A single-battery mod with a 21700 cell typically operates at a maximum of 80-100 watts and has a battery capacity of about 3,000-4,000 mAh.A single-battery mod with an 18650 cell typically operates at a maximum of 60-80 watts and has a battery capacity of about 2,000-3,000 mAh.The primary benefit of buying a 20700- or 21700-based vape mod is that the larger battery cells offer increased energy storage and the ability to operate at higher wattages. In practice, most vapers are unlikely to notice the increased heat from 2070 cells. Tesla has mitigated that problem by adding extra vent holes to its 21700 batteries. The increased thickness, however, means that 2070 batteries dissipate heat a bit more slowly than 18650 batteries. While the 21700 battery is about 10 percent larger than the 18650 cell, its energy density is about 33 percent greater. Switching to 21700 cells allowed Tesla’s vehicles to offer about 300 watt-hours per kilogram of battery weight, compared to 250 watt-hours per kilogram with 18650 batteries. The primary benefit of 2070 batteries is that they have higher energy density for the weight than the smaller 18650 cell. Tesla’s vehicles began using 21700 batteries in 2018, and the cell is now available from a variety of manufacturers. Instead of switching to 20700 batteries, though, Tesla began producing the new 21700 cell developed in collaboration with Panasonic.

At one point, there was even news suggesting that Tesla was considering switching from 18650 to 20700 batteries in its electric vehicles. For a while, it looked like the 20700 cell might come to rule the vaping industry one day. The 20700 cell is slightly newer and offers higher energy density compared to the 18650 cell.

Although other battery cell sizes are also available, the 18650 cell has traditionally been the most popular type for rechargeable devices ranging from flashlights and notebook computers to vape mods and even electric cars. Based on that information, you’ve probably already surmised that a bigger number indicates a larger battery cell – and you’re correct.įor a long time, the comparison between 18650, 2070 batteries was irrelevant because 2070 batteries didn’t exist yet. A 21700 battery, meanwhile, has a diameter of 21 millimeters and a length of 70 millimeters. An 18650 battery, for instance, has a diameter of 18 millimeters and a length of 65 millimeters. The first two numbers refer to the battery’s diameter, and the second two refer to its length.

In the case of lithium-ion batteries, though, the model numbers do have a purpose because they denote the sizes of the cells.

After all, it’s just a series of numbers - and as you know, the model numbers for electronics often make little sense except to the engineers who designed them. On the surface, the numbers that people use to identify the various lithium-ion batteries might appear a little arcane. What Do the Different Battery Numbers Mean? If you’re stuck trying to understand the differences between 18650, 2070 batteries and aren’t sure which type of cell your next vape mod should use, this overview will help you decide. That may not be the easiest thing in the world if you’re new to removable lithium-ion batteries, so we’re here to help. That makes your decision a bit more complicated because you’re not just choosing between an internal-battery mod and one with a removable battery you also need to choose which type of battery you want your device to support. Today, though, there are newer types of battery cells available – most notably the 2070 cells. In the past, buying a vape mod with a removable battery always meant that you’d be using 18650 batteries because those were the most popular batteries for virtually all consumer devices.

If you’re in the market for a new vape mod, you’re going to need to choose between a device with a built-in battery and one with a removable battery – and if you’re shopping for a removable battery mod, that decision isn’t as simple as it once was.
