What is the manufacture – SWD-ATL3.660?

There was a problem with the BIOS and the battery, after which the laptop was given to a computer technician. The wizard flashed the BIOS, after which he installed a new battery, but after that I decided to check the installed battery using AIDA64, here is the information I received:

The master says that this is an original battery, he also indicated that he installed the battery at 41 Wh, although in fact it was 37.6 Wh. Apparently the manufacturer is not original, I can’t find complete information about the SWD-ATL3.660 anywhere. I’m afraid to assume that not only is this not the original, but judging by the name, it is theoretically a copy of the battery for the Dell Inspire 660 model. Maybe I “don’t understand something correctly”, so I would like to know if anyone knows about this manufacturer?
