advanced devices, extra caution must be taken when using them. Do note that sub-ohm tanks and atomisers will only work on mechanical or regulated mods that can utilise them.
For example, if you decide to use a 0.2 Ohm coil, your device must fire at 0.2 Ohms or lower, so it's best to do some thorough research before purchasing. You must also be sure that your batteries can be used in a sub-ohm device and with sub-ohm coils and atomisers.
If you are unsure what wattage or resistance you should use, use an Ohms Law calculator to check your amps. It's better to be safe than sorry!
How do Single-Use Batteries Work?
Disposable vapes use single-use batteries, which are non-rechargeable, unlike most other vape batteries, which are rechargeable. These batteries are made to last approximately the same amount of time as the e-liquid inside the device, and because disposable vapes have a closed system, the battery cannot be accessed.
Once the battery runs out, that's it - the device will no longer work. However, it still has a battery inside, so it can't be disposed of in regular household waste. You must recycle disposable vapes at special facilities that handle electronics or put them in battery bins outside most supermarkets or with the WEEE (Waste Electrical and Electronic Equipment) for roadside collection.
Tips
New users will understandably be excited about using their new high-powered devices. Still, along with all the electronic knowledge you now have, choosing the correct e-liquid for your device is essential. We recommend using an e-liquid with 6 mg of nicotine or less, as sub-ohm atomisers produce a much harsher throat hit than their low-powered cousins. Using higher than 6 mg will result in a burnt taste or be harsh - something you don't want!
Vape Responsibly
Well, there you have it—a crash course on how to properly care for your vape batteries and coils. They're definitely a product best suited to experienced vapers, but if you want to give them a go, there are plenty of helpful tutorials online and on YouTube to help you get a leg up.
Whichever vaping path you decide to go down, remember this - vape responsibly, do your research and above all, enjoy yourself.
