Safety Issue: Fake UL marks on battery chargers

The Eastchester Fire District would like to notify the public of an urgent safety issue concerning lithium ion batteries.


The discovery of a fake sticker in a fatal Queens fire has led the FDNY to seek out lithium-ion battery chargers that have a bogus UL insignia.


One way to identify a legitimate Underwriters Laboratories sticker: It will have the letters “UL” in a circle with the ‘U’ slightly higher than the ‘L.’ Counterfeit stickers often have the ‘U’ and the ‘L’ on the same line, investigators have found.


The following is a notification from UL Solutions that the Battery Charger identified (as seen in post picture) bears unauthorized UL Certification Marks. The battery charger has not been evaluated by UL Solutions to the appropriate Safety Standards and it is unknown if the battery charger complies with any safety requirements.


Name of Product: FN 48V Battery Charger. Online retailers identify the product as a battery charger for Electric Scooters.


Remedy: UL Solutions recommends that this product be removed from service.     

Identification on the Product: The battery charger bears an unauthorized UL Certification Mark and the following:

FN  48V



INPUT: AC 100-240V


OUTPYT: DC 54.6V   2.0A
