how to check date code INR18650 30Q

It is usually used to check the date code by https://batterybro.com/pages/18650-date-code-lookup-tool. but INR18650 30Q not code on wrap .

At bottom of page it says,

'What cells are currently known to not work with this tool?

The Panasonic-Sanyo GA, and the Samsung 30Q are both not currently functioning with this tool."

Maybe that is why it's not working?
