Lithium-ion batteries operate in different voltage ranges based on the chemistry of the components, so an incorrect or counterfeit charger will not know how to “talk" to the battery in the right way. Counterfeit products pose many safety risks, as they may be prone to failure and cause fires and explosions.
If you see a 18650 Li-Ion cell over 3500 mAh, the capacity is fake. The maximum capacity may improve with progress, but very slowly. Also the weight of the battery can tell a lot. Real 18650 Li-Ion cells weigh about 40 - 48 grams. If the weight is lower, something is simply missing inside. Most fakes I came accross weigh only about 25 grams.
Law enforcement and airlines that carry cargo also keep an eye out for undeclared shipments that contain batteries, which is often in an attempt to avoid being caught as counterfeits. Still, counterfeiters’ determination knows no limits when seeking new ways to slip past such controls.
This study aims to show the response of high-quality and counterfeit batteries under two off-nominal conditions, namely, overcharge and external short, and describe how those results can be used to detect counterfeit cells to enable safer battery choices for various applications.
Off-nominal tests such as overcharge and external shorts can provide the information needed to confirm any cell designs suspected as counterfeit. Since all of these tests required specialized equipment and knowledge not available for everyone, some recommendations on avoiding counterfeit batteries are presented here.
In the present work, the compromise in safety with low-quality and counterfeit batteries is studied using 18650 cells. A literature review on the performance and safety of low-quality and counterfeit lithium-ion batteries returned zero results, indicating a lack of studies in this area.
