18650 Cylindrical Lithium-Ion Rechargeable Batteries

18650 Batteries at Grand Rapids E-Liquid

Rechargeable 18650 lithium-ion batteries are mostly not substitutable with their primary counterparts, but some lithium primary cells have rechargeable equivalents. Most rechargeable cylindrical cells use chemistry with a nominal voltage around 3.7 volts, but LiFePO4 cells produce only 3.2 volts.

Lithium-ion cells are made in various sizes, often assembled into packs for portable equipment. Many types are also available with an internal protection circuit to prevent over-discharge and short-circuit damage. This can increase their physical length; for example, an 18650 is around 65 mm (2.6 in) long, but may be around 68 mm (2.7 in) long with an internal protection circuit. Safe and economic recharging requires use of chargers specified for these cells. Popular applications include laptop battery packs, electronic cigarettes, flashlights, electric vehicles, and cordless power tools.

Commonly-used designation numbers indicate the physical dimensions of the cylindrical cell, in a way similar to the system used for lithium button primary cells. The larger rechargeable cells are typically assigned five-digit numbers, where the first two digits are the diameter in millimeters, followed by the last three digits indicating the height in tenths of millimeters.

18650 Battery chargers

Xtar, Ultrafire and Trustfire chargers have been found to be better quality than others on the market so far. Internal fusing, good separation between 240v and DC sides, 3 pin plug and CE marked. Xtar even sent copies of their CE certification. However, just  because a charger has a CE mark and a 3 pin plug is no guarantee of quality, or safety.  Please research for the best brand first before you purchase one!

Safety issues

At Grand Rapids E-Liquid we are watching as vape technology is advancing remarkably. Gone are those days of hardcore hobbyists modifying flashlights for vaping – now anyone over the age of 18 can buy powerful mods on the high street or with the click of a mouse. This explosion of choice is exciting, but that fancy little box in your pocket contains batteries that can easily become explosive in a very different way. But, considering the millions of people vaping in the world, effective problems are considerably low. However, a number of incidents have arisen from misuse of mods and poor quality merchandise, ranging from house fires to devices exploding. Whatever vape-kit you use for vaping, they all contain batteries with the potential for danger and so should be treated with proper care. The two most important points goes here below :

Use the correct charging cable. If your device charges using a USB cable, make sure the power output match your mod. If your charger has a higher voltage than your battery, you could overheat the battery or short the device. The best option is to use the cable you got with your product.

Don’t overcharge. Most well-made mods have a cut-off point where they stop charging when they reach full power. However this function has been known to fail on rare occasions, leading to them setting on fire. Only charge your device where you can keep watch on it, and never charge overnight.

Vape on!
