Vape Batteries

Here at Express Highs we pride ourselves in carrying everything you need to get vaping fast. In fact we want to be the very best place for anyone to buy vaporizers or accessories in the United Kingdom. We offer great prices, fantastic selection and quick shipping anywhere in the United Kingdom on the vaporizer and other head shop products that you need! Perhaps the most important accessory is the battery on your vape. Without it, you’ve got no power to produce clouds of any size. While there are some proprietary battery sizes for certain vapes (and we carry many of those), there are two main sizes of batteries that go into the vast majority of models with replaceable batteries. Let’s talk about them. 

Two popular battery types have emerged as favorites among vape enthusiasts: 21700 and 18650. While both serve the same purpose, powering your vaporizer, they differ in several key aspects. Let’s dive into a few of those differences now, and maybe it will help you figure out which kind of vaporizer battery you want in the future. We know that you’re spending a lot of money on your vaporizer purchase, so it’s wise to make sure you find the battery size that strikes the correct balance between power, longevity and size. 

At first glance, the primary distinction between 21700 and 18650 batteries lies in their physical dimensions. The 18650 battery, named after its 18mm diameter and 65mm length, has been the standard for vaporizers and other portable devices for years. In contrast, the 21700 battery boasts a slightly larger diameter of 21mm, while maintaining a similar length of 70mm. This increased size allows for a higher energy storage capacity.

Capacity is an important factor in determining the overall performance of a vaporizer. The 18650 battery typically offers a capacity ranging from 1800mAh to 3000mAh. In contrast, the 21700 battery can store significantly more energy, with capacities often exceeding 4000mAh. This increased capacity translates to longer battery life, enabling users to enjoy extended vaping sessions without needing to recharge.

Another significant difference between 21700 and 18650 batteries lies in their discharge rates. The discharge rate, measured in amps (A), determines how quickly a battery can supply power to the vaporizer. A higher discharge rate is essential for devices that require intense power pulses, such as sub-ohm vaporizers. The 21700 battery generally offers higher discharge rates, often exceeding 30A, whereas 18650 batteries typically top out at around 20A. This increased discharge capability makes the 21700 battery better suited for high-powered devices.

Safety is the primary concern when it comes to vaporizer batteries. Both 21700 and 18650 batteries have built-in safety features, such as overcharge protection, short-circuit protection, and thermal monitoring. However, the 21700 battery's increased capacity and discharge rate demand more sophisticated safety mechanisms. As a result, many 21700 batteries incorporate advanced safety features, such as internal fuses and pressure relief valves, to mitigate the risk of overheating, explosions, or fires. No one wants to be carrying a small bomb around in their pockets after all. 

The compatibility of 21700 and 18650 batteries with various vaporizers is another important consideration. While many modern vaporizers are designed to accommodate both battery types, some devices may be specifically tailored for one or the other. The 18650 battery, being the more established standard, is often compatible with a broader range of devices. However, the growing popularity of 21700 batteries has led many manufacturers to design devices that cater exclusively to this format. That’s great for you because it means there are lots of choices that use the same battery! That makes it fun to shop around for what suites your needs perfectly. 

In terms of cost, 21700 batteries tend to be more expensive than their 18650 counterparts. This price difference is largely due to the increased capacity, discharge rate, and safety features of the 21700 battery. However, the longer battery life and improved performance offered by the 21700 battery may justify the additional cost for many users.

The environmental impact of 21700 and 18650 batteries is also worth considering. Both battery types contain lithium, a finite resource that requires energy-intensive mining and processing. However, the increased capacity and efficiency of 21700 batteries may lead to a reduced overall environmental footprint, as users require fewer battery replacements and recharge cycles.

So really, the choice between 21700 and 18650 batteries for vaporizers ultimately depends on individual preferences and needs. The 21700 battery offers increased capacity, higher discharge rates, and advanced safety features, making it an attractive option for users who demand high-performance vaping. However, the 18650 battery remains a reliable and cost-effective choice for those with more modest vaping requirements. As the vaporizer industry continues to evolve, it will be interesting to see how these two battery formats adapt to emerging trends and technologies.
