An 18650 battery is a standardised rechargeable lithium-ion cell measuring 18mm in diameter and 65mm in length, widely used as the power source in portable vaporizers. This particular cell delivers 2850mAh of capacity — enough to keep your vaporizer running for hours between charges. It is the same battery format used across dozens of portable vapes, torches, and electronics, making it one of the most practical spares you can keep in your drawer. If your vape takes an 18650 (check your model), this is the replacement you need.

Pair this battery with an external 18650 charger so you always have a fully topped-up cell ready to swap in. Grab two batteries and a charger together and you will never be stuck waiting for a recharge again. The Storm Vaporizer itself is also available if you need a full replacement unit.
A spare 18650 battery eliminates downtime by letting you swap a fresh cell into your vaporizer the moment your current one dies. A dead vape battery at the wrong moment is properly annoying. You are mid-session, the LED starts blinking, and now you are tethered to a USB cable for an hour or more. We have seen it happen to customers hundreds of times since we started selling vaporizers — and the fix is always the same: buy a spare 18650 and keep it charged.
The 18650 format measures 18mm across and 65mm long — that is where the name comes from. It is the workhorse cell behind most portable vaporizers, and the 2850mAh capacity on this one sits comfortably in the upper range for the format. For context, many budget 18650 cells ship at 2000–2600mAh, so you are getting noticeably more runtime per charge here. According to the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA), vaporizer use has grown steadily across Europe, which has driven demand for standardised replacement cells like the 18650. Battery manufacturers generally specify a safe operating temperature range of -10 to 60°C for discharge and 0–45°C for charging, so keep it out of direct sunlight and never charge below freezing.
One honest limitation: this battery is confirmed compatible with the Storm vaporizer. If you use a different vape that takes 18650 cells, it will almost certainly work — but double-check your device manual before ordering. Not every vape accepts every 18650 equally, and some devices are fussy about cell length if a protection circuit adds a millimetre or two. Flat-top versus button-top terminals also matter — the Storm uses a button-top, and that is what this cell has.
Replacing an 18650 cell takes under 30 seconds: remove the old battery, insert the new one with correct polarity, and power on your vaporizer.
The single best upgrade for any 18650-powered vaporizer is a rotation system: two batteries and one external charger. Here is something we have told customers for years: the best vape accessory is not a fancy mouthpiece or a cleaning kit — it is a second battery and an external charger. Rotate two cells and you will never wait for a charge again. One sits in the charger while the other runs your session. It sounds obvious, but most people do not think of it until they are stuck with a dead vape on a Friday evening. Typical 18650 cells handle 500 to 2,000 charge cycles depending on quality, discharge rate, and temperature, so a single battery lasts years of regular use before capacity noticeably drops.
The cell itself has a satisfying heft — about 45–48g, which is standard for a quality 18650. If a replacement battery feels suspiciously light, that is usually a sign of lower-grade internals. This one feels right in the hand and slots into the Storm vaporizer without any wobble or gap. Compared to the lower-capacity 2000mAh cells you sometimes find bundled with budget vapes, the 2850mAh here translates to roughly 30–40% more vaping time per charge — a noticeable difference across a full day. We tested both side by side in the shop last winter, timing sessions on a Storm set to 200°C — the 2850mAh cell consistently delivered 25–30 extra minutes before the LED started blinking. That is the difference between finishing a session comfortably and scrambling for a cable.
If you want to order a complete spare kit, look for the Storm Vaporizer, the 18650 External Charger, and this rechargeable 18650 battery together. Having all three means you are set for years of uninterrupted sessions.
It is a rechargeable lithium-ion cell measuring 18mm in diameter and 65mm in length. The format is standardised and used in vaporizers, torches, laptops, and DIY power packs. The 2850mAh capacity on this particular cell means it stores more energy per charge than many entry-level 18650s.
It is confirmed compatible with the Storm vaporizer. Most portable vapes that use the 18650 format will accept it, but always check your device manual. Some vapes require flat-top cells while others need button-top — verify before ordering.
Runtime depends on your vaporizer's power draw and your temperature settings. As a rough guide, most portable vapes get 60–90 minutes of active use from a full 2850mAh charge. Higher temperature settings drain the cell faster.
Typically 500 to 2,000 charge cycles, depending on how hard you discharge it and the temperatures it operates in. Charging at room temperature and avoiding full depletion before recharging will maximise the cell's lifespan.
Yes, if your vape has a USB charging port — the Storm vaporizer does include this feature according to its product manual. That said, an external 18650 charger is gentler on the cell and usually charges faster — we would pick an external charger over USB every time.
Keep them in a plastic battery case at room temperature, away from metal objects and direct heat. Manufacturers recommend storing lithium-ion cells at 40–60% charge for long-term storage. Never leave them loose in a pocket with keys or coins — that risks a short circuit.
Yes, as long as you use a battery case or silicone sleeve to cover the terminals. Bare 18650 cells can short-circuit against metal objects, which generates heat. A case costs almost nothing and eliminates the risk entirely.
You can get this rechargeable 18650 battery right here at Azarius. We ship from the Netherlands across Europe, and the battery ships safely in protective packaging to prevent transit damage.
