First, look at the mAh number, which stands for the milliamp hour. This number is related to the capacity of the battery, which can help you determine how long you can use it before reloading with a battery charger. Avoid cheaply-made batteries because saving a few dollars isn’t worth endangering your safety or the health of your vape device. Buying unregulated batteries from an unfamiliar source means that you can’t be quite sure what you are receiving. Instead, buy your 18650 batteries – and all vape products, for that matter – from a reputable, well-known name in the industry.

Although a high drain battery may look strikingly similar to your typical household battery, it is actually much different. Due to the high wattage capabilities of modern-day variably-wattage vape mods, the 18650 battery was created in order to provide a safe and efficient power source. There are a few different size options when it comes to high drain batteries, but 18650s are the size you will see most often.

For mods that are high wattage or low resistance, a high drain battery is required to meet the correct amperage of the device. A mismatched battery can cause short circuits, or worse, serious safety hazards. 18650 batteries are designed to meet the very specific needs of these vape devices. These batteries are able to draw all the way up to the maximum amperage rating of the device throughout the entire discharge cycle of the battery, providing consistent performance and allowing you to vape at your preferred wattage and temperature safely. This consistency continues through the life of the battery, until replacement, so you don’t have to worry about decreased safety and performance as the battery ages.

Most vapes typically use rechargeable lithium-ion batteries, with the most common types being 18650, 21700, and 20700 batteries. These high-performance vape batteries provide the necessary power to heat the coils and vaporize the e-liquid, offering a satisfying vaping experience. You’ll find the best batteries in the game when you browse VaporFi’s vast collection!

The lifespan of a vape battery can vary depending on usage, maintenance, and battery quality. On average, rechargeable vape batteries like 18650, 21700, and 20700 batteries can last for several hundred charge cycles before experiencing a decline in performance. Regularly inspecting and properly maintaining the battery can help prolong its lifespan.

If you notice a significant decrease in battery life, decreased vapor production, or if the battery gets excessively hot during use, it might be an indication of a bad vape battery. Additionally, if the battery does not hold a charge or if there are signs of damage like leakage or bulging, it's essential to replace the battery immediately to avoid potential safety risks.

The main difference between 18650 and 21700 batteries lies in their size and capacity. 21700 batteries are larger and have a higher capacity than 18650 batteries, which means they can hold more power and potentially provide longer vaping sessions between charges. Some advanced vape devices may be compatible with both battery types, giving vapers the option to choose based on their preferences and performance needs.
