What Are Vape Batteries?

Vape batteries are rechargeable power sources used to fuel electronic cigarettes and other vaping devices. These batteries store electrical energy and release it when the device is activated, providing power to the coil to heat up the e-liquid and convert it into vapor. The power of the battery is measured in voltage, and its capacity is measured in mAh (milliampere-hours). The higher the mAh, the longer the battery will last between charges.

Most vape batteries are lithium-ion batteries due to their efficiency, high energy density, and relatively safe chemistry. Lithium-ion batteries have a high discharge rate and are capable of providing sustained power for high-wattage devices. Vape batteries are typically divided into two categories: built-in rechargeable batteries and removable rechargeable batteries.

The majority of advanced vaping devices, such as box mods and sub-ohm tanks, rely on removable batteries. These batteries offer greater flexibility, as they can be replaced or swapped out for longer vaping sessions. Built-in batteries, on the other hand, are often used in simpler pod systems and disposable e-cigarettes for ease of use.

1. 18650 Batteries

The 18650 battery is the most widely used battery in the vaping world. The name comes from its size: 18mm in diameter and 65mm in length. These batteries typically have a capacity ranging from 1800mAh to 3500mAh and a standard voltage of 3.7V.

18650 batteries are ideal for most box mods and vape mods. They strike a good balance between power output, capacity, and size. These batteries are also easily available and come in a variety of brands and specifications. If you’re using a mod that doesn’t require extremely high wattage, an 18650 battery will be a great choice.

2. 20700 Batteries

The 20700 battery is slightly larger than the 18650, measuring 20mm in diameter and 70mm in length. The extra size allows for greater capacity, with 3000mAh to 4000mAh being typical ranges. The 20700 is commonly used in mods that demand more power, such as sub-ohm devices and high-wattage box mods. With their increased capacity, these batteries provide a longer-lasting vape session compared to 18650s.

20700 batteries are also capable of handling higher discharge rates, making them a suitable choice for more powerful devices that require a higher amperage.

3. 21700 Batteries

The 21700 battery is the largest commonly used battery in the vaping industry, measuring 21mm in diameter and 70mm in length. The size allows these batteries to hold an even larger capacity, ranging from 4000mAh to 5000mAh. This makes them ideal for high-power vaping devices such as regulated mods and devices that require substantial power to operate at high wattages.

A key benefit of 21700 batteries is their ability to provide extended battery life while supporting high-power outputs without compromising performance. If you need a battery that can keep up with heavy usage or long vaping sessions, 21700 batteries are the go-to option.

4. Built-in Batteries

Built-in batteries are internal rechargeable batteries that come pre-installed in certain vaping devices, including disposable pod systems and starter kits. These batteries are non-removable, which means once they lose their charge or degrade in performance, the entire device needs to be replaced. Built-in batteries are typically smaller in capacity compared to removable batteries but are convenient because they eliminate the need for carrying spare batteries.

Although they are typically less powerful than removable batteries, built-in batteries work well for beginner or intermediate vapers who prefer simplicity and ease of use.

How Vape Batteries Work

Vape batteries work by converting stored electrical energy into power that is used to heat the coil in the atomizer. When the user presses the firing button on their device, the battery sends a surge of power to the coil. The coil then heats up and vaporizes the e-liquid, allowing the user to inhale the vapor.

The performance of the battery is determined by several factors:

• Voltage: Vape batteries typically operate at 3.7V, but some advanced mods may run at higher voltages. A higher voltage can provide more power, resulting in increased vapor production and a hotter vape.
• Capacity (mAh): The capacity of a battery determines how long it will last before needing to be recharged. The higher the capacity, the longer the battery life. Higher-capacity batteries are ideal for long sessions or high-power devices.
• Discharge Rate: This refers to how quickly a battery can release its stored energy without overheating or causing damage. High-drain batteries with a high C rating are required for devices that use higher wattage.

How to Choose the Right Vape Battery

Choosing the right vape battery is crucial to getting the best performance from your device while ensuring safety. Here are some factors to consider when selecting a vape battery:
