These batteries can be particularly volatile if handled inappropriately, such as putting them in a pocket or bag with metal objects like keys or coins. Buying from these authorised sellers confirms you are buying the genuine item with the best quality.Ĭarrying or storing these batteries should always be carried out with care, using the provided plastic storage case that our batteries are shipped in. The most crucial thing about buying 18650 or 21700 batteries is to make sure you purchase them from retailers that provide genuine products from authorised distributors, as there is a large counterfeit market. The higher the wattage you vape at, the higher the amount of amps to sustain that power. What we are looking to do is choose an 18650 or 21700, that will provide a happy medium between the MAH and an AMP CDR that will not only be safe, but also provide you with the longest run time. The higher the MAH rating of a particular battery, the lower the CDR (in AMPS). The most important part, the CDR (continuous discharge rate) in AMPS, the higher the CDR of the battery, the higher the current can be pulled from the battery without it overheating. First we’ll look at the capacity of the battery (or energy density) this is measured in MAH or milliamp hours, however this isn’t the only thing to take into account, as these can vary from as low as 2000mah up to 5000mah capacity. Now size isn’t the only factor in choosing the correct battery for your device, next is the performance capabilities of the battery. Using a simple WH (watt hour) calculator, you’ll be able see the superiority of the 1860. Even though the capacities can be relatively similar in the mah, the current drawn is mightily different with a 18650 or 21700. These cells are able to discharge current at up to ten times the amount of an AA. It's not just the size that’s different either, the chemical makeup is completely different as well, but most importantly the amount of power available is drastically different compared to your average AA.
The last number ”0” represents the shape of the battery, in these cases a cylinder.Īs you may have noticed there’s a considerable difference in size with batteries used in vape devices compared to that of, say an AA. The first 2 digits denote the diameter in these two batteries 18mm and 21mm, the second two numbers the length of the battery, 65mm & 70mm.
The majority of vape devices on the market that use external batteries will either be 18650 or the more recent addition to the vape battery world, the 21700. Vape batteries are made up of lithium ion chemistry, found in pretty much any device that's rechargeable from smartphones to the video doorbell, torches, power tools and laptops, to e-bikes and even cars, just to name a few.
