What is UL 1642 for Battery Cells on Amazon US?

Currently, Amazon has become the No.1 retailer of electronic products. It is known that 18% of sellers on the Amazon platform sell electronic products. However, as more and more sellers offer such products, the platform’s audit requirements have become stricter. For this reason, many sellers have recently reported that:

For Amazon US, car chargers, chargers, power adapters, and battery products must provide safety ul test reports. Car chargers require UL 2089 certification, chargers require UL 60950-1 / ul 62368 certification, and battery cells require ul 1642.

If you fail to submit these documents, your listing will be removed, meaning Amazon will revoke your selling privileges!
