How Electronic Cigarettes Work
Electronic cigarettes, commonly known as E-Cigarettes and E Cigs, have revolutionised the way people consume nicotine. Unlike traditional cigarettes, E-Cigarettes work by heating a liquid containing nicotine, known as e-liquid, into an aerosol or ‘vapour’ which is then inhaled by the user (1). This process mimics the sensation of smoking without the harmful combustion of tobacco, making it a popular alternative for those looking to quit smoking.
At the heart of this process lies the electronic cigarette battery. The battery supplies the power needed to heat the coil or atomizer, which in turn heats up the e-liquid. This battery-powered mechanism is what transforms the e-liquid into the inhalable vapour, delivering nicotine to the lungs much like a traditional cigarette but with significantly reduced harm. Public Health England has found e-cigarettes to be 95% less harmful than tobacco cigarettes (2), making them a safer choice for nicotine consumption.
The battery’s role is vital; without it, the coil can’t heat up, leading to a poor vaping experience. Hence, choosing the right E-Cig battery is key to both performance and satisfaction.
Why Electronic Cigarette Batteries Matter
The quality of your vape battery directly affects your device’s performance and longevity. A dependable battery ensures consistent vapour production and satisfying puffs, significantly influencing user satisfaction.
An electronic cigarette battery’s main role is to power the device’s heating element, transforming e-liquid into vapour. Even the best e-liquid and advanced devices can’t perform well without a reliable battery!
The battery type also affects ease of use and safety. Removable batteries allow for quick swaps, minimising downtime, while built-in batteries offer a streamlined experience but require charging and, eventually, replacement when they fail.
Types of E-Cigarette Batteries
E-cigarette batteries come in various types, each with its own set of advantages and drawbacks. The most commonly used type is the lithium-ion E Cigarette battery, known for its rechargeable nature and superior energy density. These batteries are not only reliable but also environmentally friendly, making them a popular choice among vapers.
The 18650 battery is popular in vape mods for its standard size and high capacity, offering extended usage and robust performance. Choosing the right battery type is crucial for ease of use and safety, so be sure to buy from reputable retailers to avoid counterfeit batteries.
Besides lithium-ion batteries, other types are used in E-Cigarettes. Some devices have replaceable vape batteries compatible with specific vapes, offering flexibility. Knowing your options helps you make informed choices and improve your vaping experience.
Best Built-In Battery Devices
Devices with built-in batteries offer a different set of advantages compared to those with removable batteries. Typically, they are less expensive upfront and provide a more streamlined user experience. However, once the built-in battery fails, the entire device must be replaced, which can be a drawback.
One of the standout devices in this category is the Innokin Trine Q. This device features a built-in 1050 mAh battery that supports a maximum output of 21W, making it ideal for consistent vaping experiences. The Trine Q also offers a rapid charging option through a USB Type-C port, catering to users who require quick battery replenishment.
Another notable feature of the Trine Q is its auto-adjusting power function, which optimises the wattage based on the coil resistance used. This ensures that you get the best possible performance from your device, regardless of the coil you’re using. With multiple coil options available, the Trine Q caters to both mouth-to-lung and restricted-direct-to-lung vaping styles.
A less-appreciated type of vape with a built-in battery are the disposable vapes, set to be banned in the UK from June 2025. These vapes are not environmentally friendly as their sealed nature makes it hard to recycle them, and many end up in general waste. This is a travesty as an Oxford study found that the batteries in disposables could be charged and used up to 700 times (3), when they are being thrown away after a single use.
SMOKO E-Cigs and Vapes
At SMOKO, we believe in providing a seamless, hassle-free vaping experience. For this reason, our devices use built-in rechargeable batteries that can be used month after month. Utilising lithium-ion, SMOKO E-Cigs and Vapes provide a convenient option that eliminates the need for extra bits and pieces. All you need is your charged SMOKO battery and your SMOKO refill and you're all set!

With the SMOKO E-Cigarette, our cigalike vape batteries are designed to look like the tobacco part of the cigarette, while the refills look like the filter end. Designed to look and feel as close to a cigarette as possible, this vape has been a favourite of SMOKO customers for over 10 years!

The SMOKO VAPE POD features a more modern design; utilising a diamond shape cross-section that allows a neutral mouth position on the refill. These are not refillable pods, but pre filled pods containing our great-tasting UK-made e-liquid, like all our devices, held to the highest standards set out by the TRPR and TPD regulations and submitted to the UK's MHRA for approval.

Finally, the new SMOKO VAPE MAX features the largest vape battery capacity for all SMOKO Vapes. Designed to look like a typical cylindrical disposable vape - but, importantly, uses pre filled pods and rechargeable batteries - the refills contain 2ml of e-liquid and the VAPE MAX battery will see you through the whole pod!
Top Removable Battery Options for Vape Mods
What are Vape Mods?
Vape mods are more advanced vapes that offer control over things like wattage and temperature to tailor the vaping experience. These devices are typically more powerful than devices with built-built in batteries, to allow users to tailor the power settings to their choice of coil set-up used in their vape mods.
This customisability allows users to mould the function of their device to their e-liquid in order to create a specific vaping experience. The drawbacks to vape mods is that they require more maintenance than prefilled vapes. Everything from checking the vape housing and vape batteries for damage, to cleaning your tank between uses, and checking the condition of your coils is essential for a safe vaping experience. This extra time needed for maintenance and the necessity for spare parts makes prefilled vapes an appealing choice, where all you need is a new refill and a charged battery!

Removable Battery Options for Vape Mods
Removable batteries offer several advantages, including the ability to replace a dead battery with a fully charged one, thereby eliminating the potential waiting for rechargeable devices. Here are some top-rated removable battery options for vape mods:
The Sinowatt 25SP 18650 battery is renowned for its reliability and high performance, making it a popular choice among vapers. Priced at approximately £4.25, it offers excellent value for money. Another great option is the Vapcell K25 18650, which boasts a capacity of 2500mAh and is priced at £4.95 for a single unit. This battery is known for its durability and consistent performance.
For those looking for even greater capacity, the Molicel P28A 18650 battery is an excellent choice. With a capacity of 2800mAh, it provides extended usage times and is priced at £7.95. This battery is ideal for heavy vapers who need a reliable power source to keep up with their vaping habits.
Each battery offers unique advantages, and your choice should match your needs and preferences. Whether you value capacity or performance, there’s a removable battery to fit your requirements.
How to Choose the Right E-Cig Battery
Selecting the right e-cig battery ensures safety and optimal performance. Battery sizes and capacities affect usage times and power output, with larger batteries often offering longer use and higher mAh values indicating greater capacity.
For devices with removable batteries, swapping dead batteries for charged ones minimises downtime. Just be sure to choose a battery compatible with your device for safety and optimal performance.
Also, make sure you buy batteries from reputable suppliers to ensure safety and compatibility and to avoid counterfeit batteries. While built-in batteries usually limit power outputs to around 100W, suitable for most vapers, high-powered setups often use removable batteries that can reach up to 230W - so it is important to avoid counterfeit batteries as they compromise on quality, durability and safety.

Maintaining Your E-Cig Batteries
Spending the time maintaining your e-cig batteries ensures safety and longevity. Batteries with built-in safety features prevent issues like overheating and short circuits. Regularly check external batteries for wear and dispose of them if damaged.
Prevent overcharging by unplugging batteries once fully charged to avoid deterioration. As overcharging reduces battery lifespan, it's important to monitor the process and unplug when completely charged. Avoid using the device while charging to prevent excessive heat and potential failure.
Storing vape batteries in their original case or a protective pouch for safety and cleanliness is a great idea. Keep them in a cool, dry place away from extreme temperatures and sunlight to prevent overheating (5). For the more fastidious vapers among you, marking purchase dates can help you track the lifespan of the batteries and keep batches together so you know which batteries you are using and when.
Finally: be sure to regularly clean terminals to ensure proper connection for the electrical contacts and reduce the risk of corrosion.
Charging and Replacing E-Cig Batteries

Proper charging and timely replacement of e-cig batteries ensures an optimal vaping performance. Always use the charger provided with your device to prevent damage. Incompatible chargers can cause suboptimal charging and potential harm to the battery.
Watch for warning signs like diminished charging capacity and longer recharge times to know when to replace e-cig batteries. Monitoring these signs helps maintain a consistent vaping experience without interruptions.
