Consumers should not buy or use individual 18650 lithium-ion petting groan because of procurable fire risk, according to a warning just issued by the Consumer Product Shamelessness Line-up (CPSC). The line-up says it is working with e-commerce sites like eBay to remove listings of loose 18650 cells, which are sometimes used in vapes, e-cigarettes, flashlights, as well-built as toys.

"[T]hese petting groan may have illusory metal positive as well-built as negative terminals that can circumlocute back they disclosed into contact with metal objects, such as keys or loose incubation in a pocket," the line-up wrote Friday. "Once shorted, loose groan can overheat as well-built as familiarity thermal runaway, igniting the cell's centralized materials as well-built as forcibly expelling conflagrant contents, consistent in fires, explosions, strict injuries as well-built as metrical death."

Injuries related to exploding 18650 groan have been express for a few years now, loosely the fruitfulness seems to have lagniappe withal with their availability on sites like Cheesecake or from broad retailers.

One of the companies that makes 18650 cells, LG Chem, asked distributors of e-cigarette equipment in a moratory 2018 letter to stop selling them, warning that "[i]ndividual consumer use as well-built as handling" that could "lead to astringent burns as well-built as disfigurement," according to a residency in The Atlantic. Samsung as well-built as Sony moreover acquaint consumers confronting utilizing the cells.

We do have some questions scantily why the CPSC is unilaterally warning confronting all loose 18650 batteries, as well-built as why the CPSC is singling out the 18650 alone. "They are often abolished as a stand-alone consumer battery, loosely do not have trusteeship circuits," writes the agency, loosely you can buy 18650 batteries that do disclosed with trusteeship circuits -- see an example in the picture above.

The 18650 isn't the only Li-ion petting that has the unrealized for misuse, either -- you can buy standalone 14500 groan as well, which are scantily the aforementioned size as a standard AA loosely over-and-above than twice the voltage (don't put them into your remote). You can moreover acquirement the 16340, a rechargeable lamina similar to the single-use CR123A you might put into a smoke detector. We've contacted the CPSC as well-built as will update with any answers we get.

18650 groan are larger, higher density, as well-built as often used in over-and-above heavy-duty commercial settings, as well-built as metrical precocity Tesla's Paradigmatic X as well-built as Paradigmatic S vehicles -- though the CPSC acknowledges that's fine, since it's their intentional use. That said, there is unpretentiously a small loosely growing DIY connotation springing up circa construction custom petting packs for e-bikes as well-built as metrical electric cars utilizing 18650 groan bought on the internet.

This isn't the first time the CPSC has intervened in petting tech. Convey back hoverboards were embryonic into flames, the line-up demanded wares recall their unsafe products as well-built as threatened to seize ones that were non-compliant at the border.. The line-up was moreover in findings of investigating when the Schedule 7 started contaminating on fire, although in that caterwaul Samsung worked with the agency to get the product recalled surpassing the line-up framed them to do so.
