What Are 18650, 20700 and 21700 Batteries?

Developed in the 1990s, the 18650 battery revolutionised lithium-ion power by providing a high-capacity rechargeable cell for portable devices like flashlights and laptop computers. It quickly became the go-to cell for small battery-powered products. Over the years, the 18650 battery improved so much that it eventually became the default power source for electric cars. Companies like Tesla continued to use 18650 batteries until higher-capacity cells became available.

The fact that the 18650 battery became so popular for rechargeable flashlights was the reason why it became the default battery for vape mods; some of the original vape mods were actually made out of modified flashlight cases. When the large vaping manufacturers in China began to make their own vape mods, they simply continued using 18650 batteries in their devices because those were the batteries to which the vaping community had become accustomed.

More recently, the 20700 and 21700 battery cells have entered the market to provide higher-density energy storage options for power-hungry applications like electric vehicles. Compared to the 18650 cell, the 20700 and 21700 cells offer greater energy density and excellent heat dissipation characteristics with only a slight increase in size. Thanks to those benefits, the 20700 and 21700 cells have become increasingly popular for use in vape mods. Whether they will eventually become more popular than the smaller 18650 battery, however, remains to be seen.

Why Buy Vape Batteries at Simply ELiquid?

The most important reason to buy your vape batteries here is because no company in the vaping industry works as hard as we do to ensure that every product we sell is authentic. That’s particularly important with batteries because a counterfeit battery is a potential safety issue. To ensure that our customers only receive genuine products, we manage our supply chain tightly and work only with original manufacturers and authorised distributors. The other reason why you should buy your vape batteries from Simply ELiquid is because we love bulk orders! When you buy from us, you’ll enjoy free shipping on any order over £30.

Why Is It So Important to Buy Authentic Vape Batteries?

Authenticity is important in the vaping industry, and it’s particularly crucial when you buy vape batteries. That’s because counterfeit batteries are extremely common – not just in the vaping industry, but in all industries. The only information that you have about the manufacturer and the capabilities of a particular battery cell are printed on the battery’s wrapper. A battery’s wrapper is made from heat-shrink plastic tubing, and anyone can print anything on heat-shrink plastic. It’s unfortunately quite common for unscrupulous individuals to buy used laptop batteries, remove the cells and place counterfeit wrappers on them. The old batteries are then resold as “new” cells from major brands, and the worst part is that, if you’re using the battery for an item that doesn’t require much power, you may not even know that you aren’t using a genuine cell. Vaping, however, isn’t a low-demand application; you need a battery that can deliver a high-amperage current safely, so it’s absolutely crucial for you to kno!

How to Choose the Right Battery for Your Vape Mod

The most important aspect of buying a vape battery is that you need to buy the right type for your vaping device. Most vaping devices use 18650 batteries, although an increasing number of devices work with 20700 and/or 21700 batteries. If you’re buying a new vaping device, you’ll want to check the product description to find out what type of battery the device uses and confirm that you’re buying the correct battery or batteries to go with it. The good news, though, is that a 20700- or 21700-based device will almost always include a sleeve to accommodate the smaller 18650 cells.

What Are a Battery’s Milliampere-Hours (mAh) and Continuous Discharge Rate (CDR)?

The two most important specifications you’ll see when looking at a battery are the cell’s milliampere-hours and continuous discharge rate. Milliampere-hours (mAh) refers to a battery’s capacity. If the rate of current is the same, a battery with a higher mAh rating will last longer before it requires recharging. For example, a battery with a capacity rating of 3,000 mAh can deliver one amp of power for three hours. A battery with a capacity rating of 3,500 mAh can deliver one amp of power for three and a half hours. A battery’s continuous discharge rate (CDR) refers to the rate at which current can flow from the battery continuously and safely. A good 18650 battery will have a CDR of around 20-25 amps, and a good 20700 or 21700 battery will have a CDR of around 30 amps. You will see some 18650 batteries marked as “35-amp” cells, but that figure refers to the battery’s pulse discharge rating. A battery can have a pulse discharge rating higher than its CDR because it’s assumed the battery will only operate at a higher rate of discharge for short bursts. As a general rule, you should operate a battery within its CDR rather than its pulse discharge rating. A battery’s discharge rating and capacity have an inverse relationship with one another. In other words, a battery with a higher capacity will have a lower discharge rating.

Use a Regulated Vape Mod for Maximum Safety

If you don’t want to labour too much over the finer points of vape battery specifications, the good news is that virtually every vaping device today has full power regulation features and will automatically shut down and/or display an error message if you ask the battery to do something it can’t. If you use a regulated mod, you’re fine with any high-quality vaping battery. Another thing to keep in mind is that you’ll get double the amperage headroom if you use a dual-battery vaping device. So, if you really enjoy cranking up the wattage, there’s no need to worry that you’re exceeding the capabilities of your batteries. If you install two 20-amp batteries in your device, you’ll effectively have a safe CDR of 40 amps.

Don’t Forget to Buy a Battery Charger

For convenience, a vaping device with a removable battery will usually have a charging port that allows you to charge the battery while it’s inside the mod. One thing you’ll discover very quickly, though, is that a built-in charging port isn’t the most convenient thing in the world if you only own one vaping device because most vape mods can’t vape while charging. It’s a much better solution to charge one battery or pair of batteries while using another, so don’t forget to add a vape battery charger to your cart before checking out!
