What Makes the 18650 Battery Different?

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.

Tips for Choosing the Best High Drain 18650 Battery for You

As you browse our selection of batteries, there are a few different things to keep in mind to help you find the best 18650 battery for vaping the way you want.

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. Then, it is critical to look at the max amps rating, because it should match with your specific vaping device. Failing to choose the correct max amps rating is not only a performance issue, it is a safety issue.

If you have a multi-battery mod, you should “pair” your batteries, which means purchasing two batteries at the same time that have matching sizes and amperage levels. Doing so will ensure an even draw throughout the lifespan of the battery and help you avoid short circuits.

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.

Simple Ways to Maximize the Life of Your 18650 High Drain Battery

If you want your new purchase lasts as long as possible, there's a few things you can do. First, make it a habit to check the appearance of your batteries. They should be free of dents and damaged wrap, as these issues can affect performance. Avoid dropping your batteries too, because the impact can lead to damage.

Additionally, make sure you are charging them properly. Use an appropriate charging device that is designed for your specific device, not a cheaply-made aftermarket one.

Finally, if you are keeping extra batteries on hand (as you should), be sure to store them correctly. Keep the batteries in a cool, dark place, so they aren't ever sitting in direct sunlight.

These easy tips can help you keep your batteries healthy and functioning correctly during their lifespan.
