Capacity (or mAh rating) is the approximation for how long a battery charge should last from 100% to cut-off.Volts are the power you’re applying to the current. Water flows easily through a big pipe (little resistance), and less easily through a tiny pipe (high resistance). All wires also have some element of resistance to them (measured in ohms). How fast it’s running is the current (measured in amps). Think of it like water running through a pipe. All electronics have current moving along a copper wire. Volts, amps and ohms are something you need to understand before you start poking around for variable anything devices.Few come with internal protective circuitry, so if you want this, you’ll need to fish around for added protection (third-party companies like Trustfire will do this Virtually obsolete, but still rocking the “Big Boys” image, these deliver the highest specific energy of any 18650 battery- at a cost. These are currently the most-common and most-recommended type Also wins points for safety and not requiring extensive built-in protective circuitry. Manganese allows batteries to discharge at a high current while maintaining low temperatures. These are high-drain batteries that exist because manganese is awesome. Lithium IMR a.k.a Li-Mn (Lithium Manganese).There are, however, several types of lithium ion battery. The vast majority of vape batteries are lithium ion- that’s the same kind you’ll find in your phone, laptop, cordless power tools and the remote control car you totally don’t own. The cathode is the part giving each type its unique characteristic. Lithium-ion batteries consist of three parts: the cathode, the anode and the electrolyte. Not many models take 26650s, but they’re around for powering the likes of some iJoy and Aspire devices.

26650 - less common and recognised by being slightly wider than 18650s, these (big surprise) are 22mm in diameter and 65mm height.On the clunky side, these are nevertheless power-pushing, long-lasting heavyweights that are used for one reason: they deliver. 18mm diameter, 65mm height and a “0” being the battery’s way of saying: “I’m cylindrical”. 18650 - giving millennials a throwback to flashlight torch batteries, these are found in the vast majority of mods.
