1. What is an 18650 battery?
The 18650 battery is a lithium-ion cell classified by its 18mm x 65mm size, which is slightly larger than a AA battery. They’re often used in flashlights, laptops, and high-drain devices due to their superior capacity and discharge rates. 18650s come in both flat and button top styles, and usually boast 300-500 charge cycles.
2. How long does an 18650 battery last?
Most 18650 batteries will last between 300 and 500 charge cycles, but battery lifetime can be extended far beyond those numbers if charged regularly before complete discharge. All batteries degrade over time, but you’ll often get over a year or two of life from an 18650 depending on your use.
3. What is the best 18650 battery?
The best 18650 battery depends on the needs of the device you use it in. You should choose an 18650 that is slightly above your device's minimum discharge requirement, and then focus on charge capacity.
4. What are unprotected 18650s, and are they safe?
Most batteries include protection circuit boards (PCBs) to monitor a battery’s discharge rate and internal temperature. Unprotected cells are often used by experienced users who build battery packs or use 18650s for electronic cigarette and vaping purposes, which often need higher discharge rates than protection circuits allow.
All of our unprotected lithium cells come with a warning regarding improper usage, and we encourage you to read it over before buying an unprotected cell.
5. Why choose lithium over alkaline chemistry?
Lithium batteries are a great option for today's high-end electronics as these cells typically have higher capacities than their alkaline counterparts. Although rechargeable batteries tend to cost a little more than standard alkaline batteries up front, these costs have reigned in because you won't need to replace rechargeable batteries nearly as often as alkaline cells.
